Hello Knowledgeable All,
I have an Athlon 1.33 GHz system (ElitGroup K7S5A motherboard, 1024Mb RAM) with the
Radeon VE 64 MB dual VGA + TV-out video card. I am running RedHat 7.1.
It did not work with the Radeon VE card "out of the box", so I upgraded the kernel to
2.4.17 and installed a binary distribution of the XFree86 v 4.1.0. Everything seems to
work just fine (as far as the single-display mode is concerned), except for one thing.
For some reason, the video comes out the *secondary* DAC of the video card onto the
CRT #2.
I would *really* like to use the *primary* DAC instead.
Here's why: when the monitor is attached to the CRT #1 output (primary DAC) under the
Windows, I get really nice and crisp picture up to 1152x854 at the refresh rate of 85
Hz. However, when the same monitor is attached to the CRT #2 output (secondary DAC),
the picture gets somewhat "fuzzy" at the refresh rates above 60 Hz at *any* resolution
(in both Window and Linux). I am not exactly sure why.
I did find a block diagram for the Radeon VE series on the ATI page showing that both
the CRT#2 and TV-out get their signals off of the secondary DAC. So I'm guessing that
the secondary DAC is designed to give a signal better suited for the TV viewing, thus
the lower quality of the picture.
Anyhoo, is there a way to tell the xfree to use the primary CRT display output of the
videocard?
Thanks!
Igor.
