Solutions to incomplete display of Win7 computer connected to TV

When the computer is connected to the TV, there is a problem of incomplete display, you can try to adjust the computer's display settings to solve it.

[windows][Original]qttools reinstalled after uninstallation prompts this extension has been installed to all applicable products

This method is suitable for VS2019 and has been tested and effective. Recently, for some reason, I always crashed when using QtVSTools to open QT .pro file and could not load the project normally.
