ViewSonic is one of the most popular brands when it comes to display panels and projectors. We had the opportunity to visit their HQ at Taiwan a few years ago and I must say to this day, they still cater to a wide range of audience – be it for the mainstream, professionals and of course, gamers.

Now what we have here is the ViewSonic XG2405. A gaming monitor with 144Hz of refresh rate featuring a 23.8″ IPS panel with 1ms of response time via back-light strobing support. The monitor also comes with AMD FreeSync technology – which is a nice addition to its features. This is a $300 USD monitor (11,000 PHP locally!), joining the rising number of budget oriented Panda IPS panel based options.

Packaging and Accessories

ViewSonic had the XG2405 packed inside an environment friendly packaging. The product should come with the following items inside:

  • Power cord
  • HDMI cable
  • Quick start guide

Design, Layout and Build Quality

ViewSonic certainly took some notes from the more expensive XG series when they designed the XG2405. Sleek is the word we’re looking for here with of course the exception of the faux-aluminum stand (your taste may vary). Still, this is a unit that looks on par with any other $300 gaming monitor in the market.

ViewSonic chose to go with an anti-glare coating with a 3H hardness for the XG2405. This is more matte, less gloss kind of coating which is much appreciated for environments with tons of light sources available. The 3H hardness level will also better protect your polarizer from potential damage.

Ergonomically, the XG2405 could be lifted, tilt, swivel and pivot. Other recent gaming monitors at its price range lacks some of these ergonomic options so we applaud ViewSonic’s approach at this price bracket. Cable management, a carrying handle (with built-in headset mount) and a non-obtrusive stand size are also good parts of the deal. Buttons are located on the back too – nice. Note that it also supports VESA mounting.

ViewSonic XG2405 Gaming Monitor 1

Display options are understandable at the very least. We have dual HDMI 2.0b ports here, a DisplayPort 1.4 and a 3.5mm audio-out. We also got a cute cable management clip at the stand should you really require the use of one.

ViewSonic XG2405 Gaming Monitor 2

Power is internal which is a plus for us who hates looking at power bricks. Cooling is of course sufficient enough for such configuration with perforations at the top and bottom end of the panel.

On-Screen Display Menu

OSD is based on a button input so it is not the most intuitive out of the box – middling, I’d say. As for the menus, we have six main menus here with up to three layers of navigation depending on the settings.

ViewSonic XG2405 OSD 1

Audio Adjust is self explanatory with only a volume option to play with. Who needs mute anyway? Right.

ViewSonic XG2405 OSD 2

View Mode is where you could select profiles. We’re glad to see a profile for MAC here (YCbCr/YPbPr) as well as a Mono profile – haven’t seen that one in ages.

ViewSonic XG2405 OSD 3

Color adjust is where most of the settings required to calibrate the display is located. Not sure why ViewSonic combined the Contrast and Brightness in one option here. It is just not intuitive to do so especially with the space available.

ViewSonic XG2405 OSD 4

Manual Image Adjust on the other hand is where advanced image and gaming options could be found. Response Time and Black Stabilization are the only options to watch out here for gaming.

ViewSonic XG2405 OSD 5

AMD FreeSync and 1ms Mode are located on the Setup Menu which is kinda odd. I’d rather see these options with the other gaming oriented options.

ViewSonic XG2405 OSD 6

Over all, navigating the UI is just borderline decent together with the button based input. Note that there are no gamma level options too so it is just as limited as the other gaming monitors at this price point.

Test Setup and Methodology

Our test setup relies on the Blur Busters TestUFO Motion Tests and the Data Color Spyder5ELITE Display Calibration System. The cameras used throughout the review for the motion artifact and high speed assessments are the Fujifilm XE-1 and the Nikon 1 J1.

Test System Specifications
CPU Intel Core-i5 6600K
Motherboard ASUS Z170-A
Cooler Noctua NH-L9i
Memory ADATA Premier DDR4
Storage Crucial BX200 480GB
Case Thermaltake Core P3
Display DELL U2715H
OS Microsoft Windows 10 Pro

Target for calibration is a 2.2 Gamma value, with a White Point at 6500K and a Brightness value set at 120 cd/㎡. Calibrated values are then analyzed with the Spyder5ELITE Display Analysis tool. Do note that Dynamic Contrast Ratio and other extra features built within the OSD are disabled during the tests. The following OSD values are selected for the display calibration.

OSD Settings
Brightness 36
Contrast 70
Saturation NA
Temperature Native
Gamma NA
Preset Standard

If you wish to use the calibrated ICC profile taken from our Spyder5ELITE result, just send us a message. You may also read our guide on how to use ICC profiles.

Color Gamut

The Color Gamut test evaluates the color space coverage of the display panel from industry standards such as sRGB and AdobeRGB. Higher percentage values are better.

ViewSonic XG2405 Benchmark 1

sRGB color coverage is 100%, while we have a 81% coverage for the AdobeRGB color space. Pretty good initial results thus far.

Tone Response

Tone response is where we check the display panel’s Gamma value and presets if there are any. We then compare the results with the industry standard Gamma level at 2.2. Closer to this value is better.

ViewSonic XG2405 Benchmark 2

The Gamma value we got from the result is exactly 2.1. Gamma correction could only be achieved by adjusting the monitor’s brightness, contrast or with software based options. Lucky for you, the XG2405 features black level adjustment so that might work too if you really want to target a certain value.


The test here will shows us an overview on how the display performs at its maximum brightness level. This is measured in candela per square meter (cd/m2). Higher is better.

ViewSonic XG2405 Benchmark 3

Panel brightness at 100% is rated at 232.4 cd/㎡. This is 13.6 nits lower than the specified 250cd/㎡. Pretty good result actually.

Contrast Ratio

Static contrast ratio is also tested. The test here will shows us how the display performs at its maximum contrast level measured in luminance ratio. Higher is better.

ViewSonic XG2405 Benchmark 4

Now static contrast ratio is rated at 970:1. Again, near the specified value and is among the best performers on our chart.

Screen Uniformity

This test shows us an overview of the display panel’s screen uniformity at maximum brightness level. The closer this value to 0, the better the quality of the panel.

ViewSonic XG2405 Benchmark 5

Screen uniformity is also among the top-notchers. The only offenders here are the top-center and the top-right part of the panel. Other than those mentioned, the monitor’s display panel is pretty much uniform across the areas tested.

Color Accuracy

The color accuracy test shows how different basic color hues are reproduced by the display panel. These color tones corresponds with the Datacolor SpyderCheckr. Lower Delta-E values are better.

ViewSonic XG2405 Benchmark 6

The XG2405 scored an average of 0.66 Delta-E value. By far the most accurate display we’ve reviewed as far as the SpyderCheckr tool is concerned.

Power Consumption

The power consumption is checked with a power meter. Measurements are taken at maximum brightness level.

ViewSonic XG2405 Test 5 1

At 28.7W, it is one of the least power hungry 24-inch panel we’ve tested to date.

Button to Pixel Input Lag

Our Button to Pixel Input Lag result is the combination of latency from the point of input, processing and display output. To quantify the display panel input lag, we utilized Quake 3 Arena as our main shooter. The game is set at the panel’s native resolution with the FPS locked at 250. We check how much delay in milliseconds it took the monitor to actually output the signal via a 1200 FPS high-speed camera with ~0.83ms of accuracy.

ViewSonic XG2405 Benchmark 9

Our button to pixel input lag test result shows that the ViewSonic XG2405 has an average latency of 5.8 ms. The 5th fastest overall and the 2nd fastest IPS based monitor we’ve tested so far. Note that we’ve tested all response time modes and we got similar results regardless.

Motion Clarity: MPRT

Motion Picture Response Time (MPRT) is the numbered approach to demonstrate the level of perceived motion blur on a display. Basically, a lower persistence value indicates less motion blur. Refresh rate and the sampling method plays a major part here whereas a higher refresh rate nominally features better display persistence values.

ViewSonic XG2405 Benchmark 8

These results are references to check out the theoretical MPRT values of a display. Head over to our Pursuit Camera test for the visual representation of the actual values.

Motion Clarity: Pursuit Camera

Setting up a pursuit camera courtesy of Blur Busters allows us to a great extent, perceive the actual motion blur of the display. Using such method also allows us to check out for other motion artifacts including ghosting, inverse ghosting and other artifacts. This pursuit camera test is a peer-reviewed invention.

ViewSonic XG2405 Test 3

Response time at standard, advanced and even ultra nets the same visual result – similar to the input lag test. Not really worthy setting the thing up. What’s worthy though is the 1ms mode at the expense of a static brightness level of about 100 nits. PWM artifacts are visually more apparent as well compared to other monitors with strobing.

Backlight Bleed

Backlight Bleed is the phenomenon where backlighting from a display leaks. This is prevalent with LED backlight enabled displays where the LEDs used to light the panel are situated at the edges of the display. Testing the Backlight of the display is conducted on a dim room, simulating the recognizable amount of bleed for such scenario.

ViewSonic XG2405 Test 2

Back-light bleed is not a problem with this display. Pretty much uniform around the edges.

Viewing Angles

Viewing angles are also tested to check out how the display panel performs on various positions. This should be helpful if you are looking for a panel that could be used on multi-monitor setups.

ViewSonic XG2405 Test 5

Excellent visual results we got here from the XG2405. Just what I expected from an IPS panel.

Frame Skipping

Frame Skipping is the phenomenon where dropped frames and missing refreshes occur due to ineffective refresh rate overclocking. We are are utilizing the Blur Busters Frame Skipping Checker to test if there is any. If your display exhibits such issues, it should be perceptually similar to in-game frame skipping.

ViewSonic XG2405 Test 1

No worries here when it comes to our frame skipping test. Everything’s smooth at 144Hz.

Software, Lighting and Special Features

On top of the 144Hz refresh rate, the ViewSonic XG2405 also supports AMD FreeSync. Not the Premium nor the Premium Pro versions of the feature technically but it supports LFC with a tested range of 48-144Hz. This basically qualifies the XG2405 for the FreeSync Premium.


As tested, the gaming monitor comes with back-light strobing in the form of ViewSonic 1ms Mode. It doesn’t work with FreeSync though so keep that in mind.


If you don’t want to use the built-in window splitting feature of Windows 10, then ViewSonic had the ViewSplit bundled with the display. Pretty useful if you want to work with your own presets.

ViewSonic XG2405 Test 4

There are dual 2W speakers built-in but they are not particularly interesting. Output is just borderline decent.

Final Thoughts

The ViewSonic XG2405 is one of the best gaming monitors we’ve tested in recent times – with a few drawbacks of course. Regardless, it showed exceptional performance for something with a $300 USD price point.

First off, panel’s quality is on point. Screen is uniform across most areas and performance are damn near the specifications. I know that should be the case 100% but I’m just so used to brands that doesn’t really care if their products could follow what’s written on the box.

Ergonomically, the package is just well executed – with a grab bar and a cable management option as a part of the deal as well. There’s basically no need to get a VESA mount – unless you want to stack this one on top of another panel.

Coming in hot locally at 15, 990 Pesos, the ViewSonic XG2405 is one of the best gaming monitors we’ve tested in recent times. Oh wait, I’ve said that already. It’s that good.
