Thank you for the reply
I think my resolution is correct.(but please tell me if I'm being an idiot) I have a bit of a weird setup, since I use this pc for more than DCS. But it looks like this, I followed the forum post on here, to export the MFCDs.
I changed the options.lua like you said. It started(good), I could change the resolution to 1920x1080 for a single monitor display, but when I tried the monitor setup I used to have it went into black screen again, I included that lua file as well(it worked before the update, so no changes since 4 or 5 months actually to the lua file).
If
1 Screen + 2MFCD .lua
