Acer Iconia One 730HD - Screen replacement

maniloff

Hello, 

 

         I'm trying to replace the screen of my Acer icona One 730hd, I bought 3 replacements with the same behaviour, there is a section of the display not reachable.

 

         All the surface of the glass responds fine but the pointer is activated in a place different where I touch.

 

         When I enable the developer mode on the tablet and see the coords of the pointer I realize that the glass has a resolution of 1024x600 but the display of the iconia one 730hd has 1280x800 and the difference between both resolutions is the not reachable area on my display.

 

         If I rotate the tablet the null section remains in the same physical position, I think this is not a software problem.

 

         There Is any way to calibrate the touchscreen? I aready try to change the resolucion and density with ADB but the problems remains.

 

Please anybody?

 

Regards!
