xrXO> EGA? EGA is _not_ digital, it's _very_ analog, and pretty old. Far as I

EGA is an analog display driven by a digital signal (TTL). It is
similar to CGA, but CGA could have only 2^4 colors possible (16) where
EGA could have 2^6 colors possible (64). On-screen palette (without
trickery) could only be 16 colors though.
So TTL is digital, but to answer the original poster, it is *not* the
same digital signal that the new digital flat panels use, by far.
If you have an older LCD display, and you are SURE it is TTL/EGA/CGA
and that it will sync to EGA horizontal scan, then it should work.
But I couldn't even begin to speculate about Xfree86 support.
