MacBook Pro Retina 13' HDMI Problem
Hi all,
Two weeks ago I discovered a problem with the HDMI output on my external monitor (LG IPS 234) when connected to a MacBook Pro Retina 13'. The monitor wasn't able to display greyscale information. E.g. the underlying greyscales of a Google preview search suggestion when hovering a mouse over the suggestions. Also the whole monitor display looked washed out and fuzzy. I thought it would be a problem with the monitor, so I hauled it back to the store. We checked the monitor with a MBPR 15' and everything was fine (screens not in sync - important see below). I started thinking the new 13' MBPR might be the issue. But before leaving the store and blaming my MBPR 13' we checked out another 13' MBPR and (supprise!) the same effect again. To double check we tried another external monitor from Samsung (ok, I know if Samsung is not working with an Apple MBPR...). But seriously... The same effect again.
I contacted the Apple support and after discussing this with the 1st level (with little helpful tips ... SMB reset etc.) I was forwarded to the 2nd level. The guy wasn't able to help me either. He blamed my monitor and that it might need a firmware update. The problem could be linked with some incompatible HDCP. But a firmware update can only be done by the monitor vendor or a service partner and LG doesn't even indicate that this is possible at all.
Now my question is, does anybody else experience problems with external IPS displays and the MBPR 13'?
As I said, we tested it with 2 different MBPR 13' and 2 monitors from different vendors. In each combination the same problem. Always the same effect. For me this is an indication that there might be a bigger problem under the surface.

PS: a friend with a MPBR 15' has the same effect but only when the internal and the external IPS monitor is in sync
PS: the Apple 2nd level support promised me to give me a call regarding further steps to solve the problem (with a fixed date on Monday this week) ... They never called... Poor service Apple!
