Vertical Refresh Rate Too Low
Hello,
I have a WinXP (SP2) system and an Intel 865 motherboard. I'm running a Matrox G450 (AGP) and a Matrox G450 (PCI) and am using 3 monitors, each set to 32-bit color and 1024x768 resolution. According to the specifications on these boards I should be able to set the vertical refresh rate to 160Hz (although all I want is 100Hz). I'm using an Envision 910 monitor, a Sony E400 monitor, and a KDS XF-9bi monitor. The Sony is capable of at least 100Hz (maybe more). I have installed the correct drivers for each monitor. However, when I look at the properties for the monitors none of them show a choice greater than 85Hz. I've unchecked the "Hide modes that this monitor cannot display" box but 85Hz is still the top choice. Any ideas/suggestions? Thanks, Ray Mitchell |

Rick,
Thanks for the suggestion. I downloaded and tried the tweak, but it instructs me to then use the Matrox Monitor Manager to update my monitor profiles. However, the monitor manager does not support either version of the G450. Go figure! Ray "Rick" wrote in message ... "Ray Mitchell" wrote in message k.net...

Have you tried adjusting the refresh rate directly through
Powerdesk? Look under the Matrox-specific options. "Ray Mitchell" wrote in message k.net... Rick, Thanks for the suggestion.

Rick,
I was able to go in and click the refresh rate 1Hz at a time until it reached 100Hz, then save it as a custom configuration. Thanks for your suggestion. What I still don't understand is why this should be necessary. In the past I've always been able to chose the desired refresh rate in the monitor settings, but as I mentioned, in this case it only lists rates up to 85Hz. Ray "Rick" wrote in message ...

Maybe they think anything over 85Hz isn't necessary or discernable? Who knows. Rick |

I was able to go in and click the refresh rate 1Hz at a time until it reached 100Hz, then save it as a custom configuration. That's always been the best way to do it with the G4xx PowerDesk drivers. Make sure you save your customisations out as a file so you can instantly re-import the settings it if you ever have to reinstall your system, or wipe/reinstall a future Matrox driver build. What I still don't understand is why this should be necessary. In the past I've always been able to chose the desired refresh rate in the monitor settings, but as I mentioned, in this case it only lists rates up to 85Hz. The reason for this is that one (or more) of your monitors is using VESA DDC signalling to broadcast its list of acceptable refresh rates, or alternatively one of the .inf files used for your monitor(s) contains an incomplete or incorrect set of refresh rate definitions. In either scenario, XP will offer you a limited set of refresh rate options in the standard Display Properties/Monitor selection sheet, and 85Hz is normally the highest you'd expect to see there. As you've already found out, the PowerDesk advanced monitor customisation routine is waaaay more powerful than what you're given as standard with WinXP. You can do far more than define additional refresh rates with it, so have a play and see what you can do. -- Richard Hopkins Cardiff, Wales, United Kingdom (replace .nospam with .com in reply address) The UK's leading technology reseller www.dabs.com Get the most out of your digital photos www.dabsxpose.com |
