I just moved from a shared appartment to a new flat, so I can finally have my gaming PC in the living room, next to the TV.
I set up my PC with the desk and monitor in one corner of the room, and bought a 5m HDMI cable to connect the PC to the TV as well. But... It does not work.
Here is a 20s video of what happens:
The setup:
- The video card connected to the TV is an Gigabyte RTX 3080 Vision OC
- The HDMI cable is an Hama 00200704. From the specs listed on the box, it looks to be HDMI 2.0.
- The video card is also connected to a BenQ 3440x1440 monitor through Display Port, but the behaviour also happens when only connected to the TV
- The TV is an LG OLED65E97LA, 4K@60Hz
What I tried:
- Connect another PC to the TV using the same cable: I connected my Work Laptop (Lenovo ThinkPad T480s) to the TV, got a clean 4k@60Hz output, but without HDR
- Plug the cable in different ports, both on TV and video card: no change
- Plug the monitor to the card with another HDMI cable: no issue, the HDMI ports work
- Try to play with the Windows display settings (lowering resolution, changing refresh rate, enabling/disabling HDR, ...), no success
- Try to play with the NVidia control panel settings (GSync compatibility, refresh rate, ...), no success
What I did not try:
- Connect the PC to the TV using another cable: the PC is too far away, it would be a hassle to do. However, I already connected this PC to this TV using HDMI in the past, without any issue.
If you have ideas of what I can try or what could be ths issue, because I can't figure it out
