FD Display is a TSR, not a device driver, and needs a lot of UMB free to "loadhigh" even if it doesn't use it all, so first make sure you have enough (I doubt it, though, 64k or such IIRC). Also try without "LH" and/or with FDAPM loaded after and/or make sure DISPLAY.EXE isn't UPX'd / compressed.

EDIT: Honestly, if it were me, I would remove everything loaded before it and try loading those after it and see if that helps. (You have so much loaded that obviously I'd be hugely surprised if something didn't crash!)

EDIT #2: I forget exactly, but I think FD Display will try using XMS if it can, which implies JEMMEX. Try removing "X=TEST" (which isn't 100% guaranteed, I think) and "PGE" since you don't need that. When things go wrong, you have to play it safe until you know why.
