PPT is saved as a picture by default, and the picture saved in 16: 9 format is 1280X720, and the 4: 3 version may be 960X720, which is often not enough. There are not many ways to save HD online, which is more troublesome. According to my experience, there are two simple methods: 1. If the PPT page is rarely saved as a picture, the desktop (the best resolution of the display) is above 1920X 1080, and you can take a screenshot when playing. 2. If you often want to save the page as a picture, sometimes it is troublesome to play a set of PPT screenshots one by one, and the picture saved by default is too small. The solution once and for all is to modify the registry. Open the registry and navigate to.

HKEY _ Current _ User \ Software \ Microsoft \ Office \16.0 \ PowerPoint \ Option

Here, "16.0" corresponds to the version of Office20 16, and others correspond to 20 13, 20 10, 2007, etc.

See if there is an ExportBitmapResolution.

If so, please modify the key value. Otherwise, create a new DWORD value named ExportBitmapResolution under Options. 32-bit or 64-bit values should be consistent with the installed version (this is a guess. If it is invalid, please delete it and rebuild the value of another digit). Right-click to open the editing dialog box, select 10 and fill in the value 128-300. It is said that the maximum value can be 307, which has never been tried. If it is not used for printing, "192" will do.
