    I have a Dell 24" UltraSharp 2407WFP LCD monitor that I've owned for at least 4 years, probably more like 5. This sucker can put out some heat, and power draw at max brightness is ~ 60W!!!

    Is this typical? Newer LCD monitors are any better? Clearly it's a CFL, and LED would probably be better, but by how much? It's probably on average 6 hours a day. Over the course of a year that's ~ 2200 Whrs, which I guess isn't expensive, at most a couple bucks a month, but it just seems so excessive.

    Cnet usually publishes power consumption in their reviews.

    For example Dell G2410 consumes 25 watt at max brightness.

    The comparison isn't really fair because (besides the different backlight) the display you have is far superior (IPS/SIPS/PVA/SPVA displays consume more power than 'inferior' TN panels).

    I'm guessing a couple of bucks a year ;)

    Here are more measurements: http://nl.hardware.info/productinfo/benchmarks/8/monitoren?products[]=96137&specId=3895

    PS. you probably already know but another way of saving power is putting your display at lower brightness. I have a 25.5" TN display that consumes ~ 24 watt a lower brightness.

    Thanks, yeah I did drop brightness, and at lowest brightness it consumes about 45W, so not a huge savings. I drop it about 20% because after that it just feels like I don't get the contrast I need, even after toying with settings. But that 20% down reduces it 5W, so something I'll live with.

    Good info though, thanks +1.

    LOL, even if it was on 24/7, it would still be an insignificant amount. A few dollars a month for 24 hours operation at worst.
    That depends on what you mean by "better?" There are pros and cons to both.
    Heat is very much an issue. Cost to operate is not.

    I did my math wrong. 6 hrs x 60W x 365 days = 131400 Whrs or 131.4 kWhrs ~ $0.20/kWhr ~ $2.20 / mo.

    In any case still insignificant.
