It's funny to see how many Hacker News writers use Mac, the most closed hardware+OS, most anti-hackish. How about renaming HN to stand for Hipster News?
How is that closed?
Just a guess: The patterns in the examples seem to be horizontal, meaning the raw (pre 'cable encoding', usually 8b/10b) bit pattern of the display output would be repetitive . It wouldn't be out of the question that a slightly improperly electrically balanced or terminated output could cause signal integrity issues, including ringing (voltage exceeds spec on rising / falling edges) which could trigger safeguard circ…
I don't have any electrical knowledge. care to elaborate? Is that a problem with the cable, terminals on the devices, the mini-displayport dongle or either? The problem also only seems to occur on Retina Macbook Pro's
Most people have been around a cell phone which was near an audio speaker and heard it make those awful snap and pop sounds.
It doesn't make sense initially that you would hear anything like that from a phone, after all they operate at very high frequency, 900 - 2400 Mhz, definitely not audible frequencies. But, the system works by breaking up radio time into chunks, several hundred chunks a second. The relative spacing of the chunks, a few hundred a second, creates noise that is easily picked up by the speaker and turned into audible sound.
In the same way with the laptop you've got this high frequency signal: HDMI / DVI but when there are particular patterns of bits being carried you can get lower frequency content, similar to the chunks being used by the cell phone. Just like the coil in the speaker gets excited by the radio chunks, you could have a problem where the output circuitry of the RMBp gets excited by these rare low frequency patterns leading to problems with the display.

Posts like these are why HN can't have nice things anymore.

If my guess is correct, it would be a problem in the design of the output transceiver circuit on the RMP's motherboard, assuming the cable and receiver in the display are built to spec. Could be an IC issue, could be the impedance control of the connector, could be the impedance control of the traces on the circuit board, could be poorly chosen passives, could be interference from nearby circuits, etc. I wish I could…

A Mac is the only computer on which you can legally develop for all major operating systems, including mobile. How is that closed?

This is a good start:

That is literally the dumbest argument I've ever read on HN.
display shuts off immediately.
Was quite confused when opening stopwatching.us yesterday, thanks for pointing it our here :)
