Thanks Alan
What Ive found is that a 2 year old Viewsonic vx924 with a DVI doesnt work from HDMI to DVI, all you get is a blank screen, but there is something being transmitted, from the extender to the monitor as the light goes green on the monitor.
With a new Samsung 2232bw all works fine and dandy, although ironically, as this is the main monitor from my media centre, the picture is rather shocking and very pixellated, Id love to get the viewsonic working, as I dont see why it doesnt but am faced with buying another monitor just for the extender
My best idea was to get a vga to scart/composite cable and try that with the viewsonic, although the man in maplins said it wouldnt work, which wasnt great either being corrected by him, or finding a cul de sac
If you have any ideas love to hear them
Thanks
