I recently bought a Samsung tv and have it hooked to tv cable. to get the hulu/roku/etc, do I have to unhook it from the cable and connect it to a computer?
You can buy a Roku device for Hulu and other services and plug it into one of your TV’s HDMI ports.
I have a Roku box connected to my TV and my internet modem. It works well, but I don’t use it very often. I have always assumed that somebody records the TV channels we watch.
Did it say you could connect to those services on the box? If so connect your TV to your WiFi or Ethernet. If your TV doesn’t directly support those services, the are inexpensive Roku model you plug directly to your TV.
