The Corsair Xeneon 27QHD240 OLED is an excellent 27-inch OLED gaming monitor. When it first launched, it had a sub-par image brightness in SDR mode, when the Brightness Stabilizer – a technology aimed toward taming the Auto Brightness Limiter – was activated. Luckily, I got to test it after Corsair released the V103 firmware update, which addressed that exact issue. As it currently stands, the Xeneon 27QHD240 OLED manages to reach 200 cd/m² SDR brightness with Brightness Stabilizer on, and that not only makes it completely on par with other monitors based on the same LG Display's WOLED panel, but also a completely viable choice for gamers who aren't spending most of their days in complete darkness.

Where Corsair differs from the competition is the 3-year warranty, which covers OLED burn-in, and the design of the monitor. I really like that all of its ports are rear-facing – they're much easier to access and use that way. That's particularly important when we take into consideration that the Xeneon 27QHD240 OLED has an integrated KVM switch and a host of 5-gigabit USB ports. One of its two USB-C ports offers DP Alt-Mode and 65-watt power delivery, making this monitor a capable laptop docking station of sorts.

With that said, I don't consider this to be a particularly good choice for productivity. Yes, you'll get all of the benefits of a capable OLED panel, but also its biggest downside – unappealing fringing around text elements, caused by the RWGB subpixel layout. Because of it, text won't look as sharp as you'd expect from a 27-inch 2560x1440 panel, and if you're spending most of your days working with text or graphics, and only game occasionally, then a proper LCD monitor is a better choice for you. This isn't a critique of the Corsair Xeneon 27QHD240 OLED; every OLED monitor suffers from the same issue.

On the other hand, if you're looking to get an outstanding monitor for gaming, then this could very well be the one. Gaming on a 240 Hz OLED panel, with its rapid pixel response times, low input lag, rich colors, and inky blacks, is a sight to behold. It took me days to adjust back to my IPS monitor after I was done testing the Corsair Xeneon 27QHD240 OLED. I'm permanently spoiled by its SDR and HDR gaming performance, and if you're coming from an LCD, you will be too.
