LG UltraGear 27GX790A (27-Inch QHD WOLED/480Hz/0.03ms/98.5% DCI-P3/True Black 400/Esports-Focused) Review
The UltraGear 27GX790A pairs LG's fourth-generation WOLED panel with a 480Hz refresh rate at QHD resolution, positioning it among the fastest OLED monitors available and aimed squarely at competitive esports players who value OLED clarity over 4K resolution.
The WOLED panel delivers approximately 98.5% DCI-P3 color coverage and OLED's characteristic near-infinite contrast, with the lower QHD resolution (versus 4K) allowing graphics cards to more easily sustain the panel's extremely high refresh rate. 480Hz with a 0.03ms GtG response time is among the fastest refresh rates available on an OLED panel, delivering exceptional motion clarity for competitive titles where frame rate and responsiveness matter more than pixel density. Against the Alienware AW2726DM also in this catalog, both run QHD OLED panels, but the 27GX790A's 480Hz refresh rate roughly doubles the Alienware's 240Hz, trading some of Alienware's build refinement for raw competitive-gaming speed.
