Hi I Have a Pi 3 running openplotter (http://sailoog.com/en/openplotter) and a 7" 800x480 touch screen. the desktop displays top to bottom but only about 80% from left to right. BUT the tough screen thinks the desktop is the whole screen (i.e. if it tap top left it is in the right place but if I tap off the desktop top right it puts the curser on the edge of the desktop. I have tried disabling overscan but no good. 
The screen is small to begin with I want to be able to use the whole thing!

Also FYI I tried it on Raspbian NOOBS_v2_3_0. and it did the same thing only the resolution was worse almost unreadable – Electroviolin Sep 21 '17 at 08:19

Added the following to /boot/config.txt should correct the visual screen size :
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
