Dell	26.5-inch (27-inch class) OLED, 16:9 The actual viewable diagonal is 26.5 inches. LG
Refresh rate and response time	120 Hz (48–120 Hz vertical frequency); 4 ms GtG (Extreme), 5 ms GtG (Fast), 8 ms GtG (Normal); AMD FreeSync Premium 120 Hz at 4K is available over both HDMI 2.1 and DisplayPort 1.4; the source must also output 4K at 120 Hz. FreeSync Premium matches the refresh to the game’s frame rate within 48–120 Hz to prevent tearing; AMD’s tier also includes low framerate compensation (LFC). GtG figures are given for the fastest overdrive mode. Dell	—
Brightness, contrast and colour	300 nits; 3000:1 contrast; 1.07 billion colours; 95% DCI-P3, 99% sRGB; HDR10 HDR10 support means the monitor accepts HDR signals; with 300 nits and edge lighting it carries no DisplayHDR tier. 1.07 billion colours corresponds to 10-bit colour depth. Dell	—
Connections	2 × HDMI 2.1 (FRL, HDR, VRR; up to 4K 120 Hz; HDCP 2.2), 1 × DisplayPort 1.4 (4K 120 Hz, HDR, VRR; HDCP 2.2) There is no USB-C, USB hub, headphone output or webcam, so a laptop cannot be charged over a single cable. A 1.8 m HDMI cable is in the box. Dell	—

Resolution and pixel pitch	—	2560 × 1440 (QHD); 0.2292 mm pixel pitch QHD at 27 inches means lower pixel density than 4K; small text looks less crisp but high frame rates are easier to reach on the GPU. LG
Refresh rate	—	480 Hz 480 Hz means up to 480 frames per second; seeing that benefit requires the game and GPU to deliver close to 480 fps. LG
Response time	—	0.03 ms (GtG) Grey-to-grey pixel transition time; it is not input lag. LG
