So I need to diagnose what's gone wrong вЂ“ is it just the cards, or is it the motherboard? While I could test the apparently dead graphics cards in my new Mac Pro, I'm reluctant to do that for fear of killing it too! It seems bizarre that so much damage cound have been done by simply replugging a monitor! It's tempting to buy a cheap PC just to see if I can diagnose it better on there, since more diagnostic tools on DOS/Windows, firmware twiddling might be possible, and it will have built-in graphics that should always work. But I'm now left with this half-dead Mac Pro that I'd like to sell, along with 3 not-terrible graphics cards, but it's obviously not going anywhere without working graphics, and I can't tell what's really happened to them.

I then tried using the original 8800GT that was in the Mac Pro when new, and I still have lying around. An SMC reset should not be necessary except as a last resort in cases where a hardware issue with the power management system is suspected. I figured I must have killed the graphics card, so I bought a new one (the same model). I rebooted, no chime, the graphics card fan came on full speed, and there was no video output.

One of the screens came on, the other didn't. Press the Power button on your Macbook Pro to. I unplugged the old monitors, plugged in the new ones (using Samsung's supplied HDMI cables, the only ones I've found that will actually run them at their full 144Hz speed).
