We use Miracast in the office to connect to the Tvs in the conference rooms. I used it for months without issue and then a few weeks ago it stopeed working for no good reason.

The display would say I was actually connected – and it would not come up on the TV. Eventually it would just die and tell me I had a problem.

After a considerable amount of trial and error it turned out to be the intel display adapter driver….ok then. Figured I should share.

• Right click on the desktop
• Display settings
• Find display adapter properties

 

• Properties
• Update Driver

 

And after that and a reboot – Miracast back and working !!!
