How to stop autodetecting display?

[Guest]

Is there a way to stop vista from autodetecting the displays? I have a PC
running Vista Home Premium as a media PC, nvidia 5200FX vid card with VGA,
S-Vid, and DVI outs, using the DVI to my receiver then to TV for the display.
Frequently when the receiver is off, the computer will switch the display to
the S-Vid (and probably the VGA) and turn off the DVI even though the S-Vid
isn't connected. I have to go in and connect the S-Vid then tell vista to
enable the DVI. Anyone know of a way to manually manage the displays?

It is your 5200 graphics card and its driver that is performing the problem
caused by the receiver being turned off.
Regretfully Nvidia has not released an updated Vista drivers for the 5200
cards since the Vista release.
Hopefully someone with a 6,7,or 8xxx card will respond to this thread if
there Vista drivers work solve this problem.

The card and Vista driver are working fine; when I connect directly to the
TV, the problem doesn't occur, probably because it always senses that
something is connected even when the tv is off unlike on the receiver. I
think that my problem is in the auto detection, just that one feature, if
someone knows of a registy setting or something...

As I stated above the auto detect is done by your graphics card which your
TV or receiver is connected to from your graphics card and not by your MOBO.
Although your TV is "off" it is really only in standby and therefore has
power available to it for its DVI connection logic.
