Thanks Gents that is helpful, the TV sits on stand so the clip would be at a height somewhere in the center of the screen, sounds like Fugi's idea would work if mounting on top or on the lower area of the stand causes problems, the chair can always be moved closer in or out as needed, think I will give it a go, fussing around with it for month seems long I would hope it doesn't take that long.
Cheers
