Nope, buying a good 4K HDR television is one of the best investments that you can make. I tell all of my friends to do that first, before upgrading weird, expensive pc components or buying redundant consoles. But you get what you pay for; you don't buy some piece of crap Black Friday TV.
There's a nice 48" LG CX OLED coming out this year for the first time and that's going to debut at $1499 so you
might be able to get one for ~$1100-$1200 around thanksgiving. 55" was previously the smallest size you could get in an OLED panel. Otherwise there's a fantastic deal on the first budget, entry-level 4K HDR TV that I could recommend in last year's TLC 6-series 55" R617 that you can score right now for
only $399. Those sets start at about $599, can have uniformity issues, and/or break easily, but that's the best entry level HDR performance in my mind.
Don't waste your time with any of the budget sets from the main big brand names.
The Sony 950G for $999 is the best overall value and performance that you can get in 4K LCD televisions right now. High brightness and excellent color contrast. But most gamers are going with an LG OLED these days because they are HDMI 2.1 compatible for high refresh rate gaming and their PCs. But new consoles aren't going to be able to push above 4K60fps on any new AAA titles anyways, just like the 2080 Ti doesn't do now. So I don't believe 2.1 to be much of a deal-breaker unless you're going for high VRR as a PC monitor. The new 2020 Sony 900H is the other option if you want a HDMI 2.1 compatible device but the brightness (and HDR) is going to be much lower.
Those are the 3 sets at different pricing tiers that I'd recommend. There's a high amount of diminishing returns that you get for your money spent after these price points.
- TCL 6-series LCD (last year's 55" @ $399)
- Sony 950G LCD (55" @ $999)
- LG CX OLED (55" @ $1799, 48" @ $1499, wait for sales. Or else get a C9 from last year for $1499)
