Default workaround for 1cm dead area of digitizer?

The bottom 1cm of my touch screen no longer works.
I'm getting by using pie and rotating the phone but holy cow is it awkward! Is it possible to:

Recalibrate the touchscreen so that it thinks I'm tapping a bit lower
Or
Constantly render an empty black bar down there so nothing shows up and needs clicking in the area

Or

Replace the digitizer only (don't want to buy a new LCD)

Or..

Anything?

Thanks!
