Curved 34" VA panel for high-refresh gaming

This 34-inch curved VA monitor delivers a 3440 x 1440 resolution at a 240Hz refresh rate with 1ms response time. AMD FreeSync Premium adaptive sync reduces tearing during fast motion. The 1500R curvature wraps the 21:9 ultra-wide view around the user for immersive play.

Height and tilt stand plus dual HDMI 2.1

The included stand provides height and tilt adjustment so the screen can be centred at eye level. Two HDMI 2.1 ports and one DisplayPort 1.4 connection support current consoles and graphics cards at full bandwidth. Built-in 2W stereo speakers handle basic audio without external hardware.

Check 100 x 100mm VESA and 65W power draw

Verify that your monitor arm or wall mount uses the 100 x 100mm VESA pattern before ordering. The unit draws 65W from a 100-240VAC supply, so confirm your power strip or UPS has an available outlet. Ensure your graphics hardware can drive 3440 x 1440 at 240Hz over DisplayPort 1.4 or HDMI 2.1.

Questions about this item

Will the 65 W power supply need replacement after a few years of daily use?

The internal 100–240 VAC supply is rated for 65 W typical draw; no user-serviceable parts are inside, so replacement is only needed if the unit itself fails.

What limits the 240 Hz refresh rate during long gaming sessions?

The 1 ms VA response time and 250 nit brightness ceiling are the first constraints; sustained 240 Hz output holds as long as the panel stays within thermal limits.

How loud or hot does the monitor get when running at 240 Hz all day?

No fan is present, so audible noise is negligible; the 65 W draw warms the chassis to a mild level, and the anti-glare VA surface stays comfortable for extended use.
