AOC AG251FZ with 240Hz TN panel


Having recently reviewed the 180Hz-capable ASUS PG248Q, we certainly appreciate that there is some benefit to be had even beyond already high refresh rates such as 144Hz. But with that model, a 144Hz panel is used and then overclocked to up to 180Hz – bringing with it some contrast and artifacting issues. The AOC AG251FZ features a 24.5” TN panel with native 240Hz refresh rate – no overclocking required. The aesthetics of this model are shared with others in the AGON line-up, such as the AG241QX and AG271QG. This includes a fully adjustable stand with solid powder-coated metal base and neck. And a fairly smart design that’s free from divisive design decisions such as obvious flashes of colour. The OSD (On Screen Display) controls are pressable buttons, facing downwards on the bottom bezel near the right side of the screen. A ‘QuickSwitch’ OSD remote is also included, which connects to the monitor via MiniUSB.

The panel used is a 24.5” TN (Twisted Nematic) part with 1920 x 1080 (Full HD) resolution, 170/160° viewing angles, 1000:1 static contrast and a native 240Hz refresh rate. A matte anti-glare screen surface is employed (how light or ‘ungrainy’ this is, is currently unknown). AMD FreeSync is supported (via DP Adaptive-Sync on the monitor) on compatible GPUs to combat tearing and stuttering, with a 48 – 240Hz variable refresh rate range. A flicker-free WLED backlight is used, providing 400 cd/m² typical maximum brightness and offering good sRGB colour space coverage. In addition to the PWM-free backlight, which should enhance viewing comfort for some users, a ‘Low Blue Light’ setting is included for more relaxing evening viewing. A gamma enhancement featured called ‘Shadow Control’ is also included, to enhance the visibility of enemies etc. in dark areas at the expense of image depth and accuracy. A 1ms grey to grey response time is specified for the monitor.

The included stand attaches with screws via 100 x 100mm VESA – an alternative VESA-compatible stand or mount can be used instead. At the right side of the monitor there is; a retractable headphone hook, 3.5mm microphone jack, 3.5mm headphone jack and 2 USB 3.0 ports (1 with fast-charging). The remaining ports include; AC power input (internal power converter), VGA, HDMI 2.0, DP 1.2a (supports Adaptive-Sync) and 2 further USB 3.0 ports. 3W speakers are also included. Both the HDMI 2.0 and DP 1.2a ports support up to 1920 x 1080 @ 240Hz.
