About this model
Text from the manufacturer, via Icecat.
The ProLite XCB3494WQSU is a 34-inch curved monitor with a VA panel, delivering high contrast, deep blacks, and wide viewing angles for consistent image quality from any perspective. UWQHD (Ultra-Wide QHD) resolution provides an ultra-wide (21:9) viewable area. The large amount of screen space and good pixel density make it very suitable for those who want to use side-by-side applications, watch widescreen content or enhance their gaming experience. For added comfort and flexibility, the 15cm height-adjustable stand allows you to adjust the screen position to your preference. Additionally, flicker-free technology and a blue light reducer function reduces eye fatigue.
