Windows 7: Laptop not detecting my TV through HDMI cable anymore

Laptop not detecting my TV through HDMI cable anymore

So I've gone blue in the face for the past 2 days trying to figure out what's been going on with my HDMI port. 2 nights ago I was watching a movie through my Dell Inspiron N5050 laptop through my Panasonic HDTV. Yesterday, I tried to connect my HDMI cable to my laptop and computer, but nothing happened...So frantically I've been searching everywhere and trying what I have so far with no progress...

1.System Restore to earlier date when my HDMI port was working.
2.Toggle Computer/Duplicate/Extended/Projector Only and nothing worked(Also made sure tv was on the right HDMI input)
3.Tried 3 different HDMI cables and HDMI inputs
4.Uninstalled all sound drivers and Display Adapter(Intel(R) HD Graphics Family
5.Contacted Dell and had them try to reinstall drivers
6. Checked BIOS but I couldn't find any enable/disable feature for video.
7. Took battery out of laptop waited for 30 seconds pressed power button to reset.

Anything else you want me to try? I don't know why it would stop working for no reason. My Panasonic TV doesn't even show up under my playback devices and when I try and do a dual screen through screen resolution it says another display not connected. I'ved tried going Intel HD Graphics Control Panel as well...no such Luck! Beginning to think that my HDMI port on my laptop is broken. Please any other options?

You say you think the HDMI on your laptop is broken, but also that you tried your computer with the TV as well?

And first thing to always do when connecting a TV up through HDMI, check your screen resolution. It should be automatically detected and set after the TV and Windows talk to each other, but sometimes communication just breaks down.

And of course... You did select the right HDMI source on your TV, didn't you?

hey Oxymoron02! Yes I checked the HDMI source. My screen resolution on my laptop has never changed.
Sorry for the confusion! But my Laptop is my computer...I only have one.

Do you have any other screens with HDMI, or even a friend or neighbour you could visit to check on this?

I'm trying to rack my brains to remember the Intel Graphics Panel from my old laptop, my new one is AMD so I unfortunately don't have access to the application at the moment.

Yes, do that asap when possible. And test with the TV's 2nd HDMI (if it has 2 inputs).

OP, funny to see this post, as I've got a Panasonic TV with one of the a HDMI inputs gone bad, and initially thought it was a dying laptop. Eliminate the TV as the possible cause before servicing the laptop!

SOLVED !!
I and hundreds of others have been trying to make what should be a simple thing work (HDMI link from PC to TV) with no success. I've read all the posts regarding this problem on this site and dozens of others without anything like a solution - total frustration.

Finally today, when I was packing it in, I reversed the HDMI cables and VOILA! Problem solved!

Hope it works for all of you.
