Thanks Chris,

I received this monitor with no bezel/case.  There are no buttons.  The monitor cable assembly has, near the monitor, 2 1/4" 5 pin sockets, & 1 2pin socket.  One circuit board on the back has about 12 unconnected jumper multi-pin connectors.

If you have any schematic, or info about where those brightness buttons connect, please let me know.

Thanks :)
