Manufacturer description
The KTC H34S5 is a 34-inch ultrawide curved gaming monitor built around a 3440x1440 WQHD panel with a 180Hz refresh rate and 1500R curvature. The 21:9 aspect ratio gives you roughly a third more horizontal desktop than a standard 16:9 QHD display, which matters whether you are flanking a game window with Discord and a browser or tracking a wide cockpit view in a sim. Color coverage is the standout number here: 123% sRGB and 98% DCI-P3, paired with a 4000:1 contrast ratio that holds shadow detail better than the 1000:1 panels common at this size. HDR and adaptive sync via FreeSync keep motion…

Frequently Asked Questions
Can this monitor actually hit 180Hz at 3440x1440?
Yes, over DisplayPort 1.4, which the H34S5 provides two of. The two HDMI 2.0 ports carry less bandwidth, so use DP for the full 180Hz at native 3440x1440 resolution.
Will a 1500R curve feel too curved for everyday desktop work?
1500R is on the more aggressive end for a 34-inch panel, which deepens gaming immersion but makes straight lines read as slightly bowed in spreadsheets or CAD. Sit closer to the screen to make the curve read naturally.
Is the color accuracy good enough for photo or video editing?
KTC lists 123% sRGB and 98% DCI-P3 coverage, which is wide-gamut territory suitable for content work. The listing does not publish a factory Delta-E figure, so plan on calibrating if you need certified accuracy.
Does it work with an Xbox Series X or PlayStation 5?
It has two HDMI 2.0 inputs, so consoles connect fine. HDMI 2.0 bandwidth limits what console modes can drive at this resolution, so check your console's supported output list before assuming the highest refresh mode.
