Actually, 8.3.1 is an old program. Igo8 is now up to 8.3.5. That old program was developed for the PC. The newer program will not work on a PC just yet. I don't think that those applications you refer to were available back then but I could be wrong there. Also the resolution you refer too is not available so you can't change anything yet. FYI, you would make a res change in the sys.txt.
