Hi,
I recently bought an LG C2 42" oled as my main display.
I have a Radeon 6900XT graphics card, and I have problems getting 4k120 signal with a https://www.amazon.de/-/en/Cable-Matters-HDMI-Displayport-120Hz-black/dp/B094XR43M5/ cable to the LG C2.
When using a HDMI 2.1 I get a 4k120 signal without any problems.
With the DP - HDMI 2.1 cable, works only at 4k60, if I try to set refresh rate above 60Hz, the signal disappears.
Radeon software recognizes the C2 refresh rate only as 40 - 60 Hz with the DP - HDMI cable.
With HDMI 2.1 cable, Radeon software sees the refresh rate as 40 - 120 Hz.
I have 2 LG oleds connected to the computer, so I need to get 4k120 signal from one of the DP ports.
Tried from both DP ports, doesn't work with either one of them.
Uninstalled gpu drivers with DDU and reinstalled, no change.
