Documentation for custom resolution settings for GMA HD (core i5)

[idata]

I purchased a system with an i5 processsor and win7 that I am trying to get to work with a monitor with a low resolution. I cannot suppot higher than 800x600. I have documentation for the monitor that gives me scan per., sync pulse, front porch, active vid., and back porch values in us (for horizontal) and ms (for vertical) units. But I cannot tell what units the driver wants under the advanced page on the Custom resolutions tab of the driver.

Does anyone know what units I should use or have a manual for the driver?

Thanks,

-Patrick

Did the monitor manufacturer provided a driver CD?

After you install the drivers it should recognize all the supported resolutions.

It's an arcade monitor (Wells- Gardner D9800). so no .INF file of EDID data that I am aware of. I just have resoluton setting information for various resolutions that look something like:

Scan freq. 15.725kH 60.018Hz

scan per. 63.594us 16.662mssync pulse 4.688us 0.191msfront porch 2.187us 0.190msactive vid. 50.00us 15.263msback porch 6.719us 1.018mssync polarity ( - ) ( - )

The advanced screen I mentioned has blank fields for settings with the same names, but I have no info on the units it wants (no decimal point accepted) and my trial and error has not worked so well.

were you ever able to resolve this? I have the exact same problem. Monitor works with Standard VGA driver, but not with the Intel HD Graphics drivers installed, no matter what I try.
