I spent some time weighing these exact options last year. Given your $450 limit, you are honestly better off prioritizing motion clarity and VRR over a 4K label. Entry-level 4K panels often cut corners on response times which makes fast games like God of War feel muddy during combat. If you want a solid experience, the LG 27GR83B-B 27 inch QHD 240Hz is frequently on sale near your price point. It features full HDMI 2.1 bandwidth, so you get VRR and 120Hz support on the PS5. At 27 inches, 1440p looks incredibly sharp; you wont feel like youre losing that crisp feel unless youre sitting two inches away. For research, i would suggest looking at the technical reviews on RTINGS. They test actual input lag and ghosting, which matters way more than a box saying HDR400. TL;DR: Grab a high-spec 1440p monitor with HDMI 2.1. You will get better colors and smoother movement than a budget 4K screen.

Honestly, i would suggest being careful with the cheap 4k screens since the hdr is usually pretty bad. My experience with the Gigabyte M28U 28 inch 4K 144Hz has been safe so far. Just make sure to use the cable that came with your ps5 so you don't get flickering issues. It might be better than a budget screen since you get the proper vrr support anyway.

> the HDR on it is basically fake? ^ This. Also, be extremely cautious with HDR400 certifications! I previously purchased a display without verifying the peak brightness specs and the results were just disappointing. It was a total mess! You should specifically check for panels with high-quality local dimming zones. Without proper hardware, the HDR just looks washed out. Its amazing how much better the visuals are when you actually avoid those marketing traps!
