Weird problem with my new laptop. Quite often, website banners/picture display in a very blocky low resolution. For example; the OcUK banner at the top left will be noticeably lower res and you can see the border around the OcUK sign. Also on Facebook, my profile picture and pictures in general look awful - like so.
The really odd thing is for the OcUK banner - it doesn't always do it. Completely random when it appears low-res. I am assuming this is a Windows problem (or possibly the screen). It is a brand new laptop with the following specs;
Acer 5738Z
15.6" HD LCD Screen
Windows 7
Dual Core
3GB RAM
This issue only occurs on websites, the screen with Windows navigating, videos etc looks crisp. Any ideas?
