This connector attribute allows you to enable or disable underscan
on a digital output to compensate for panels that automatically
overscan (e.g., many HDMI TVs). Valid values for the attribute are:
off - forces underscan off
on - forces underscan on
auto - enables underscan if an HDMI TV is connected, off otherwise
default value is auto.
Terrific! Two questions:
- inevitably, on my TV Set (SONY KDL 3000) this now doing too much
underscan. In pixels: without your patch, I used a custom modeline to
map 1280x720p to 1220x680p, so I'm 40 pixels down in each dimension. How to
fix that?
Adjust radeon_crtc->v_border and radeon_crtc->h_border in the patch to
whatever size you want.
Thanks. It turns out that I need different values to fit the screen
(probably due to native 1366/768 != 1280/720). This is of course at the
cost of slightly changing the rendered ratio, but that's fine with me.
Any plans to make those values tunables?
Also, I kind of was hoping that once I could use 1280x720 for both the
console and the X screen, it would would allow me to switch between the
two transparently. Instead, the TV takes notice of the switch and needs
some extra syncing time. Is this expected behaviour?
Thanks
Marius
