MacBook Pro :: Mini-DisplayPort To HDMI Disconnect Causes Sleep
Feb 24, 2012
MBP 13" (Late 2011) --> Moshi MDP to HDMI Adapter --> iogear 4x1 HDMI Matrix --> LG 24" LED DIsplay
Xbox 360 and Tivo are also on HDMI Matrix
I dock the MBP with all my cabling, close it, and use a Wireless Apple Magic Mouse and Wireless Apple Keyboard with it. If I switch to port 2 or 3 on the matrix, the MBP will sleep. I have installed both smartSleep and InsomiaX to try and prevent this from happening. The MBP needs to run 24/7, even if that might be damaging. To mitigate heat issues I run smcFanControl to change the minimum speed of the fan to a higher level. The Xbox 360 and Tivo access music on this Mac, and so if it is sleeping; it kind of defeats the intention I am going for here. The iogear has no possible way of signalling the MBP to sleep. Also a Gefen HDMI Detective is not a reasonable fix. Also FWIW: This happens even if I physically unplug the cable, not just if I switch the port on the matrix. Kudos to the first person who finds a permanent fix for this issue.
tl;dr - Prevent Macbook Pro from sleeping on Mini-DisplayPort disconnection.
I have an ATI Radeon 4870HD graphics card which has a Mini Displayport and a Dual-Link DVI port.
I'm connecting this to two Dell U2410 which each have a Displayport, HDMI ,DVI and VGA ports.
I can connect one of the monitors straight to the DVI port, but what should I do with the other? I can't find a Mini Displayport to Displayport adapter for sale in the UK. But there are Mini Displayport to HDMI adapters and Mini Displayport to DVI adapters available.
Also, would it be best to have both monitors on the same connection? If i go the HDMI route should I buy a DVI to HDMI adapter for the other port? Or have both on DVI? Will there be a visible difference between the monitors if they're not on the same type of connection?
I just got a new MBP, and I like to use my notebooks connected to my HDTV for movie watching and some occasional gaming. I was looking around at cables (mostly at monoprice) and no one seems to have a mini displayport -> hdmi cable that will carry the audio signal.
I want to run a hdmi signal over a long distance and was going to use a cat5 cable but can't find a mini displayport to cat5 converter or a hdmi to cat5 converter. I'm not sure this is even possible, but don't know why it wouldn't be because you can stream HD content over the internet using cat5. And a long cat5 cable is a lot cheaper than hdmi cables and extenders.
I have trying to get my laptop hooked up to my tv, using the apple mini displayport to DVI -> belkin DVI to HDMI cable setup (as recommended by the dude int eh apple store - which i knew and planned on doing anyway :P).
anyway, when i first plugged it in to the tv in my hotel room it worked, 1080p, then stopped .. then randomly worked again after a few ties. Once I got home i hooked it up to my sharp aquos 42 and worked fine, then after it was unplugged and tried to get it working again, it basically just.. wouldn't - i don't get a picture/signal on the tv, no options in the display cp , nor does the screen go blue when it normally finds a monitor/tv. i've tried plugging it in both ends, restarting, turning tv off/on, everything to no avail. I know the dvi-hdmi cable works, used it from a windows desktop to make sure. the mini displayport to DVI works for DVI 100% of the time into one of my monitors.
as mentioned it had worked at first on and off..., and now i cant get it working on my 1080p tv, nor the 720p one that's in my room, neither of them get a picture/signal; no options in display control panel either, or the quick display flash to blue. Furthermore, sometimes when unplugging the dvi cable from the tv i get the laptop screen flash, as when it picks the device up initially.
I never got my emailed invoice from apple when I bought the cables in in SF during macworld so I cant just return it to apple I'm sure.
any ideas would be greatly appreciated, please help this is making me go crazy... worked and now nothing no matter what i try. Oh, also tried on another, new user to see if it was a weird setting that got saved.
I know that there's already at least two threads on this, but one seems to be geared towards just one specific converter, and the other is almost 1000 posts long, so what I wanted to do here is to make a thread which is a comprehensive comparison between the available adapters.
Is it possible to switch off the mains when the Mac Mini is in sleep mode?
I've only had MBPs in the recent years and appreciate their low impact on my electricity bill very much - letting them sleep unplugged does make a difference. Now I'm contemplating a Mac Mini and while I know its power consumption is as low as with the notebooks (if not lower without display), I'm wondering if the Mini needs the current in sleep mode. I assume it does, but I'd rather know than guess.
The specification sheet for Apple's new line of MacBook Pro notebooks states that HDMI output is possible using an optional Mini DisplayPort to HDMI adapter, hinting that Apple could release a first-party solution [Update: New ports support audio output].
The bullet point is included under the "Pure digital video output" section of the technical specifications for Apple's new MacBook Pro machines. It advertises the functionality as: "HDMI output using Mini DisplayPort to HDMI Adapter (optional)."
Apple does not make a first-party Mini DisplayPort to HDMI adapter, and there is no sign of one yet on the Apple store. Existing third-party options have been available since early 2009 for under $20. Such cables allow Macs to be connected to nearly any HDTV with HDMI for video output.
Apple does sell first-party Mini DisplayPort adapters that convert the output to VGA and DVI. Both items cost $29 direct from the hardware maker.
In March, AppleInsider exclusively reported that Apple has created in its internal labs a Mini DisplayPort to HDMI connector. The alleged hardware was said to include technology that would allows Macs shipping with an updated Mini DisplayPort spec to channel both video and audio through the Mini Display port to the HDMI adapter, rather than just video.
Update: ArsTechnica confirmed that the new Mini DisplayPort supports both audio and video output on the new MacBook Pros. However, Apple also reportedly said it has no plans to release its own HDMI adapter.
The Mini DisplayPort became a part of Apple's LED Cinema Display, MacBook and MacBook Pro lines in late 2008. It replaces DVI video with a much smaller port. The new 27-inch iMac, introduced last October, only supports DisplayPort input. Unlike the Mini-DVI and Micro-DVI connectors common on previous generation Apple products, the port is capable of driving resolutions up to 2560x1600, which is commonly used on 30-inch displays.
Though the Mini DisplayPort technology was originally created by Apple, in 2009 the Cupertino, Calif., company agreed to license the interface to the Video Electronics Standard Association for its own DisplayPort standard. Prior to the agreement, Apple had to license its technology itself and made the standard free, as an incentive for rapid adoption.
Last November, the Mini DisplayPort standard created by Apple was officially adopted by VESA, which is also finalizing the DisplayPort 1.2 standard, which will double the technology's bandwidth capabilities to 21.6GB/s.
Last week, a new patent application suggested Apple is creating a new proprietary cable that could simultaneously transmit both USB 3.0 and DisplayPort data through one cable. The described technology would offer more functionality and greater data transfer rates via smller cable connector form factor.[ View this article at AppleInsider.com ]
i just bought the macbook alu. w/ the mini displayport, i tried to plug it directly to my samsung 1080p hdtv with the Mdport to vga cable but the tv didnt display anything. so i searched the web to find other solutions (Mdport to dvi -> dvi to hdmi cable), but for me that means buying 2 other cables so i was wondering if i could use this route: mini displayport to vga -> vga/dvi-i adapter -> dvi-i/hdmi cable -> 1080p hdtv? with this example, i would have to buy only the dvi-i/hdmi cable since I already have the vga/dvi-i adapter (my old MSI 6600gt one) so hows that sound? thx for giving me the answer ASAP cause I need to make a surprise presentation for my boy!
After discovering this new adapter and reading great feedback here on the forums, I picked this adapter from However, I am totally surprised that I have not seen one user feedback on how this adapter does not let your Mac go to sleep. I have tried this adapter on two macs at home, a Macbook Pro and an iMac, all latest models, running 10.6.2. Whenever I try putting it to sleep, the Mac wakes up after about 3 seconds.
I need to get a Mini DisplayPort to VGA adapter for my new MacBook Pro, but I know there are much cheaper ones about than the ones Apple sells.
Ideally, I'd like a single cable (rather than an adapter to plug a seperate VGA cable into) for a little less clutter on my desk, but if there's no decent solution I'll go with the adapter. I know most people recommend (URL), but I'm in the UK.
I have a new MBP 13", and I was wondering is it possible to use a Mini DisplayPort to DVI -adapter and a DVI-VGA adapter combined? Or is it just the safest way to buy both of the Mini DisplayPort -adapters (to DVI and VGA) separately, even though I would have an extra DVI to VGA adapter.
I am wanting to connect my MacBook Pro, which has a mni displayport, to my TV. My TV is still of the CRT variety, but supports component video (R, G, B RCA connectors). Has anyone has any luck doing this?
I have found mini DisplayPort to DVI-I adaptors and DVI-I to component video adaptors. Will connecting the two between my Mac and my TV provide me with a working solution?
I got the Aluminum MacBook late 2008 version and as most should know that the macbook comes with a Mini-Display Port. Today i went to buy a Mini DisplayPort to DVI Adapter because all my monitors at home have the DVI slot. I hooked it up and everything works fine as it should be. But next week i have a presentation to do in University and apparently my uni only have the VGA slot available, so therefore i want to know if it would work by hooking up my macbook with the Mini DisplayPort to DVI Adapter, then use a DVI-D to VGA adapter and finally a VGA cable to the Projector for the presentation?
I am trying to get my projector to display movies, tv, etc. from my MBP. I got the Mini DisplayPort to VGA Adapter but it doesn't seen to recognize any connections going out to the projector. It does not come up with the "mirror the display" option in the displays section of the system preferences. Is there a way to troubleshoot the Mini DisplayPort to see if it's working? I downloaded the firmware patch with the Mini DisplayPort to VGA Adapter hooked up to the projector but it was unable to install it since it said that the Mini DisplayPort to VGA Adapter was not detected! I'm thinking that there may be a malfunction to the Mini DisplayPort... Is there any way to check it? I tried 2 different VGA cables. The only thing left would be an issue with the adapter.
I know there have been a couple other threads on this from a couple months ago but I need to bring this back up... has there been a final verdict that the reason the mini displayport doesnt support audio is due to a hardware limitation or a software limitation?
I own a MBP 13 that I wish to connect with my Acer external mobitor. I bought a miniDisplayport to HDMI [male] cable for this purpose. Now the problem I am facing is that even though my 40" Samsung TV detects the MBP and works as an extended monitor, the MBP fails to detect the Acer monitor. However, I currently use the Acer monitor with my Mac Mini, Tata Sky+ set top box and also my Playstation 3
In a month or so I'm going to need to do a Keynote presentation with a projector. I have the new MacBook, so I need the Mini DisplayPort to VGA Adapter. It doesn't seem to be getting good reviews though (many saying it doesn't work for them). I will not be able to test it out with the project until the day of the presentation. Is there any other way to connect the MacBook to what I assume will be a basic projector?
Had been using the Mini Displayport > DVI adapter just fine with both HDTV and Dell monitor, BUT then all output has stopped completely!
No monitor is detected by the laptop (although the display does blink blue, as if it had detected it), tried different cables, different displays, using the Displayport firmware update, speaking to Apple, deleting the com.apple..plist files, etc
Edit: it also doesn't work in XP on Bootcamp!!!?
None have worked even a bit!.. Also read lots of forum posts of similar problems, but I can't find a solution that works!
I've got a Mini DisplayPort on my late 2008 MBP and I've got an MDP to HDMI adapotor that's meant to be audio ready. I can't get it working with audio (ok with display) and HDMI isn't in the sound output menu.
I had not used my external monitor in the last several weeks. I believe there have been a few OSX Lion updates since the last time I used the external monitor. I had installed all the updates prior to connecting my external monitor again. However, a few days ago I tried to connect the external monitor and all I get is a "No Signal" message on my external monitor. The Mini DisplayPort to HDMI works on my LCD TV, so I know the MDP works. I have also replaced the MDP-to-DVI cord and the external display still doesn't work.
I connected the external monitor to another computer running Snow Leopard and the external monitor works. So, the external monitor does work.
I have seen a few posts aboout this, but nobody seems to have a solution that works or is directly on point to my issue. I have tried to use all the scenarios for plugging in the external monitor and external monitor power. I tried to reboot the laptop with and withoout the external monitor connected. Same thing with the exteernal monitor plugged in and no power, etc. Nothing works. I have tried to repeatedly turn the external monitor on and off while connected to the MacBook. Again, that doesn't work. Here is what I am running:
MacBook, Aluminum 13" Late 2008 OSX 10.7.3 NVIDIA GeForce 9400M
Info: MacBook (13-inch Aluminum Late 2008), Mac OS X (10.7.3)
I bought 2 new Macbook Pro 13' , 2.9 Ghz Intel Core i7, with 8 Go 1600Mhz DDR3, Intel HD Graphics 4000 512 MB, Mac OS X Lion 10.7.4 (11E2617).
I have connected a Mini DisplayPort to VGA Adapter in order to show presentations on different LCD projectors but no image appear.
The external monitor is detected but no image is shown. I have tried to change the frequencies: parts of the screen appears but no a correct image. I have the same symptoms with the 2 Macbook Pro. Using old Macbook Pro with the same Mini DisplayPort to VGA Adapter, the slides are showns normally.
I make a test with a Mini DisplayPort to DVI Adapter and with a Mini DisplayPort to HDMI Adapter and everythings works correctly with both adapters.
I have a MacBook Pro 2012 (Lion) and am connecting to my monitor via the mini displayport and a VGA adapter. This worked fine for a while, but now is intermittent. It's not the cable or the monitor as I have tried with several and get same results. The port works fine with an Apple monitor and no adapter. I've seen several threads on this, but no solutions other than starting up with monitor plugged in which I've done.I updated the OS and it worked fine yesterday, but today not working again.
