I have a Samsung LW22A13W which will happily accept a 720p signal from my HTPC but only at 60Hz. I cannot get any signal when connecting my HD850 via HDMI-DVI lead as it say unsupported mode. I can only think that the HD850 outputs 720P at 50Hz hence it works fine on my Samsung LCD Rear projec but not the little one. Many ideas before the HD850 goes on ebay ? cheers Neil.
