About the LG UltraGear 27GX704A-B

The UltraGear 27GX704A-B is the OLED monitor we pick for a gaming desk that also gets used at night. Each pixel lights itself, so blacks are truly black, and LG rates the response time at 0.03 ms (GtG). At 2560 x 1440 and 240 Hz, a mid-range graphics card can keep it busy without needing a 4K-class GPU.

The panel is glossy, which makes colours pop but shows reflections in a bright room. You get two HDMI 2.1 ports for consoles, one DisplayPort 1.4 for the PC, a small USB hub and a stand that adjusts in height, tilt, swivel and pivot. The real diagonal is 26.5 inches.

Why it is here

The 1440p OLED panel runs at 240 Hz with a 0.03 ms response time, a level the RTX 5070 in the OMEN can actually feed. Its stand adjusts in height and pivot, so the screen reaches eye level without an arm.
