Does an LCD or plasma computer monitor generate less heat than a CRT monitor?
If the room is 72 degrees when I turn it on in the morning, by the end of the day the room is about 85°. Note: using stand by mode and energy star settings apparently make no difference in the heat output.
Will an LCD put out a lot less heat than a CRT monitor?

It pretty much goes like this
Projector
CRT
Plasma
LCD
OLED - (in development...its gonna be sweet. Google search it)
LCD is not as quick as a CRT - in some you can see Mouse-blur at times, but this is becoming rarer.
Also when you arent using the LCD in its natural resolution (you should be told this when you buy) the image will always tend to be blurry, eg. when using an lcd with a natural resolution of 1280x1024, and then playing a video game in 800x600, the game will look blurrier rather than "Pixelated". Same if you played the game in a higher resolution than Natural.
However those points are moot when you consider the LCD is so much more compact and requires less electricity and generates condsiderably less heat.
Plasma is out of the question for a PC monitor - its application is in large TVs because its Pixels are actually made of small fluroescent/phosphor bulbs which are 5-10 times bigger than an LCD or CRT pixel and thus easilly seen by the naked eye.
(not to mention the phoshor decay really cuts into the displays lifespan)
yes a lcd display will put out much less heat.
CRT's do get pretty hot. Even my 17" LCD gets hot, but not nearly as hot as my last 15" CRT.
An LCD will put out FAR less heat than a CRT monitor simply because of the fact it does not have a cathode ray tube generating all that heat.
LCD's have come down in price - check out what tigerdirect.com, geeks.com, newegg.com have to offer.
