I've been looking at several of the 16:6.4 ratio ultrawide lcd panels like this one.

I'm sure they are expensive, but not the only manufacturer that makes ultrawides, just an example.
They come in 16 inch wide and larger. If you want one the side of a baywatch DMD panel, it looks like the 18 incher would do. Very interesting technology.
I would bet TBL will use something similar in this ratio. If the graphics are to scale, it looks like they will use the pyprocHDvga mode at 480x256. If I recall you worked with a similar resolution, maybe dropped it a bit to 384 by something... for Buffy?
