Because each computer's resolution is different, in particular, today's widescreen display is more and more widely used, when we use a different display slide show, there may be no full screen ppt problem, sometimes there will be two black blocks, and sometimes may appear left and right two pieces of black. Today's small knitting to teach us to solve this problem.
When entering the PowerPoint2013 projection view, there are two black blocks, so that the PPT can not play full screen.
1. Open PowerPoint2013, we switch to the Design tab, and click the custom slide size option under the slide size group in the Customize group.
2, at this time will pop up a "Slide size" dialog box, we click the Slide size drop-down box to the right button, and then "full screen (16:9)" modified to "full screen (4:3)", click the "OK" button. This is generally based on the screen resolution to set the size of the slide, if the resolution is 1440*900, here set to 16:10, and so on.
3, we now enter the slide show view, you can see, PPT is already full screen display.
Tip: For some reason, the slide size we set is still not going to make the PPT play full screen, so you can undo the previous action and then redefine the size of the slide.
