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
