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.
Disappointing contrast ratio. Blacks look gray in a dark room. These results are typical for TN monitors, and worse than most IPS monitors.
The ViewSonic XG2402 does not have a local dimming feature. The above video is provided for reference only.
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.
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.
Disappointing black uniformity. There is clouding visible across most of the screen, and the area around the test cross is significantly brighter than the surrounding screen.
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.

s.RGB Picture Mode: Custom 1 (calibrated)Adobe RGB Picture Mode: Custom 1
Excellent SDR color gamut, with nearly 100% coverage of the s.RGB color space. Adobe RGB coverage is decent, but insufficient for most professional users working in print.
s.RGB Picture Mode: Custom 1Adobe RGB Picture Mode: Custom 1
Excellent color volume. Unfortunately, it can't produce deep, dark colors due to the limited contrast ratio, but it fills out the color gamut well.
HDR is not supported.
HDR is not supported.
There are no signs of temporary image retention.
The ViewSonic XG2402 does a great job displaying gradients. There is some slight banding visible in most colors, but this shouldn't be an issue.
There is no noticeable color bleed when displaying large areas of similar color.
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 ViewSonic XG2402 is PWM flicker-free. Unfortunately, there is no option to introduce flicker to improve motion clarity.
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.
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.
Lowest input lag possible at the center of the screen, when the monitor is displaying an alternative resolution at its native refresh rate. The non-native resolution tested depends on the native resolution of the monitor, following this pattern unless otherwise specified in the Input Lag text:
|Native Resolution||Non-Native Resolution Tested|
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.
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 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 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 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 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.
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.
