I traded screens on my UD+ monitors 2 times yesterday! The connections were all the same but the mother boards were loaded with totally different electronics. The combine monitor had a lot more to it and even a removeable 8 MB memory stick! The 1st time the screen was just dark and appeared like it just wasn't gonna work so I reassembled everything back to original. I got to thinking after that, that maybe my contrast was adjusted to dark to see in bright daylight. I swapped screens again and hooked it up and looked closely at an angle and sure enough I could just make out some screen details. I adjusted the Contrast and viola it has full screen function! So now that issue is at least temporarily solved.

Now to get my RTK working again! Can't get my Cellular modem to ever get a signal anymore! Either it quit working or the connections went bad.
