Acer T230H review: Acer T230H

Acer's T230H is a passable screen that makes some good ground with the build quality, but loses it again through silly design decisions.

Craig was sucked into the endless vortex of tech at an early age, only to be spat back out babbling things like "phase-locked-loop crystal oscillators!". Mostly this receives a pat on the head from the listener, followed closely by a question about what laptop they should buy.

The T230H is one of Acer's gifts to the touch generation. We're still not sold on Windows 7 touch — sure, it's the best Windows has ever been integrated with the feature, but it still feels largely pointless and tacked on, especially on the desktop. We can see it (sort of) in all-in-ones, but stand-alone monitors? Nah. Leave touch to the single purpose devices, and we'll continue to use keyboards and mice on desktop PCs, thanks.


Acer T230H

The Good

Great stand considering the screen size, with height and swivel adjustment. Good build quality.

The Bad

Insane price. No dedicated input switcher. Auto switches to a live input if another input goes to sleep. High power consumption. Bottom-mounted buttons. Lacklustre HDMI performance. Typical bad monitor sound. Buggy touch functionality with multi-monitor.

The Bottom Line

Acer's T230H is a passable screen that makes some good ground with the build quality, but loses it again through silly design decisions. The gloss screen, lack of dedicated input switcher, high power consumption, not-thought through touch functionality, premium price and the lacklustre HDMI performance lead us to recommend you look elsewhere.

Regardless, the T230H is quite the well constructed beast, reminding us a little of Dell's previous generation of UltraSharp range, particularly because of the stand and ergonomic features therein. Tragically, this is where the similarities end. For a start, Acer has chosen to include a glossy screen, meaning much higher glare and reflectivity than usual.

The touch software is also not thoroughly thought through. For multi-monitor set-ups, the T230H registers touch just fine, but if you have another screen set as primary, the click ends up there instead of on the Acer. Vexing indeed.

Another oversight — when the monitor is turned off, the screen still receives touch input. Should you ever want to clean the thing, you'll need to yank the USB or power cable to avoid entering click hell.

It is multi-touch, for what it's worth — Windows Photo Viewer and anything else that supports it will accept two fingers just fine to pinch zoom and rotate, although if you use more than two, it starts getting a bit confused.

The Acer uses infrared technology for the touch, which means you don't actually have to touch the screen for it to receive an input. A few times when hovering our finger close to the screen but not touching, it registered a click. This makes quick writing or drawing difficult, with you needing to lift your hand further away than normal from the screen if you intend to get an actual break on screen, rather than a continuous line.

Stand and ergonomics

The T230H is a cut above most stands you see in this range, and is heavily reminiscent of Dell's last generation UltraSharp stands. From the "flying V" legs, to the central swivel point, rack and pinion height adjust, tilt and hole-in-neck-style cable management, someone at Acer has clearly decided that imitation is the best form of flattery. The only thing it's missing is pivot to put it in portrait mode, and the ability to lift the panel itself off the stand.

Well done Acer, even if it is a blatant copy of Dell's older stand.

The T230H is decked out with some fully sick ... no, wait. It's a pair of 1.5W speakers that are tragically underwhelming, have little volume, no definition, sound distant yet somehow manage to distort easily, and you'd do a million times better with any stand-alone speaker set.

This is pretty much standard with any monitor speakers, so we won't be too harsh on Acer here, but we sure wish someone would follow Apple's iMac lead and bundle something decent for a change. Or just leave them out — they're only adding cost.

Buttons and on-screen display (OSD)

Acer's buttons are not only situated under the display, but are rockers that are smaller than the labels lead you to believe, resulting in many frustrated missed hits, and difficulty navigating anywhere. We found ourselves tilting the monitor up just so we could see the buttons and minimise mistakes. It is, in a word, vexing. There is no quick input switch button either; you'll have to go through at least eight button pushes before you get the option to switch to your device of choice.

Another annoyance arose here: if you're using multiple inputs, and one of your machines goes to sleep, the T230H will automatically switch to another machine that isn't asleep. In our test case, the computer would turn the monitor off, then the monitor would auto-switch to the running PS3. We couldn't find an option to turn this off, and to our eyes it's nothing but potential power wastage.

Acer's OSD is understated and easy enough to navigate, awful buttons aside. It offers nothing about the standard menu options.

Of course, what it does offer is the usual glut of presets, this time under the moniker "Acer eColor Management". We have "User", "Text", "Standard", "Graphics" and "Movie" this time, although as always we recommend leaving it on Standard, and then turning eColor Management off through the OSD.

Lagom.nl 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 T230H was run through the Lagom.nl LCD tests.

Pass Pass Pass Pass Couldn't differentiate level 254 from white Banding towards dark end of the scale, purple/green discolouration

Pass Flicker Slight flicker Pass Flicker Slight flicker Pass Pass Pass Pass Pass

The gradients aren't the best on the T230H, nor is its ability to discern true white when calibrated. It failed four of the pixel walk tests, but up to four failures here is typical for LCD screens.

Input lag
Measured against a Samsung SyncMaster 975p CRT, and using a Canon 40D set to a shutter speed of 1/320, an average of over 60 photographs were taken using Virtual Stopwatch Pro. The average result over DVI came in as 0ms — in what is becoming a trend for TN-based screens, the T230H actually posted a number of scores that were faster than the CRT, in some cases upwards of 20ms.

Colour accuracy
ΔE is the measurement of how far a measured colour deviates from its expected value, allowing us to determine the colour accuracy of a monitor. While a ΔE value of 1 is considered perceivable, as long as it's less than 3, the shift shouldn't be too obvious. HCFR was used to determine ΔE for the monitor, and dynamic contrast ratio was turned off.

Not the worst we've seen, but those greys are way out and the gamma is shot. Let's see if we can get things a bit better with Eye-One Match 3 and HCFR.

We had a heck of a hard time calibrating the T230H, which seems to be something common among touchscreens. Blues didn't register accurately until the colour values were brought right down below 50, and even after significant tweaking in HCFR, we weren't able to coax any more accuracy out of it. For a low-end consumer monitor, this is not the be all and end all, but compared to its competition, the T230H suffers.

HDMI performance
While a monitor might have an HDMI port that's no guarantee it'll display images as expected. We hooked up a PlayStation 3 and checked for 24p capability, as well as judder and ran the HQV Blu-ray test to see how well it coped with an interlaced source and noise.

1080i content on the T230H was jumpy, and as you can see from the HQV tests, wasn't filtered as well as it could have been. 24p is off the cards, and panning both horizontally and vertically created judder in our Mission Impossible III test chapters. You can certainly watch movies over HDMI on the T230H, it just won't give you the best experience.

Viewing angles
Viewing angles were taken with a Canon 40D in spot metering mode, with only shutter time adjusted to obtain a good exposure.

Backlight uniformity
Backlight uniformity was measured by placing HCFR into free measure mode, displaying a completely white image and recording the brightness along a 5x3 grid on the screen. This should be considered a guide only, as backlight uniformity is likely to change from unit to unit.

Light bleed
The T230H exhibited obvious light bleed from the top of the screen, and a faint glow from the bottom.

It's important to note that the effects of light bleed will likely change from monitor to monitor, regardless of make.

Power consumption
We measured power consumption using a Jaycar mains digital power meter. It's important to note here that due to limitations of the meter, measurements are limited to values of 1W and greater, and are reported in 1W increments.

All measurements, screen brightness and contrast were set to 100 per cent, and a test image displayed.

Maximum power draw 41W
Power-saving mode 7W
Off 7W

That's a huge draw for a screen of this size — even the SX2210T from Dell doesn't get near it. Acer's G225HQ does though, which leads us to two conclusions: adding infrared-based touch doesn't add too much to the power draw of a monitor, and Acer really needs to look into its power consumption.


Acer covers the G225HQ with a three-year pick-up and return warranty. If the user finds any dead pixels seven days after purchase, Acer will arrange a pick up and return repair. We are still waiting for Acer's response in regards to its policy after this period ends.


Acer's T230H is a passable screen that makes some good ground with the build quality, but loses it again through silly design decisions. The gloss screen, lack of dedicated input switcher, high power consumption, not-thought through touch functionality, premium price and the lacklustre HDMI performance lead us to recommend you look elsewhere.
