[mythtv-users] So close, but not quite - a 1080i modeline for my HDTV CRT

[Sasha Z]

I used read-edid and parse-edid to get the 1080i modeline for my CRT.
I turned off most mode validation methods to make sure that it was
selected as a valid mode. When X starts up, it does indeed select my
specified mode. It runs in a 1920x540 meta mode. The CRT comes up with
the mode ok, but it only takes up half the vertical resolution.

Here's a picture of what I'm talking about:

Anybody have any ideas about what I could do to fix this? I'm using a
DVI-->HDMI cable to my TV from an FX5200.
