The SINGLE MOST IMPORTANT factor in LCD image quality is the
panel type. In order of best to worst of common panels:
IPS panels such as S-IPS and H-IPS
VA panels such as S-PVA and MVA
<<pile of ****>>
TN film panels
These days you usually see IPS and TN film. Almost every monitor you see advertised on sale these days is TN film, and I can guarantee the image quality will suck, no matter how many good reviews it has on Newegg. It isn't even a matter of using it for gaming vs photo editing or being some videophile elitist. If you show an IPS and TN panel next to each other to any human being with eyes, they will pick the IPS panel every time.
That being said, IPS is much more expensive. In my opinion, totally worth it. But if you just need SOME monitor now and don't care if it's perfect, TN film panels are a better option. If this is just a luxury improvement, you are FAR better off saving for an IPS panel. Since many manufacturers don't list panel type in the specs, you can tell if it's NOT a TN film because it will have a crazy huge viewing angle. IPS and VA panels are usually no less than 176 horizontal/vertical. TN film is around 160 for the best of them.
Traditionally, TN film has been better for gaming because of lower response times. But these days you see IPS panels with less than 10 ms response time, which is more than enough. ALL LCD panels have SOME ghosting, it should just be as low as possible. I have two Dell 2007FPs that have 16 ms response time, but after a few hours of first use I didn't notice the ghosting any more.
Also make sure to research input lag. Many LCDs regardless of panel type have horrendous input lag, like upwards of 125ms. That means, on the worst of them, there is upwards of 125ms of a delay between when the signal is sent to the monitor and when the picture is displayed. Horrible for gaming.
