Calibrate Windows 8 Touch Screens with Greater than Four Points
Despite not being an actual mobile OS, Windows 8 has seen a surprising amount of development here at XDA. Whether it’s because of the Windows App Store or the Microsoft Surface is uncertain, but users and developers alike have been adding some great content for Windows 8 users. There is now a tutorial that will allow for more than four calibration points on touch screen devices running Windows 8.
XDA Senior Member young blade posted the tutorial for a number of screen resolutions. Users who use it will be able to break free from the usual four points to as many as 150 points. As young blade explains:
4a) As mine touchscreen is 22″ 1680×1050 I calculated the folowing line to get 150 calibration touch points:
4b) If your screen resolution is 1280×800 and you want 36 calibration see the following line:
There is support for other resolutions as well, but anything below 1280×800 requires a little additional work on the part of the user. None of it is overly difficult, and most of it takes place in the command prompt. Once done, however, the touch screen should be easier to use—especially for older applications not optimized with larger touch targets.

If you could help out an OEM and take it back to its golden days, which one would it be?
If you purchase phones from a carrier, you may be no stranger to the difficulties involved in rooting and installing a custom rom, recovery and kernel on such a carrier locked device. Add to this the extra layer of security that Samsung adds in the form of the Knox counter on its devices, and one can only imagine the roadblocks for enthusiasts who want to play around with their device without losing warranty in the process. It's a slippery slope...
