Asus' new LS246H is a 24'' Full HD monitor with a thin glossy black frame resting on a very unusual stand. 

It's obviously aimed at users who want a stylish--luxurious, even--monitor.

Hardware: elegant, but not exactly useful

Because beauty is in the eye of the beholder, we'll move straight on to looking at the hardware.  It's clear that Asus has made more attention to style than it has substance, because the LS246H only has VGA and HDMI video inputs, along with a headphone jack for the audio signal carried by the HDMI cable.  That's too weak to score any higher than two stars in this section.

Excellent responsiveness

Average ghosting
over ten frames

This screen had a pleasant surprise in store for us.  As is so often the case, we were expecting a product whose only real selling point was an unusual design--but it wowed us with an excellent response time as well.  It's incredibly responsive, especially for a 60 Hz display.  It has absolutely no trouble displaying the fast movements that are a feature of some games, and will be perfectly at home both with the latest games and the most basic office use.

To round it all off, anybody who enjoys multiplayer gaming will be glad to hear there's nothing to fear here as the input lag is virtually nil, meaning there's no real delay between the action and what you see on screen.

Accurate colours with factory settings

Measured Colours

Ideal Colours
Compare the Asus LS246H to other LCD monitors in our Product Face-Off

Using the factory settings, our colour measurements confirmed we had a very accurate monitor on our hands, and the average deltaE was below 2.3.  Remember that when this reading is under 3.0, the difference between a reference colour requested by the graphics card and wheat's actually shown on screen is imperceptible for the majority of people.  In practice, we found that the different shades of grey suffered from both a slight red tinge and too much brightness.  If you're one of those people who needs more accurate colours than most, then you can download a calibration profile.

Another welcome finding was that that the contrast ratio was above 1 000:1, easily beating our usual average of around 850:1.

If you're looking for a monitor to do a lot of photo editing, the LS246H might not be the right monitor for you.  You'd be better off with a screen with an IPS or VA panel.  Both technologies have wider viewing angles and more even colours across the whole display.

Upscaling SD sources needs work

The LS246H didn't do brilliantly at upscaling SD sources like DVDs.  You'd better use a source that can produce a 1080p signal itself.
Mirror, mirror on the wall ...
Asus makes no bones about it: the LS246H really could be a mirror, and the combination of a glossy finish on the screen itself and the glossy plastic bezel only serves to reinforce this impression. Its website makes a virtue of this "mirror finish."

The fact that you can see yourself in it when it's switched off isn't a problem--but when you still can when it's switched on is.

If you've fallen for the LS246H, you should know that there are some things you can do to reduce the impact of reflections. There are three steps:

1 · don't put the screen in front of a window or other light source

2 · don't turn the brightness down. If it's too low, it won't be able to counteract the ambient light. Don't worry about your electricity bill either: even at its maximum brightness, the monitor only consumes 30 W.

3 · don't touch the screen! Even a single fingerprint can take ages to clean!


  • Accurate colours with factory settings
  • Good response times
  • Elegant design


  • TN panel, so poor vertical viewing angles
  • Basic hardware
  • Glossy finish susceptible to reflections


The LS246H has great response times, accurate colours and good contrast, but without a few hardware tweaks or wider viewing angles, it can't quite expect five stars.
