The Viewsonic VX2478Smhl-4K ($469.99) is proof that you don’t have to spend a fortune to view 4K content, nor do you need a big screen. Based on Plane-Line Switching (PLS) panel technology this 24-inch Ultra-High-Definition (UHD) monitor delivers a sharp 3,840-by-2,160-resolution image with deep black levels and robust colors, and it comes with several future-proof video inputs. It can’t match the performance and feature set of our current Editors’ Choice midsize UHD monitor, the NEC MultiSync EA244UHD($1,499.95 at Amazon)(Opens in a new window), but it’s hundreds of dollars less expensive.
Design and Features
The VX2475Smhl-4K( at Amazon)(Opens in a new window) use PLS technology, which is similar to In-Plane Switching (IPS) panel technology in that it delivers better color quality and viewing angles than Twisted Nematic (TN) panels. The 24-inch screen is housed in a matte-black cabinet that is 1.9 inches thick and weighs 8.1 pounds. The cabinet has 0.85-inch, glossy-black bezels and is supported by a square, black base with a short mounting arm that gives you 22 degrees of backward tilt and 5 degrees of forward tilt. However, it doesn’t support height, swivel, or pivot adjustments. There are four VESA holes on the back of the cabinet for mounting the monitor on a wall.
Beneath the bottom bezel are four function buttons and a Power switch that are a bit difficult to reach, thanks to a piece of clear trim on the bottom bezel, and nearly impossible to identify, due to the use of black labeling against the black bezel background. At the rear of the cabinet are two HDMI 2.0 ports, one of which doubles as a Mobile High Definition (MHL) port for connecting to and charging MHL-compatible smartphones ands tablets. There’s also a DisplayPort 1.2 input and a headphone jack, but this monitor lacks USB connectivity. A pair of up-firing, 3-watt speakers provides loud audio, but very little bass response.

The VX2475Smhl-4K has six preset picture modes, including Standard, Game, Movie, Web, Text, and Mono modes. In addition to Brightness and Contrast adjustments, there are five color-temperature settings (sRGB, Bluish, Cool, Native, and Warm) and a User setting that lets you adjust red, green, and blue saturation levels. However, you don’t get advanced Six-Axis color settings like you do with the Acer H257HU($369.99 at Acer)(Opens in a new window) and the NEC EA244UHD, but you do get a Low Blue Filter setting, which helps reduce eye strain and three ECO modes (Standard, Optimize, and Conserve).
The VX2475Smhl-4K comes with a three-year warranty on parts, labor, and backlight. Included in the box are a resource CD, a Quick Start Guide, and an HDMI cable (you’ll have to supply your own DisplayPort and MHL cables).
Performance
The VX2475Smhl-4K doesn’t deliver what you would call spot-on accurate colors, but they’re not terribly skewed either. As shown on the chromaticity chart below, red, green, and blue color measurements (represented by the colored dots) are all on the outer edge of their corresponding boxes, which represents their ideal CIE coordinates. None of the colors are skewed to the point of oversaturation, however, and the misalignments do not result in tinting. Skin tones appeared natural and well-defined while watching Captain America: The Winter Soldier on Blu-ray disc, and colors looked sharp against the panel’s deep-black level.
The PLS panel did a good job of displaying light shades of gray on the DisplayMate 64-Step Gray-Scale test, but dark grays were slightly crushed, meaning the darker shades appeared black rather than gray. In this case the two darkest shades appeared black. Shadow detail on my test images took a minor hit as a result. Viewing-angle performance is equivalent to that of a good IPS panel; colors and luminance remained true from every angle.
The VX2475Smhl-K’s 4-millisecond (gray-to-gray) pixel response provided clean, ghost-free action while playing Grand Theft Auto V on the Xbox 360 and while playing Crysis 3 on the PC. The panel provided an input lag (the amount of time it takes for the monitor to react to a controller command, as measured by the Leo Bodnar Video Signal Lag Tester) of 11.1 milliseconds, which is relatively quick when compared with the ViewSonic VX2858Sml( at Amazon)(Opens in a new window) (27.2 milliseconds) and the Samsung U28D590D($69.00 at Amazon)(Opens in a new window) (35.1 milliseconds), but not quite as fast as our current leader, the BenQ XL2430T($449.00 at Walmart)(Opens in a new window) (9.5 milliseconds).
The VX2475Smh-4K consumed 30 watts of power while operating in Standard ECO mode, which is on par with other 24-inch monitors, such as the AOC G2460PG( at Amazon)(Opens in a new window) (32 watts) and the BenQ XL2420G (30 watts). Switching over to the Optimize mode lowered power usage to 24 watts, and the Conserve mode reduced it to 19 watts. The Conserve mode setting is fairly dim, however.
Conclusion
With the ViewSonic VX2475Smhl-4K, you get a capable 24-inch PLS monitor that delivers sharp imagery, inky blacks, and rich colors, for less than $470. It doesn’t offer extra features, such as USB ports and a fully adjustable stand, and its dark gray-scale performance is slightly skewed, but its 3,840-by-2,160-resolution panel does a fine job of displaying 4K content and it is outfitted with the latest video connections. If money is no object, our Editors’ Choice midsize UHD monitor, the NEC MultiSync EA244UHD, offers extremely accurate colors and excellent gray-scale reproduction, and it’s loaded with features, but expect to pay more than twice as much as you would for the VX2475Smhl-4K.
