Hi, First : happy new year to all and everything :D I own a matrox triplehead with 3 monitor , and i have a projector and a 4870 gs ati. I ve never had problem before with that untill last days,whatever i use windows7 or the catalyst center to extend my desktop to the projector it just doesn't work anymore. My projector work fine when it s plugged alone on my graphic card and the triplehead too. It happened to me since i updated my ati drivers. I ve revert back to my old driver but i keep having the problem. Has anyone saw the same issue around already? Regards! |

check the properties on the monitor or device connected t that port and make sure its running at 60hrtz or what ever. My tv gets "clocked down" to 30 hrtz during setup for some reason and it'll refuse to properly display. Changing it back to 60hrtz fixes it. |

That's the problem, Win7 and the catalyst does not let me choose resolution or refresh rate at all, it just doesn't extend, and it looks try to apply a 3840*1024 resolution on the projector :shock: |
