I’m trying to get 4K 120Hz playback from my gaming PC (3080ti) via my Denon AVR-S960H to my Samsung QN85QN90AAFXZA TV. All devices support 4K 120Hz.
AVR Connections:
- 5 inputs are 4K capable (CBL/SAT, DVD, Blu-ray, Media Player, Game).
- One input is 8K capable.
- Outputs: Monitor 1/ARC/eARC and Monitor 2.
TV Connections:
- HDMI 1 & 2: Standard
- HDMI 3: eARC
- HDMI 4: Gaming
Currently, connecting my PC to any AVR input and then outputting from Monitor 1 to HDMI 3 on the TV limits me to 4K 60Hz. Direct connection from the PC to HDMI 4 on the TV gives 4K 120Hz.
Should I connect Monitor 2 on the AVR to HDMI 4 on the TV for 4K 120Hz? Will my speakers still work? Or should I directly connect the PC to the TV and figure out how to route the audio through the AVR? I don’t currently have another HDMI cable to test this, so before I go out and buy one, I just want to work through my options.
Any assistance would be greatly appreciated. Thank you.
