I think most people missed Broken Hopes context. Most AV receivers do not pass anything more then 4k @ 60hz nor VRR, until Deonon's recently showcases SKU's.
So in the event of PS5 and Xbox Series one X, you would plug those into the LG OLED to leverage VRR and anything higher then 60hz @ 4k. In these instances, DTS would not be passed through, how much of an issue the DTS element is depends on the person's collection.
This does not just apply to next Gen consoles, what about next Gen High end GPU's, I am fully planning to hook this into the OLED to leverage higher then 60FPS @ 4k and also VRR. If next Gen GPUs come with 2.1, I will be able to leverage 4k@ 120hz, VRR and still pass through audio to my AV receiver perfectly.
Those saying the 2080Ti does not do 4k @ 120hz, well first that's not true for every game, AAA games with settings cranked up, sure. But likes of Fifa or formula 1 then it will do more then 60hz @ 4k. Through most AV receivers nothing more then 60 FPS will be passed. Ignoring 120 FPS, what about the likes of BF1 which do say 100 FPS with settings cranked up, or what about if you notch of demanding settings to hit 120 FPS @ 4k, or what about if you use a Dynamic resolution that still calls for more throughput then what most AVR's will pass through????
Do I think the next Gen GPU will offer as much performance as the 2080Ti, no likely not. However it does not need to in less demanding games of which there are also many on consoles order to achieve say 120 FPS in your Fifa with tweaked settings, optimisations.
