Fantastic quality - Truly amazing quality especially with its high resolution. Plenty of ports and of course excellent contrast because of the OLED panel.

GoretexOct 20, 2026 · Verified purchase ★★★★★

Great monitor - Upgraded from 34" and it looks great. Outstanding colors and brightness. Text is clear. Good uniformity with little edge dimming which is why I chose this over the Alienware AW36926QW.

Nice, big display - It's bigger at home than what you see at the store (pause) but it is very sharp and bright, compared to other OLEDs I've had. I'll probably return it because it is a little too big for what I intend to use if for outside of gaming. QD-OLED is still king, but this panel gives it a run for it's money with some adjustments. You can hardly tell the difference in color but when I put my QD-OLED next to it, I can see some differences, especially in the smaller details. What you need to understand is that this is a 5K display first, so if you have anything less than an RTX 5080, you'll be playing at a choppy >30fps at med high - max setting which defeats the purpose of using this as a sole gaming monitor. I was able to get around 60fps on the new Gears of War E-Day but it would still occassionally get choppy. I ended up dropping the settings to 4K for smoother play. The build quality is pretty solid and not hard to put together at all. Maybe 5 mins tops. One thing I really like is it has internal speakers so I don't have to always power my speakers for things outside of gaming. They are NOT great, but good enough to get work done or do a conference. The curve is not as bad but I can see the lamp "sheen" behind me, and because it's curved, if the light shines on either side, it'll stretch the sheen a little further than what a flat panel would. Overall, I'd recommend this monitor but for the folks that have other things to do with it outside of gaming (ie productivity/creativity)

Replaced my 42" OLED, no regrets - I was running a 42" LG C2 as my desk monitor, I have had it for a few years and after a year of heavy daily use getting started back up in my masters program it started showing uneven brightness on dark backgrounds. I was choosing between this 39" 5K2K and the 45" models; the 39 won for my setup. It's nearly the same width as the C2, and the curve let me push it back into the corner and open the desk up. I raised it to eye level, which gave me room underneath for my Mac mini and drive, and it sits cleanly between my MacBook and iPad on vivo mounts! Text is razor sharp at 5120x2160, which matters because I write and study on it for hours every day, mostly on dark backgrounds. Blacks are true OLED black, and the panel is bright and clean. This monitor is TOP SHELF! Shout out to the manager at the Yuma store. He's taken care of me for five years and walked me through the protection plan options so I bought with confidence. Get the plan if you use an OLED as a daily monitor.
