Hi John

In general terms, I think you're looking to switch off all picture processing in the screen itself, reset all the screen adjustments to zero or flat, and let the scaler do everything. Ideally you'll pixel map the display, so the screen needs to be able to accept an input without trying to rescale it, and the Edge should be set to output the pixel size and frequency of your screen. Make all of your picture adjustments on the Edge.

I still have a Crystalio scaler driving my 6th Gen Panasonic screen (SD only!) and it took ages to get set up due to the learning curve. Admittedly the picture with the scaler in situ looked better 'straight out of the box', but tweaking thereafter improved picture quality a great deal further.

I wouldn't get disheartened just as yet. Personally I reckon that a number of these products have become so detailed in their set up and tuning that a huge amount of patience is required to get them set up properly.

Cheers

George
