just for future reference, many TV's when displaying through HDMI or DVI connections, will only display a few frequencies as defined by the digital video specifications. it is not a multi-frequency capable interface.
IE:
1080I (1980x1020)
720P (1280x720)
480I 480P (640x480)
running any other frequency (including those offered my soft15k) will result in a no signal or out of range type message being displayed.
