24" LCD Roundup

Introduction

Most people like to get as much information as possible when it's time to purchase and new, relatively expensive item. Unless you have money to throw around, you typically don't want to overpay for something that underperforms. That's where roundups of a product category can be particularly useful; unfortunately, it's not always easy to get all of the products in one place in order to put together such a roundup. What started as a review of a couple new 24" LCDs eventually grew into what you see here: a comparison of five of the most recent 24" LCDs to hit the market... that we were able to acquire. Note the qualification at the end of that sentence; there are still plenty of 24" LCDs that we have not yet reviewed, but for now we'll take what we can get. Besides, trying to put together all of the information for this article took enough time as it is.

We've discussed LCD panel technologies in the past, and we've often had negative comments for TN panels in particular. The biggest problem with TN panels is that they have far more limited viewing angles, often to the point where a minor adjustment in where you're sitting can affect what you see on the display. However, it just may be that there are benefits to TN panels as well. Look at most specifications and you will find lower response times advertised for TN panels than for competing PVA and IPS panels. Perhaps the biggest advantage for TN panels, however, is price. As the original LCD technology, TN panels have had a long time to mature and manufacturers are far more comfortable with them. Thus, it's little surprise that the prices are usually lower than what we find on S-PVA panels.

It used to be that all 24" LCDs used S-PVA panels, but that has begun to change during the past year. Cost has certainly been an important factor, but regardless we're beginning to see more and more 24" TN-based LCDs. Of the five new LCDs we're reviewing today, three use TN panels while two continue to use S-PVA panels. The latter do indeed cost more, but they also target a different market. Where the TN-based LCDs are intended for the consumer market, the S-PVA LCDs generally target the professional market.

We have a ton of information to cover in this article, so let's get to it. We're going to let the images do the talking for a lot of the areas we normally dwell on, and focus primarily on any noteworthy items that may not be immediately apparent. Also, feel free to consult our short glossary of terms that we use in our display reviews before continuing.

ASUS claims an impressive 130% color gamut for the MK241H. That seems rather high, and some of you may be wondering how exactly a display can be higher than 100%. The reason is quite simple: color gamut is usually measured against the NTSC standard, which is getting a little long in the tooth. Modern technology is thus able to exceed that standard, though it requires the use of an appropriate color space in order to do so. Naturally, we'll see whether there's any truth in the 130% claim.

Most of the remaining features are typical of an entry-level 24" monitor. The MK241H includes DVI, HDMI, and VGA inputs and it has built-in speakers (that as you might expect don't sound particularly good, but they'll get the job done if all you need is basic audio). In other areas, the ASUS LCD is more spartan. It lacks height, tilt, and pivot functionality; none of these are absolutely necessary, but we appreciate them nonetheless. The MK241H also lacks any USB ports, but it makes up for this by including an integrated webcam and microphone. That last is one of the few things that sets this LCD apart from other offerings.

The MK241H uses a TN panel, and the biggest drawback to such a panel is the limited viewing angles. TN panels have improved over the years, to the point where many people are no longer bothered by the viewing angle limitation. Still, they are clearly inferior in this area to PVA and IPS panels. Looking at TN panels from below is the worst-case scenario, and in fact they are practically unusable from this angle. However, this should not be a problem for most users unless you tend to work on your computer while lying down.
