dvi to video registers but no output.
using dvi to vga adaptor, when plugging in it changes the screen to blue briefly then you get all the options in display prefs, and the 2nd monitor/tv displays as expected.
But then when you want to use dvi to video the laptop screen changes to blue briefly again as expected, but the 2nd screen is receiving no signal, and nothing happens when when clicking on "detect displays". my local mac dealer says it is the video card (part of the mother-board @ £500) and they didnt even test anything, and the warranty ran out 1 month ago.
i only found out this problem a week ago as it was the first time i needed to use these outputs.
could anyone give me any advice or ideas on things to try.
Got all the updates?
Use VGA the graphics the card is soldered to the MB/LB not a DIY replaceable part... you might be able to find someone with a reball machine that could fit a replacement but it might be smarter/more economical to just replace the MB/LB.
Extended Warranties some folks swear by them, others swear at them...
