GRT posted version 31 of the EFIS software for the Horizon I High Resolution Display.

I downloaded the file (5.1MB) and installed it on the dual screens in my RV-10. The upgrade took about five minutes per screen. I have not flown with it yet.

The most obvious change is the "elevator style" tapes for the altimeter and airspeed.
 
Dang!

All I could do was download it to my thumb drive - I won't get back to the airplane to try it out until late next week!
