CRT power consumption
Lynne Hately
consumption of CRT displays when they are blank, as opposed to when
they are filled with text/graphics. I often turn my computer on and
off three or four times a day and I think that this must be hard on
the monitor. I would like to leave the monitor on all day with a dark
screen but am concerned that this will waste a lot of electricity. The
monitor is rated at 85 watts. Not a huge amount but it adds up. Any
help would be appreciated.

I've got a UPS that can display "% Load". When I blank my Mac's monitors,
the % load goes from 60% to 55%. The two monitors (Sony CPD-1304s) each use
about 150 watts and the Mac about a 100. 400 Watts = 60% load, so 667 Watts
= 100% load, 5% of 667 = 33 Watts, divide by 2 monitors = approximately 17
watts difference in unblanked vrsus blanked monitors.

Look in the April 26 issue of PC Magazine, page 114. The run and
standby power for 28 monitors is listed. Some samples;
Acer run 52W standby .5W
IBM PS1 83W 20W
The numbers vary all over the place so there is no general
rule that I can see.
If you want to know how a particular monitor performs you will
need to measure it.
