Does an LCD or plasma computer monitor generate less heat than a CRT monitor?

Question

I have a 16" CRT monitor and it it seems to generate an insane amount of heat. I can feel a lot of heat radiating when I hold my hand over the rear end of it. (The PC tower puts out less heat than the monitor does) I have also tested this by keeping a thermometer in the room. For every one hour the monitor runs, the room temp goes up one degree Fahrenheit.

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?

Answer 1

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)

Answer 2

lcd video show gadgets or lcd video show gadgets are changing the old CRT or Cathode Ray Tube displays and are a good distance more desirable in a large majority of purposes. There are countless advantages of lcd video show gadgets over the old CRT reflects. on an identical time as lcd video show gadgets are compact and lightweight and eat much less means approximately 20W while the CRT video show gadgets are cumbersome and heavy ingesting upto 150W. An lcd video show produces completely sharp photographs with appropriate image geometry while in CRT the sharpness is constrained and it has a tendency to blur greater at extreme brightness and with the growing to be old of the tubes and suffers from geometric distortions. lcd video show gadgets have a relentless tonal scale and can show text textile with wonderful evaluation while the CRT video show gadgets show stable marvelous aspects which will reason different areas of the image to dim and likewise has undesirable text textile evaluation using fact of constrained bandwidth. lcd video show gadgets do no longer in many cases flicker while a faint flicker can continually be stated in a CRT video show.

Answer 3

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.

Answer 4

CRT's do get pretty hot. Even my 17" LCD gets hot, but not nearly as hot as my last 15" CRT.

Answer 5

yes a lcd display will put out much less heat.
