This is Dell's gaming brand doing a straightforward 27-inch gaming monitor without gimmicks. It's 1440p, which means sharper than 1080p but your graphics card doesn't have to work as hard as it would pushing 4K. The screen refreshes 180 times per second, so motion stays smooth in fast games, and pixels switch fast enough that you won't see blurry trails.
What sets this apart from the usual gaming monitor is DisplayHDR 600, which means it can actually get bright enough to make HDR content pop a bit — not OLED-level dramatic, but better than the fake HDR stickers you see on cheaper screens. Games and shows with HDR will show brighter highlights and deeper shadows than a regular monitor.
The ports include two DisplayPort and one HDMI, plus a USB hub so you can plug peripherals into the monitor instead of reaching behind your PC tower.
