bbrz Posted July 27, 2018 Posted July 27, 2018 (edited) AMPCD brightness controls the right DDI contrast in HSI mode. Right DDI brightness and contrast controls are inop in HSI mode. I usually turn off the AMPCD and it took me quite some to find out why I didn't get the TACAN symbol etc. displayed. edit: The AMPCD brightness control doesn't work for the AMPCD. It's just on/off. When displaying the TACAN on the AMPCD the brightness control changes the contrast of the AMPCD and the contrast control controls nothing. Edited July 27, 2018 by bbrz i7-7700K 4.2GHz, 16GB, GTX 1070
