This depends on your laptop output. Most new televisions will have a “PC IN” or a “VGA IN” input, if your laptop has a “TV Out” or “VGA Out”, you can connect it to your TV. The quality of the TV channel will be almost the same as normal TV. Note that you may need extra hardware or a “Sound In” connection on your TV to send the sound to the TV or you can just use your laptop speakers or connect your laptop to a HIFI.
