Ok here is what I have found so far.
Nieman displays has 2 different 29in or 27v monitors
The digital one is vga 640x480, svga, 800x600 and xga 1024x768 and looks similar in spec's to the to the Makvision High Res monitor but the Makvision one only does svga and xga.
Nieman also offers a tri mode non digital monitor cga, 640x200 ega, 640x400 and vga640x480 which is similar to makvision tri mode which also does cga, ega and vga. as well as the Billabs.
Billabs is only currently offering a 27in trimode cga, ega, vga monitor at this time. Everything else that they had is currently not available any longer? go figure the current stuff is a step backwards from their previous stuff.
WG also has the 9200 and 9400
The 9200 cga, ega, vga
The 9400 is cga, and ega
Any others current 27 or 29inch monitors out there that you guys can think of.
