The best LG gaming monitor with a 1080p resolution that we've tested is the LG 27GN750-B. That said, if you're looking for something with a 4k resolution, the 27GN950-B is one of the best LG monitors we've tested. It performs well in bright rooms thanks to the impressive peak brightness, but the reflection handling is disappointing. If you don't mind spending more money on a 4k display, the LG 48 CX OLED TV is also marketed as a monitor and supports 4k 120Hz over HDMI, which is great if you own a PS5 or Xbox Series X. There's an edge-lit local dimming feature, but it performs terribly and can be quite distracting. HDR content looks good because it displays a wide color gamut and gets fairly bright in HDR to make some highlights pop. Unfortunately, because it has an IPS panel, blacks look closer to gray. The response time is exceptionally quick whether you're playing at 144Hz or 60Hz, so fast-moving content looks smooth. Input lag is incredibly low, and even though it slightly increases with VRR enabled, most people shouldn't notice any difference. It has a high 160Hz refresh rate, but you can only achieve that refresh rate over a DisplayPort connection and with a graphics card that supports Display Stream Compression. This model has native FreeSync support, and it's compatible with NVIDIA's G-SYNC as well. It's one of their first 4k gaming models, although they've produced office monitors at this resolution, like the LG 27UK650-W. The best LG monitor that we've tested with a 4k resolution is the LG 27GN950-B.
