I was just wondering if its more worth getting an led screen over Lcd. If not is there like anyway to tell between crapy lcd screens and good lcds? Cause some have 1,000,000:1 and some have 10,000:1 but they look basically the same. Thanks!
Due to the fact that all LED backlit LCD monitors are edge lit instead of having a full backlight array the backlight will not be as evenly distributed as traditional florescent backlit LCD monitors.
LED by default does not produce better white than florescent; however they do reach their optimal "white point" sooner than florescent backlight since florescent needs a little time to "warm up".
LED backlight can last longer than florescent backlight; however I've been using my Planar PX191 continuously from 2002 to 2009 for on average 6 - 7 hours per day.
Dynamic contrast ratios are those outrageous 10:000:1 thru something like 2,000,000:1 is basically crap. It is batter to look at static contrast ratio which is typically from 700:1 to 1000:1.
The difference between bad and good LCD depends on your own point of view. For me the difference between good and crap LCD is color accuracy and viewing angles. Monitors built around TN panels like what the OP is looking at is crap in my opinion, They have poor color reproduction and poor viewing angles compare to higher end PVA/MVA and IPS monitors.
PVA/MVA and IPS costs more than TN panel monitors due to higher quality. However, TN panel monitors are geared towards the average user to is looking for the best bang for the buck and don't really that there are better quality monitors which can cost a lot more depending on how higher the "food chain" you want to go.
jaguarskx is correct, it's pretty much the same thing, LED and standard florecent (LCD), as they are both 'backlit' and not distributed throughout. But one LED that I've been looking at is new the BenQ V series, it comes in 24 and 22 inch sizes. They are extremely thin and offer Full HD resolution. I'm waiting anxiously for these to hit the markets!
When I look at monitors I pay attention to a few things. Viewing angles don't matter to me because they don't affect me, I think standard TN panels produce colors for me to accept, once again it really is based on preference. But yeah the main things I look for are:
Aspect Ratio (16:9, 16:10, 4:3, so on)
Response time (5ms, 2ms, etc)
Connectivity (audio in/out, D-sub/DVI/HDMI, USB, etc)
And most importantly, price = )
