Rolled out quietly onto the market, the Asus VS247H is a 24-inch LED monitor with a pleasant design and a modest set of tech specs. With a price tag of £170-£190, this monitor could prove to be a real bargain buy if it can hold its own against competitor models.

Hardware & Design: about average

In this field, the VS247H doesn't stand out from other monitors on the market. It has no original features and the only thing really worth mentioning is its connections. Video connections include VGA, DVI and HDMI sockets on the back of the display, while audio is taken care of by a simple headphones socket. As there are no built-in speakers, this mini-jack socket is the only way you can listen to audio inputted via the HDMI connection.

One great thing about this monitor though, is its design. It has a very slim casing, an integrated power supply and a stand that really does look like metal ... until you touch it. It will certainly look the part on your desk. However, as design is all a matter of taste, this doesn't boost the monitor's score in this part of our review.

Responsiveness: office computing and web browsing only

The responsiveness was as expected. We measured a ghosting time of 26 ms, which is perfectly in line with Asus' tech specs. The VS247H therefore isn't a monitor that's suitable for gamers, and is best used for general office computing and Internet browsing.

This graph shows the ghosting time, measured in ms, that the monitor takes to entirely remove the previous frame. The shorter the time, the more fluid moving images will appear.

The input lag, on the other hand, is within average with just a very slight delay that isn't noticeable to the naked eye.

Colours: accurate colours come at a price

With the factory settings, this 24-inch monitor doesn't display colours particularly accurately. The gamma curve (distribution of brightness) and colour temperature are off the mark and default colours give an average deltaE of 4.4.

This can be improved by switching the pre-set mode from Standard (the default setting) to sRGB in the monitor's menu. This largely corrects the defects outlined above and brings the deltaE down to 2.2.

However, changing to sRGB mode unfortunately has some collateral damage, as the screen brightness drops to 157 cd/m² and there's no way of pushing it back up without changing the other settings. This in turn has a negative impact on contrast levels—with the default settings, the VS247H has a contrast ratio of around 920:1, compared with 520:1 in sRGB mode.

We therefore think that anyone using this monitor should download a calibration profile. This makes the VS247H display accurate colours (deltaE = 1.2) and has less of an impact on the brightness and contrast (700:1).

So long as you have a 2.0 or 2.1 speaker set you can connect to the headphones socket, the VS247 is perfectly suitable for use with a set-top-box, media centre or DVD/Blu-ray player, which can be hooked up to the monitor's HDMI socket. However, given the monitor's low responsiveness, we wouldn't recommend connecting a games console (see review).

To get the best out of your movies, there are two things to bear in mind. First make sure you leave upscaling to the media centre/Blu-ray player. Then turn the brightness down as much as possible to help get rid of speckling snowstorms of noise in darker parts of the picture.


  • Design


  • Either accurate colours or decent contrast: you can't have both
  • Hardware could be better
  • Ghosting time too high for gaming (26 ms)


The biggest and only real advantage of the Asus VS247H is its sleek design. Otherwise, the ViewSonic VA2448-LED is a cheaper option that reproduces colours more accurately.
