As soon as the GMA500 driver is taking over control, the refresh rate raises to 64.5Hz and the monitor reports a "signal error". For me i looks like the GMA500 driver is reprogramming the VCO to a too high dot clock. If i lower the "I9XX_VCO_MIN" value to 1300000, everything is fine. Is the "I9XX_VCO_MIN" value used in the GMA500 driver correct? Dave
