There are two ideal choices when connecting to a TV, one may be a better choice depending on how large it is. HDMI (or DVI if your TV is a bit older), or VGA (standard monitor connection).
You would use either of those, depending on the connections your laptop has. Plug in your TV as if it were a monitor. Depending on the Operating System your running on your computer, enabling the monitor may be different. But what you want to do, is change the “input” or “source” of the TV to whatever connection you just made in the back of the TV (HDMI1, HDMI2, VGA, PC) whatever the TV has it labeled as.
Once you have the TV source switched to the new mode, you should be able to enable the monitor, and adjust the resolution accordingly. If the TV is 1080P, the resolution will be 1920×1080. If your TV is 720P, the resolution will be 1366×768.
You should now have the TV on the right mode, and it should show the desktop picture of whatever your computer had. Now simply bring up the browser for Hulu, or whatever, and you can click and drag that window into the TV (which is now being used as an extended desk space). Act as though you’re trying to drag the window out of the way of your laptop, and into the other screen.
You can change the positioning of the TV to match where it is physically in orientation to the laptop. So, if the laptop is directly in front of the TV and both screens are facing you. You should be able to click the second display under the adjustment menu, and drag it directly above the laptop screen.
I have experience setting up Linux, Mac, and Windows machines as a media box for a TV, so if you have any other questions about setting it up, or you get kinked up along the way, and don’t know which cables to use, send me a PM.
