Review: Good - The monitor is insane. First time I had an OLED and after a bit of use I can tell you that it is a game-changer, I use it for most of my media now as well as gaming and coding, the 4K resolution means that if I set the window scaling to 125% I can fit like at least 6 windows with readable text. Please make sure you have at least 80 cm space clarance between you and the monitor if you do get the 31.5 Inch version as the 24.5" and 27" inch modes for gaming are quite disappointing as they can only be used if you turn off Freesync Premium PRO (it will happen automatically if you do not), albeit it may be a technically unresolvable issue for them I don't know that fact... I know many other OLEDs don't have that issue. Text clarity is really good and I come from TN/VA panels and I can tell you there is a MASSIVE clarity/ghosting difference. The blacks are beautiful as well and makes viewing any media a breeze, albeit I'd make sure you are not near windows or have pretty good blinders to use the monitor during daylight. It's also very quick and responsive. USB cable is annoying to use. as for the Brightness it's veeeeeeeeeery briight if you want it to, depending on the game, but I wouldn't buy the monitor for it's HDR capability as it's pretty middle-of-the-road, and windows games in itself have TERRIBLE HDR implementations, it is mostly a gimmick unless you watch many HDR movies on your monitor - and even then the HDR only works with media players like VLC or MPV, so ,no, your browser won't have nice HDR. Value for the money I'd say it's good but definitely could be way better, if it weren't for the size mode issue I'd give it a 5 star.
Review: Amazing Monitor - Great for work and gaming. My preferred feature is the KVM, now I can finally drop my old KVM. Loving the looks and the resolution.

### ⭐⭐⭐⭐ Vibrant and vivid
*by D***N on 27 June 2026*

Great monitor. Vivid colours, decent height helps with immersion, adaptive sync prevents tearing really well. Knocking a star off as there seems to be a bug where the peak brightness in Windows display settings is listed as 240 nits. Using HDR calibration tool has seemingly fixed this, but ideally, this should work out of the box.
