Thaks for your input guys but it's a moot point now, my SCART cable arrived and it did seem to fix the positioning (for TV modes) but for some reason all colours with a red value greater than 128 come out a horrible shade of orange / yellow through the scart connection.
Colours were fine through vga & rf so I know the monitor can handle the colour range, I then tried the cable with another scart telly I have and the colours were fine on it so I know the cable and my miggy aren't the source of the problem.
Tried various adjustments on the LCD but nothing changed the wierd colours so the screen's going back to the shop. (unless anyone has any simple ideas I've missed for sorting it ?)
Shame really as the screen was a bit of a bargain at £150.
Daniele:
It does handle 15khz through RF, scart, svhs and composite but not through the vga input.
Anyone got any suggestions for an alternative in the same kind of price bracket, 15" - 17"?
(I'd go for motorollin's one but I haven't got an asda within 70 miles of me and I can't find that model online anywhere :-( )
