I got the frame 50 inch for my parents. It has only got a 60hz screen and doesn't support hdmi 2.1 . I find screen uniformity to be really good, didn't notice any dirty screen effect either. Contrast is fantastic, brightness has better than I expected too. Overall I'm quite happy with it, I use my PS5 with it as well (at 60 hz) and it seems perfectly at home while gaming ad well. Viewing angles aren't great because of the lack of a wide angle filter, so that's something you would need to consider. Screen reflections are not visible when watching bright content, however it is slightly visible when you have a bright light source opposite it . Software is quite smooth, I've only noticed very occasional stutters in performance of the software. Overall I'm really happy with this purchase, I didn't expect an Edge Lit set to be this good. Black levels are pretty good too , unless you watch it at night without any lights on, I find the blacks perfectly acceptable when you watch it in a room with a dim light source
