My 30 inch is like a small heater, I'm glad I never ran it with my PowerMac because then my room would be in a constant state of equatorial weather.
If LED displays put out zero heat, then I will become even more inclined to ditch this 30 for a pair of 24's and a Sewell DisplayLink adapter for my MacBook.

Assuming you are not talking about an OLED 30" display because those are not in production yet, LED backlit use about 30% less power than a standard LCD.

I switch from a 40"lcd tv to a 55" led lcd tv. The 40" would give off a lot of heat the 55" gives off none. I hope they start shipping bigger led lcd computer monitors.

I would have thought most of the heat comes from the power supply, since the heat comes out of one side, or the other. I suppose the led's might require a smaller power supply though, so maybe that's the deal. kj.
