AOC 24G51F2 - Budget 180Hz Full HD Gaming Monitor

Our analysis

At the other end of our monitor list, the MSI MAG 271QPX runs 27-inch QHD on QD-OLED at 360 Hz; the AOC 24G51F2 runs 23.8-inch Full HD on IPS at 180 Hz, with a 0.5 ms (MPRT) response time. Full HD at 180 Hz is the point: it asks far less of a graphics card than QHD at 360, so an entry GPU can actually reach the refresh rate. It suits esports players, entry-level graphics cards and anyone who would rather put the money into the GPU than into the monitor.

What stands out

• 180 Hz that a modest card can actually use. 1080p is the lightest resolution for a graphics card and esports shooters are light games, so even an entry GPU can push frame rates near the refresh rate.
• IPS panel. IPS keeps colors consistent at wide viewing angles, unlike a TN panel.
• Adaptive-Sync, DisplayPort 1.4 and HDMI 2.0. Adaptive-Sync matches the refresh to your frame rate to avoid tearing, and two inputs let a second device stay plugged in.
• The right size for tight desks, with VESA. 24 inches suits a narrow desk, and the VESA mount lets you hang it on an arm later to free the surface.

Where it falls short

• Resolution tops out at Full HD and HDR is entry-level (it is listed as HDR Ready), so do not expect OLED blacks.
• It is a fast entry-level monitor rather than a showcase for picture quality.

Look elsewhere if

• You have a mid-to-high GPU and want a big jump in image quality: the LG UltraGear 27GX704A gives you 27-inch QHD OLED at 240 Hz. For a balanced 1440p step, the MSI MAG 274QP QD-OLED offers WQHD at 240 Hz with height adjustment; like any OLED, avoid it if the screen shows static work windows all day.
