LG OLED 55 C9
Posted: 20 Jan 2020, 02:15
Hello everybody,
I have had the LG C9 for a week and use it as a monitor on my PC.
The current firmware is also installed and this brings VRR over HDMI.
However, the picture flickers when GSync is activated.
I monitor the frame times using RTSS. The flickering correlates with small frame time spikes. However, these are not so strong that e.g. the GSync range of the TV is undershot (40-120 Hz).
I have tested different HDMI cables, different resolutions, color depths, picture options etc.
You can hardly see the flickering. The flickering is most noticeable in dark scenes. With the cell phone camera, however, the flickering can be seen much more strongly with a 60 fps recording.
The problem seems to be most severe with UE4 games. Tested SW Fallen Order and Insurgency Sandstorm.
PC Specs: RTX 2080 1700X @ 3,9 16 GB RAM and 2 TB Intel 660p NVME

GSync is on for the first 10 seconds of the video.
GSync is off in the last 10 seconds.
Is the TV broken or is the flickering normal?
Thank you for your help
