A Review of the ViewSonic VX2475SMHL-4K 24-Inch 4K Ultra HD LED Monitor
ViewSonic seems to be playing a strategy of positioning itself as a leader in the advanced but affordable 4K PC monitor industry. In the wake of other ViewSonic offerings with excellent future-proof specs such as the ViewSonic VP2780 4K 27 inch monitor, the manufacturer has now also started shipping out the VX2475SMHL-4K 24-Inch 4K Ultra HD LED we’re reviewing here.
Just like its bigger cousin which we reviewed earlier, the VX2475SMHL-4K offers a wide range of excellent specs which are designed for future-oriented use. This “future-proofing” has been applied particularly to the connectivity technologies of the VX2475SMHL and they consist of both HDMI 2.0 ports and DisplayPort 1.2a connectivity. The monitor also offers support for MHL, thus letting MHL-capable devices get their electrical charge from the VX2475SMHL while they’re connected to it.
The VX2475SMHL also offers excellent refresh rates and a solidly quick response time, so it’s clear that ViewSonic built this machine to be particularly 4K gamer-friendly but also a highly useful and affordable rig for professional graphics and photography uses. Other specs for viewing presets back this latter design direction up in the VX2475SMHL and best of all, this particular ViewSonic PC display is very nicely priced. It’s barely been released and it sells for well below $500.
The good aspects of the VX2475SMHL are numerous and combine together to make a nearly ideal 4K gamers package or light pro users personal work monitor with 4K resolution.
The VX2475SMHL offers excellent connectivity options for both gamers and those interested in connecting external 4K-friendly media to their PC. With its HDMI 2.0 connection ports, the VX2475S gives you access to one more option for 4K at 60Hz than is typically available in many ultra HD monitors. On top of this, there is the advanced DisplayPort 1.2a connection for still more high Hz 4K connectivity and a range of viewing presets for users who want to do their visual design work on the VX2475S.
Furthermore, the VX2475S offers users the nicely wide angle viewing qualities of the company’s SuperClear PLS panel technology, which is designed to allow undistorted or unfaded viewing of onscreen imagery at angles of up to 179 degrees. On top of this, the VX2475SMHL-k also comes with built-in speakers, a headphone jack and technologies for making the visuals easier on the eyes.

The VX2475SMHL is still very new on the market and some of its lesser aspects haven’t yet been explored as much as we’d like. However, a couple of things can be pointed out right now about this model that might annoy some potential buyers.
For one thing, the screen of the VX2475SMHL-4k is definitely not as large as many professionals might like. At 24 inches, it’s well below the more usual sizes of pro or mid-grade 4K monitors oriented toward design and video editing work. While having 4K on a 24 inch screen results in some fantastic pixel density, the overall work surface of the display could leave a lot cut off from viewing without scrolling in larger visual design projects.
Furthermore, while definitely not the best option available as a professional design monitor, the VX2475S also doesn’t deliver the best kind of 4K gaming oriented specs. Its response time isn’t slow, but neither is it as fast as that of many TN screens which sell for similar prices. These are minor issues though and overall, we’re looking at a great piece of technology for its class.
It’s still a little bit early to tell for sure, but the ViewSonic VX2475S is looking like it will be a fine addition to the low-cost 4K monitor market. It’s inclusion of HDMI 2.0 along with DisplayPort 1.2a makes it a great piece of technology as far as connectivity goes. What still needs to be seen is how well consumers accept its visual specs and performance at displaying 4K game graphics. You can also take a look at the Samsung UE590.

As we’ve already covered to some extent, the VX2475S offers a number of features inside its rather small body.
The HDMI 2.0 of the monitor basically ensures that the connectivity package stay current for at least the near future of gaming and external media devices, particularly with 4K resolutions. While most 4K-friendly and normal GPU’s today still firmly use DisplayPort 1.2 as their main means of connecting to a monitors inputs, Nvidia’s newest GTX and Titan lines of graphics cards are indeed also installing the HDMI option and the VX2475S is ready for this.
It’s HDMI 2.0 ports also make it ready for the future possibility of being able to stream 4K media-box movies and shows to a 4K PC. For now this still isn’t really possible due to the content protection issues surrounding movies being downloaded to PCs but this will almost certainly change sooner or later and the HDMI connections of the VX2475S will come in handy when it does.
The VX2475SMHL also features a quick 2ms liquid crystal response time. This is great for gaming uses and works to reduce streaking, blurring or ghosting on the screen. ViewSonic delivers this response time through the company’s ClearMotive II imaging technology and by using their Color a-Si Active Matrix TFT LCD panel types to create something close to the response times of TN monitor screens without some of the viewing angle issues that TN involves.
The dual integrated stereo speakers of the VX2475SMHL are nothing particularly awe-inspiring but they’re a decent addition to such an affordable 4K monitor, and they do offer a respectable amount of 3W power for slightly enhanced multimedia sound at a decent level of clarity.
Finally, we should also mention the ViewMode setting that the VX2475SMHL comes with. These are several different presets that go by the titles “Game”, “Movie”, “Web”, “Text”, and “Mono”. By simply activating each of them, you can quickly have the “ideal” gamma curve, color temperature, contrast, brightness and other visual specs for each of the above uses. This is pretty useful for casual users though it might leave something to be desired in a professional visual editing context.
Oh yes, and the VX2475SMHL is a VESA mountable 4K PC monitor, a minor detail but a useful one for more positioning flexibility, and some monitors out there don’t actually include VESA mounting.

For its low price and category, the ViewSonic VX2475S doesn’t offer a half bad package of visual specs, particularly for gamers.
First of all, the ultra HD resolution looks great on the smaller screen. At 24 inches but with 8.2 million pixels, the VX2475SMHL offers some definitely superb pixel density, greater than that found in many other larger 4K monitors, and you’d have to strain very close to actually even see pixilation of any kind.
Furthermore, the color technology of the VX2475SMHL is not too bad. While it doesn’t offer AdobeRGB coverage and much less coverage of more professional gamuts like the DCI-P3 standard, the VX2475SMHL does give you the solid 100% of the basic sRGB spectrum and this is pretty much good enough for gaming and any casual or light design uses. Furthermore, the color gamut is enhanced somewhat by ViewSonic’s Super Clear PLS technology, which offers exceptional color performance with direct viewing and extends reasonably good viewing to wide angles of 178 degrees both horizontally and vertically.
In terms of contrast and brightness, the official ViewSonic figures for both of these are 1000:1 and 300cd/m2 respectively. Knowing that virtually all monitors perform below these factory ideals in actual practice, most users can probably expect a decent contrast ratio of between 500 and 900:1 and a brightness of 230 to 290 cd/m2, which is a bit on the dim side but not terrible.
Finally, ViewSonic also included some nice little bonus features for comfortable viewing such as their Flicker-Free technology and Blue-Light Filter. The former uses DC modulation backlighting that maintains a steady stream of direct current power and thus smoother, closer to constant backlighting (thus minimal flicker) and the latter technology involves a Blue Light Filter setting for adjusting how much blue lighting is emitted by the screen. As a final note, 60Hz refresh rates in the VX2475SMHL are guaranteed thanks to the already mentioned HDMI 2.0 and DisplayPort 1.2 connections
We’ve already pretty much covered the connectivity options of the VX2475SMHL in the sections above but suffice to say, it is nice to have at least two media/GPU connection options that offer refresh rates at 60Hz. The HDMI 2.0 in particular will be useful as new PC-oriented media content devices arrive on the market with 4K programming loaded into them.
Furthermore, the DisplayPort 1.2a is a step up from the more usual and common DisplayPort 1.2 and it includes the option of VESA Adoptive synch technology for synchronizing variable refresh rates between monitor and PC GPU. Furthermore, though AMD FreeSync isn’t available in the VX2475SMHL, Display Port 1.2a is its ideal operating connection type.
Finally, this ViewSonic monitor is integrated with an extra HDMI 1.4 port and MHL connectivity, enabling devices such as smartphones and tablets with the same MHL capability to charge themselves while also connected to the monitor for download and upload of content.
The price of the ViewSonic VX2475SMHL is one of its single best features. This PC display costs just $436.99 on Amazon.com and while it’s not anywhere near the top of the pile in terms of specs, for this price, the VX2475S offers a very good pile of features and specs.
