40" 21:9 WQHD gaming monitor

The Z-EDGE UG40S is a 40 inch ultrawide IPS display with a 3440 x 1440 resolution and 144 Hz refresh rate. It targets gamers and multitaskers who want a wide field of view without a curved panel. The 1 ms MPRT response time and FreeSync support keep motion sharp in fast titles. Wide 178 degree viewing angles preserve colour consistency across the large screen.

Installation notes

The monitor connects through two HDMI 2.1 ports, one DisplayPort 1.4 and one USB-C port that carries power only. The stand provides 95 mm height adjustment, -5 to +15 degree tilt and -15 to +15 degree swivel for ergonomic positioning. A 100 x 100 mm VESA pattern allows wall or arm mounting if the stand is removed. Built-in 2 W speakers handle basic audio without extra cables.

Sustained-load behaviour

Typical power draw is 65 W from a 100-240 V supply, so heat output stays modest during long sessions. The IPS panel maintains 350 cd/m2 brightness and 1200:1 contrast without the drift sometimes seen on VA alternatives. Adaptive-Sync and HDR10 remain active continuously, preventing tearing and preserving dynamic range over extended play. The flat 21:9 surface avoids the uniformity shifts that curved ultrawides can develop when warm.

Questions about this item

How can I confirm the UG40S is running at its full 144 Hz refresh rate after connecting it?

Open the on-screen display or your GPU control panel and verify the active timing reads 3440 x 1440 at 144 Hz; this maximum rate is only available through the DisplayPort 1.4 input, while HDMI 2.1 caps at 100 Hz.

Which cables and accessories ship with the UG40S and what must I provide myself?

The box contains the monitor, an ergonomic stand with height, tilt and swivel adjustment, a power cord for 100-240 VAC, and at least one video cable (typically DisplayPort or HDMI); a VESA 100 x 100 mm mount and any extra HDMI or USB-C cables are not included.

The UG40S appears as a single 40" 21:9 WQHD model — are there different versions or capacities to choose from?

No, the UG40S is offered in one configuration: a flat 40-inch IPS panel with 3440 x 1440 resolution, 144 Hz via DP 1.4, FreeSync, HDR10, 350 cd/m² brightness, 65 W typical power draw, and built-in 2 W x 4 speakers.
