Monitor specialist AOC has launched a pair of new gaming screens into its Agon 5 series. There are two new 27-inch models featuring flat 1440p screens and attractive specs such as 240 Hz refresh rates, 1 ms GtG and 0.5 ms MPRT response times. However, one is based on a QD-IPS display panel, and the other more affordable model uses a VA panel.

AOC’s new Agon AG275QZ/EU is the higher-end model among the new pair. Its fast IPS screen features a quantum dot layer for 1.07 billion colors, and HDR400 support. It has a standard 240Hz refresh rate, but can be overclocked to 270 Hz. Some other performance niceties include the screen’s response time of 1 ms GtG and 0.5 ms MPRT. These performance features facilitate fluid visuals with minimal ghosting or motion blur. Both FreeSync Premium and G-SYNC Compatible are supported, free-slowing and tear-free gaming visuals.

Turning our attention to the new AOC Agon AG275QZN/EU, a lot of the great features mentioned above are carried through. This model is built around a VA panel with the same resolution and headlining performance stats. It isn’t overclockable, or such a feature isn’t mentioned, but the max 240 Hz refresh is very respectable. It keeps up with the IPS version in terms of response times though, with 1 ms GtG and 0.5 ms MPRT. This screen supports AMD FreeSync Premium, but no mention of G-SYNC is made. It is also HDR400 certified, but the display is limited to 16.7 million colors.

To avoid confusion, please refer to the comparison table below to see the where the key specs of the Agon AG275QZ/EU and Agon AG275QZN/EU align and differ.

The two monitors appear to share the same ergonomic stand; with -5/23 degree tilt, -20/20 degree swivel, pivoting functionality, and 150 mm of height adjustment. Users can also use these monitors with standard 100x100 VESA mounts.  As Agon series gaming monitors, these also have multiple gaming modes and presets, G-menu features such as color equalizer settings, motion blur reduction, low input lag, shadow control, crosshairs, frame counters, and more.

AOC says its new Agon 5 monitors will be available this month. We only have Euro prices at this time, with the Agon AG275QZ/EU carrying an MSRP of €819, and the  Agon AG275QZN/EU at €569. Whether the price / performance combinations on offer here will get these monitors into our regularly updated Best Gaming Monitors 2022 feature, remains to be seen.
