Spliting the sync wires seem to have done the trick!
Have now removed the DALR6 CRT & DALR6 CRT2 keys via regedit as i dont need c-sync via winmodelines anymore??, also have removed the positives sync values for the monitor_specs is all this correct?
But have noticed that now there is approx an inch boarder at the top of the screen and i have the V position pot to the max so cant move the screen up anymore. Is there a value in monitor_spec line that can shift the screen upwards?
What Monitor_spec line should i be using?, either...
15625-16200, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.160, 1.056, 0, 0, 288, 448
or
15250-15700, 49.5-65, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 288, 448
for a 15khz CGA monitor?
