Unfortunately, some monitors with digital interfaces are not
compatible with some LCD displays, even though the sockets and
cables look like they match up. For example, I recently tried to
hook an Asus "Eee Box", which has an HDMI connector, up to a
Samsung LCD display using a digital cable. Couldn't get it to work
at all, no matter how I adjusted the settings on both. But when I
used an analog adapter and cable, it worked on the first try at
maximum resolution, with (fortunately) few or no noticeable
artifacts. Analog isn't ideal, but it's a good fallback.
