Uncalibrated – Maximum Backlight Level

The S3222DGM and S2722DGM are alike in styling and specs, but the similarities pretty much end after the maximum brightness test. Both screens are mid-pack with an output of over 350 nits. This is plenty of light and far more than you’ll need indoors, especially from a 32-inch monitor.

The gap starts to open up in the black level test. The S3222DGM has a lower score than its stablemate and it’s lower than the other monitors too. 0.0837 nit is really dark. That puts the max contrast ratio over 4,200:1, which is one of the highest values in my database. It’s rare that a computer monitor can muster that kind of dynamic range.

After Calibration to 200 nits

After calibration, the S3222DGM stays in the lead for both black levels and contrast by comfortable margins. This is one contrasty monitor, and you can easily see the difference in content. You won’t miss HDR one bit. And its larger color gamut is on full display with vivid saturation and depth.

The ANSI result is a bit lower but still high enough to lead the pack and one of the highest-scoring monitors in this test. One might consider the 27-inch version for its greater pixel density, but I would choose the 32-inch based on its greater contrast.

    One minor correction:

    A joystick handles most of the navigation duties along with four control keys. Two of them can be programmed by the user.

    Actually 3 of the buttons can be customized.

    You guys just missed the 300 USD discounted price at, but it will probably see a discount again.

    I still havent seen any applications that really do HDR well, pretty much has been off the entire time Ive had my monitor. Except for maybe media content but that’s what my tv is for.

    How does this one compare to the s3220dgf?

    32" seems too big for FPS gaming. If I lower the resolution for games to Full HD, can the display show smaller image with black borders? That would make playing games comfortable and I could still use 32" for office work. Thanks!
