W7 display settings now bad?

[Mark M]

Just switched my Win7 PC on and the display has turned rubbish with no taskbar preview (when you hover over one of the icons it just has the name of what ever it is rather than it flashing up with a little thumbnail) and everything seems to be low resolution?

Ive had a look for some settings to change but cant see anything obvious.

Any ideas?

Right click the desktop. You have two options, "Resolution" and "Personalise".

Go to resolution and make sure it's set to your monitor's native resution, eg 1920x1200, 1680x1050 etc.

Then go to personalise and make sure you have an "Aero" theme selected.
