[Q] Are all large LCD monitors hot (literally)?

I have a Dell 2407WFP and it's literally hot to the touch. :shocked: It's not hot all over. Most of the surface is warm, but near the top, especially the right side, it's burning up. It's actually 109 degrees Fahrenheit (almost 43 Celsius). The top of the entire backside is also hot.

I felt an Apple 23" Cinema display and it's also warm and hot near the top.

Has anyone else with a large monitor like this noticed that it is hot (or not)?

Kinda off topic, kinda not. Remember, LCD's consume 1/2 as much power as CRTs of the same size, so if you had a CRT w/ 24" visible, it would be a power hog/heat monster. CRTs exhast heat through a much larger area. LCD's, all the heat goes straight up out of the narrow exhast area.
 
The power consumption of 24" and larger LCDs seems to be much higher than that of smaller sizes, almost double what the 22" ones are rated for. They are similar to the 21/22" CRTs, at around 80-100W.

area size is bigger, more back light power needed plus more power to drive the pixels... so it grows kind of exponentially.
 
Another thing is, which has bugged me for quite sometime, but is also understandable, is people consider things hot from the human/biological perspective. Ya know what? NVIDIA says its gfx card can go to 100C, sure thats boiling water for you and me, but thats like 120F to us, hot? yes. Unbearable? Ask the ppl that live in Phoenix. Sure the exhast of (insert comsumer electronic here) is hot to you, but you're carbon based, not silicon based.. You may WANT your 57" LCD or 8950GTXXX to run at 23C, but ya know what, it's not going to, such is life.
 
its hot because of the backlight .

CRTs use a lot more power, but they also have a lot more surface area and vent holes. back lit LED displays are even more hot (there is a $3000 samsung that has LED backlights and it even has to have a fan)


Hopefully OLED comes to our rescue in 3 years.
 
Mine are warm, never really hot to the touch to the point of discomfort. However, I can definitely feel heat coming off my TV (42" LCD). I barely even use my heat in my apt because my computer, computer LCD, and TV are on so often they keep my living room warm enough for my liking.
 
I hajjve a Dell 2407 and it is not hot at all. You can feel some warmth coming from the top but no way you could consider it HOT. You must have a problem.
 
Both my Samsung 245BW's are cool to the touch.

If anything puts out heat it's my 32'' Dell LCD TV. That thing heats up quite a bit, and pretty quickly too.
 
THey have gotten 22" very efficient and those should not get that hot. They drink about 40-50watts. 24" will need almost double that. It would be a lot better when they have LED backlight LCDs as they use a lot less power and produces less heat. Will still take a while though.
 
Once I touched the base of my laptop screen and it was pretty hot to the touch (hot enough to make me move my hand away as a reflex). I think my laptop screen is upside down, too, since the colors only invert when I look at it from the top down.

supposedly LED backlight displays make even more heat
because the backlights arent just at the edges like on a normal ccfl lcd, so the leds in say the center are not easy to cool. so either they will heat up more in the same form factor or the screen will have to be thicker to allow more air space.
