I’ve accumulated quite a few 32-inch 4K monitors in my test database. To compare the G3223Q, I’ve included MSI’s MPG321UR-QDX, BenQ’s EX3210U, Philips 320M1RV and Asus’ PG32UQ. To represent Mini LED, I’ve also put in the ViewSonic XG321UG. It is quite a bit more expensive than the rest, but it also delivers unparalleled contrast and brightness for HDR content.
Pixel Response and Input Lag

The MSI continues to be the only 4K 144 Hz monitor I’ve tested that has a measurably quicker response time than its competitors. 6ms versus 7ms is a subtly visible difference in rapid movement sequences. Quick camera pans and flying objects are a bit clearer and have greater motion resolution.
The G3223Q shines in the overall lag test. I didn’t need any special settings to achieve 30ms of total control lag, which is the quickest score I’ve recorded for any 144 Hz screen, regardless of resolution. The only way to get less lag and more smoothness is with a higher refresh rate. And, of course, a higher frame rate. QHD 240 Hz screens are the kings of balanced performance right now, but UHD 240 Hz is allegedly just around the corner.
The G3223Q has decent viewing angles from a brightness perspective. You can see that there is barely any reduction in light output as the view shifts to 45 degrees off-axis. The color goes slightly green, which is a typical trait for IPS monitors. The top view is blue in tone with a 40% light reduction and washed-out detail. This is also typical IPS performance. The G3223Q can be comfortably shared by two users.

My G3223Q sample had decent black field uniformity, with the meter detecting a hot spot in the upper-right corner. I could not see this error in actual content, nor could I see any color aberrations or other anomalies in any material, regardless of overall brightness level.
