You have to use your imagination to understand what this means. Anything online from an addressable website can be seen, full-screen, on my TV. YouTube stuff, Hulu, network holdbacks...whatever I can catch on a PC, I can see on my LCD TV. Full screen.
I plug my little Asus online netbook into the back of my TV, screen output into screen input, and there ya go. Treats the output as another monitor.
The cable cost $25 at BestBuy. I had a wireless mouse onhand that lets me scroll thru whatever shows up on the screen after I rewrite the file. I might install a wireless keyboard...
I was gonna use an HDMI cable, but I ran out of space on the TV inputs.
