Hi if you think about using compsite it is all ready 15khz input i dont see any problems there. as for quality dont expect the clearest image in the world but keep in mind that even the new nintendo arrive with composite cable as stock so it will be good enugh for games but workbench may be a little disorted .. also furthermore you should make sure it is not a widescreen flat panel as these drag the image .. i use and have used several lcd screens "lcd tvs also if you wish" out of these i used a 7" for my car and it worked great. Otther people may complain the Lcd does not work in 31khz displays "require scandoubler or dubblepa\ntsc but for composite or rf in it almost always work but the 31khz depends from lcd too lcd
EDIT some panels are reported to have built in 31khz to 15khz converters on the vga port as well with a autoseek funktion but this is far from usual and will most liketly not be found on a cheap alternatives.. I did see this on the Lcd tv of a friend but the picture was ofcource out of scale But it worked only by ading a vga adapter to the miggy "this case a 1200" .. hope it helps :-D
