5K2K OLED 45″ ultra-wide monitor

This 45-inch curved OLED panel delivers a 5120 x 2160 resolution at 165 Hz. A 125 PPI layout reduces color fringing for sharp text. DCI-P3 98.5% coverage and 1300 cd/m² peak brightness produce deep blacks and vivid highlights. DisplayHDR True Black 400 certification confirms HDR performance.

Suits immersive sim and productivity users.

The 21:9 aspect ratio and 5K2K pixel count benefit expansive game worlds, content creation and multi-window workflows. Competitive players focused on maximum frame rates may prefer a smaller, higher-refresh panel. Dual-mode switching adds flexibility for different genres.

Dual-mode 165 Hz 5K or 330 Hz FHD

A hotkey toggles between native 5120 x 2160 at 165 Hz and wide Full HD at 330 Hz. This single specification decides whether the monitor matches your GPU output and game-type priorities. Adaptive sync works across both modes via FreeSync Premium Pro and G-Sync compatibility.

Questions about this item

Will my graphics card need DisplayPort 2.1 to run the 5K2K resolution at 165 Hz?

The monitor supports DisplayPort 2.1 bandwidth for that mode, so a GPU with DisplayPort 2.1 is required to achieve 5120 x 2160 at 165 Hz.

Does the Dual Mode switch require a driver or can I toggle it from the monitor itself?

A dedicated hotkey on the monitor lets you change between 5K2K at 165 Hz and Wide Full HD at 330 Hz without any software.

Is the stand adjustable enough for a deep desk and a low sitting position?

The included stand provides height adjustment, swivel and tilt so you can set the 45-inch curve at a comfortable viewing angle.
