27-inch UltraGear Dual Mode Monitor

The LG UltraGear 27G810A-B is a 27-inch IPS gaming monitor with a native 4K UHD resolution of 3840 x 2160. Its Dual Mode feature allows switching between 4K at 180Hz and Full HD at 360Hz via a hotkey. A 1ms GtG response time reduces motion blur. It covers 95% DCI-P3 and supports VESA DisplayHDR 400.

Competitive Gamers and Creative Users

This monitor suits players who want high-resolution detail for story titles and high refresh rates for competitive shooters. The 178-degree viewing angles and 1.07 billion colours benefit content creators needing colour accuracy. Users requiring higher contrast ratios or true 10-bit panels should evaluate alternatives.

Dual Mode Resolution and Refresh Switching

The defining specification is the Dual Mode capability offering 4K UHD at 180Hz or Full HD at 360Hz on a single 27-inch panel. This hardware-level switching lets you prioritise pixel density or motion clarity per game genre. Verify your graphics card supports DisplayPort 1.4 bandwidth for the 4K 180Hz signal.

Questions about this item

Will my graphics card need a specific port to run the 4K 180Hz mode?

The monitor provides one DisplayPort 1.4 and two HDMI ports. Use DisplayPort 1.4 with a compatible GPU to achieve 4K at 180Hz.

Can I use the USB ports to connect a keyboard and mouse directly?

Yes. The upstream USB 3.0 link connects to your PC, and the two downstream Type-A ports then power peripherals such as a keyboard and mouse.

How does the Dual Mode switch between 4K and Full HD affect the image?

Press the dedicated hotkey to toggle: 4K UHD at 180Hz for detail-rich games, or Full HD at 360Hz for maximum motion clarity in competitive titles.
