Windows 10: HDMI problem after installing Win 10

I have 2 regular monitors connected via DVI, and a TV which i connect via HDMI.
In Windows 7 when i connected the TV one monitor automatically shut off and the other one duplicated onto the TV.

Now in Windows 10 my TV wont receive any signals except when im booting up.

When i try to change it in displays settings to use the TV and one monitor it automatically reverts back to the two monitors.

Latest GPU drivers installed. Am i missing something?

Second monitor doesn't work

Hello dear Manager of Microsoft

After installing Win 10 I unable to display to a VGA projector or even I am unable to connect my laptop
to TV with HDMI cable.

Before that I had win 8 and I had no problem, after installing win 10 this problem appear.

I updated the windows. I updated the Graphic card, I do all setting but when I connect HDMI I can't duplicate my monitor, when I click winkey+p the duplicate dosn't work and the TV shows no signal.

Please help me, I am a university lecturer and I need to connect my PC to projector, If i can't solve this problem I should uninstall win 10!!

 

Missing HDMI sound after Windows 10 Fall Update

My problem were kind of similar.

After installing the latest updates on windows 10 pro, audio on the one and only AV-device, HDMI TV in my living room died.

Hardware:

Dell OPTIPLEX-780 and ATI RADEON HD 4xxxx series graphics card.

The ATI GC is not supported with a WIN 10 driver but everything worked until updating win.

and the DIGITAL AUDIO (HDMI) appeared to be disconnected even though I knew this not to be true.

After trying all of the above my soulunion were to install the last available driver (WIN 8)

Running the driver - install .exe in winddows 8 compatibility mode and updating the driver through DEVICE MANAGER. (choosing from the installed driver)

Bets regards Jeff
