Viewsonic VX2453mh-LED - Image Quality and Performance
With a claimed 30,000,000:1 contrast ratio and 2ms response time, the Viewsonic VX2453mh-LED should in theory be just about the best-performing monitor we've ever seen. It's not of course, no surprise when it retails for under £150, but it's not bad.
Typical of a TN-panel, colours are not immensely vivid, but within its own arena, the Viewsonic can certainly stand up to rivals like the Samsung Syncmaster B2430H, but you'll get better colours from a PVA panel like BenQ's EW2430. Viewsonic's claimed contrast ratio is of course nonsense - the actual 1000:1 contrast figure is much closer to the mark.
The LED backlight is powerful, and mostly even. There's some slight bleed in the top corners, but this wasn't visible at all in everyday usage - only when looked-at carefully from within a darkened room.
Viewing angles are good for a TN-panel model too. Horizontal angles are great, the picture still eminently viewable from the claimed 160-degree position. Vertical performance is predictably a little less impressive, with some contrast shift when viewed from below, but again this is to be expected with a panel of this type. In normal usage, viewing angle limitations shouldn’t encroach on your viewing.
The Viewsonic VX2453mh-LED is designed to play along happily with both computers and consoles, and this is where some potential pitfalls crop up. Within the settings menu, each HDMI has different scaling options for AV equipment and computers. 1080p signals won't scale properly when using a PC when in the default AV mode, but switch to PC mode and it'll work perfectly - it just seems a little odd that the default is set to AV here.
When using the sRGB mode, the Viewsonic monitor consumes roughly 19.7w of power, which drops closer to 18.5w when normal brightness and contrast settings are used with the other colour temperatures. Naturally, this figure will go up if you shove up the brightness and turn down the contrast, but it marks this out as a fairly eco-friendly model.
You may have seen the Viewsonic VX2453mh-LED advertised as a 2ms response time monitor, but this is its grey-to-grey figure. Its actual response time is 5ms, but this is speedy enough for all but the most hardcore of gamers.
Samsung, Ilyama and BenQ all have attractive 24in models available at this price, but not all of them offer HDMI sockets. This Viewsonic matches other TN models on image quality, and has the bonus of being able to switch to a much less geeky-looking setup thanks to its convertible "book stand" base.
Offering decent image quality at a low price, the Viewsonic VX2453mh-LED enters an aggressive part of the market with an aggressively-specced monitor. The 30,000,000:1 contrast ratio is of course nonsense, but the dual HDMI inputs and a stand that lets it sit flush with a work surface or stand up like a standard computer screen give it a few worthwhile advantages over budget rivals.
