PC Drivers & Software

Hi I'm professionally using a WX8200 on a Windows 11 machine, mainly for CAD and programming. 

Looking for more "screen real estate" I bought a Samsung QN700B 55". 

I cannot get the Windows resolution to 7860x4320 with the WX8200. 

The QN700B only supports HDMI2.1 inputs. The WX8200 has 4 Displayport 1.4 outputs. 

I tried a passive Displayport to HDMI adapter and also an active one. Both state they are 8k capable. 

I have an RTX3060 in the machine for CUDA calculations, too. This will drive the Display properly with 8k resolution. 

But the WX8200 will not list the option to go to 8k. 

Is this supposed to work ? 

Thanks, 

Bart

I now checked on the Adrenalin and the Pro drivers and also made some EDID dumps. 

Reading the EDID with the EDID Editor from Analog Way I see there's a UHDTV 4320p resolution listed in the display modes on Windows and Linux, too. 

The cli tool dumpedid for Windows will only list the entries from the first 128 bytes as it seems, as the list stops at 3840 x 2160  60hz. 

I wonder if the missing 4320p resolution is a hardware or a driver limitation. 

I also tried setting the Pixelformat to YCbCr 4:2:0 and the color depth to 8 bpc.
