Windows 10: HDMI not working after upgrading to windows 10

My laptop has a broken screen and i use HDMI to connect it to TV screen. i upgraded to windows 10 and now i cant switch screens again, tried Win + P and it doesnt work, i think im in middle of upgrade because i can barely see little blue window on top of my screen and it needs me to maybe accept something or tick some box or idk picture below but i cant do that because i cant see anything, so is there any way, i can change my display monitor without being able to see screen?

Hdmi sound not working

Hi Peter,

One possible reason why the HDMI sound does not work is due to the conflicts with the playback settings. For us to help you make the HDMI sound to work, we suggest that you answer the following questions for further research:

• Have you made any recent changes to your computer?
• What is the current build and version of your Windows 10?
• Have you tried to download and install the most updated sound and display driver of your computer?

Meanwhile, we suggest that you perform the steps on this
article as our initial troubleshooting and see if there will be any changes on the HDMI sound.

We'll be waiting for your response.

 

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

 

No HDMI Sound after upgrade to Windows 10

Followed all procedures suggested, and all my drivers indicate they are all up-to-date! There is no HDMI sound to my Samsung TV following my Windows 10 upgrades. I am running Dell XPS i7. There currently is no resolve to this issue. **ALSO NOTE: My Samsung
TV does not show up on the 'available devices' list? Are there possibly 'updates' now required for the TV itself? Hmmm, tr
