When I try to extend it gives the option to detect, but does not detect the tv.

Ok so I have a TCL Roku TV and I want to extend my display so that the TV is used as a second monitor. When I connect the HDMI cord It mirrors the laptop screen just fine, but it wont discover the tv so I could use each with different things on them. How do I get the Laptop to discover the TV?
