Refurbished 27" QHD gaming monitor

This refurbished AOC Q27G3Z is a 27-inch display built for competitive gaming. It delivers a 2560 x 1440 resolution with a 16:9 aspect ratio on an IPS panel. The 240 Hz refresh rate and 0.5 ms response time target players who need fast motion clarity. G-Sync Compatible support keeps frames smooth with NVIDIA graphics cards.

240 Hz refresh and 0.5 ms response

The 240 Hz refresh rate handles high-frame-rate esports titles with ample headroom for 1440p gaming. A 0.5 ms response time reduces ghosting during rapid camera movement. The panel runs out of headroom when frame rates exceed the refresh ceiling or when HDR content demands higher sustained brightness than the screen can provide.

HDMI 2.0 and DisplayPort 1.4 limits

HDMI 2.0 caps 1440p output at 144 Hz, so the full 240 Hz requires DisplayPort 1.4. Both inputs support the native resolution, but only DisplayPort unlocks the maximum refresh rate. G-Sync Compatible variable refresh operates within the panel's supported range over the active DisplayPort link.

Questions about this item

Will this 27" 240Hz QHD monitor work with my older graphics card that only has HDMI 2.0?

Yes, the HDMI 2.0 port supports the 2560 x 1440 resolution, though the full 240Hz refresh rate requires the DisplayPort 1.4 connection.

How can I verify the 0.50 ms response time and 240Hz refresh rate are active after setup?

Enable the on-screen display information panel to confirm the current refresh rate, then select the Low Input Lag mode in the OSD to activate the fastest response path.

Does the box include both an HDMI 2.0 cable and a DisplayPort 1.4 cable for the 240Hz signal?

The monitor ships with the stand, power cable and VESA mounting hardware; a DisplayPort 1.4 cable must be purchased separately to reach 240Hz at QHD.
