Hi, I'm trying to decide between monitors (either the 24" U2410, the 24" ST2410, or the 22" SX2210 - all of them are dell and all of them are 1920x1080). This will be primarily for gaming (world of warcraft). When I was reading some information on selecting a monitor it seems everyone prefers the 24" and some people even suggested the 24" is the best size for the 1920x1080 resolution. Is that true? And here is my reall naive question: wouldn't a 1920x1080 look better on a smaller screen (like the 22" SX2210) rather than one of the 24" screens? Because isn't the picture kind of stretched on a larger screen? I can hear you all laughing at my question right now lol
Also, I might not be able to afford the U2410 right now, but if anyone out there has any of these monitors and can give me feedback regarding picture quality/ghosting/seeing big pixel blocks during gaming then that would be great too!
You are right that on the smaller monitor the higher resolution would look sharper, but it will also be smaller and a high resolution is not the only way to judge the picture quality.
Dell makes pretty good monitors, especially their higher end stuff.
For games you can probably pick any of the 3 monitors. You really have to closely examine the displays to tell much difference. There are plenty of in-depth monitor reviews out there, do a web search and you'll run across them.
Picture quality is primarily dependent on LCD panel technology.
For most gamers, LCD monitors built upon the inexpensive TN panel tech are just fine. The primary issue is viewing angles and color shifting. However, these monitors generally have the faster response times and lower input lag.
MVA/PVA and IPS are more expensive, but suffers from less color shift and have wider viewing angles. Input lag is generally a little higher than TN panels, can also be significantly higher. For example, my Asus VK246H monitor uses a TN panel and has input lag of 2ms which is considered very low for a TN panel monitor. My Planar PX2611W has input lag of less than 8ms which is considered pretty low for a H-IPS panel monitor. My NEC LCD2690WUXi has an input lag of 32ms due to the fact that the internal electronics does some image processing before the image is displayed on the screen to improve image quality; this is considered average for a LCD monitor. 16ms of input lag = 1 frame.
e-IPS panels are inexpensive versions of IPS panel tech. And fills the gap between TN panel tech and traditional IPS panel tech.
See my post in the following thread which contains screenshots of LCD viewing angle examples:
