34" 21:9 curved gaming monitor

The HKC CG345UK is a 34-inch ultra-wide VA panel with a 1500R curve and 3440 x 1440 resolution. It targets gamers and creative users who want expansive 21:9 visuals, 240Hz motion clarity and 95% DCI-P3 colour coverage in a single display. The stand provides height, tilt, swivel and pivot adjustment plus 75 x 75 mm VESA mounting.

HDMI 2.1 and DisplayPort 1.4 bandwidth limits

Two HDMI 2.1 ports and one DisplayPort 1.4 connection drive the panel. At the native 3440 x 1440 resolution the 240Hz refresh rate is supported over both interfaces, but HDR400 metadata and 10-bit colour at that rate rely on the source device and cable quality. Console variable-refresh-rate features depend on the HDMI 2.1 implementation in the host.

1 ms DIC response time

The monitor specifies a 1 ms DIC response time paired with the 240Hz refresh rate. This figure determines how cleanly fast motion renders in competitive titles; if your priority is the lowest possible ghosting at 3440 x 1440, this spec is the deciding factor.

Questions about this item

Will my graphics card need DisplayPort 1.4 or HDMI 2.1 to reach the full 240 Hz at 3440 x 1440?

Yes — the monitor provides one DisplayPort 1.4 and two HDMI 2.1 ports; use either standard with a compatible GPU to drive the native resolution at 240 Hz.

Does the stand let me centre the screen at eye level without a separate riser?

The stand adjusts 110 mm in height, tilts -5° to 20°, swivels ±30° and pivots ±30°, so most users can set a comfortable viewing height directly.

What cables are in the box so I can connect it immediately?

A 1.5 m DisplayPort cable, a 1.2 m adapter cable and a 1.5 m power cable are included.
