Review: LG 27GP950-B UltraGear
The LG 27GP950-B is the best 4K gaming monitor in our 2026 test — 4K resolution at 144 Hz on a Nano IPS panel, with HDMI 2.1 for next-gen console support. It’s the monitor that best bridges console and PC gaming in a single display.
4K at 144 Hz
4K at 144 Hz is the sweet spot for high-end PC gaming in 2026 — games like Cyberpunk 2077, Elden Ring, and Horizon Zero Dawn look genuinely cinematic at 4K, while 144 Hz ensures fluid motion that’s immediately perceptible versus 60 Hz. In competitive titles (CS2, Valorant at 4K), frame rates typically don’t reach 144 fps, but the extra headroom means consistent framing.
Nano IPS Panel Quality
Nano IPS technology offers 98% DCI-P3 color coverage — critical for content creators who edit on the same monitor they game on. Colors are accurate out of the box (Delta E < 2) without professional calibration. The wide color gamut makes HDR content genuinely vibrant rather than flat.
Console Gaming with HDMI 2.1
Two HDMI 2.1 ports deliver the full PS5 and Xbox Series X experience at 4K@120Hz (not 144Hz, which consoles don’t support). PC gamers use DisplayPort 1.4 for the full 4K@144Hz. This flexibility makes the 27GP950-B the best single monitor for mixed console/PC setups.
Verdict
If you have the GPU to drive 4K gaming (RTX 4080/4090 or RX 7900 XTX), the LG 27GP950-B is the monitor to buy. For those gaming at 1440p, the ASUS ROG Swift PG27AQN delivers 360 Hz at a lower price point.
