I have a viewsonic 1912wb monitor, got it from newegg, it is 19 inch widescreen, in my opinion widescreen is the future and I love having the extra space on the sides for surfing the internet and for editing videos and playing games
the resolution of my monitor is 1440 x 900 which is a 19:10 ratio
IT is a little narrow on the tops and bottons because of its resolution and size, the larger widescreen LCDs do not have this problem, because they have more resolution, but they are also much more expensive, a 21 inch widescreen lcd can cost from 600-800 dollars, my 19 inch widescreen cost 300 dollars which is cheaper than some 19 inch 4:3 monitors, its a great value and I expect to still be using this monitor for a long time, it has no ghosting, a little blacklight bleed, but that is normal with all LCDs
if you are going LCD I highly suggest widescreen because it make interacting with windows a less stressfull and more natural experience, having a widescreen monitor does require a little extra work if you want to play older games on it that were not designed for widescreen, most games it is easy to change a setting or whatever to make them work widescreen
an excelent resource for widescreen gamers is
www.widescreengamingforum.com they have solutions to make most pc games run widescreen, almost all the new pc games have widescreen support built in so you wont have to worry about newer games
also you need to think about resolution, LCD montitors look much sharper at their native resolution, they become much more fuzzy when you lower their resoluition, this means in order to get the most out of your monitor in video games you need a video card that can play games at that resolution, I have a 6800GT which is over a year old, its still a great card but the newest games are certainly starting to strain it more. it runs all my games great at 1440 x 900 right now so I am very happy with it, I if you do not want to upgrade your video card right now and you play alot of games you may want to consider getting a lower resolution LCD for right now until you can upgrade the both together. if you do not do alot of gaming or do not mind running the monitor at lower than its native resolution then get as high resolution of a monitor as you can afford
I originally bought the HP 21 inch widescreen LCD but discoverd it has a slight delay in it screen which makes it impossible to use in my opinion so I returned it and got a smaller lower resolution viewsonic and I am very happy with it right now
if you are looking to save money and have to have a huge LCD then I think large 4:3 LCDS will cost less than 16:9 or 16:10 LCDS, in my opinion the extra cost is more than worth it, and the smaller LCDS there is almost no difference in price
ok, I think I gave you tons of info so now u can search for yourself and decide what you want
www.newegg.com is an awsome site
