Thank you for kindly reply,
But the menu still small even I select the font size and the zoom option.
Could you tell me another solution, please？

Further Explanation

System: MSI GS65 8RE
Browser:chrome version 67.0.3396.99 (x64 )

Please help see the RED circled four corners, the menu is too small to use.
At first time it runs well, but when I click some options it goes wrong...
