I have a Dell Inspiron 530s. The graphics card is an ATI Radeon HD 2400 XT, driver R179781 and the screen is a Dell 1908WFP 19".
It was all running perfectly under Windows 7, but after the Windows 10 upgrade, the screen is fuzzy.
This appears to be due to the fact that W10 is using a Basic Display Driver which limits the screen to 1152x864 pixels (it actually has 1440x900). The result is that the screen is squashed into 1152px then STRETCHED to 1440px - so it all looks blurred.
I have tried reinstalling the AMD driver (in compatible mode), but Windows 10 just refuses to see it.
Does anyone have a solution, including recommending a new graphics card (if that's what it takes!).
