Re: Design a VGA control board for an LCD.

Sorry for being confusing at the begining, but the monitor version 01
does use the analog RGB. The link for Kontron shows interesting
products.

What if I like to use the monitor on a generic VGA device (tuner..) not
sure the dot clock signal is easily found. Even on a PC VGA card, would
it feasible to carry it (100 Mhz signal) along the cable ?

Thanks,

Actually, mine is the version 01 instead of 02 of the LCD, this link is
better:

It now seems to boil down to how to generate the "dot clock" signal
from the VGA signals .

Any comments ?

Thanks,


Well the options are many ... a few bucks of some components of an
LC tank oscillator with a quartz crystal will get you your dot clock.
Any PC with an average VGA card can generate for you a dot clock
signal. Zdnet once had a basic program for download that could do that
so if you hunt for that you can play around with all the
possibilities.

It would seem though you need more then a dot clock oscillator ...
Your monitor specs indicates that it uses differential low voltage
signals for video input ... The interfaces for such are usually
expensive but Kontron produce(d) one of those starting at 72 dollars
which is cheap. Try the following url
