Laptop connected to Projector - image pixellated?
I have just built an old laptop up for use as a spare and all seemed well - I cross-checked it with another of the same breed and all drivers etc are present.
However, when I hook it up to a projector all images (background, school logo, icons etc) are pixellated.
If I connect it to an external monitor everything is absolutely fine.
I have tried it on two projectors with the same result.
Can anyone explain what is going on here?
It is a old HP Compaq nx 7400 running Windows XP. Resolution is 1024x768 - exactly as it is on the working machine.
