Beautiful OLED Monitor
Great monitor with amazing colors. The matte finish I am pretty used to and it is not overwhelming. I honestly prefer not seeing a reflection in my monitor as I sit right next to a bright window.I play a lot at night but I still use it during the day sometimes for work. Brightness isnât the BEST but it is more than enough for me to play competitive games. The screen protects itself in a way that whenever pure white is shown on screen it usually comes off as grey which I donât mind. For work it is a little adjustment/dimmer (when in pure white docs). Although for gaming, I donât need my eyes seared by every flash bang to be competitive, so Iâm not missing out there.HDR is ok but Iâm not a huge single player person and I typically keep it off most the time.A nice item for working from home is that I can power/display my usb c charging laptop with one cord to the monitor. No additional power cords/supplies are needed to plug into the monitor to charge my laptop ~60watts (I think) while showing a picture on screen. The monitor power cord alone supplied enough for itself and an excess of 60w to charge (the monitor cord itself has a larger power brick due to this). Keeps my desk clear of unnecessary/excessive cords.Response time is stellar and quality is top notch. No dead pixels. I really enjoy this monitor and the only reason I would ever change it is to upgrade from 1440p 240hz to a 4k 240hz monitor. Even then, 1440p OLED is almost perfect on a 27 inch display except text clarity is the only real improvement I would see from 4k resolution (OLEDs are typically a bit worse for text clarity).

Lightweight monitor with an amazing screen
Absolutely impressed,ive had this monitor 9 months ago,i use it every day for gaming,the colors are perfect,brightness is perfect,i love the inputs being on the stand,it is surprisingly small,i have a small cramped office space and it fits on a long stand up desk,for my needs,its the monitor Iâve been waiting for,i have a pc and both an Xbox series x and a ps5 hooked up to it,it shocks me how light it is and still has an awesome 4k screen,gaming performance is so unbelievably good,i canât believe the amazing response time,overall itâs amazing,but itâs expensive but amazon had a promotion that made if affordable by paying over a few months on my credit card,i would buy this again in a heartbeat

a great monitor with a feature that’s a little ahead of it’s time
This XENION Flex has amazing image quality and some advanced features that will probably become standard options in the future, but for which you are now paying quite a premium. First the positives: OLED has no backlight, each pixel is literally on or off, so the contrast ratio is excellent. That and the pixel transition times are so fast because of the OLED technology that no LCD can even come close. The screen is also enormous, so playing games or watching movies, especially in HDR, looks incredible. HDR is made possible, btw, by the high light output, nearly 800-1000 nits, which is fantastic for an OLED but merely decent for an LCD. The monitor is also 120Hz with Nvidia GSYNC and AMD FreeSync, so if you have the card to drive it you can get very smooth gaming.Now the negatives. Some people have dinged the monitor because, with it’s very large size but only 3440×1440 resolution, the pixel density is lower than what a typical 4k monitor would have. But for me this is more of a bonus than a downside. The argument that the density is too low is mostly about text. With less pixels per inch being used to create text the monitor doesn’t have the same level of crispness that a smaller 4k monitor would, but what usually goes unsaid about that is that higher density also makes the text on the screen smaller. Because of the large screen size and somewhat lower pixel density text on this screen is much more readable, particularly if you are middle aged or above. And while the text might be theoretically less crisp on this monitor, if there is any fuzziness to it I can’t see it, so all in all I actually appreciate the larger, more readable text.A downside that does bother me is the brightness. OLED screens get stressed when they push out a lot of light, so to compensate the monitor has some protections enabled by default. When you are on a screen, say a web page, for an extended period of time the monitor will begin dimming the screen to ease the stress on the organic pixels. Refreshing the page or switching quickly between pages brings back the light, but it can get kind of annoying if you are reading something and it feels like you are gradually losing the light, plus the transition back to bright can hurt your eyes a little. I think there is probably a way to adjust this, but the problem is that OLEDs are famously wanting in durability, so I worry that fiddling with this could shorten the lifespan of my very expensive monitor.Related but less annoying are things you don’t have to do but probably should do to protect the monitor, like switching off icon visibility on your desktop and setting the background to straight black to avoid the dreaded screen burn, which again OLEDs are particularly prone to. You should also probably set a screen saver that blanks the screen after 5 or 10 minutes of inactivity. Again, you don’t have to and the screen does have a 3 year warranty, but if you want the most bang for your buck this is probably a smart move.Finally, the major talking point about this monitor that, in my opinion, is neither good nor bad, which is the bendable screen aspect. You can grab the outside edges of the screen and push it flat or pull it into a sharper curve. Some people will never use it, but it does serve a purpose. For gaming, pulling the screen into a curve makes the games more immersive, but for productivity work I find flat is easier to work with. The neither good nor bad part of this is that while being able to adjust the curve is a very nice feature and one that I think will probably become standard a couple years from now when the technology is less novel, for now you are paying one heck of a premium for it. The monitor is easily 25%+ more expensive than comparable offerings where only the ability to define the screen curve separates the monitors. I made the plunge, but not everyone will see it as worth the extra price.Bottom line, if you don’t mind paying a little extra to be on the bleeding edge, this is an excellent gaming, entertainment, and productivity monitor whose technology still requires a little extra care be taken to preserve full functionality.

Llego muy rapido el monitor, tiene muy buenos colores y alta frecuencia de actualizacion de cuadros, lo unico que si me molesta es que tiene ghosting pero es muy dificil notarlo, la unica forma de quitar el ghosting fue desactivar la sincronizacion G-Sync y desactivando eso el monitor esta 10/10

Compré este monitor Corsair OLED en diciembre y, después de varios meses de uso intensivo, puedo decir que ha sido una excelente inversión. La calidad de imagen es simplemente espectacular: colores vibrantes, negros profundos y una nitidez que realmente se nota en juegos de todo tipo.Lo uso principalmente para gaming (FPS, RTS, MOBA) y el rendimiento ha sido impecable. La alta frecuencia de actualización y el bajo tiempo de respuesta hacen que todo se sienta fluido y preciso, ideal para juegos competitivos.Además, las herramientas que incluye para prevenir el burn-in son efectivas y fáciles de configurar, algo muy importante en monitores OLED. Hasta ahora, cero problemas.Muy recomendable si estás buscando una experiencia visual premium para juegos.
