What is the maximum resolution supported by your TV? Is is 1366x768, or is it full HD @ 1920x1080?
If your TV supports a lower frequency that the laptop is set to I have seen circumstances where the mode not supported comes up. Theoretically, it should all be handled automatically, but you could try setting your laptop to a lower resolution then try switching it.
If your TV is a recent model you may also be able to update its firmware, and that might help.
I'd also check your laptop manufacturers website for any known issues.
Edit: On Some laptops, such as the Lenovo's, I think you can popup a menu which allows you to specify settings for the external monitor, including the resolution, which allows you to have one resolution on the laptop and another on the external source. Again, your laptop manual should be able to tell you if it supports this functionality.
