Hey Nickyk,
I gave up on that with the DM1000, I did not find out a way to do that.
I have to switch to a different display -X2 10 inches-
for my application it was not that bad, the controller does all the logic and the display is just that, a display to monitor all parameters, the other benefit on this display is that it can log to a stick memory so the memory limitation for logging is not a bad thing. it can do screen shots.
I hope this helps
Regards
