my screen turning white (I can still see things but looks incredibly faded) help

my screen (on desktop , including when I use the internet) is beginning to fade significantly, it's beginning to look very pale and whitish.

does this mean i need a new monitor? is there something i can do? if so, please give VERY SPECIFIC directions, as I am a stupid newbie! windows 7)

thanks

if i need to get a new monitor (I have a soyo 24 inch now) what is a cheap but good one for games in particular? I need 24 inch or slightly bigger

ok i adjusted the light on the monitor and it seems to be working (strangely though it often starts out looking fine for a couple hours, then it fades to white--does this mean i need a new monitor?)

what's weird is that while i was adjusting buttons on the monitor, i now have a large very clear square on the upper right of the screen--it can't get it back to match the rest of the screen. please help, i feel like such a jerk

The best possible way to know if you need a new monitor now that you have messed with the settings and it still happens is to use a different monitor to test it. If you don't have another monitor you should look on the back of a TV for a compatible plug and see if that works. You probably have a compatible plug if you have a newish TV.
