This is the first screen that I buy probe. The purchase and delivery went very well spent. The probe offers a fairly basic but very ample adjustment. The material itself to look very good for the little I know. The problem is the user interface. -It Offers settings without really going into explanations, so you know it or have a guide to know what setting to choose. -Once The momentum manipulation, no way to go back !! You will have to manually go in calibration files and reinstall them as default settings ... Good luck! - The setting itself is horribly yellow, normal for a calibrated monitor, but not always ideal for the current use of a PC. - The value at end calibration is not that you then have to restart the computer (this setting is much more saturated yellow than the computer once closed and the better implementation but is difficult to judge the quality of the adjustment!) - Each new boot the computer, the screen goes through different colors that take time depending on the power of the computer. It is quite disturbing and it's hard to believe that he always ends up the desired setting! - No software proposal to enable or disable the setting of the probe to start the computer according to the work you want to do it. - Adjustment of the probe required a slight desaturation gammas with Windows tools, what seems to me an aberration: whatever settings I can not desaturate warm colors. So I think it's a good hardware but the software is not suitable for an inexperienced user.
