My TV is not detected when I coect to my laptop through Thunderbolt/HDMI cable

I have a laptop with Thunderbolt(Mini Display Port) and ofcourse TV has HDMI port. Si I bought a Thunderbolt to HDMI cable and coected the devices but TV is just not showing up when I press Detect.

Now, this laptop is not having any issues when I coect it with my exteal monitor, its just the TV which is not being detected.

• My laptop is a Lenovo Windows 10
• TV is Samsung LCD 1080p

Any suggestions?
