Color Uniformity

LCD Color Uniformity

While the center of the ASUS ML248H screen has a decent dE when we analyze it more carefully, the rest of the screen does not fare as well. Only one other location on the screen manages a dE below 2.0, and two measurements are right around 3.5 dE. If you look at the graph you can see that most of the errors are occurring in the same colors, but when you move away from the center of the display, the quality of the grayscale really goes downhill.

I’m not sure why the grayscale is so close to perfect at the center and then far worse on the rest of the display, but I’d rather see the issues be in colors than in grayscale. If you are a photographer or artist, you likely aren’t considering a TN display anyway, but even for day-to-day office use the color shift in what should be neutral colors can be very annoying. If you don’t care about calibrating your monitor, then you really aren’t going to be too concerned with this, but for everyone else, the fact that only the dead center of the screen can be close to accurate is going to be an issue I would think.

Color Gamut

LCD Color Quality

The color gamut on the ASUS comes in on the low side for an sRGB display, with under 65% of the Adobe RGB colorspace represented. This likely contributes to the dE numbers we are seeing, as many of those values are at the edge of the sRGB colorspace, and the ASUS ML248H might simply not be able to produce them.

    Great article, have not read it. Wahoo.

    Shut up.

    And @ anyone at AT, can you introduce rules where you only review GOOD monitors. As in, nothing that has TN a panel. I know that will cut out a lot of stuff (AKA shit!) but theres still some good monitors out there that are actually worth reviewing.

    I disagree, I want to see companies get blasted in public for producing junk by reputable review sites like Anandtech and Tomshardware.

    I also want to know myself how these monitors perform.

    As far as me actually buying another TN panel - well, there's the 120Hz panels, and if they get 2560x1440 0r 2560x1600 120Hz TN panels that are top notch for TN I might just bite, but otherwise they are off my list.

    I really dislike TN panels. Hate it. But TN has always been awful, and now that it's better in 2011 than it was in 2003, it's still awful. e-IPS is the new TN -- able to slot into lower price points but with competitive (if not mindblowing) performance. In the laptop market you have to grin and bear it, but on your destop and in your pocket you don't have to. You can always choose a phone with an IPS screen, and now there are many more lower cost options for your desk. e-IPS and a few analogous VA paneled screens have at least decent viewing angles, color reproduction, and response times. e-IPS in particular is available in some dirt-cheap configurations with few options/no height or tilt/etc. and pricier products with more ergonomic functions and mo' betterness included. TN for desktop displays is really limited to 3D and 120HZ at the moment (I know some really like their TN panel displays, but there are cheap e-IPS options that are certainly worth a look). The U2311H and now the U23/2412 are midrange eIPS options, while NEC makes some much more expensive models. Asus and LG have some really decent eIPS models, and so I hope that prospective monitor buyers at least take a look at something other than a TN panel before making a buying decision. I hope that the explosion of mobile devices with great displays will leave people wondering why they put up with sub-par units in laptops and monitors.

    Asus makes this same chassis into displays with MVA and eIPS, in addition to the TN here. This monitor, in addition to it's two other-paneled siblings would make a nice article -- hint, hint _-.

    Agreed! A TN with an unergonomic stand so that you can not even try to work around its weak points. It doesnt even have a DVI output. So unintersting! Sadly someone will buy it..

    I'm so over TN panels. With IPS panels dropping close to 200 bucks, there's no reason to waste money on a TN panel.
  • iSmug - Thursday, October 27, 2011 - link

    Totally agree.

    The 24" A-MVA version is the same price. ML249H
    The 23" e-IPS version is $10 cheaper. ML239H

    I don't understand why anyone would want the TN version..

    I own the ML239H. It was by far the cheapest option for the monitors with the same LG panel.

    TN + 16:9 panel = waste of reviewspace
  • Daduck - Thursday, October 27, 2011 - link

    ..and included with an ugly design. Agree completely.
  • slick121 - Thursday, October 27, 2011 - link

    Agreed. I don't know who they are targeting but I wouldn't want that on my desk.
