27-inch IPS gaming monitor

The Acer Nitro KG273 W3BIIP is a 27-inch flat panel built for competitive play. Its IPS panel delivers 178-degree viewing angles and 16.7 million colours. A 240 Hz refresh rate pairs with a 0.50 ms response time. AMD FreeSync Premium provides adaptive synchronisation.

Full HD resolution and 240 Hz headroom

The 1920 x 1080 resolution keeps pixel counts low so modern GPUs can sustain high frame rates. At 250 nits brightness and a 100,000,000:1 contrast ratio the image stays readable in typical indoor light. Demanding HDR titles will run into the limited peak brightness and lack of local dimming.

DisplayPort 1.2 and HDMI 2.0 connectivity

One DisplayPort 1.2 and one HDMI 2.0 port carry the 240 Hz signal at 1080p. The stand adjusts for height and tilt, and a 75 x 75 mm VESA mount allows arm or wall installation. The monitor draws 48 W from a 100-240 VAC supply.

Questions about this item

Will the KG273 W3BIIP's 240Hz refresh rate work with my older GPU over the HDMI 2.0 port?

The HDMI 2.0 input supports the full 1920 x 1080 resolution at 240Hz, so an older GPU with HDMI 2.0 can drive the panel at its maximum refresh rate without needing DisplayPort.

How can I verify the 0.50 ms response time and FreeSync Premium are active after I connect the monitor?

Enable FreeSync in the AMD graphics driver control panel and select 240Hz in Windows display settings; the on-screen menu will show the current refresh rate and confirm Adaptive Sync is engaged.

Does the box include a DisplayPort 1.2 cable for the 240Hz connection, or do I need to buy one separately?

The monitor provides one DisplayPort 1.2 and one HDMI 2.0 port; check the packaging list for included cables, but a certified DisplayPort 1.2 cable may need to be purchased separately for the 240Hz link.
