how long would it take for a 19" (or 17") LCD to pay itself off?

Any estimations? They consume a lot less power, correct? Maybe that could be a good excuse for me to get one down the road? Does anyone know enough about wattage etc to try and calculate this? I can tell you how much electric costs in my area if you like...
 
Take how many watts your LCD uses and multiply by how many hours per month you use it. Do the same with your CRT. This gives you two watt-hour numbers. Divide those by 1000 to get KWH numbers.

Now, find out how much your power company charges you per kilowatt hour. Multiply that amount by your CRT Kwatt-hour number and your LCD Kwatt-hour number. That's how much it costs to run each display per month.

Subtract your LCD cost from your CRT cost. That's your monthly cost difference. Divide your LCD cost by that number. That's the number of months that it will take for your LCD to pay for itself.

What he said.
 
FOREVER

i got a LCD b/c its much easier on the eyes. NOt getting the CRT induced headaches (even when the refresh is set at 100hz) made it well worth it
 
Actually don't forget to take into account the heat a crt generates. If you live in a warm climate then the heat from a crt means more work for the a/c. Also, at least in my opinion, LCD's are easier on the eyes.
 
huh? i didnt take any considerations to that when i bought my 20.1in lcd dell 🙂 🙂

but if it does save alot of power good news for me 🙂 haha
 
My 23" lcd probably doesn't use much less power then my 19" crt.

I'd love to get the 30" mac but no way am I going to spend more for a graphics card to just POWER THE DAM SCREEN!

Hmmm..maybe when I the price of the graphics card drops down and the screen...

Can't imagine 4mp for a screen res! Must be AMAZING to have 🙂

It would take infinite time to pay itself off due to lack of adjustable resolution and craptacular colour count not to mention soreness of the eye. Sorry, LCD suck 😛

Studies have been done, not soon enough to justify the cost, and the fact LCD power consumption is going up and not down does not help.

EDIT : There are plenty of good reasons to buy an LCD, don't get me wrong (my 2001fp is a lifesaver in a dorm, I actuially have deskspace with it!) but power is not one of them.
