The comparison group is all FHD screens ranging in size from 24 to 32 inches. The S2422HG and its stablemate S3222HG are VA panels, while the Gigabyte G27F2, Monoprice 42771, Viotek GFI24CBA and BenQ EX2510S are IPS. Refresh rates run from 144 to 170 Hz.

While 165 or 170 Hz offers a slight advantage over 144 Hz, the difference in motion resolution is subtle. The S2422HG matches the lone 144 Hz screen here at 7ms for a full screen draw. I found it was a little hampered by a weak overdrive which showed thin black trails behind moving objects in test patterns. This is a symptom of undershoot. Dell could improve this monitor with a more aggressive option. MPRT (backlight strobe) removes the black outline but adds in a phasing artifact that I see in most gaming monitors with the feature. The best picture is when Adaptive-Sync is turned on and Response Time is set to Fastest.
The S2422HG has very low input lag, which makes it a good choice for the twitchier players among us. It proved to be more than enough monitor for my average skills. If you play at a high level, you’ll want to consider something running at 240 Hz or faster. But for $170, this Dell delivers plenty of usable performance.
The viewing angles of VA monitors are never stellar, but the S2422HG does a decent job when seen at 45 degrees off-axis. You can see a red/green tint and a 30% brightness reduction, but detail is still clearly rendered throughout the image’s luminance range. The top view is very washed out with a green tint. Sharing is probably not the best use for any 24-inch monitor. However, it’s fine for a single user with no shifts in image quality when viewed from two to four feet away.

My S2422HG sample had excellent screen uniformity except for the lower-right corner zone, which was a tad brighter than the rest. This did not affect gaming content, and you won’t see the anomaly in anything but the darkest material, which is good performance for the price.
