  1. Windows uses two different modes to drive a graphic card. So does WATCHOUT. Before WATCHOUT goes online, the display computer is in the GDI mode of the graphic card and to my understanding, the GDI mode is controlled by the Windows settings. When WATCHOUT switches to the online mode, it also switches to use the Direct3D mode of Windows to increase performance. In this mode you do not see any windows, menu bars,... and many computer games use this mode too when they run in full screen mode.

    I guess that the Lightware fiber transmitter uses the wrong EDID information. Being a fiber transmitter, you probably have to teach the transmitter the correct EDID for the needed resolution and frame rate. If you just copy the complete EDID set from your projector, your graphic card is sort of free to negotiate a resolution while the graphic card will try to use the preferred resolution of the display.

    The solution would be to teach your transmitter only the resolution it should use in online mode. This would force the graphic card to always use this resolution.

    Since you're using NVidea you should also read the posting

     

  2. AMD introduced some sort of power management in 2018 which will throttle down the speed of the graphic card when the system thinks that there is nothing much to do. Our favorite is still 2017Q4.1. We can't rule out though that a newer version of Windows behaves differently in combination with the various graphic card drivers.

  3. Are you absolutely sure that the videos on the screen are positioned to not show even one pixel on the next screen set?

    I've seen situations where I dragged videos onto screens and by accident they were one pixel off from the top of the screen (screen at 100/100 and video at 100/101). In your case, with no space between the screen groups, it would lead to pushing the content to the next screen set as well.

    If all your content is designed to fit one of the regions each, why not putting some space between the screens.

    The move command (Ctrl+M) and the feature to mark more than one screen and apply changes in one go helps to save time.

  4. I would try to adjust the shutter time. Most projectors run on 50 or 60fps. You might be able to force the graphic card to a lower resolution like 23.98 but this would probably require a programmable EDID manager behind the graphic card output or even better an active scan converter.

    Page 202 of the RZ970 manual states that the projector supports 23.98 at 2.048x1.080 and on page 200 I see 1.080/24p for the other inputs.

    A graphic card will only output such frequencies if the monitor's EDID states that the monitor can take it.

     

  5. Where did you grab the Art-Net data? On the WATCHOUT production computer?

    And are you really sure that you're sending the data on the right universe?

    I briefly checked the manual of LightKey. They start the addressing scheme from 1 while WATCHOUT starts the addressing scheme from 0.  So universe 1 in LightKey should be identical with universe 0 in WATCHOUT.

    A good tool to check where data is sent too is Artnetominator  (https://www.lightjams.com/artnetominator/).

  6. I actually can't see an active cable on their website.

    It should clearly say "active" in the description. The resolution doesn't say anything. The problem with AMD cards is that they only have two clocks driving the outputs whereas every output needs to be clocked. That's were the active adaptors take over.

  7. The actual question is: how many graphic card outputs are needed to fill your LED wall. WATCHOUT supports display servers with up to 6 outputs on one physical graphic card and you can network more than one display server in one WATCHOUT system. Each display server needs one license key.

    Apart from that, you'll need an extra license key for the production computer. This computer (often a powerful notebook) is needed to arrange your show and, in live shows, to operate the show. So the minimum number of keys needed is always TWO.

    BTW, if you are using more than one graphic card output for your LED screen, you should look for graphic card(s) with internal frame lock and/or sync boards!

  8. The file should be inside your WATCHOUT folder and should have a size of 1.952 KB.

    It could of course be corrupt or not properly registered in Windows. I would de-install WATCHOUT from this machine, delete everything left over in the folder (maybe except your show folder) and then go for a clean install. Doesn't take long and makes sure that WATCHOUT registers all components again.

    Sometimes, updating an older version to a new version can fail somewhere.
