Wim,
I have had it working with a native graphics card. It is not a "Native" resolution but I set it up in the custom resolutions options and the monitor can take it. Here are the specs:
2048x1536
Refresh Rate H:95 V:60
Front porch H:48 V:2
Sync Width H:32 V:4
Back porch H:80 V:38
Polarity H

ositive V:Negative
Pixel clock 209.250
Aspect Ratio 4:3
Is there any way I can add that resolution?
