ViewSonic XG2401 24-inch FreeSync Monitor Review

ViewSonic is the latest major display manufacturer to add FreeSync to its lineup. Today, we're testing the 24-inch XG2401. It's a FHD/TN screen with a 144Hz refresh rate and ultra-fast panel response.

Brightness And Contrast

To read about our monitor tests in-depth, please check out Display Testing Explained: How We Test Monitors and TVs.  Brightness and Contrast testing is covered on page two.

Uncalibrated – Maximum Backlight Level

FreeSync is the least expensive way to add adaptive refresh to your gaming rig. To that end we've collected data from five other TN-based monitors that sell in the $275 to $500 range. The Asus MG278Q, Acer XG270HU and BenQ XL2730Z are QHD while the XG2401, Nixeus NX-VUE24A and AOC G2770PF are FHD. The higher pixel count typically adds about $200 to the price.

The XG2401 has light output to spare with brightness over 400cd/m2. While most of us would burn our retinas at this level indoors, it's helpful when you have to compete with incoming sunlight.

The max black level only drops to third place, which means this monitor has pretty high contrast compared to other TN and IPS panels.

This is one of the highest contrast results we've measured from a non-VA screen. We realize the product's main draw is its 144Hz refresh rate and FreeSync operation. But image depth is still important and the XG2401 has plenty of that.

Uncalibrated – Minimum Backlight Level

The backlight goes a little low for our taste. Raising the slider to four will give you a more palatable 50cd/m2.

The Nixeus wins this contest thanks to its super-low backlight setting. The ViewSonic's black levels continue to impress, however, with a second-place finish.

Minimum contrast remains above 1200:1, which is excellent performance. TN may not be everyone's favorite technology but the latest panels offer great image quality and the XG's 24-inch size mitigates most of our viewing angle concerns.

After Calibration to 200cd/m2

After calibration, we see an even lower black level than before. It helps that we are able to increase the contrast slider; something we almost never do. And full detail is retained at both the shadow and highlight ends of the scale.

The final calibrated contrast result is one of the best we've recorded from a TN or IPS display. When viewed straight-on, you won't be able to tell which technology is in use. ViewSonic's choice of TN has kept speeds high and the price reasonable without any sacrifices in image fidelity.

ANSI Contrast Ratio

Thanks to some of the best panel uniformity we've seen lately, the XG2401 lays down an impressive ANSI test result. Very few panels of any type can match their sequential numbers so closely. The part in use here is obviously of high quality.

    1st lol. On the serious note, is the panel native 8-bit one? That contrast ratio looks too good to be true .....

    48hz isn't optimal but it sure as hell is still damn good. 20hz would be perfect.

    freesync is kicking ASS. i hope nvidia continues to rest on their laurels as AMD picks up more market share and becomes a more formidable competitor.

    CONS: 48Hz lower FreeSync --> Christian, didn't you hear about Low Framerate Compensation?
    144 > 2,5x48 --> meaning LFC is on so the actual FreeSync range is 0-144Hz

    Great contrast. Definitely a plus for gaming. If you have the goods to keep framerates above 48 consistently, this monitor looks like a catch.

    Christian, could you confirm screen part number ( is it real 8-bit one or 6-bit+dithering ) please.

    Another low price monitor good for a low range gaming rig. Not my cup of tea, but cool that the market isn't abandoning the cheaper options for peeps that don't run the latest, greatest parts in their rigs.

    Not sure why people diss the "low price monitor", but Freesync and Gsync needs to encompass a larger range of price point. Faster value adoption means paying less "premium" for Freesync/Gsnyc in the top range. Otherwise, adaptive sync would be niche tech that would die in a year and two, and the so-called "premium feature" would no longer be supported.
