The Samsung C34J791 34 inch Monitor envelops your field of vision like an iMax cinema screen.

Packed with features to satisfy the most dedicated gamers, this premium curved monitor boasts a 100hz screen refresh rate for minimal stutter, a 4ms response time for blur-free action scenes, and AMD Freesync for silky smooth gameplay.

Game Mode also lets you instantly optimise screen brightness and contrast ratios, you’ll also enjoy spotting your enemies faster in any kind of game.

Ultra WQHD enables a screen resolution of 3440x1440 - 2.5 times the pixel density of Full HD - that delivers razor-sharp images. The greater pixel density also creates a wider screen workspace, so you see more content at once without having to scroll and zoom excessively when surfing the web or viewing large files.

Forget about the inconvenience of dual monitors - with the 21:9 ultra-wide screen you can experience truly seamless multitasking on a single monitor. The Picture-by-Picture (PBP) function lets you connect 2 input sources using HDMI and DP while maintaining the original image quality. You can also resize the second image to cover up to 25% of the screen and position it anywhere.

Supporting up to 125% sRGB colour space, Quantum Dot technology delivers not only more colours than conventional monitors, but colours that are brighter, crisper, and more natural.

The 34 inch ultra-wide curved monitor gives you an immersive widescreen viewing experience like no other monitor. Flicker Free technology and Eye Saver Mode also reduce fatigue-inducing blue light emissions.
