Finally swapped out all my CRTs for LCDs.. holy crap. The power savings
my old 24 inch CRT was drawing 240 watts.. the 22 inch wide screen LCD
less than 40.
Now i'm converted over I can run SOOO much longer off the batteries and
hydro.. now the only bummer is gaming. Good GPU's suck the juice.. if
you want kick ass graphics you gotta provide a fair bit of power. Kinda
miss the 24 though.. silicon graphics workstation monitor.. man it looked
I setup a KVM so I can run the monitors off the laptop when im in
conserve mode.. or let the big system rip for bigger projects. What a
time to get a video job huh?
Speaking of video you guys are pretty smart... any advice on rigging
cameras to a crab fishing boat? We're trying to document the dungeness
crab season with a fixed camera looking down on the deck. Thus the need
for the big power hungry CPU for processing at home, and at the same time
we need to have a low power rig for the boat. When in idle we can't run
the fish finder and the comp at the same time.. classic problem with the
scored a few of these 'water proof' cams
to do some action shots while we harvest but i'm dubous about the
quality.. Would love a self contained video capture unit that was water
proof, salt proof and crab proof.
You can check out the boat.. just made this site for us.. still a bit
the tuna videos are pretty basic, we want to run a full seaons of video
during crabbing. Those deadliest catch guys can eat our shorts..
crabbing off a small boat like that in the raging pacific is way more
hairy that those guys
anyway, thats what i've been doing..
You might try rec.video.desktop and ping "Scubajam"
(Jim McGauhey) he can provide some great advice on
this sort of thing.
cheers.. downloading that group now..
knew i'd get some good pointers even being off semi topic -- none the less
ditch your CRTs if you can kids.. those things suck the power bigtime!
Well, assuming your readings are accurate, yours certainly does! ISTM,
that your 24 inch CRT Monitor is taking around a hundred watts more than
one might reasonably expect.
Unfortunately (or perhaps not, since I find the 19 inchers heavy
enough, thank you very much! ;-), I haven't owned one that big, so I
can't offer any 'typical' power consumption figures for that size.
However, I can present some figures for the smaller sizes.
Most 15 inch CRT displays, typically consume around 60 watt, 17 inch
around 70 to 75 watts and 19 inch around the 80 to 90 watt mark.
Extrapolating the 90 watt figure from a 19 inch to a 24 inch tube,
suggests a figure somewhere in the region of 130 to 140 watts is what
might reasonably be expected.
This all assumes a reasonable screen refresh rate of either 75 or 85
Hertz (in this case, well named since the more Hertz, the more it hurts
your electricity bill ;-). The power consumption for any particular
screen resolution increases with higher refresh rates. However, the
maximum refresh rates for the higher resolutions reduces somewhat from
the 150Hz or even higher that some high quality monitors are capable of
at their lower resolution settings.
Doubling up the refresh rate comes nowhere close to doubling power
consumption, so I do have to wonder how your 24 inch monitor manages to
'burn' so much juice. Yours is certainly not typical (even for a 24
incher), and I think you're rather overstating the case for LCD versus
CRT power savings.
Most folk aren't going to see the 200 watt reduction that you're
getting, more likely 30 to 50 watts at most out of a system total that
might be in the two to three hundred watt region. Obviously, in the
context of this NG, where power consumption is a high priority, there is
a case to "Upgrade" from CRT (a mature technolgy with over a century of
development behind it) to the newer (but relatively immature) technology
of LCD flat panel displays.
For those of us (the majority) where colour rendition accuracy is not a
high priority, the "upgrade" to a flat panel LCD display when the
current CRT is showing its age (or has failed) makes a lot of sense if
the limitations of LCD are accepted (not the least of which, quite
often, it's the only affordable choice). Be careful, especially when
replacing a large CRT with an equally large LCD panel, that you're not
going to be _increasing_ your power consumption.
An effective way to reduce power consumption by your display (whatever
the technology) is to disable any screensavers and use the power
settings to power down the display after a reasonable period (say 20 to
30 minutes). This is especially important for backlit technology such as
an LCD panel where the classic 'screensaver' does anything but!
