At 27 inches, 1440p resolution gives a noticeably more detailed picture than Full HD, while the overclocked 255 Hz refresh rate keeps motion smooth even in fast shooters. ELMB Sync reduces blur together with variable refresh rate, and FreeSync Premium and G-SYNC Compatible keep the image free of tearing. DisplayHDR 400 and 97% DCI-P3 coverage add contrast and saturation to HDR games and films.
Players who like a light-coloured desk and want one screen for a PC, a laptop and a console. Over USB-C the image travels on a single cable, and the connected device receives up to 15 W of power at the same time. There are no speakers, but a 3.5 mm headphone jack handles audio. A tripod socket lets you attach a webcam, for example, which is useful for streamers.
