Two weeks ago, I decided to take the plunge and purchase a NIB Gefen DVI-to-VGA adapter on eBay. It arrived today, and of course, I've got problems.
Firstly, my ADC monitor remained blank, even after the IIfx completed its RAM test (and this was with the 8.24GC Card). Adjusting the Gefen's EDID switch from Internal to External and vice-versa yielded nothing. More seriously, I noticed a strong electrical smell from the Gefen, so I promptly shut everything down. Fortunately there was no smoke, but even three hours after conducting this maiden test, the Gefen still has a pungent electrical scent.
But we're not done yet.
Now the ADC monitor refuses to display anything - all I get is the bright solid Power Indicator lamp that now immediately powers on and stays on when the monitor is connected to an outlet. Swapping ADC-to-DVI adapters made no difference (I have two). Zapping the PRAM on my B&W leaves me with the same result. Did the Gefen fry something in the ADC monitor? My IIfx was not hurt at all during this experiment.
