Our take on the Monitor ASUS ROG Strix XG309CM Gaming 29.5" FullHD IPS 220Hz 1ms,ELMB,110% sRGB,HDR10

The ASUS ROG Strix XG309CM is a 29.5-inch ultrawide gaming monitor with a 2560x1080 IPS panel running at up to 220Hz with a 1ms response time. It adds ELMB blur reduction, 110% sRGB coverage and HDR10 support, plus the usual ROG extras like an onboard tripod socket and USB-C. It suits gamers who want a fast, wide screen for shooters and racing without stepping up to a larger 1440p ultrawide. Its rivals in this class often top out at 200Hz or skip USB-C, so the XG309CM trades resolution for refresh rate and connectivity.

Questions and answers

Is 220Hz worth it over a 144Hz monitor?

Yes for competitive shooters: the jump from 144Hz to 220Hz is noticeable in fast motion. Casual players may find 144Hz enough.

Does the 2560x1080 resolution look sharp?

It is fine for gaming but pixel density is modest at 29.5 inches, so text and fine detail look softer than on a 1440p ultrawide.

Does it work with a laptop over USB-C?

Yes, USB-C lets a compatible laptop send video and data over one cable. Check your laptop's USB-C supports DisplayPort alt mode.

What is ELMB and should I use it?

ELMB is ASUS blur reduction, which strobes the backlight to sharpen moving objects. It helps in fast games but dims the image and cannot run alongside variable refresh.

What is in the box?

Expect the monitor, a stand, power and display cables, and paperwork. Confirm the exact cable bundle with the seller before ordering.

Is HDR10 good on this monitor?

It accepts HDR10 signals but lacks the brightness and dimming for a real HDR experience. Treat it as a bonus, not a reason to buy.
