Problems to Out 4x4k@30hz on WO 6.2

Recommended Posts

I have experienced problems to send 4 outputs 4k@30Hz . The computer recognize the 4 outputs , but when i start a watchdog the screen remains in black and the ip and logo don't appear! I set the producer preferences to 30HZ , to 29,97 ...... test all frequency rate. But when i use 3 outputs , all works fine , or even i use 4 outputs on 3200x1800@30hz too work fine!  Has any limitation in WO to do 4 outputs? I've experienced the same trouble in WO 5.5.2.   The system is running with FirePro W8100 , I7 5930X and Intel 750 series PCI SSD .

Hi Alegrt!

this is unfortunately a known issue with AMD cards. The issue is with 4x 4K when using DirectX9 applications. AMD has been duly informed about this, but has decided not to make a fix. If you are using NVIDIA cards this is not a limitation. 

 

There are several threads about this issue in the forum if you want to read more:

Hi, alegrt,

 

I feel your pain when we spend lots of money, I really hope AMD can fix this issue for you.

 

A question before buying an entire Dataton system, using 4 datapath fx4 (not sure you're familiar, I take 4 1920x1080 as one big UHD 3840x2160) and plugging them to a 4x4K will I be able to pull out 16 projectors feed?

 

Best,

 

J.

as long as you do not need blending or geometry correction
