This is a bit long but I'm trying to learn more about TV's and receivers so please bare with me.
I've been using my PC setup for everything so I've never had a need for a TV (I have no experience with modern TVs as a result) and my receiver knowledge has been pretty basic in terms of hooking things up due to the simplicity of my setup. Currently I have my setup like this between my PS4, Monitor, and Receiver...
PS4 -> Receiver via Optical
PS4 -> Monitor via HDMI
This setup will not work with the new PS5 because unlike the PS4, the PS5 does not have an optical port. I plan on buying a TV and PS5 at some point and am trying to learn more about how the setup would work best. One option with a PS5 setup would be this...
PS5 -> Receiver via HDMI
Receiver -> Monitor via HDMI
But I would much rather have my PS5 connected straight to the TV to avoid any input lag or video processing from the receiver which may degrade the picture quality/performance. Some receivers have minimal processing or even settings to disable processing but I'd rather bypass the entire thing by connecting the console directly to the TV. This is where I'm trying to learn more about ARC and eARC. I've never had a TV and never used ARC so I'm a bit unsure. Here is the setup that I'm thinking would work best...
PS5 -> TV Via HDMI
Receiver -> TV via HDMI ARC/eARC
With this setup, since the PS5 is connected directly to the TV while the Receiver is connected to the TV via ARC/eARC, would this mean that the Receiver is ONLY responsible for audio and as a result will have no impact on the video output?
