The ViewSonic VX2453mh-LED screen itself isn’t particularly astounding to look at. Although the black plastic casing lets it slip into the background, there’s just a little too much frame running along the bottom of the screen – this makes the ViewSonic VX2453mh-LED look somewhat out of proportion.
It’s also surprisingly plain, and some extra lettering or an additional logo might have filled the space a little more effectively. The stand is also rather inflexible, and you don’t get any height adjustability here.
The ViewSonic VX2453mh-LED’s lack of heft is impressive though, and the casing is just 19mm at its thinnest.
It also has a pleasingly uncluttered set of ports and connectors. While most screens force you to fiddle around with the underneath of the screen, the ViewSonic places all of its outputs slap-bang in the middle of the ViewSonic VX2453mh-LED’s rear. You get an analogue VGA along with two HDMI ports.
No DVI is included, although a pair of HDMI connectors certainly atone – and are quite surprising given the relatively low price.
The menu system on the ViewSonic VX2453mh-LED is one of the most confusing we’ve seen recently. It’s fine when it allows you to access the main menu, but half of the time, for no apparent reason, it left us stranded in a series of arcane sub-menus which we struggled to navigate our way through. In the end, we kept closing down the menu and bringing it back up again until the main menu returned.
Neither are the keys – located inconveniently to the side of the screen – very easy to press, and we found it easier to simply pick up the flat-panel and use it like a tablet PC when trying to set it up. While it is possible with a screen this light, it’s hardly recommended.
The ViewSonic VX2453mh-LED screen resolution of 1920 x 1080 is good, and ViewSonic’s technology tries to create an optimum image in both 4:3 and 16:9 aspect ratios.
The listed contrast ratio of 1000:1 can, as usual, be further artificially boosted to stupid amounts – ViewSonic’s claim for this screen is a bewildering 30,000,000:1. And while this Dynamic Contrast Ratio feature can produce a nice burst of bright colours at select moments, we certainly wouldn’t recommend you to keep it switched on permanently.
Viewing angles of the ViewSonic VX2453mh-LED are fine. They’re nowhere near as flawless as those on an IPS panel, for instance, but for a flat-panel of this price, we were quite impressed with the lack of deterioration.
The ViewSonic VX2453mh-LED’s image quality is very easy on the eye. We didn’t find text to be perfectly rendered, so if you’re buying a screen for office applications then you might want to look elsewhere. However, the calibre of colour is extremely pleasing for the money.
At its best, the VX2453mh-LED’s images are cool and balanced, with enough colour to make their subjects realistic, but without ever feeling overpowering. The ViewSonic VX2435mh-LED worked well with Blu-ray films too – its dual-HDMI ports would make it particularly suitable for joint PC/BD player duties. And moving video was nicely recreated.
The ViewSonic VX2453mh-LED uses LED for backlighting, which allows it to keep power consumption down to impressive levels. According to the manufacturer's specs, the ViewSonic VX2453mh-LED typically consumes around 23 watt. Given that this is a large 23.6in screen, such a low figure is very creditable.
It also has an eco mode, and the screen is said to meet the standard of zero electromagnetic radiation, making this a potentially decent acquisition for green enthusiasts in search of a large screen.
