Asus Z53S laptop
Vista Business
All factory standard running all current updates etc
GEForce 8400M G display adapter (running latest driver)

Suddenly tonight the LCD display has become slightly duller than normal and quite pixelated.  It's as if someone has wound down the DPI or I have gone back to looking at an old CRT monitor from the 90's.  Screen size/fonts etc remain normal size as does the size and proportions of any images or opened windows.  Colour is approximately the same just a slight drop in contrast/brightness.

I have had to wind back the resolution to 800x600 so I can see the text to make repairs.

A system restore has made no difference, and the effect is still present when booting into safe mode, and during the start up and shut down windows 'flash' screens.  

I have checked everything I know how to check through the basic desktop settings, through the NVIDIA control panel, and in the Asus 'splendid Utility' settings.  As far as I can see everything is normal.

My 3 year old was doing some gaming earlier (Dora and Elmo) and I fear she has clicked on something she shouldn't have.  I am hoping it is just a setting I have missed and someone can point me in the right direction and I will feel really stupid for missing it!

Alternative I guess is that the display has decided to call it quits.

Any pointers appreciated.

I fear the worst. Thought it may be an idea to ensure backups were done and down it has developed a yellow hue across the whole screen. Full virus scan shows nothing.

A yellow hue sounds more like a hardware issue, like when a monitor vga cable isn't connected properly. Might be the same kind of thing but inside the laptop - the connecting ribbon to the lcd screen might be damaged?

Agree, sounds like a hardware issue - is it the same in POST?

Tried an external monitor at work today...sure nuff worked just perfectly. So its either the connector/cable or the LCD itself. Doubt a 4 year old laptop would be economical to repair, with estimates in the $300 - $400 to fix, so I guess its off shopping this weekend.

whack it on the side a couple of times, I had an old laptop that used to get a pink line down the middle, couple of whacks and it was all good for a while.

And if it does fix it you know you are dealing with a loose connection
