Hi all

I used to run my CRT monitor off the DVI output, because it is much more
stable than the analog output (which has slight banding). Since upgrading
to cat 3.10 and downgrading back to 3.7, the DVI out seems to be disabled,
and I cant enable it. I remember a 'use alternative DVI output' checkbox on
earlier versions of the drivers/control panel, but can find nothing now...
any ideas how to get DVI back?

Thanks in advance

right click desktop- properties, display properties-settings-advanced,
options and check Alternate DVI operational mode. This should be checked as
default when the drivers were installed

Hi Sonic, thanks for the info.
I tried that but I cant see it on any tab, including the options tab

On the options tab I see checkboxes for

Show D3D warning messages
Enable ATI taskbar icon application
Show ATI icon on taskbar
Disable quick resolution features

I remember the Alternate DVI option being here, but its now gone on my
machine (Cat3.7, 9500 pro, appears on properties as a 9700 pro because of
BIOS mod).

Looking at the displays tab, only the Monitor is enabled (YPbPs, TV, FPD are
all disabled and unelectable). I guess I need to fool the driver into
thinking I have a flatscreen display? (FPD)... but I have no idea how to do
that.

I am running a IIyama 19inch CRT btw, if that helps, and the catalyst driver
correctly recognizes it as a HM903, but if I stop the driver using DDC
information (Monitor tab then click on the monitor button to see the monitor
properties, uncheck use DDC info) I still don't get any joy.

My problem is definitely drivers. When I moved from cat 3.10 back to 3.7
(stability/speed issues) the screen went blank and I didn't know what had
happened until I moved the monitor cable... also, the card works on the DVI
output fine on win98, where I didn't go to cat 3.10 (I have a dual booter)

Those interference lines are minor in games, but they are driving me crazy
because I do a lot of document editing and they look really bad on a white
screen - headache inducing in fact :(
