If you’ve changed your screen resolution and the screen went black and stayed black, there is hope! When you change your resolution in Windows, you’ll be asked to confirm the change by clicking Yes. The theory is: if you can’t see the confirmation, you wont click Yes. However, if you hit Enter, or something crazy (but computers aren’t crazy…) goes wrong, you’ll be left with a black screen. A black screen has it’s uses: a mirror, an oversize paperweight, a doorstop etc. However, if you’re not satisfied with your new-found paperweight, follow this guide.
