RE: [Linux-fbdev-users] radeonfb: strange blue lines after 'setterm-inversescreen on'

[Hihn, J. <Jas...@ve...>]

There is a i2c interface between the card and the monitor that tells it
what the monitor's capabilities are. If your monitor can't do it, it
won't let you, because you can damage hardware that way.

15bit I think dates back to some [matrox?] cards, circa 1995. No one
else really had/supported that.=20

Just tried, same here (Radeon 9200 Ya). If I ask for 15-bit I get 16, if
I ask for 24 I get 8. 8 is OK WRT blue background, 16 and 32 are not.

BTW, how do you get 75Hz vertical refresh? I just can't. Whatever I ask
through lilo, I end up with 60Hz (both fbset and the screen's OSD
agree).

Thanks.
