go to sleep from Windows Start menu. Wake up from keyboard/mouse.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
Macbook Air with Win 10 is connected via HDMI to LG 55UH605W TV.
When TV goes to sleep and then switched ON, windows graphics driver screw video playing - plays like 10x or 20x fast forward. Youtube or local files, doesn't matter.
[unplug HDMI cable and video plays normally in macbook screen]
Windows restart helps.
Please fix.

good workaround for you... I am minimalist, don't want another appliance.
BTW, if you have problem with video fast forward only, try this. When you gonna take MacBook off, first open the deck so the MacBook display gets activated. Only after that unplug HDMI and then switch off TV. It seems to be working for me, apart from the sound problem.
I have same partial solution:
After connecting Samsung TV via HDMI, the playback device for sound on Mac Book changes to Samsung TV. I changed it back to Mac book speaker and video started playing on a normal speed. But the sound goes through Mac Book speakers. I connected JBL speakers and it works for me.
Hi Samuel,
We'd like to get additional details about the issue you're experiencing right now with Windows 10 on your MacBook Air, kindly verify the following:
We look forward to your response.
Hi Joanna
* driver is from Nov 16, 2017 provided by Windows Update. If I put there different driver, won't it be updated by another Microsoft update?
* I like this TV and also HDMI cable is the one of highest quality
If Microsoft gets more reports like this, e.g.
perhaps you would like to diagnose the problem by yourself.
I'm happy user of Windows and if Microsoft doesn't have money or people to diagnose the problem, sure I understand it :)
