Tearing between different display computer(LED wall)?

[CamdenJayce]

i have 3 display computer and 1 production computer

 

each display computer is dell t5810 with wx9100 and s400.

 

each display computer’s wx9100 have 5 output for led sending card and 1 output for display computer monitor(only for control display computer, not for wo).

all led sending card’s resolution is 1920*1472 50hz

and all display monitor’s resolution is 1920*1080 50hz

i’ve setting up each s400 sync and wo6.4’s sync setting.

i’m sure each display computer’s 5 output are sync even without s400.

but still got tearing not sync between display computer.(only fast move video files)

i also try hap hapq mp4 and got same problem...

what else can i do ?

No, that's not the case. To framelock outputs on WXxxxx cards, you'll always need a S400 sync board.

What do you need this for? The WATCHOUT display software changes into Direct3D mode when playing content and does not run in WMI mode.

I've seen a lot of problems with graphic cards trying to send out custom resolutions. Have you tried to use UHD instead?

On the WATCHOUT side it would be easy to accomplish using virtual screens mapped onto real outputs.

I would first try to get your computers in sync unsing a standard resolution and then start exploring from there.
