    Display drops out every 5-10 minutes

    Hooked this up to my Pioneer plasma TV and it works, but the display cuts out every few minutes (re-syncs). I've used other laptops with this display and had no problems!

    unibody/aluminum macbook 2.4GHz

    • Written by

    AFTER purchasing the MB572Z/A miniport/VGA dongle with my new FB467LL/A macbook - the one with the "advanced" nVidia GeForce 9400M set, I read in the user's guide (p.66) that "Note: Your MacBook supports external display resolutions up to 1920 x 1200 on Apple DVI displays and up to 1600 x 1200 on VGA displays." Bullocks!
    The nVidia set supports "Maximum VGA Resolution 2048x1536".
    I can't fault this piece of hardware for Apple's lousy implementation of this "brand-new, industry-standard port". Or can I? Will I have to pay $50 for a "better" version of this later? I'll be counting the days I have left to RMA my macbook -

    monitor re-syncing

    • Written by from Saskatoon

    I have tried this on 4 different monitors 3/4 would re-sync after around 5-10mins of use and then repeat. this gets extremely annoying when doing some work and your screen goes blank then turns back on in around 2 seconds.

    Very poor

    • Written by from Camberley

    I've got one of these to connect my Macbook Pro to my Samsung TV but as with everyone else, the TV doesn't recognise the output from the laptop. (It works find with my Dell laptop and Windows XP).

    The result is that the adapter is useless.

    Beware - Certain Monitors Have Problems With This Adapter

    • Written by from HAYWARDS HEATH

    I bought a new Alu MacBook back in November 2008. After a few weeks I decided to buy one of these adapters.
    Every 5 mins or so my screen goes black for 2-3 seconds before coming back on. This has been mentioned by other reviewers here but just wanted to add this is a common problem.
    I have called AppleCare and been into Apple Stores too many times. Apple do not appear to even acknowledge there is a problem! Look on Apple's own Forums and you will see the numbers having issues. I would stay clear until Apple fix the issue.

    Doesn't work with data projectors

    • Written by from London

    This adaptor is very disappointing. I found that it works fine with some small (20 inch) Samsung monitors that have a VGA input but it doesn't work with any of the data projectors I have in my university department so I can't use my new MacBook Pro (unipart aluminium case) for Powerpoint presentations, which was one of the main reasons for buying the laptop. The problem seems to be that the laptop senses the data projector ( and scales down the laptop display to VGA) but the projector doesn't detect the laptop (and so fails to display the image from the laptop screen). My old MacBookPro (Intel core duo) works fine with all data projectors (using the DVI to VGA adaptor) and I'm now in the silly position of having to use the old laptop for all travel (conferences etc) plus teaching in the university. The wonderful looking new MacBook Pro has to stay at home. Apple needs to issue a firmware fix or a better adaptor as soon as possible.

    Does not work with Samsung LN46A550

    • Written by from Huntington Station

    I own a 46" Samsung LN46A550 LCD TV and this cable does not work with it. The System Preferences on the mac detects the monitor but the cable won't output my Macbook Pro screen. What a waste of money

    No go with Samsung LCD

    • Written by from Ottawa

    Thought I would put in my two cents. I purchased this adapter in order to use it with my 46" LCD Samsung only to have the same problem as most people here.

    Macbook detects the TV but the TV can't detect the macbook. I tried many things with no success. I called Apple and they told me that I would have to call Samsung to see what they could do since it was a problem at their end (I don't believe that for a second).

    I'm hoping for a firmware/driver update that can fix this. Otherwise, when Monoprice comes out with their mini display port to HDMI adapter, I'll just buy that instead.

    Another problem with Samsung TV

    • Written by from Thorold

    I have a Samsung 530 series LCD tv and this adapter doesn't work with my macbook. The display system preferences panel detects that it's a Samsung tv, but the TV doesn't detect a signal. I tried an older macbook with the mini-DVI to vga adapter and it works perfectly, so it seems like apple messed up on this one. I have yet to see whether any display works. I hope it's just a software thing.

    VGA adapter works poorly with Sony GDM-F520 monitor

    • Written by from PARIS

    When my old Mac Book Pro (late 2007) +DVI-to-VGA adapter was plugged to my Sony GDM-F520 professional monitor (which does not feature any digital input) with a 1.8m meter long cable, I could get resolutions of 1440x1920 at 85Hz without any problems. My new Mac Book Pro (2.53GHz)+Mini-Display Port-to-VGA adapter + the same 1.8m long cable offers only 1200x1600 at 60Hz or 1400x1050 at 85Hz. In addition the monitor is re-synching at random time (black screen), hopefully not too often. The is also a mechanical flaw: depending on the cable fabrication, the cable screws may not reach the threads on the adapter side.
    It is an understatement to say that it is disappointing. Now I fear that I will have problems when using my laptop for conferences where projectors use almost exclusively VGA connectors and sometimes long cables + switches. I hope that apple is taking care of that problem and will find a solution quickly.

    Mini DisplayPort to VGA Adapter won't work with Samsung LCD TV

    • Written by from San Jose

    My aluminum Macbook with the Mini DisplayPort to VGA Adapter won't work with a 46 inch Samsung LCD TV. Apparently lot's of users are having this problem. The Samsung TV won't even switch to the VGA PC mode with the Mini DisplayPort connected, in order to get the Samsung TV in the PC mode you have to unplug the DisplayPort, put the TV in VGA PC mode, and then you can plug in the Mini DisplayPort, but it still won't display any video from the MacBook. My Samsung TV worked fine in this mode with a Windows XP laptop, and displayed 1080p fine. It appears to be a problem with the DisplayPort Adapter, and it's inability to either drive the VGA signals or send the proper serial data stream informing the Samsung TV of it's resolution.
    To get around the problem I had to buy the Mini DisplayPort to DVI adapter along with an HDMI to DVI cable. With this solution my Samsung TV worked fine with the cable plugged into the HDMI port, and it displays perfectly in 1080p mode. I think this is the only solution for the vast number of MacBook users out there trying to drive LCD TV's.

    I've bought this part twice trying to get my Unibody Aluminum Macbook to work with my Samsung LN40A550 40" LCD. Does not work. The Macbook finds the monitor, and even shows supported resolutions and refresh rates, but the TV acts like no signal is getting to it.

    Come on, Apple. It's only the most popular television / monitor brand out there. Let's get a fix on the way, please. Or, at least acknowledge the issue.
