Apple 13" RGB monitor as VGA display

[9166188]

Hi,

I have a 13" AppleColor High-Resolution RGB Monitor (M0401).

I really like the monitor and wonder if it can be used as a VGA monitor for Windows machines also. Since its doing the same resolution as VGA's 640x480, I guess this should be possible. So I tried connecting it to a Windows 7 thru a VGA to BD15 adaptor, but nothing comes out. Is this because of something to do with adaptor wiring? I have seen a special adaptor with dip switches for Macs to connect a VGA monitor.

Anyone know this stuff can help?

Best

Ken

Apple's display had a fixed resolution and refresh rate, with a horizontal frequency of 35 kHz, and a vertical rate of 66.7 Hz.  The original VGA standard was 31.4 kHz / 60 Hz, so not compatible with Apple's display timing.  That's also what basically every PC with a "VGA compatible" or "SVGA" video card defaults to, since it's the "lowest common standard". If you were to configure your VGA card to output with a horizontal frequency of 35 kHz, vertical rate 66.7 Hz, it should work, but you'd have to do that before connecting the Apple display.

Thanks for the info!

On my Win7 setting, it does not have the option to the specific h35 kHz v66.7 kHz. Instead it has the options of 60 or 70 kHz vertical on 8 bit color 640x480. But this does not show anything on screen.

Looks like its better to try the Apple specific 35 / 66.7 kHz on Linux someday as I don't have one with me here.

it would be easier since its close enough, to re-adjust the oscillator to handle it.
