Asus VS239H review: Asus VS239H

The Good Affordable IPS screen. With a little search, you can pick it up for under AU$170. Decent warranty term.

The Bad Buttons can be frustrating. Display a little too sharp. Not great for standalone HDMI device input. Limited defective pixel policy.

The Bottom Line The VS239H is a standard monitor that "does the job", albeit with a cheaper IPS screen rather than the inferior TN. If you have basic needs, this may see you through — just be aware of the limited defective pixel policy.

With the introduction of E-IPS, getting good quality imagery doesn't necessarily require robbing a bank first.

Asus' VS239H is such a beast, bringing 23-inches of IPS technology, with 1920 horizontal pixels and 1080 vertical. You're not going to find excessive inputs here or extra fancy features — this is a monitor aimed at fulfilling most people's basic needs, while still giving a decent picture.

Stand and ergonomics

Unless you're Dell, most monitor manufacturers don't offer a full range of motion in their stands, offering tilt only. Here, Asus is no exception. You won't find any cable management either, although the horizontally angled ports do go some way in reducing the appearance of clutter.

Asus' stand is exceedingly simple.

Buttons and on-screen display (OSD)

Asus mounts its buttons under the monitor, labelling them on the front of the screen. You'll have to operate by muscle memory, especially in the dark — the layout of the buttons don't feel particularly natural.

It's easy to win this one, vendors: front mount the buttons, back-light them and make the menu context sensitive.

The OSD is a simple menu driven affair, with categories on the left and options on the right. Asus doesn't really stray from the basic formula of brightness, contrast, sharpness and a couple of presets. We recommend you skip them all, set the monitor to "Standard" mode from the "Splendid" menu option, then hit up the "Color" section and adjust RGB values yourself through the "Color Temp" option.

A straightforward OSD for a straightforward monitor.

Performance LCD tests

After calibrating to a target brightness of 140cd/m² with an X-Rite i1Display 2, Eye-One Match 3 and tweaking with HCFR, the VS239H was run through the LCD tests.

Image tests
Contrast Sharpness Gamma Black level White saturation Gradient
Pass Too sharp Pass Pass Pass Very slight banding towards the dark end of the scale.

Asus' screen marches through the image tests, only slightly stumbling with gradients and providing an image that's slightly too sharp. The OSD prevents sharpness adjustments, unless you're using the VGA port, so there's nothing that can be done here.

Inversion pixel walk tests
Test 1 Test 2a Test 2b Test 3 Test 4a Test 4b Test 5 Test 6a Test 6b Test 7a Test 7b
Pass Pass Pass Pass Pass Pass Pass Pass Pass Pass Pass

The VS239H is the only monitor we've tested to pass all inversion pixel walk tests — most usually fail anywhere between one and four. Though there is very faint motion across each pattern, there's no visible flickering.
