Have a controller running 1.0.3. Picked up an Elo ET2201 touchscreen. Plugged in and is completely functional right away, except the horizontal calibration is off on the touchscreen. In the center, it's on. But as you touch further outward, it gets more and more off. When you touch the outer LH/RH edge of the screen, it's about an inch off.

I am trying to figure out some calibration routine. Any suggestions?

Have you tried adjusting the resolution of the monitor? My ASUS VT168H runs at 1366 x 768 resolution. You can also try adjusting the sweep frequency. Available options are usually 50hz and 60hz.
