    I have the same problem with Macbook Pro 13" Retina (Late 2012) and HP ZR2240w (HDMI to HDMI).

    I'll lend my voice here. I just bought a 2012 retina MBP. I connected it to two HP w2207 22" monitors. One is connected via Mini DisplayPort to HDMI, while the other is connected HDMI to HDMI. I have used these monitors with my 13 MB for some time, so I know what they look like. WOW! Was I disappointed!!!


    The rMBP does not configure the displays properly and the images and text are blurry and fuzzy. The brightness and contrast are way off. Being Apple, there's little I can do to improve the situation.


    Just for kicks, I connected one of the monitors to a Plugable USB-to-HDMI converter. It made all the difference in the world! The HP monitor was looking like it is supposed to. But I didn't buy a new rMBP just to have to use an external converter.


    I have had several conversations with Apple Support. They suggested I buy SwitchResX and change the configuration. Thanks, but no thanks. I don't want to have to buy somebody else software to fix Apple's screw up. And, I'm sorry if I'm an idiot, but SwitchResX isn't exactly the friendliest application around.


    I have also learned that this rMBP has a hard time with external monitors when it comes to screen savers and putting displays to sleep.


    I get the feeling that the rMBP isn't quite ready for prime time. I would prefer they fix the problems, but Apple doesn't want to admit there's a problem.

    I've been a PC user since... ever. I bought a 13" retina MBP yesterday and overall it is a solid machine. I am experiencing the same issue with my display. I have a 27" LED and will test it tomorrow on my 27" ASUS display, but am not holding my breath.


    I spend 90% of my computing time connected to an external monitor. I bought the retina version for re-sale purposes.


    I have 14 days to return this new machine and am writing this in hopes Apple sees this thread/issue and that it cost them a sale.


    Good luck to everyone else-

    After too many hours and days spent trying to locate and fix this problem, I have come to the conclusion that Mountain Lion is to blame. Apple released it before they made sure they had the right drivers/profiles for external displays, and before they made sure that the OS sleep and wake functions would work properly with external displays.


    A quick example. A new 15" retina MacBook Pro running Mountain Lion, with 2 22" external displays connected via HDMI. Boot the computer and walk away. Come back after a few minutes to log in, only to find that the OS put the external monitors to sleep. OK. Except that one of the external monitors was designated as the "main" display. So the log-in window is now on a display that is asleep. The rMBP screen wakes but is blank. The external displays don't wake. Have to hit Esc or  Power keys to wake the monitor.


    I spent 12 days trying to find a way to work around or fix Apple's mistakes. I was unable to get Mountain Lion to come even close to what Snow Leopard did right out of the box on an old 13 MacBook.


    The new 15" retina MacBook Pro is beautiful, but on day 13 it went back to Apple for a refund. Why buy a brain-dead OS?

    hello guys, th eproblem is that because the RMBP (retina macbook pro) mirrors the image and renders it from 1800p to the desired resoloution, it will litteraly zoom into the screen and then the image will look right on the retina screen but will look distorted on hdmi and the other problem is that apple will also need to fix this problem with a software update.

    good luck!

    This problem with Mountain Lion occurs on external displays, whether or not "mirroring" is on.  Apple Support finally admitted that Mountain Lion needs more updates to address this problem.

    For what it's worth, I was able to see a considerable difference when I used a monitor that has a 16:10 ratio vs 16:9. I am still hopeful there will be updated drivers, but if you have this problem you can solve it with a new monitor. I have an LG L24WP but ordered a Dell U2412M and there is also a Samsung 24" at 16:10.

    To add to this discussion, have just taken delivery of a new MBP 13" non retine. External Samsung SA350 monitor looks miserable and to compund the issue it also doesn't play nicely after being wokwn from sleep... very painful experience and here's to Apple pulling their finger out pronto to provide an update.

  • The King of Limbs Level 1 Level 1


    Don't hold your breath for any quick fix of this problem. Apple has known about this for months and months. I was stunned when Apple Geniuses had the nerve to tell me that it was my eyes that had the problem because they were now "spoiled" from looking at the Retina display. Umm, excuse me?


    Or then telling me that I should purchase different external displays. What?! And what do I do with the multiple external displays I already own? As if Apple products weren't pricey enough.


    How hard can it be to get a MacBook to play nicely with external displays and be able to wake from "sleep" mode? The MacBooks of just a few years ago could do this with aplumb. Maybe Steve took this secret to his grave? Or maybe this OSX defect runs deeper than it might seem. All I know is, because of this ongoing problem and the way Apple is dealing with it, my Consumer Report survey rating for Apple is not down-graded to "Buyer Beware." I really hope they fix this long-standing problem and make efforts to repair their relationships with customers.

    I installed dual boot Win8 on my MBP retina and the original 16:9 monitor looked beautiful and sharp in Windows. Running Win8 through Parallels looked the same as the Mac OS (crappy). As suspected, it would seem the hardware is fine, just bad drivers.


    Re: the sleep issue; my mouse and keyboard are connected to the same USB hub. The mouse (Logitech MX Revolution) will wake the Mac, but I have to unplug and then plug-back-in the keyboard to get it working.


    Re: the comment about the Apple store geniuses... I took my Mac + monitor in and they also had the balls to tell me that my eyes were so used to the retina display that I must be imaging things. Lost all faith in them being able to help me any further.


    APPLE: please give Microsoft a call and ask if you can borrow the video output drivers. My eyes need it!

    I had this exact problem using a Mac Mini with an LG monitor (Mac text looks blurrier/blockier than PC text on the same monitor.).  Based on other this and other threads, I fixed it by switching from the HDMI cable to a VGA cable (using the Mini DisplayPort to VGA adapter).  (I would like to try the DVI next.)  For some reason, when using HDMI with this and other monitors, the Mac interprets the display as a Television (About This Mac...More Info...System Report...Graphics/Displays and it will say Television: Yes).  I don't know how to turn that off but this adversely affects the rendering of text.

    I have called the apple support hotline, they said it is not a known issue to them

    hope it is a sign that they'll fix it in the coming updates
