If you want to connect the computer to the television, most of what comes on the screen is something that can be shown on the television. This configuration would make the television act as a monitor (HDMI or PC cable required). In those instances, it would work.
Hulu is not supported officially on 2009 Samsung products, and the wireless dongle is for connecting your computer with PC Share Manager and wirelessly streaming video from your computer to the TV using that interface.
Not just "any USB wireless device" will work, although few on the market have been reported as working. Samsung can offer telephone support for the Samsung WIS09ABGN Linkstick only. Most 3rd party adapters will not work.
Does that help?
I have tried to read a lot of posts about this, but I don't think I have the full answer. If I hook up my Samsung LED tv to my home network, can I stream video from Hulu? Or do I need a PC with PlayOn on something similar installed and connect my TV to the PC?
Also, can I just use a basic USB wireless adapter to connect my Samsung TV to my home network?
