Our take on the LG UltraGear 27GN800-B 27-inch

The LG UltraGear 27GN800-B is a 27-inch 1440p gaming monitor built on an IPS panel with a 1 ms response time and 10-bit color. It is a plain, fast, color-accurate screen: no curve, no RGB, no built-in camera or speakers. Its rivals at this size are mostly VA panels with deeper blacks but slower pixel response, or 1080p IPS screens that look softer. It suits gamers who want sharp 1440p detail and wide viewing angles, and buyers who will mount it or accept a basic tilt stand.

Questions and answers

Is the LG 27GN800-B good for competitive gaming?
Yes. It has a 1 ms response time, low input lag and a fast IPS panel, which suits shooters and other fast games. It lacks the highest refresh rates of premium esports monitors, but it is quick enough for most players.
Does it have built-in speakers?
No. There are no speakers, but there is a headphone out and an audio line out for connecting speakers or a headset.
Can I mount it on an arm?
Yes. It has a VESA mount, and the stand is removable. Many owners use an arm because the stock stand only tilts.
Is it worth choosing over a 1080p 240 Hz monitor?
If you want sharper detail and better colors for mixed use, the 1440p IPS panel is the stronger pick. A 1080p high-refresh screen is better only for players who prioritize maximum frame rate above resolution.
Does it support HDR?
It accepts an HDR signal, but the panel's contrast and brightness are too limited for a meaningful HDR experience. Treat it as an SDR monitor.
What is in the box?
The monitor, its tilt stand, a power cable and a DisplayPort cable. Check which cables a given listing includes before buying.
