Pulsar with Matrox Dual Head troubles

tycho · Post by **tycho** » Tue Jan 21, 2003 12:59 pm

I have a pulsar 2 on scope fusion on a win ME machine. I am running a matrox G450 dual head with 2 monitors attached. When I load scope fusion the slave monitor starts to blink on and off erratically. I have all the latest drivers.
Can anyone suggest a remedy or possibly another dual head card that would be more compatible with my system?
thanks

Hi,

did you disable in your matrox display-settings under options the bus mastering feature? Try it.

how do I do that? I have never heard of this setting.
thanks

-> Display properties
-> Settings
-> Primary monitor Advanced
-> Options
-> Performance
-> Disable 'Use Busmaster'

that seems to have worked. I disabled bus mastering and bitmap caching (the bitmap caching was something matrox had suggested earlier)

thanks, I appreciate your help.

woops, it still didn't work, guess it may be an IRQ problem?
