Invalid Format on TV when i connect my HP Laptop with HDMI Cable

[ShiKoKa]

Yesterday after my laptop has updated and I've restarted it, I connected it to the TV with the HDMI cable, the Invalid Format comes out.  What might be the cause and how to prevent it from happening?

I've connected with my friend's Laptop and with his, it's just fine and I set my Laptop Resolution same as his but still, it's not showing on TV.

Anyone to help?

Thank You

I understand you are having issues with the display not working when connected to your HP notebook. Don't worry as I have a few suggestions which should help you resolve this issue.

Have you recently made any software or hardware changes on the PC before the issue started?

Did it happen after a software or Windows update?

Have you tried to connect using different HDMI cable?

When was the last time it worked without these issues? Have you attempted a system restore?

For now please try these steps:

• Right-Click on start button> click device manager> expand display adapters>then select the display drivers that are listed and right-click on it and uninstall the drivers.

Thank you Mr. Jeet Singh for your help and you've asked about my PC's Model and it's HP 15AY105.

Well, i did a HDMI Troubleshooting but didn't help and i've tried with a different HDMI cable on my TV & on my friend's TV but still it's bringing on the Invalid Format message and with my friend's PC, it works very well on both of our TVs and with both HDMI cables.

Will try with the Drivers and will let you know how it went.

Thank you again

Good Day Mr. Sigh

Well, I've performed all and as per sequence as the instructions but until now, I still have a problem. 

After I have performed as required, I connected my Laptop to different screens with different HDMI cables but still, Invalid Format message keeps on coming on.

What do you think might be the cause of this and what best solutions might be...?

Thank You for your Help.....
