The thing is ....most tv's are not packaged and set up to operate from 12v , not any more,
And dedicated video monitors wired for 12v are automotive entertainment style, available in size upto 14", but only have RCA a/v input, not PC or HDMI
Search the truck stops and marine supply house to find specialized
12v equipment
BTW... A 15" laptop will use two Or three times the amount of power as a 15"
Tv
A new TV powered by inverter will use less power than the same size display laptop running from 12v
Buying a tv that uses a 12v power brick is going to be the best option, for dc only use
