34-inch 240Hz OLED curved gaming monitor

This 34-inch UltraGear OLED display combines a 3440 x 1440 WQHD resolution with a 240Hz refresh rate and 0.03ms response time. The 800R curvature wraps the 21:9 panel around the viewer for immersive play. Built-in webOS provides direct access to streaming apps and cloud gaming services without a PC.

Who this suits and who should look elsewhere

Competitive gamers who need maximum motion clarity and HDR impact at 240Hz will benefit from the OLED speed and 1,500,000:1 contrast. Users requiring sustained full-screen brightness above 275 cd/m² or those who prefer a flat panel for productivity tasks should consider other options.

The spec that decides fit

The 800R curve radius defines the viewing experience; it delivers deep immersion for gaming but can distort straight lines in desktop work. If the curve matches your use case, the 240Hz OLED panel, FreeSync Premium and G-Sync Compatible support, and webOS smart platform complete the package.

Soalan tentang produk ini

Which video outputs on my graphics card will drive the 34GX90SA-W at its full 240 Hz and 3440 x 1440 resolution?

Use the DisplayPort 1.4 or HDMI 2.1 ports on your GPU; both carry the bandwidth needed for the panel's 240 Hz refresh rate and WQHD resolution.

Will my older GPU that only supports FreeSync still benefit from the monitor's adaptive sync range?

Yes — the display is FreeSync Premium certified and G-Sync Compatible, so any GPU with FreeSync support will deliver tear-free gaming across the full variable refresh range.

How can I confirm the monitor is actually running at 240 Hz and HDR after I connect it?

Open the on-screen display information menu; it shows the current refresh rate and HDR status, and Windows display settings will list 240 Hz as the active mode.
