The ViewSonic XG2402 is a decent TN monitor. It is exceptionally well suited as a gaming monitor, thanks to the high 144 Hz refresh rate and FreeSync VRR support. It has excellent motion handling thanks to the extraordinarily fast response time, and there is almost no motion blur. Unfortunately, it isn't as well suited for a dark room due to the disappointing native contrast and deficient black uniformity, and it has poor viewing angles, so it is best suited for viewing from directly in front.
The ViewSonic XG2402 has a good design. It is almost entirely made of plastic, but it feels well built and is quite solid. The stand isn't the fanciest, but it supports the monitor well and has great ergonomics. Unfortunately, there is not much to help with cable management. The monitor is quite thick, but this shouldn't cause any issues.
Very good ergonomics. The XG2402 is very easy to adjust to an optimal viewing position. Note that the ViewSonic website lists the tilt range as -20° to +5°, but we measured -15° to +5°.
The back of the XG2402 looks decent. It has a slightly stylized design and the red chevrons on the back light up. There is single heat vent out the top of the monitor. Unfortunately, there isn't much in terms of cable management.
The ViewSonic XG2402 has only decent picture quality. It doesn't perform very well in a dark room, due to the disappointing native contrast and deficient black uniformity. It has good peak brightness, and good reflection handling, great for a bright office. It has disappointing viewing angles, so the image is most accurate from directly in front.
Very good peak brightness. There is only slight variation in brightness with content, which is good.
HDR is not supported.
The ViewSonic XG2402 has poor horizontal viewing angles. Uniformity issues are noticeable if sitting too close to the monitor, and it is not ideal for sharing your screen with someone else.
Mediocre vertical viewing angles. Due to the structure of TN panels, the image remains accurate at wider angles from above than from below. This is typical of monitors with TN-type panels and much worse than monitors with IPS type panels like the Asus VG279Q.
Decent gray uniformity. As with most TN monitors, the top of the screen is noticeably darker due to the poor viewing angles. There is only slight DSE, which is great, and in near-black scenes, the image is more uniform.
Out of the box, the XG2402 has great accuracy. The most accurate Picture Mode is 'Custom 1', but 'MOBA' is also good. White balance and color errors are low, and most enthusiasts won't notice the inaccuracies. Gamma follows the target curve, but is a bit bright, even with Gamma set to 2.4.
After calibration, the XG2402 has nearly perfect color accuracy. The remaining inaccuracies are too small for anyone to notice. Gamma follows the target curve almost perfectly.
You can download our ICC profile calibration here. This is provided for reference only and should not be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.
The ViewSonic XG2402 has excellent motion handling. It has an impressive fast response time, and motion is crystal clear with almost no visible blur. The backlight is free of PWM flicker, which is great, but there is no option to introduce flicker. It has an excellent 144 Hz refresh rate, and it has a wide FreeSync VRR range when connected via HDMI or DisplayPort.
The XG2402 has an outstanding fast response time. Most transitions are nearly instantaneous, and there is almost no measurable overshoot. This produces clear motion, with next to no noticeable motion blur. The lack of motion blur may bother some people if the frame rate drops too low.
The XG2402 has an excellent 144 Hz refresh rate (it is one of the best 144Hz monitors we've tested so far), great for gaming. It supports FreeSync over HDMI and DisplayPort, and both have the same wide FreeSync range. In graphically demanding scenes where the framerate drops too low, the monitor uses LFC to compensate, ensuring a consistent tear-free gaming experience.
Update 01/15/2019: We have tested the XG2402 with NVIDIA's new FreeSync drivers, and it works perfectly. When we tested it, FreeSync was automatically enabled on the monitor, and we had only to enable G-Sync in the NVIDIA Control Panel.
The ViewSonic XG2402 has great low input lag, excellent for gaming. Unfortunately, it only has a 1080p resolution and 24" screen, which may be disappointing to some users. It has a good selection of inputs, and can be used as a USB hub.
The ViewSonic XG2402 has outstanding low input lag, one of the best we've tested, slightly better than the MSI Optix G27C. The 60 Hz input lag is higher, but still excellent.
Only 1920x1080 is supported at 144 Hz.
The 3.5mm analog audio out port is a headphone port with adjustable volume on the monitor's on screen display. It supports DisplayPort 1.2, but this must be enabled on the OSD.
The ViewSonic XG2402 has some basic additional features. It has built-in speakers, but does not support HDR. There are no overlay options for displaying the frame rate or a crosshair when gaming. The OSD has a lot of options, but the layout is convoluted and can be difficult to navigate.
The XG2402 has a few gaming-oriented features, including:
The OSD always shows two pieces of information about the current state of the monitor. The bar on the left is the current power consumption of the monitor, expressed as a percentage of the maximum. The number on the right shows the current max refresh rate of the monitor, not the actual current refresh rate.
We tested the 24" ViewSonic XG2402. It is also available in 27" (XG2702), and for the most part, we expect our review to be valid.
If someone comes across a different type of panel or if their ViewSonic XG2402 doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.
The XG2402 we reviewed was manufactured in June 2018
The ViewSonic XG2402 is a decent monitor for most uses. It is a great gaming monitor (see our recommendations for the best gaming monitors and the best gaming monitors under $300), and it is aggressively priced to beat the competition. See also our recommendations for the best 24-25 inch monitors and the best budget monitors.
The ViewSonic XG2402 is better than the ASUS VG248QE. Overall, the two are very similar, with very similar performance under most uses. The XG2402 supports AMD FreeSync, making it a better choice for gaming. The XG2402 also has better color volume.
The ASUS VG279Q is much better than the ViewSonic XG2402. The VG279Q has better ergonomics, much better viewing angles, better gray uniformity, and an optional Black Frame Insertion feature. The VG279Q also has a larger screen, but the same 1080p resolution as the XG2402.
The Dell S2417DG is slightly better than the ViewSonic XG2402. The Dell S2417DG is a G-SYNC monitor, with a higher 2560x1440p resolution, so you can see more fine details in games or multitask easier. The ViewSonic XG2402 is a FreeSync monitor, great for Xbox One S/X gamers, or if you have an AMD graphics card. The Dell also has an option to introduce flicker to help reduce motion blur.
The ViewSonic XG2402 is much better than the ASUS VG245H. The XG2402 has a higher refresh rate, and a wider FreeSync range, ensuring a more fluid, tear-free gaming experience. The ViewSonic also has a better response time, so fast-moving objects appear clear with no blur trail. The ViewSonic also has much better color volume, although it has worse native contrast.
The ViewSonic XG2402 is better than the Acer XF251Q. The XG2402 has much better motion performance, thanks to the faster 144 Hz refresh rate. The XG2402 is also a bit brighter, and has a better color gamut and better color volume.
Although they use different panel types, the Acer VG271 is a bit better than the ViewSonic XG2402. The VG271 has an IPS panel, which has much better viewing angles. The Acer also supports HDR, and has better gray uniformity. The ViewSonic, on the other hand, has a much better stand and a faster response time, although, unlike the Acer, the XG2402 doesn't have an optional black frame insertion feature.
The ViewSonic XG2402 and the HP OMEN X 25f are very similar overall, and the best one depends on your needs. The ViewSonic is better if you need a more adjustable stand, as it has better ergonomics and can be rotated to a portrait orientation. The OMEN X has slightly better motion handling, though, so it might be better for some people.
The AOC AGON AG271QX is slightly better than the ViewSonic XG2402. The AG271QX is better at displaying large areas of similar color, as it supports 10-bit color. However, the main advantage of the AGON AG271QX is the larger, higher resolution screen, that makes it much easier to see fine details in games and for multitasking.
