27-inch 320Hz QHD gaming monitor

This 27-inch IPS panel delivers a 2560 x 1440 resolution at a 320Hz refresh rate with a 0.5ms response time. AMD FreeSync Premium provides variable refresh support for tear-free gameplay. The anti-glare screen covers 99% of the sRGB colour space and outputs 1.07 billion colours at 250 cd/m² brightness.

Competitive players wanting speed

Fast-paced shooters and esports titles benefit from the high refresh rate and low pixel response. The wide 178° viewing angles keep colours consistent from different positions. Users needing higher peak brightness for HDR highlights or a curved ultrawide format should consider other models.

320Hz refresh with QHD resolution headroom

The panel comfortably handles high-frame-rate 1440p gaming through its DisplayPort 1.4 and two HDMI 2.1 ports. The 0.5ms response reduces motion blur in rapid scenes. Brightness tops out at 250 nits, so HDR content shows limited dynamic range compared to brighter displays.

Questions about this item

What graphics card port do I need to reach the 320Hz refresh rate at 2560 x 1440?

A DisplayPort 1.4 connection or an HDMI 2.1 port on your GPU is required to drive the full 320Hz at QHD resolution.

Will my older GPU limited to HDMI 2.0 still work with this monitor?

Yes, the two HDMI 2.1 ports are backward compatible, though the maximum refresh rate at 2560 x 1440 will drop to the HDMI 2.0 limit.

How can I confirm the panel is actually running at 320Hz after I connect it?

Open the on-screen display menu and check the information page; it will show the current input timing as 2560 x 1440 at 320Hz when the link is correct.
