I own a 24-inch Dell UltraSharp 2408WFP LCD computer monitor. Over the last year or so, I've yet to have a performance issue. I do a heavy amount of gaming on it including World of Warcraft and first-person shooters, and I've never once had a problem with input lag. Input lag is a delay measured by the difference between the time a signal is input into a display and the time it is shown by the display.
Input lag is one of the major criticisms of this monitor from its users. Just to be clear, I'm not claiming that input lag on this monitor doesn't exist, I'm only saying that I've not seen evidence of it on either our evaluation unit of my own. Dell has purportedly addressed the issue in the A02 revision of the 2408WFP.
That being said, I still feel the Dell Ultrasharp 2408WFP is the best 24-incher money can buy and quite easily earned the top spot on CNET's top-rated 24-inch LCD computer monitors (that we've reviewed). From its S-PVA panel with great viewing angles, its deep blacks, and multitude of connection options, there is none better for overall value. It's the most expensive on the list, but it's one of the few monitors in the $400 range ($440 at the time of this post) that's well worth its price.
The rest of the list consists of the 16:9 Dell G2410, which got high marks for its low power consumption and excellent performance, including great movie playback. The HP 2408h is another very good monitor, with its lack of a DVI port--or a DVI-to-HDMI cable--as its only major stumbling block.
The Dell S2409W is a 24-incher that sacrifices features for price, but makes up for it in performance and ease of use. Lastly, the Acer G24 is simply the best gaming monitor I've seen. While it doesn't include many features or extras, what it does (gaming), it does extremely well.
Agree or disagree with the list? I've love to hear why. Voice your opinion in the comments section. Also, be sure to look out for new monitor reviews here.
