Hello All,
It's been a long while. I'm trying to get FSX to match my desktop display of 3840 x 2048, just like IL-2 and Cliffs of dover does. I have 6- 4:3 screens, 3 over 3. FSX will only do full screen on the lower 3 which is a TH2Go. If I go to windowed mode I can stretch the window to cover the desktop, but FSX will only render half the image and the top half will be black. I have read all over where people are running FSX in 4k on a 4k TV, so I know it can render a 4k picture, but are there config settings I need to change? I have set "wide aspect" = True, but I see nowhere to set the actual resolution as there is in IL-2 and ClofD config files. It seems like it should be simple. For all the threads I have read about FSX in 4k, no one says anything about the setup or config settings.

I have an I-7 3440k (or something) 16GB Ram, GTX 680 with TH2Go analog w/ 3 Dell 19" and 3 more 19" plugged into DVI, HDMI and Display port outlets. Any help is appreciated. Fluke.
