Aaron: I'm back from the morgue, here's the victim's remains (attached). It's apparent with only the top half of the full screen showing, (and nvidia-settings) that the card is delivering 1920x540.
Permit me to revisit this section of xorg.0.log from earlier:
(II) NVIDIA(0): --- Building ModePool for SONY TV (DFP-0) ---
(II) NVIDIA(0): Validating Mode "1920x1080":
(II) NVIDIA(0): 1920 x 540 @ 60 Hz *** what's this about?
(II) NVIDIA(0): Mode Source: EDID
Rerush, YGM dude. That was my first thought regarding the refresh rate.
I can't resist mentioning my success with ATI.
Configuration has been unchanged since the last post.
