27-inch 5K 180 Hz IPS gaming monitor

The SAMSUNG Odyssey LS27HG802EFXZA delivers a 27-inch flat IPS panel at 5120 x 2880 resolution with a maximum 180 Hz refresh rate. It covers 99 % of the sRGB gamut, reaches 350 cd/m² brightness, and supports HDR10+ for richer highlights. Adaptive sync works with both FreeSync Premium and G-Sync Compatible graphics cards.

Competitive gamers and creators needing dual-mode

The monitor switches between 5K at 180 Hz and QHD at 360 Hz, giving esports players a high-refresh fallback without changing hardware. Users who require higher contrast than 1,000:1 or a curved screen should consider other models. The stand provides height, pivot, swivel and tilt adjustments for ergonomic setups.

Dual DisplayPort 2.1 and HDMI 2.1 inputs

One DisplayPort 2.1 port, one USB-C port with DisplayPort Alternate Mode and two HDMI 2.1 ports drive the high resolutions and refresh rates. Two USB 3.2 Gen1 Type-A ports and one USB-B upstream port handle peripherals. VESA 100 x 100 mm mounting is supported for wall or arm installations.

Questions about this item

How do I attach the stand to the 27" Odyssey monitor, and which step is often missed?

Align the stand neck with the rear mounting bracket, push until it clicks, then tighten the captive thumb screw; the step people skip is fully tightening that screw, which leaves the stand wobbly.

What maintenance will the IPS panel and USB 3.2 Gen1 hub need over time?

Clean the anti-glare coating with a microfibre cloth and distilled water only; vacuum the USB-A ports annually to prevent dust buildup that can interrupt 5 Gbps data rates.

At 5K 180 Hz over DisplayPort 2.1, what limit appears first during long sessions?

The 350 cd/m² peak brightness and 78 W power draw mean the panel hits its thermal ceiling before the 1 ms response time or 1,000:1 contrast ratio degrade.
