Hey guys, been having a problem here for the last little while that's really been messing me up.
I have an Acer Aspire V5 laptop with a Radeon HD8450G integrated graphics card installed in it and I've been experiencing some issues when I go to connect to any TV via HDMI.
This is the second time this has happened to me, the first time a Microsoft support tech was able to help me ( We had to delete or change some values in the registry ) but I can't seem to remember exactly what values we changed. I'm not sure if its the same problem but the story goes like this: (I also might add that I have just about exhausted every other option i.e: Roll back drivers, re-install drivers, win + P, tried different tv's and cables - All of that has been tried and to no avail.)
I was currently using my TV in my bedroom as a monitor due my laptop screen being horribly cracked, it operated flawlessly, no errors, nothing. I then decided to go and hook up to the TV in my living room one day, did that and again it worked great.
It was after then that I switched back to my first TV which out of nowhere stopped working, HDMI port just won't be detected and the TV show's a "no signal" bubble. Damages to the port and cord are highly unlikely, I'm very gentle with my electronics and I didn't move the laptop very far. I really hope someone can help sort this problem out as I am just beside myself with frustration and confusion, I spent 3 hours last night on Microsoft answer desk with 2 different techs who told me stuff I already know. It's almost as if the HDMI port literally dissappeared off of the moterboard, and there should be no way that happened.
HMDI WONT WORK HALPPPPP.
1.In normal situation you don't need to modify registry. i presume, that OS reinstallation is almost unavoidable
2.Show me what you have in device manager>sound devices
3.Meanwhile execute this operation: sfc /scannow https://support.microsoft.com/en-us/kb/929833
And for win8.1/win10 this command too (executed by same way): DISM /Online /Cleanup-Image /RestoreHealth
4.Try to boot up from Live CD (portable OS) and check HDMI connection
