Frequently Asked Questions

Can I actually hit 320Hz on this monitor?

You need DisplayPort 1.4 for the full 320Hz refresh rate; the two HDMI 2.0 ports carry less bandwidth and will cap lower. A DP cable and a GPU capable of pushing 300+ FPS at 1080p are both required.

Does the KOORUI G2511E work with a PS5 or Xbox Series X?

Yes, through either of the two HDMI 2.0 ports. Note that HDMI 2.0 does not carry the full 320Hz signal, so consoles run at their standard output modes rather than the panel's maximum refresh rate.

Is the panel IPS or TN?

It is a Fast IPS panel with 95% DCI-P3 color gamut coverage and HDR 400 support, so you get wide viewing angles and stable color off-axis alongside the 1ms GTG response time.

Can I mount this on a monitor arm?

Yes. The G2511E supports VESA 75x75mm mounting for desk arms or wall mounts. The included stand also offers tilt, height, and vertical adjustment if you would rather not use an arm.

What warranty does KOORUI provide?

KOORUI backs the display screen for 1 year and other accessories for 3 years. Check the current product listing for full terms and regional coverage before purchasing.
