The internal screen keeps flashing when I tries to connect to a wireless display while the wireless display shows nothing. It only happens when I choose "Duplicate" or "Extend" in the project menu for the wireless screen. It seems to be a bug in driver because the function works fine before I use Lenovo Vantage to update drivers (but I have to use the newest graphic driver to correctly load color setting). I already tried two different wireless displays (one Samsung TV and one windows PC). And reinstalling os (both windows 1803 and 1809) also can not solve the problem.
Current OS: Windows 10 1809 17763.168
Graphics Driver: 22.214.171.12423

Hi Heyuhang0! Welcome to our forums community. Have you tried connecting your laptop to other devices? If yes, try to rollback the driver version. The instruction is here: https://www.intel.com/content/www/us/en/support/articles/000008628/graphics-drivers.html. Let us know how it goes.
