You will probably have to use one of the screen designers, I use Screen4 but lots dont like it. Anyway if you open the screenset in the designer you can either make theDRO in question a bit longer if there is room or make it a bit narrower if not, it will do the same thing in allowing more digits to be seen. Another thing is if you dont require the amount of digits after the decimal that some DROs have you can ecit the string value of the DRO. For example the X axis DRO will have a string value of %+.4f but if you use metric you dont really need the 4 positions after the decimal so you edit to be %+.3f and that will put only 3 after the decimal.
