flickering with samsung2233rz + projector connected to gtx460
Hello :)

strange problem here. i have upgraded from a 8800gt to a gtx460.
attached to my pc is a samsung 2233rz and a hitachi projector (old one with 800x480).
never been a problem so far, but since the upgrade...

whenever i try to connect my projector via dvi-to-vga adapter the samsung 2233rz flickers every 2seconds,
as if the graphicscard tries to recognize the projector and his resolution. endless loop. disconnection of the projector stops flickering. projector works fine with my thinkpad t41.

i tried to use a different adaptor, different cables. newest driver is installed, everything works fine without projector. i also tried to change the samsungs refresh rate to 60hz before attaching the projector.
with my 8800gt everything works fine. 2dvi-ports and one hdmi-port, doesnt matter which dvi-port i use with the adaptors... same problem. also an old fujitsu 17" lcd works perfect via vga.

all suggestions are welcome, thank you
