I have seen some similar threads but I since do not have/use FSX or Vista, I thought I would post a new topic.I have the following setup on my PC which I built myself: XP Pro SP3 ASUS Motherboard Intel E8400 3GHz (Duo Core) 2 Gig RAM 2 NVidia GeFroce 9800 GTX+ 4 Monitors 1100 Watt Power Supply Realtek High Definition Audio on the Motherboard CH Flight Sim Yoke Surround sound speakers (Using only the subwoofer, main, and two front speakers) UT Terrain UT Traffic Dynamic Weather from FS9 Ground Environment Pro Radar Contact v 4.3 I have the PMDG 737NG-600/700 version. I have been running the PMDG 737NG-700 version (2D cockpit only) on FS9 for a couple of months now with the sliders all the way to the right with only an occasional visual hiccup on the ground with some flashing images. I was using the NVidia drivers version 185.85. I have the monitors configured to show the main panel view looking forward on the center monitor. I have a monitor on each side of this one showing the forward left and forward right views. The fourth monitor sits on top of the main monitor and shows the overhead panel. All the views are in windowed mode. On the left monitor I also show the radio stack. On the right monitor I also show the throttle quadrant and the CDU. I also have two little add-ons on the right monitor which are the announcements panel and the doors panel which were freeware downloads. I would usually get black screens on the glass displays when I started up. I would cycle through the views and when returning to the main cockpit view, the panels would show fine. This was is nuisance but nothing more as once the panels had
