I'm not in the market for a new TV for another couple years, but my overall tips are:
- Costco for the 2 year concierge warranty + option dirt cheap extended warranty plan to 5 years for an extra $100
- Assuming the price isn't totally our of scope, you might as well try to future proof your TV with as many 4k/120/VRR HDMI 2.1 ports as possible (and affordable). Just because a TV says it has a great spec, it might be limited to just 1 of the 3 HDMI ports. The other 2 ports might be standard HDMI 2.0 ports
- As for going OLED, I can't offer advice as when I got my TV in 2017, OLEDs were just coming out and way too much. And I dont think think they had big OLEDs yet, since I wanted 65". They were just too much 4 years ago too so I didn't even give them a sniff, but I'm going to assume they are affordable now. But when I browse the tv section at Costco now, the OLED picture quality on display is awesome. The blacks do pop. Next time I get a TV I'm going to check OLEDs
