Hi there,
Been lurking here for quite a few years but finally decided to take the plunge. Question relating to optimal connections to get 120hz from the CX Oled from various sources.
How should I connect? Until today I have one HDMI (not sure if it's High Speed with ETH, and it's running in the wall hence reluctance to move the TV and check) connected to ARC/eARC port on the CX which runs to the Sr7012 receivers ARC port. Both have the latest firmware installed. Marantz claims that a firmware update will ensure eARC support on the unit.
I have then subsequently connected the PS4 and PC to the receiver.
When running PS4, the CX enables game mode and Dolby Vision, audio goes through AVR and into the 5.1.2 speakers. I am guessing this is correct and getting 120hz?
However, when trying to play GTA on the PC, connected to the AVR, things look poor. Stuttering and low FPS. It's a decent PC with a Ryzen 7 3700X, 32gb ram and a Radeon 5700XT, which is ample power to push 60+ FPS at 4K in GTA.
Could it be the cable that is too slow?
How have you folks connected similar setups and are you getting 120HZ from gaming PC's?
