I recently purchased a 20" Pavilion 20bw monitor. Out of box, it required some correction to display accurate colour so after installing the provided drivers and HP's My Display software, I made those adjustments.
The problem is the monitor reverts to factory default settings whenever it shuts off. Intertestingly, all settings are retained (brightness, contrast, colour) accept for the gamma settings below the colour sliders; they always revert to the stock levels. I don't know if this is an issue with the software or the monitor itself. When I do use the software, it tells me to save changes to my presets before I close the program even though I have already done so and have made no further changes. The program will also not keep the 'set as deafult' option checked for my presets.
I am running the screen through a Pavilion Dv7 1428CA laptop with Windows 7.
