After a recent Windows/Office update my laptop stopped displaying embedded videos when connected to a screen or projector via the HDMI port. It has taken me several frustrating days to find a solution.
So, despite the fact that this post has nothing to do with SEO or Digital Marketing, I just wanted to save you the same grief if you found this page via a Google search.
The problem is likely caused by MS Office changing your default PowerPoint settings after an update. Follow these steps to get the videos playing again on your presentations:
Step 1: In PowerPoint, click on the File menu and then “Options”
Step 2: On the Options menu, select “Advanced” (see image below)
Step 3: On the Advanced Options screen, scroll down until you see “Display” settings
Step 4: In the Display settings section tick the box labelled “Disable Hardware Graphics Acceleration” (see image below)
Step 5: Click OK to confirm
Step 6: Test your video on a second monitor or projector and all should be working fine.
This is a common issue affecting many people. If you know someone using PowerPoint on a regular basis please put them out of their misery by sharing this post.
