I was bored at this site, and started using the scroll funtion of my mouse, and I noticed my screen flickes when I scroll up and down. At first you might think that "why would computer screens need to improve". The answer to that is many things, other than scrolling down a page by clicking with the mouse scroll button. Movies for example, and other related stuff, that can get annoying..
must be a lcd for sure, CRT's dont "ghost" at all ... not even the really REALLY crap ones. Theres nothing you can do about it mate, I have a Dell 19" lcd flat panel and it ghosts (a bit) when Im playing fast paced games ... Ill have to live with it though. But yes you are right, they do need to improve these screens vastly.
