It's also possible that the original "Display" command will work properly if you increase the "Number of Repeats". The "Number of Repeats" (now nameless) parameter is under Device > Troubleshoot > DVD responds to some commands either too many times or only occasionally. If you want to test the original "Display" command, you will have to re-learn it in regular mode (or delete the device to erase all learned command) unless you chose a different name when you learned it. You should also try all the commands in Device Mode. Maybe there are more than one "Display" command under different names.
