I have just upgraded Immersive Cal. and Display to the latest versions........and also printed the latest manuals.......
Well I really have not seen worse manuals ever !! I have spent ages trying to figure out how to get the setup correct and even asking for advice from
Nikola " who says to follow the instructions " I am starting to get a little pieved off !!
Have said all that, has anyone here that are running 3 Projectors on 3 separate computers with a 4th computer as Server have the same problems. I am not talking about people running Triple Head To Go. ( that is another item in the instructions that is not made clear )
On page 40 of the calibration manual, there is nothing to suggest what you need to tick or where you export or copy any of the areas that can be ticked.....in other words you can spend a week ( or longer ) trying to figure out what has to be done........I certainly have not figured it out yet.
I have only just learnt that it supposedly does the Blending by itself, even though that does not work properly, and then I have not discovered how to get a picture on 3 screens that you can re-do the blending.
Ok enough of my whingeing, perhaps someone can give me some good advice on this.................no I am not taking up lawn bowls yet !!
Cheers...................Brian W.
I have the exact same set up you have both on my home sim and on several sims at work. PM me - I might be able to help.

Hi Jim,Brian
Hi I am in a similar position, trying to apply the manual to my setup which is the same as yours. Any chance you could continue this dialogue in the open forum rather than PM?

David
We will keep it visible to everyone in the Forum :)

Many thanks

I am running 3 separate projector (computer) channels plus a server using WideView. Thus...a total of 4 computers. I am also using Immersive Calibration Pro and Immersive Display Pro.
It all works fine. I agree the manual can be a little daunting, but if you take it slowly all the information is there.
For the calibration I am using the "on screen" method, not the camera method. I believe it is actually more simple to use than the camera method, particularly if you are doing it for the first time. That is what I recommend. I can help with that method.
So Brian...let's start.....
First be sure that you are following the correct manual for what you want to do. For the "on screen" method you should be using the "Calibration Without a Camera" version of the manual. Do not use the one that is entitled "User Guide".
So my first question is: Are you following the "Calibration Without a Camera" method and manual?
If yes.....How far along have you gotten with the calibration process? For example, have you been able to complete the on screen grid mapping aligning the grid square overlaps?
If yes...Have you been able to generate the "ViewGroups.xml" files in Immersive Calibration Pro?
If yes....Are you having a problem implementing the ViewGroups method in P3Dv3?
I just need to understand where you are at with the process.
Fred K
Let me thank you all for your replies. Perhaps, if there are no objections, I can make a questionaire here, so that hopefully everyone may benefit from the results.

So the main questions I have at this stage relate to Page 40 and then the following pages up to page 47.
Page 40 needs some major clarification as to what needs ticking and where to save and what to do with what you save.
I have been using the software for a number of years with reasonable results, but the latest upgrade is difficult to follow.
I have always done the saving and use of procalibs and the .xml files without problems, so suspect I need to learn how the new way with ViewGroups are used.
So if someone can explain from this point on it would be helpful to say the least.

At this point the important thing is that the "Test Pattern" projected on your screen looks perfectly aligned. You do not need to make any adjustments here...the adjustments for gamma, slope, and gain that the manual refers to have to do with the overlap band brightness. You can adjust for all that later using Immersive Display Pro. Aside from that if the "Test Pattern" does not look perfectly aligned you need to go back and fiddle with things.

QuotePage 36/37.......Not sure exactly what and how this is implimented.
I agree....all that is a bit confusing. But the point of it all I believe is to ensure that the extremities of your alignment grid do not exceed the actual projected area. That is, the display software cannot adjust anything beyond what the projector projects. So in that regard I am careful to not exceed those limits when I am in the process of doing the grid alignment earlier on. Thus when I get to this point all looks OK, and I go on to the next step.

Hmmm....The important thing at this point is that in your export file you have a "Multi_XXXX.procalib" file each display projector (3 in your case) and a single XXXViewGroups.xml file. Looks OK from what you report.
Beyond that....
For View Groups you need to do the following for each client computer:
(1) Place the .procalib files in the Immersive Display Pro folder in each client (located in Program Files X86 or wherever you installed). You can place both the single and multi files if you want....but the multi files are the important ones.
(2) Place the ViewGroups.xml file in the P3Dv3 file located in "C:\Program Data" for each client computer. Important: Make sure that the name is "ViewGroups.xml"....Remove the XXX designator part from the file name!
(3) Start P3D...Go to Views->View Group Management...then...
Displays->Config 1-> nVidia.....Change Display ID to corresponding projector (I do this but am not sure if it is really needed)
View Groups -> ImmersiveCalPro....Set corresponding projector (that is, delete the others)
(4) Right click on the P3D window (not on the view menu)....Click on ViewGroups....Click on ImmersiveCalPro
(5) Close P3D
(6) For each client....start ImmersiveDisplayPro and load ProCalib files.....Right click -> Click "External Calibration" -> Load and save files
(7) Restart P3D....Right click on window to be sure that "ImmersiveCalPro" box is ticked.
All should be fine!
Now if you want you can adjust brightness and brightness gradient etc. for your overlap areas within ImmersiveDisplayPro. The thing is I have never been able to achieve that to my satisfaction. I also find that I need to periodically adjust the overlap grid.
So for those reasons I am now using a butted display setup rather than an overlap display. To achieve that I run a 4:3 display mode in 1600X1200 resolution for my Optoma HDs. The advantages are: (1) the overlap gradient area is completely eliminated, (2) there is a bit more tolerance regarding periodic adjustment (that is, slight out-of-adjustment is less noticeable), (3) there is greater pixel density covering the exact same screen real estate since my projectors are moved closer to the screen in the 4:3 mode and there are no "wasted" ("duplicated") pixels in an overlap region (this gives a bit sharper display), and (4) performance is a bit improved since there is about 8% less total pixels to generate. In particular, night flying is significantly improved with the butted method.
The disadvantage of course is that I have a fine line of demarkation at the butts. So it is a matter of preference in that regard. For me, once I get to flying I do not even have an awareness of such...the off-brightness overlap bothers me more. But I do realize that this is a matter of preference.
But all that is is getting somewhat off-topic here.

Many thanks Fred for such a detailed reply...........
Have done everything as far as I can tell, but am still getting an image on the screen that is not aligned correctly, even though the preview in Cal Pro is perfect.
I was going to insert some pictures here but It seems that I am not able to get them in.
One thing of note that you mentioned was right click on the P3D window to get ViewGroups and click on Immersive Cal Pro. For some reason there is no checkbox there and it does nothing when I click on ImmersiveCalPro.
So it seems I still have a problem with getting ViewGroups to function.
Up until then everything appears to be ok.
Will go and do some more testing and if I can find a solution will reply here.
Cheers...............Brian W.
Hi Brian and all the Guru's here.
I thought you sorted those problems out a while back, Brian. Sorry, mate, I'd have given you a hand, if I could.
The truth is, I been waiting to do another re-calibration with the new software and I been lazy just doing the old .fxml insert instead of using the View Groups.
Thank you to Fred for his generous info, I will follow his wonderful instructions now and see if I can circumvent using those darn pesky .fxml files!
I was also not aware of doing the final adjustments outside of Calibration Pro for the blending.
Thanx Guys, I also appreciate the great exchange of info that happens on this forum, it's worth it's weight in gold....
Frank
Gooday Frank, yes I had it working ok until I decide to upgrade !! I keep forgetting the old saying "If it ain't Broke "...............

Hmmm......That is odd. In that menu there should be 2 items for ViewGroups showing...."None" and "Immersive Calibration Pro" with a checked checkbox in front of it. So something has to be awry with your ViewGroups setup I think.
Also, for the picture that you posted are you absolutely sure that WideView was running? It could be that WV was not on and the exact positions of the aircraft were not synchronized across projectors which would result in that kind of discontinuity. But that really does not appear to be the case here I think.
This is disappointing.
Fred K
OK got it.............................
Had to go into C:\Users\mine\Documents\Prepar3D v3 Files and change the .fmxl file that I have saved for the start-up flight and get rid of the "windows" file that I had installed there for the previous version.
Then the box for Immersive Cal Pro was ticked of its own accord.
So all looks good except for the Blending.
Fred, you mentioned using Immersive Display Pro to re-do the blending. Not sure how you can do that with P3d running or do you use another picture somehow.
Again many thanks for the information Fred as that helps straighten out the manual a whole lot.
Regards...............Brian W.
That is good news!
For the gradient blending you do that outside of P3D.
Go into "Configure" at the bottom of the main Immersive Display Pro window. Explore there and you will find adjustable settings for your parametric settings (gain, slope, gamma). You can also adjust "black offset" and the blending gradient. There are several screen projection options for evaluating the changes on the fly.
Good luck with all that...I have never been able to get it perfect....reasonable but not perfect. Adjusting "black offset" to within a 0.15-0.17 range seems to help for me.
Fred K
Just had a fiddle with the blending in Immersive display, but is very hard because of the graphics. It really needs a full picture a P3D scene to get the colours etc all set.
I have to say that the new version seems a little smoother.
I have just bought an i1 Profiler to try and get the colours exactly the same on all 3 projectors which should help the blending.
Thanks for the info.......................Brian W.

Brian - Keep us updated on the i1 profiler results.
Fred K
Will let you know how this turns out.
I have to make a bracket to put the device on top of the shell to get enough distance from the screen as I tried it a couple of feet away which did not work.
...........Brian W.
I also was struggling with the Immersive Calibration manuals. :) However, I didn't have blending problems - for daytime flying blending was practically perfectly generated with ViewGroups setup from the first time - no adjustments applied.
Here is the daylight approach to Gibraltar - both blending areas are in the picture, but practically are not visible. Two thin vertical lines are actual physical gaps between the screen sheets. And my left projector is a different model and has a better contrast, different from two others.
https://www.youtube.com/watch?v=MAsZyLKSLg4 (https://www.youtube.com/watch?v=MAsZyLKSLg4)
So far I only did one round for warping/blending with Immersive Calibration Pro. Later will return to calibration for more precise grid alignments and will try to create the second version with blending for night flying.
Nick
Nick -
That is about the best I have ever seen!
Fred K
Great video Nick......wish I could get mine that good on the blending. I will keep working at it.
I suspect some of the problems may come from the optoma GT 1080 settings. Seems hard to get enough brightness on some settings.
The i1Profiler is not all that useful yet, as it needs a lot of instructions to get it all on the right track.
Enough to keep me busy I suspect.
............Brian W.
Nick
What projectors are you using?
Fred K
Hey Guys.
I hope that Brian is on the right track now.
As I said earlier, I am doing a week of maintenance and upgrades before I launch into my "No Visa Required" American/Canadian Tour.
Part of the upgrades and maintenance was to go back and do another calibration and blend, more applicable to night flights.
Thanx to all the valuable info here, I'm now going to go the view groups method instead of the old writing the .fxml script.
I started yesterday and one of the issues I've always faced when doing calibrations, was the accuracy of the distances between columns and rows.
So, I've adapted a few new strategies, based on the way some of the pro's do it.
Firstly, I started a new calibration using the latest software and saved out the file. I set all my measurements and parameters within the settings.
From that, I used the calculated distance of the column and the row, to produce a template (from thin MDF).
I then created, using photoshop, a page of red boxes with black cross hairs on them, and printed them on transparent sticky paper.
Then, I physically used the template to measure the distance, starting from the bottom of my screen, and place the stickers on the screen, at the appropriate points.
I know that you end up, using these methods, with accumulated error, so I did take this into account.
I ended up doing half the screen and to my surprise the accuracy was astounding.
I wanted to test this method, so I cranked up Calibration Pro and mapped the left screen according to the red boxes with the cross hairs.
The time it took to physically map the screen certainly paid off in the amount of time made up mapping the co-ordinates.
I was so impressed with the results. I still have the second half of the screen to finish tomorrow, but it will end up being the best calibration I've done so far.
Thanx again, to all of those guru's who contributed to this very worthwhile thread,
Frank

Is there a way in P3d to have the sim ONLY use the projectors with Immersive Display Pro and still have an extra monitor which is ignored by P3d to show all background programs?
I have been struggling to set up such a configuration. I am currently using one main computer for the sim and visuals on 2 projectors, 180* wrap and a third non-warped monitor to display the desktop and background programs.
The problem is that P3d keeps trying to use the third monitor along with the projectors. I have tried editing the displays.cfg but no joy.
The view on the projectors with immersive display is fine but the third monitor is also displaying another forward view. I tried changing the monitor to "panel only" but that produces some unwanted behavior like my mouse cursor disappears and the frame rates drop a bit.
Anyone doing something similar with Immersive display?
Please tell us the video card configuration you have and if you are using Nvidia or Radeon windowing of any kind for the out the window display going to Immersive.

I actually find this view (I set it to just 1024x768) quite convenient. I use it for the P3D menu (through Alt+Enter when neccesary) and other programs are showing in that monitor too.
I have a 980Ti
PJ-1 connected to HDMI
PJ-2 connected to DisplayPort with HDMI adapter
Monitor connected to DVI-D
Immersive display configured on displays 2&3 with nvidia setup as "extend these displays" per Fly-Elise instructions. Each display is setup as 1 projector in Immersive display and the monitor is set as "no projector" then I run the Calibration-Pro software and calculate multi-frustum and output those files to Display-Pro and select "external calibration" for each PJ display. When I fire up P3d the monitor also displays a forward view in addition to the warped and blended view on the PJ's.
Does that make sense?
Thanks!!!!!!!
Craig
The monitor is still trying to be used by P3d for some reason.
In one of my tests a while back I was able to get the extra monitor to display only a black "desktop" and then unticked the "black out desktop" in the graphics section of P3d and it worked but something changed in my fiddling with the warp and blending alignment and now cannot recreate that setup. I'm not sure how I got there in the first place.
Frank...........let me know how the blending went with you new re-cal. I am using a Laser from Bunnings to level all the screens, which is very easy.
I am still finding it hard to get a decent blend. I would be interested from anyone else running the Optoma GT 1280 projectors, what settings they are using.
My Optoma setup is:
Display Mode ........Bright
Brilliant Color.........10
Lamp Mode ............Bright
Gamma..................Standard
All the other Display Modes seem way too dark, so wondering if everyone else is seeing this as well.
One major question for the blending is, does anyone know how to get a picture from the actual P3D into the 3 projectors so we can use that to correct the blending.
...........Brian W.
Well another nice little trick from Immersive Display Pro ( Should be called Amateur) is that as had been suggested that to do a job on the blending I would try Display instead of Immersive Calibration and follow the latest Manual.
Well have a look on page 33 of the Immersive Display manual and then compare that to the picture I just took of it on my screen. None of the Flip rotate are there, the actual screens I brought up were not lined up as you can see and there is no way of moving the control points that I could find.
So as far as I can see no way can you get a blending result from this. As it also appears to be a waste of time trying to get any information from Nikola.
............Brian W

Brian
Have you explored clicking on the menu tabs for the window that you have open in the photo? Under one of those you will find blending parameter and slopes that you can play with. I am not at home right now so I cannot give you exact guidance instructions.
Fred K
First trick is to get the colours to match on each projector. At this stage I can move the slopes etc., ok.
The problem I am finding is that the control points only seem to move in one direction therefore I am not able to line the colour patterns up correctly.
It seems that the latest upgrade of Immersive Display does not match the PDF Manual.
The other factor is that I am unable to insert different pictures across 3 screens to get a better idea of the blending.
..........Brian W.
Brian,
Don't give up, but don't kill yourself yourself over colour matching.
It is the single hardest part of any visual system, harder then geometry and blending.
3 consumer type projectors will never match 100%, although they should be relatively "close".
If you haven't already, make sure ALL the colour* and bright/contrast/gamma settings are identical first before tweaking colours*.
Blending control points only work Left to Right and vice versa, so Im not sure what else you want them to do.
There are variables within each blend zone for fine tuning slope/gamma etc.
Nat
*color = colour Downunder ;)
Just wanted to say thank u all. Very enriching discussion.
Sent from my iPhone using Tapatalk
Thanks Nat for the good advice. I think I have discovered where the problem is.
I am using a screen paint called Black Widow which tends to dull the brightness a little which is what it was designed to do for rooms with a lighting problem, which works fine if that is applicable.
Therefore I have been using the brightest modes available. What this is doing is lighting up each side of the blended area which I am unable to cancel out.
So I have gone to a duller mode and this seems to cure the problem of the bright areas.
I then think I should re-paint the screens with a ceiling white.
Will update further when I do some more work on the problem, which maybe of benefit to others.
...............Brian W.
Brian
Try deleting the contents of your "shaders" file. P3D will rebuild it when it launches. Sometimes that can make a big difference in brightness, particularly if you have added a bunch of scenery add-ons. I do that periodically as basic maintenance.
Fred K
Couple of really salient points here, bought up by Nat.
I learned the hard way, that you do not calibrate your displays (for colour matching) within Nvidia Settings panel.
It really does an excellent job, but next time you update Nvidia...it's gone, no way to save between updates.
I read somewhere that you need to keep your Contrast low, as this helps with the night time blend, so I tried it and it worked.
I'll have a look what my visual settings are on my GT 1080's Brian and we'll compare.
As far as the blend and merge go, the re-cal I just did, Brian, is the best I've done yet....haha sneaky, I actually saw that on Nat's site, but don't tell him...
I did my output files, but as for putting them into the view groups...mama mia, what a horrible piece of software.
I installed the output view group files into P3D and they come up in P3d, under view groups, but as to how I get them to operate from there....I re-read these comments from Fred, but I'm a little lost.
So, I went back and re-read the latest manual about another 4000 times, (don't want to exaggerate too much), but I am still none the wiser.
I'll be back to it tomorrow and hopefully figure it out.
Frank
I just re-did mine as well....................success !
First trick is to make sure all 3 projectors are the same settings.
BIG TRAP................Doing the settings on number 3 projector and inadvertently Number 1 projector picks up the Kryptonite rays from the remote pointed at number 3..............if that goes un-noticed it will lead to all sorts of troubles as I found out.
The new blend is the best so far, but still on some areas is a little on the bright side, so again the need to keep the overall brightness down a shade.
Frank I agree it is the worst instruction PDF I have seen. Fred's help was 100%.
When you copy and paste the 3 different multi.procalib to each computer into the Immersive Display folders, then backup the original ViewGroups.xml in each of the 3 computers In the C:\Program Data/Lockheed Martin/P3dv3..................then put the new ViewGroups.xml into each of the above folders.
The next part is confusing, but it does not seem to require as much as indicated, which seems to go when you do a re-start, I found, in P3D.

Craig,
Try connecting the LCD monitor to the internal VGA on your MOBO.
This is what I do and P3D ignores it completely. I have 3 projectors on my GTX card and one LCD on my MOBO VGA card and I cannot live without the LCD!
When you do the connection the display ID numbers will change and if you are using ViewGroup in P3D, you need to renumber the DisplayIDs in the View Management section.
Ammar
Brian,
Sorry to hijack your topic but I have a quick question which has to do with Immersive Calibration and Display Pro, and all the gurus are reading this topic, so please excuse me:
I have 3 Optoma GT1080 projectors with a 2.5m radius screen. My Optoma's are now placed at around 2.8-2.9cm from the screens so that I get full coverage of all screen parts with the projector beams.
My problem is I am using a 4 column overlap between the projectors when each projector covers 15-16 columns, that is about %25-%28 overlap which I read is supposed to be better than a small overlap!
This setup is causing problems with calibration and getting the lines and points to truly align especially with pixels looking as big as 3x3mm if not more! Lines and points really look jagged and very rough and it is ridiculous trying to align lines that look like ladders!
I am also getting a very bad blend over this wide area, so I am thinking of moving all projectors inwards and at distances closer to the screen at around 2-2.1m. I think this may give me a crispier image (smaller pixel sizes as I get closer to the screen) and I will lower the projector overlaps to around 2 or even 1 column (32cm).
In my cockpit the projectors are throwing at 2.8m from the screen but I am looking at the side screens from about 2m away and I can see the pixels! i cannot read any Taxi way markings and there is no way to focus them, the resolution of 1980x1080 on such large screens is simply not enough!
So, any advice before I go ahead and start this messy process?
Is there any "rule" as to what the pixel size should be for an acceptable image? I mean when I see pixels that are 3x3 or 4x4 mm whatever they draw will look blurry and unnatural if you are close to the screen! We know that the smaller monitors give a "clearer" image even at lower resolution.
Thank you.
Ammar
Gooday Amar........ok you should be close at those figures. Mine are as follow just to give you some comparison:
Screen radius............2.3 M
Height of screen.........2.0M
Projector to screen......2.2M
Overlap each screen....370mm
Uses 30 lines.
Middle screen covers....3050mm
side screens cover........2975mm
Height of screen projection....1725mm
Now with those settings you will only just see pixels if you are lucky, on the left hand seat looking left.
That is as good as you can get at 1020p and I am certain you should have very readable signs at that size. Mine certainly are.
Hope that helps...............Brian W.

A very good day to you Brian.
The major difference I can see is the projector/screen distance, you have 2.2m and I have almost 2.8m. That must be it for the pixel sizes and clarity! Do you agree?
You also seem to be using a smaller overlap than I do, only 370mm for a 3050mm (or 2975mm) screen covers, that is about %10, while I am using more like 1200mm for 5280mm front cover and 4950mm side cover!
I may have to move the projectors closer to the screen and go through the screen/projector calibration process, yet again!
Thank you for your feedback, I will always appreciate any advice you have.
Bless you.

Almost all of your problems with this "random" placement of projectors and screen would be eliminated if you used Immersive Display Designer first, to build the architecture for your system, then move to Immersive Calibration Pro for the alignment.

Believe me I have tried! I bought the software and it was the first thing I tried, BUT it did not do me any good, not a bit!
Maybe I could not understand the manual! All the manuals from Fly-Elise need to be re-written and made clearer!
Last night I tried it yet again hoping to figure out what use it would be, it was simply of no use! I really do not know what to expect from the software? Where to locate the projectors relative to the screen? I wanted the software to show me the projections on the screen without having to do it physically, and I suppose that is the main purpose for the software!
The software lacks the ability to adjust the projectors keystone value (set at 1 only on my 3 Optoma 1080 projectors) and produces very weird shapes on the "screen" that are not even close to what I have in real life!
I am happy with the trials I have done and the little geometry I still remember from high-school! :-\
Sorry that you are having such issues. The first thing I would do is remove all keystone values that are on the projectors.
Let Immersive Display Pro and calibration software handle all of that.

I will probably be doing this in the coming few days.
I will report back any changes.
A quick update after doing the following:
I moved the projectors closer to the screen to around 2.2m each (center is at 2.5m),
I removed the keystone of the projectors, all now set to 0,
I set the overlap to only about 37-40cm on both sides of the center projection screen,
I re-calibrated with Immersive Calibration Pro using the very easy "No-Camera" method,
I took the "Viewgroup" resulting file and applied it in P3D,
THE RESULTS are:
A much clearer (crispier) image, I now can only see the pixels when I move closer to the screen and then they are around 1x1mm (instead of 3-4mm), so the image looks much better and colors are more vibrant,
The smaller projectors overlap results in a blend area which is brighter than the rest of the screen, but you get used to it and it is more or less visible depending on the scenery, I tried changing the blending curves but not much can be done!
Reduced the FOV from 235° to 216° which is more than enough for me,
It may be my imagination but I now have less flickering (where a few pixels change brightness is the best I can explain it).
My advice to people with projector setups is to try to move the projectors as close as possible to the screen, the difference is really noticeable and well worth the trouble of reworking the setup.
