    I thought LG made smaller TVs with serial - just going off of memory.

    See if you can find something in Sharp. I programmed once a couple of 20" sharp monitors via RS-232.

    Just keep in mind that you might need to contact Sharp Technical Support to enable the RS-232 option. I am not
    sure but i think the Integrator who hired us had to switch on the TV set in a special mode in order to boot it in a
    hidden setup menu. And in that menu he changed some Hex values.

    Most LG models have RS232 - the protocol is good too, as it will allow you to send 'IR' type commands such as nav up/down etc - ideal if the customer wishes to use internet TV etc.

    The other option is a Panasonic Viera and use the 3.5mm service port - it's not advertised as a RS232 port, but it is.

    If you go with LG make sure you get a commercial monitor and not a consumer one. In my experience (admittedly a couple of years ago) the 232 ports on the consumer ones have a bad habit of shutting off if you talk to them too much, and the only way to get them back is to pull power from the monitor.

    Sharp has the LC-26SV490U. I have no personal experience with that specific monitor, but I've never had an issue with the larger Sharp consumer displays that have 232 ports.

    The RS-232 in the sharp aquos stuff is accessible from the Hotel mode menu, if you need a copy of the doc, get in touch. Infact tweaking some of the hotel mode entries greatly increases the reliability of working with an AMX controller, especially if you are stuck using IR and not RS232.

    The LG consumer TVs have come a long way in the last few years. The protocol seems much more standardized and I have had no trouble with any sets I've worked with recenly.

    Have you effectively controlled that Maxent via the RS-232 port?

    Yes I have, I have the protocol laying around somewhere. I'll send as an attachment when I locate it.
