Received the X-Rite i1 Display LT today. My ViewSonic VX2250wm-LED monitor is now calibrated. I fully recommend this device. My color's look alot better than what I could get with the monitor's setting's or Windows 7's Display Calibration utilty. First you select whether you have a LCD monitor, CRT monitor or notebook pc. For LCD's and notebooks, it has little weight that you hook to the usb cable, so the device stay's flush against your screenThe device first measures the ambient light in the room. It then tells you to set the contrast to 100% and then adjusts it correctly. It then adjusts the RGB (Red, Green & Blue) color's and create's and loads a profile in the Windows/System 32 folder that automatically loads every time you use your pc. It also, set's a reminder to recalibrate on a weekly basis. This keep's your monitor looking good all the time. Can't wait until I move, so I can temporarily hook my hdtv to a hdmi port on my video card, so I can let it calibrate it. HUGE IMPROVEMENT in colorization/picture quality. If you purchase one, make sure not to use the out dated software/driver on the cd and download them from X-Rite's website.
