Whats the best pc to hdmi tv converter?

I'm assuming that since you are asking, your computer has VGA and your TV has HDMI... that will require a converter. (though if you have VGA or HDMI on both the computer and TV, a simple cable can be the solution) Converting the signal is pretty simple... just a converter box. Then you will need a cable long enough to go between the rooms. Wireless options are available, but they are either really expensive or poor quality. VGA cables tend to work better over long distances, but you have to run a separate audio line. Good HDMI cables are usually fine up to 50 feet (longer if you get a repeater).

You don't need a converter to do that.
