Hello everyone, first post so I decided to share my screen calibration. I am a Cinema Projectionist and Service Engineer so I have access to some very *very* expensive colour calibration equipment, and when I got my SP3 a few days ago I decided to calibrate the screen using my equipment. I am now sharing that calibration. This only works if you manually install the Intel HD Graphics driver and have access to the colour control panel. I had better results using the intel controls than other apps like Calibrize as the changes are made at driver level and persist through 2d and 3d. So, here goes: STAGE 1: Intel HD Graphics Control Panel > Display > Colour Settings (basic options) First select the RED colour Brightness +1 Contrast 50 Gamma 1 Now select the GREEN Colour Brightness -2 Contrast 49 Gamma 1.0 Now Select the BLUE Colour Brightness +3 Contrast 51 Gamma 1.0 STAGE 2: Intel HD Graphics Control Panel > Display > Colour Settings (advanced options) Colour Saturation +3 STAGE 3: Intel HD Graphics Control Panel > Power > Select "Plugged in" profile and set to maximum performance Select "On Battery" profile and make the following settings: Maximum battery life Panel Self Refresh - Enable Extended Battery Life for Gaming - Enable Display Refresh Rate Switching - Disable Display Power Saving Technology - Disabled, or Max Quality (if you want a lil extra battery life, but it makes minimal difference and ruins the display quality) If you aply the settings above you will completely eliminate the green cast of the default display calibration, have more blue "pop" and the whites should be very,very white. It will also virtually eliminate banding on greyscales Hopefully someone finds this usefiul!
