As that thread points out....get a normal TV, one that has a converter brick in the power cord....look at the info on the converter or the TV owners manual to make sure it is converting to 12V (most are). Then buy a 12V power cord for the TV and you don't need an inverter. Modern TV's, and computers, run on DC. When you plug them into a 100V outlet there is either a brick in the cord or inside the TV that converts the AC to DC. If they are using 12V DC you can run them right off the battery and save a bit of power and quite a bit of $.
