Hi. Earlier today I found some settings on my Surface RT I hadn't seen or noticed before.(at control panel->Hardware) First off is the positioning settings, it was on by default on my device. Anyone who has any idea what this does? There's no aGPS in RT or? I Also found the touch screen calibration setting, anyone who has dared to play with this? And is there away to go back to default if you mess it up? Same goes for the clear type & display color calibration settings at control panel->hardware->display, I began calibrating but didn't se an option to revert back to default so I canceled it. Anyone who tried calibrating these settings? Tip: Also when I was poking around I found the option to remove the touch feedback indication "fingerprint" (at control panel-> Hardware-> pen & touch screen and just deselect the touch screen feedback. Here you will also find the settings for the touch screen "mouse" double & right clicks. Best regards FFX.
