Should my AVR be ok or new AVR time?

I've just got a LG BX OLED and I have an Onkyo TX NR 686.

I Know the amp won't do Gsync or 120hz 4k, but I was hoping to do ycbcr444 10bit at 4k 60, but it's not letting me select this in Nvidia control panel?

I suppose I could connect my laptop directly to the TV , it has an RTX 2070 so should do Gsync 120 and ycbcr444? Two points with this way though, seems a waste of AVR amp doesn't it? And secondly do I physically need a 2.1 cable or should the very new 2.0 cable be fine ?

I have also got HDMI 4K Enhanced selected

Which option is best for colours?

I did managed to get 4k 120 working on the 2070 but direct laptop to TV.

I'm assuming to have any improvement in PQ via AVR than I would have to stump up a lot of cash for a fancy AVR?

RGB will be best for desktop usage, 4:2:2 for games and movies.

The only thing you’d gain from a 2.1 receiver is HDMI pass through for those new features really, 4k120 etc.
How did you get 4k120 from a 2070? A clever DP->HDMI adapter?

Under PC resolutions in NV control panel, just a normal HDMi cable, evidently it's supported now it seems.

Should I be able to get 444 if connecting laptop directly?

 

[willhub]

so perhaps. gpu to TV directly < will a 5m 2.1 cable be OK?

Even my RTX3080 to AVR I can't select 444 10 bit, when I click info on the AVR it is outputting YCBCR 444 10bit to the TV so the receiver is capable. Very confusing.

How would an avr improve picture quality?

An avr is just a receiver. Where you should plug everything into it so you don't get audio sync issues.

However these days arc does very well so I plug into TV and use arc because avr are expensive to upgrade just for compatibility issues.

I'm assumed the AVR was limiting what pictures settings my computer was outputting.

I've never managed YCbCr 444 10 bit Full, only 8bit limited. The receiver however does always show 444 10 bit Full.

Apparently I would not have DTS in games if I use TV as a passthrough but can't say I've used DTS in a game so that probably doesn't impact me.

 

[willhub]

Yeah so avr don't improve picture quality.

They just pass through a signal. Some do upscaling but so does the TV so it's a mute point.

I'd plug directly into the tv personally and use arc for anything that gives me issues plugging directly into the avr.

I just felt I was "wasting" my AVR because I'd essentially not be using the HDMi inputs on the AVR.

I've tried plugging my pc directly into the TV whilst I now get Gsync I can only get 4k 60, YCBCR 444 8bit limited, it allows me to select 10 and 12bit but these cause the screen to go black and only way to restore it is to uninstall Nvidia drivers in safe mode.
