I recently got a new LG TV and also an LG Blu ray home theater system (39LN5400 and BH4030S, respectively). The BH4030S has SmartTV functionality, however, it requires a wired connection and the nearest jackpoint is across the other side of the room. According to LG customer service, a wireless adapter will not work on either the TV or player.

Apparently there's some kind of cable I could run across the room. However, I'm loath to do this, because it would look ugly, and this place is rented out as a holiday house occasionally. Are there any reasonably cheap, discrete ways to get internet functionality to the TV?

Failing that, I'd like to be able to view internet material indirectly, for instance by having Youtube videos from a phone or laptop displayed on the TV.  I think you can do this with a HDMI cable, but my laptop doesn't have an HDMI port.
