Screen Colour Calibration Gets A Universal Version, Takes Aim At More Phones

Posted by in Froyo 2.2, News, Samsung

After several rapidly-iterated versions, storm99999’s Calibration Settings hack is branching out from the Nexus One. Now at version 4.1, the hack has morphed into a standalone application with a GUI allowing you to set individual levels for each of the Red, Blue and Green subpixel channels.

It also no longer requires CyanogenMod 6 – I have it running fine on my rooted, stock FRF91 Nexus One. A user has reported that it is working well on their Samsung Galaxy S running the leaked JP3 firmware. This is especially good news because of wide-spread complaints about blue tinting on the SGS’s Super AMOLED panel.  It’s quite possible that this will work on any Android device if you have SuperUser permissions.

SurfaceFlinger Hack Brings Screen Calibration To Nexus Ones Running CyanogenMod 6

Posted by in Development

 

Remember Jeff Sharkey’s screen tool that allowed you to turn off the sub-pixels of specific colours on the Nexus One’s PenTile display, in order to save battery?

XDA-Developers member storm99999 has just published a hack allowing you to apply a different colour calibration profile to your N1’s screen using the very same function. However, rather than switching sub-pixels off completely, this hack changes the voltages and thus the colour balance to suit a particular colour temperature. In its current implementation, the mod changes the screen temperature from 9000K to 6500K, a slightly warmer hue.

Originally available as a flashable ZIP for ROMs supporting the original SurfaceFlinger hack, storm99999’s colour calibration profile is now included in the latest CyanogenMod 6 Nightly.
