So no one has figured out the HDMI signal loss yet?
I have the TLX-04244b, purchased Black Friday '08 (I think), and have gone through two computers and three different graphics cards, yet with each iteration there is intermittent signal loss through the HDMI connection. The picture is just fine through VGA, but I'd rather use HDMI for convenience.
I've changed refreshed rates, synced up resolutions, changed HDMI cords... no dice.
If anyone ever figures this out, I'd be super grateful.
