OLED all the way! I switched from a Samsung QLED to an LG C4 OLED last year and the difference is night and day. The blacks are truly black, colors pop like crazy, and input lag is practically non-existent. Yeah, there's the burn-in concern but honestly if you're not leaving static images on screen for hours, you'll be fine. For your budget, look at the LG C4 or C5 series.

I'm with the others on the LG recommendation - those panels are incredible - but if you're looking at this from a long-term reliability perspective, there are a few extra things to consider. I've been testing displays for years and honestly, while OLED is great, you gotta think about your specific environment and how much you realy game. Anyway, here are three options that balance performance with long-term peace of mind: * LG C3 OLED - Since the C4 is out, you can get a C3 for a steal. It's basically the same high-tier gaming performance (4x HDMI 2.1 ports, G-Sync, Freesync) but with a more proven track record for panel stability. The firmware is super mature now too.
* Sony BRAVIA XR X90L - This is the best 'safe' bet. It's a Full Array LED so zero burn-in risk. The "Perfect for PS5" features like Auto HDR Tone Mapping are realy handy, and the build quality is tank-like compared to thinner OLEDs.
* Samsung QN90C Neo QLED - If your room gets any sunlight, this Mini-LED is the way to go. It hits 2000+ nits easily, which blows OLED out of the water for HDR pop, plus no static image retention issues to worry about during long sessions. Just make sure you don't skimp on a good surge protector too. OLEDs are sensitive to power fluctuations tho, so factor that into the budget.

Exactly what I was thinking
