I'm really curious about this: How did you come up with this modeline?
Every calculator i've tried says somewhere between 700 and 1000Mhz for the pixel clock, is there something wrong with using these to calculate digital resolutions?
It actually works, which i'm happy about, but I'm playing around with them and the closest i've come is from eizo's site:
The frequency with which dots (or pixels) are illuminated on the screen; how quickly a single dot can be produced on the screen. A general formula for calculating the dot frequency is: D x 1.25 x fH (the number of dots in a line multiplied by a constant between 1.25 and 1.3 multiplied by the horizontal scanning frequency).
