Manufacturer description

The LG 27GN950-B UltraGear puts a 27-inch 4K UHD (3840 x 2160) Nano IPS panel in front of you at a 144Hz refresh rate, which is the combination most 4K monitors make you choose between. The 1ms GtG response time runs through VESA DSC, so you get full resolution and full refresh over a single cable instead of trading one for the other. Color coverage is 98% DCI-P3 with VESA DisplayHDR 600 certification and 400 nits typical brightness, which means HDR content and color-critical editing both hold up, not just gameplay. Adaptive sync is covered from both directions: NVIDIA G-SYNC Compatible and…

Frequently Asked Questions

Can this monitor actually run 4K at 144Hz?

Yes. The 27GN950-B is a 3840 x 2160 UHD panel rated at a 144Hz refresh rate, and it uses VESA DSC (Display Stream Compression) to carry full 4K at 144Hz over a single cable.

Does it work with an NVIDIA or an AMD graphics card?

Both. LG lists it as NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro, so variable refresh rate works on either GPU vendor to reduce tearing and stutter.

Is it good enough for color work, not just gaming?

The Nano IPS panel covers 98% DCI-P3 and carries VESA DisplayHDR 600 certification, with 178-degree viewing angles both horizontally and vertically, so it handles color-sensitive editing alongside gaming.

How bright is it, and what is the contrast ratio?

Brightness is rated at 400 nits typical and the contrast ratio is 1000:1, which is standard for an IPS panel. Blacks will not look as deep as on a VA or OLED display.

Can I adjust the stand or mount it on the wall?

The included stand adjusts for tilt, height, and pivot. The monitor also supports wall mounting, though you should confirm the VESA pattern and bracket requirements on the product listing before buying hardware.
