Hello,
I recently switched from a 3440x1440 34 inches display (LG 34GN850P-B) to a 3840x1600 38 inches one (LG 38WN95CP).
The previous screen supported 144Hz refresh rate without any problem when connected to the KVM. The new one not so much apparently.
Up to 75 Hz, the display on the 38WN95CP is flicker-free. At 120Hz or 144Hz, it starts flickering with banding artefacts.
When the screen is directly connected to the GPU, I get a flicker-free display up to and including 144Hz. The issue starts when adding the 8KSW21DP-DM KVM to the loop.
I replaced all the cables with DP 2.1 8K@120 Hz certified ones.
When directly connecting the GPU to the screen, the cable works just fine at displaying 3840x1600@144Hz. All connections to the KVM are using the same cable types and brand (DP 2.1 8K@120 Hz certified).
I checked the KVM firmware version and it’s on the latest 1.0.2.
As the resolution 3840x1600 is just below 4K (3840x2160), I assume it should be supported up to 165Hz as well.
Could you please fix the display issue when using 3840x1600 resolution with a new firmware update?
Thanks in advance.
Cheers,
Xavier
