Hi all,
Jumping right into this in a first post because I'm desperate. I have years of experience with windows but I can't find info anywhere:

When I plug in a micro hdmi cable to my Lenovo tablet to use for watching TV (because so-called smart tv software should be declared a felony) the touchscreen calibration gets destroyed and the tab becomes useless for inputting to the Samsung TV which IMO is useless for anything except as a monitor. It seems as if the tablet slaves to the TV when I connect hdmi which in turn wrecks the touchscreen calibration so I can't navigate with the tab. Touch in the desired spot registers in a completely different place.

This formerly worked fine, now all of a sudden it's a mess. I'd be eternally grateful for any pointers.

Thanks a lot,

Rich
