You made quite a few assumptions that were not true.
17 inch panel monitors sell at Costco for as low as 350 dollars and I have
seen the cheaper at Tigerdirect.
A 19 inch monitor is closer to 200 or more watts.
They are generally rated at about 250 watts
I do not live in the tennesee valley and do not pay 9.2 cents per killowhat
hour.
I pay about 26.2 cents per kilowatt hour plus tax.
My 17 inch panel monitor has a 40 watt supply and it runs cool so I assume
the monitor is using a lot less than 40 watts unless the screen is a bright
white and I do not run it at full brightness.
I would assume it uses closer to 10 watts with a blue , but not full
brightness desk top.( Just one color on verses all three)
Now the final insult.
When you want to get rid of your tube monitor, better not just dump it in
the garbage.
You might find a citation on your door if you do.
What you do with it, and you can not donate it as no one seems to want them,
is drive (at least for me) about 90 miles to a hazardous waste site and pay
them to take it off your hands.
Of course you can do what ssome city inspector told me to do with it.
Leave it in an alley and some one will surely steal it.
But I tried that with an obsolete portable computer and I got all sorts of
calls telling me I had forgotten it some wheres, please come and pick it up.
No flat pannels are a lot cheaper now and I guess that is why they now
outsell tube monitors.
Take a course in accounting and
Put those figures in your calculator.
YOu remind me of my son when I used to tell him it cost 50 cents a mile to
drive a car he used to laugh at me.
Now he is an accountant he tells that I am not figuring in all the expenses
and it costs even more.
I just bought a new set of premioum 85000 mile tires for $400.
I will be lucky to get 10,000 miles out of them so that by next winter at
the start of the season I will buy a new set and have fresh treads for the
winter.
Thats 4 cents a mile just for tires.
I get great milage driving down the mountain.
But pretty lousy driving up the mountain.

Tube monitors use about 150 watts.
Flat panel monitors of about 17 inches use about 40 watts.
If you live in a high electric cost area, as I do, a flat panel will pay
for itself very quickly.

Hmmm, I ran a few numbers to see how long it would take me to recoup the
additional cost of an LCD vs. a CRT monitor. I think I screwed up my
calculations! Using this data:
19" CRT Monitor, 150W, $200 [15 inch ones use about 150 watts . !9 inch
ones are labled at about 250 watts][you neglect disposal costs]
17" LCD Monitor, 40W, $500 [ Now cost about 350 or less.]
Cost per kWh = $0.092 [try 26.2 cents plus tax when you have it.]
Used for 3hrs a day at full power.
$300 (difference in purchase price) / $0.03 (difference in cost to operate
per day) = 9,881.42 Days. [Try $1.50 a day to operate a tube for 24
hours per day and it does not drop much when it goes into suspension if you
want a quick on. It cost more to keep; the filaments on than you are
figureing.
So where did I screw up? [every wheres]
Or will it really take me 27.07 years to pay for
the difference in initial purchase price?
The numbers used to calculate were not rounded off, but done so here for the
sake of simplicity.
