Adjust the pixel clock in real-time, up and down to see if the image stabilizes.

You can also try this, which is within spec:

PowerStrip timing parameters:
1920x1080=1920,48,32,80,1080,4,5,36,168480,1

Same thing, flickering again.

The image stablises at 153.450, but this only gives 62hz whilst I know the display can handle 72hz on the 4850. Going a little over that makes the screen randomly flicker once between 10 seconds or so. It's quite random. It flickers all the time when I raise it higher.

The graphics card is capable of outputting 1920x1080x72Hz in little hundreds of ways, but your fixed frequency display seems to be able to handle only one or a few of these. Which one(s)? I cannot answer that - its a display, not a graphics card, issue, and your Benq firmware only recommends 60Hz.
