Quad Monitor Workstation Issues

I am wondering if anyone knows what is causing this issue, or how to fix it.

We have just set up a 4-monitor workstation. When we run DeltaV Operate all 4 main pictures and toolbars etc. load, however they all load one on top of another on monitor #1. If only the 2 monitors on the first graphics card are plugged in, the 2 window view works fine (Pictures loaded into each window). Any other combination and it does the same overlapping as the 4 monitor setup.

Info about the setup:

  • DeltaV Operate expands to fill all of the screens automatically.
  • Windows recognizes all of the monitors, and all monitors are plugged in as suggested in one of the Whitepaper articles. We have also tried several other configurations including the Books Online suggestion.
  • Looking at the FRSVariables after switching to run mode, all of the "Monitor found" parameters show as false, and the primary monitor number is set to 1, while all the rest are set to 0 (they should be some combination of 1, 2, 3 & 4)
  • Same issue is happening on a second system as well.
  • Full screen on run is turned off.
  • Running DeltaV 11.3.1 on Windows 7

I suspect the problem is that we are currently setting up this system using an SI key and therefore it is not finding the correct multi-monitor license file. We have previously set up other 4 monitor stations running on a normal consumer license with no issues.

    Earlier this year I had the same issue.  

    I believe it  was the type of video card that was causing the problem.

    There was a hotfix that resolved the problem.

    Another possibility is the screen layout is not a supported layout, monitor 1,2,3,4 must be in the correct order, see Books On Line to check this.

    In reply to Chris:

    Also beware, if you have any errors in your Layout file, there will be no error dialog, Operate will simply ignore the file.  Unless Emerson has fixed this in v11.3.1

    We are working on getting the Hotfix installed, which we hope will work. However we don't have the Active support license for this system apparently, so we are waiting on our local Reps to see if they can come up with a solution. Fingers crossed.

    The joys of requiring a license to make a product work as advertised.

    Dell made a change to the video card hardware in the T3500, R5400 and R5500 computers back in the early summer.  To tell if this is what is affecting you check to see if the video card is an ATI FireGL V3750 or an ATI FirePro V4800.  If it is the V4800 then you will need at least DeltaV_1131_WS_04_CSS installed.  However the error that results from the video card change manifests as an error message from what I’ve seen, not a stacking of the graphics into one monitor so that may not be your issue.
     
    I’m thinking you have a usersettings.grf file that disables multi-monitor initialization.  Take a look at the VBA script in usersettings.grf and search for gn_mh_disabled.  If the line that it appears on is uncommented and that variable is set to a 1 (or gn_mh_disabled appears anywhere else in the VBA script and gets set to a 1) then the multi-monitor is disabled.  It may be disabled globally for a reason so leave it disabled there and create a workstation specific settings file for your quad head and set that value to a 0 in that settings file.  The usersettings.grf file will tell you how to create a workstation specific version.  Should only take you a few minutes to try and see if that fixes your problem.

    Installing Hotfix DeltaV_1131_WS_06_CSS worked.

    Closer inspection revealed that the Graphics cards had been changed since the last working setup we did.

    Thank you for your help everyone.
