Why you can trust Tom's Hardware
Viewing Angles
The MAG321CURV delivers off-axis image quality in keeping with other VA panels, flat or curved. Light reduction is around 50% with a green shift when the image is viewed at 45 degrees to the sides. You can expect a similar effect when looking down at the screen, and detail will be harder to resolve due to a reduction in gamma. Viewed head on, this monitor can be shared by two people sitting less than 5 feet away from the screen.
Screen Uniformity
To learn how we measure screen uniformity, click here.
While the MAG321CURV’s overall uniformity score isn’t too far above our 10% benchmark, we could see a slight glow at the top and bottom of the screen. The anti-glare layer is fitted very tightly, which improves sharpness but can cause uniformity issues. The problem is only visible when viewing a 0% black field pattern. Once we increased the light level, there were no issues either with brightness or color uniformity.
Pixel Response and Input Lag
Click here to read up on our pixel response and input lag testing procedures.


The MAG321CURV equals the other 60 Hz screens in the draw test with a 22ms score. This will produce slight motion blur, but with the overdrive on its middle setting, that artifact shouldn’t interrupt gameplay.
Input lag is a tad higher than the others at 71ms total. We don’t recommend this screen for hardcore shooters or fast-paced sports games. For casual play, it’s perfectly fine. Without Adaptive-Sync, there were occasional frame tears, but we didn’t observe any judder or smearing.

Christian began his obsession with tech when he built his first PC in 1991, a 286 running DOS 3.0 at a blazing 12MHz. In 2006, he undertook training from the Imaging Science Foundation in video calibration and testing and thus started a passion for precise imaging that persists to this day. He is also a professional musician with a degree from the New England Conservatory as a classical bassoonist which he used to good effect as a performer with the West Point Army Band from 1987 to 2013.
