Laptop connects to one TV but not to another - Weird Issue

[R B]

Dear All,

My new laptop (HP - Windows 10) will not connect to my TV (Videocon 40") via HDMI.
Tried different ports, different HDMI Cables.

I remember connecting my old laptop(Toshiba - Windows 7) to this same TV.
Both HDMI ports are tested and currently working fine with TV HD Set-top box.

No doubt regarding laptop settings, as this same HP laptop will connect to another Samsung 20" TV via HDMI.

Where to look for problem? Confused in further troubleshooting...

Thanks in advance...

Hi,

Please do try these troubleshooting steps that may help.
- While the TV is connected to your HP laptop, press the Windows key + P at the same time and select between Extended or Duplicate display.
- If it will not work, do uninstall/reinstall the graphics card driver.
- Go to Device Manager and uninstall the graphics card driver.
- Next is to open Programs and Features then uninstall anything related to the graphics card.
