Summarize the following:
Outdated video and graphics drivers can definitely cause issues with your display. If fixing the refresh rate and resolution didn’t help, update your drivers. Visit the manufacturer’s website for your computer or monitor and search for video and graphic updates for your particular model. The power settings tell the computer when to turn the display off after a period of inactivity and when to put the monitor to sleep, and they control the brightness based on certain factors. To reset to the original settings, go to Control Panel > All Control Panel Items > Power Options > Change Plan Settings > Restore Default Settings. Select Save Changes. This function, which is available on certain computers with Intel processors, is designed to reduce energy consumption by optimizing the picture contrast. Unfortunately, it can sometimes cause issues with the display, and turning it off may fix your problem.  From the Start menu, select Search, and look for “HD Graphics Control Panel.” Click Power > On Battery, and under Display Power Saving Technology, click disable. Click Apply, then OK, and then restart your computer.
Update your drivers. Restore default power settings. Disable Intel Power Saving Technology.
