    Hello all new owner of a xps m1530 here....
    2.5gig 9300
    200gig HD
    3g ram
    8600gt
    LG 1680x1050
    ($1230 after $599 off and 26% off EPP discount)

    Anyways, I love the LG screen...MUCH better than the screen on my old xps gen. 2 except 1 problem....too blue! :( I can't stand the unnatural colors and "cool" color temp and was wondering what color settings ppl are using from the Nvidia color correction? I used Powerstrip on the previous laptop using "graphic arts" settings and loved it but I think powerstrip and my current nvidia vista drivers (174.61 i think) aren't playing nice and will randomly kill my screen to black when i do load powerstrip.

    Anyone have any suggestions?

    I was just about to post about this and found this thread. I've got a Samsung panel and while it appeared OK, I noticed that I had to bump up the saturation in Photoshop on some wallpapers I'd downloaded. Well, today, I just discovered how out of whack the screen is.

    My work desktop is an Dell Optiplex 745 with Intel GMA video output to a Dell 2407 LCD panel. It's not calibrated, but it looks good. I liked this picture and thought it might make a good flyer for my band, so I copied it to my key drive and opened it in Photoshop CS3 on my M1530. (8600M GT with nVidia 174.31 drivers; brightness set at 47% and contrast at 45% using online test patterns, no digital vibrance added.) I did some work on it including a lot of color correction and when I opened the copy back on the desktop (lappy isn't on the network), I flipped out at how amped up and unnatural the colors were.

    Placing the laptop next to the big monitor, I attempted to get the colors on the LT as close as I could to the source image. I used minor Levels adjustments, more substantial increases in Hue/Saturation/Brilliance (mostly saturation) and serious (35-50%) corrections with Color Balance. I have the unadjusted layer on top and masked it off to reveal the adjusted bottom. Here is the downsized result:

    As you can see, when compared to the original, the bottom half looks almost Day-Glo meaning that any adjustments on the M1530 that are meant to look natural will probably be useless on other screens and definitely in print. As a graphic artist, this is beyond unacceptable. My old Inspiron wasn't spot on, but the printed results were close enough for rock & roll; this is just a joke.

    Adobe CS3 no longer has Adobe Gamma bundled in and the nVidia driver doesn't appear to have a calibration utility either. I have a Pantone Huey Pro at home, but I've been leery of using it after the installer nuked my laptop (had to reinstall Windows to recover) and my desktop at home (luckily was able to get in to do a System Restore). More to the point, I shouldn't need a calibrator to get into the zip code of the ballpark, much less the ballpark itself. What gives? In addition to grain, Dell is saddling us with wildly inaccurate colors on a laptop that retail for over $2000 new?!?
