Hey, guys, I just revived an old 30" Cinema HD Display with a new power adapter. Issue is that when connected via Mini DisplayPort to a rMBP using Apple's MDP to Dual-Link DVI adapter, the display intermittently flickers on and off. I tried the same connection on another rMBP and got no output, which makes me think the adapter is faulty. I also tried resetting the first rMBP's SMC, which improved the flickering, but it still happened, just less frequently. Then, back on the first rMBP, I connected the display using a DVI to HDMI adapter, which outputs with no flicker, but at a max of 1280x800 px. Apple says that this happens when the DVI connection is single-link instead of dual, but my adapter looks to be dual-link: I suspect the adapter isn't powerful enough, so I'm leaning towards buying a new one, but I wanted to check for any feedback and experiences beforehand. It's also a simple adapter with female DVI to male HDMI, so I'm not using a separate cable. Any specific recommendations on Amazon would be awesome. Or could the issue lie somewhere else? Thanks in advance!
