Connecting a Lenovo Thinkpad via DisplayPort through an adapter to HDMI port on an Acer R221Q Monitor.
Embedded video on a webpage works fine in both Windows 10 and Fedora 27. If I go to full-screen mode, the video plays perfectly well on Windows 10, but on Fedora I get some slight lag between sound and graphics, and the graphics are slightly "not right"! Can anyone suggest how I might get round this annoyance in Fedora?
BTW, Full screen works perfectly well in Fedora just using the laptop monitor...
