Fix+a+Faulty+Monitor+Resolution

If you turn your PC on without your monitor being turned on, you may find that Windows 7 does not properly detect the monitor settings, and when you do come to switch the screen on, it is using the most basic settings possible, with a low screen resolution. This makes it difficult to see what is on the screen, but you do not need to completely re-boot your system to fix the problem. Simply force Windows to re-scan your system and detect the monitor properly:-
 * Fix a Faulty Monitor Resolution**


 * 1) Right-click on a blank area of the desktop and choose **Screen resolution**.
 * 2) Click the **Detect** button.
 * 3) Windows will detect the new monitor and apply what it thinks is the best screen resolution. You can change this manually using the **Resolution** drop-down list.
 * 4) Click **OK** to save the settings.
