To be fair the Q90r was a brilliant set the only issue I had with it was it only had one hdmi 2.1 port . Ontop of that 4K at 120 hz was glitchy sometimes I would get hdmi hand shake black outs. So if I wasn’t a gamer I would of kept it.
Im with you on the too expensive part I bought mine in June for 1799 and now they are 1599 . For what it’s worth if you wait 6 -7 months after the release of a new tv you will save about 400-500 pounds .
This gives you plenty of time to decide on a new set should that be the case.
Yeah hdmi 2.1 is going to be glitchy for a id say a few years, it always takes tv the audio/visual world ages to catch up with bug free and reliable performance. We still have hdmi 2.1 certified cables that don't work, too many manufacturers and too many equipment as usual.
You might be able to find HDMI 8K 2In 1Out Switch boxes or better switches on amazon or ebay that maybe able to add a work arounds with more ports/switches and maybe better compatibility chipset but that is an unknown since its still too new.
nice video here showing LG OLED over Samsung Neo comparision
I do like the OLED better but id like to see how Samsung QD-Oleds do hopefully find out in 2022.
