I've just acquired a nice-'n-cheap ViewSonic VA705b. It seems to be handling Amiga screenmodes (scandoubled) quite well. Previous LCDs I've tried have cut off a lot of the screen in native modes, but this one looks like a keeper. It has some trouble on DblPAL, and Multiscan, and some of the other 31KHz native modes, but good ol' NTSC and PAL work great through my CV3D scandoubler.
I'll report back if any issues come up.
