Mac Pro :: No Signal From Mini DisplayPort

May 29, 2012

I just recieved my Mini DP to DVI adapter so that I can use my second 23" Apple display. I just upgraded to ATI Radeon HD 5770 so now I have 1 DVI and 2 mini DP. I want to run 1 display off of the DVI and 1 off of the Mini DP. Both displays work with the DVI port but neither of them work on the Mini DP with the adapter.

I know that I need to upgrade to Snow Leopard for the ATI Radeon HD 5770 to fully function. I am waiting for the upgrade to arrive in the mail. Do I need to be running Snow Leopard for the Mini DisplayPorts to work at all or is there something I can fix before the upgrade?

Mac Pro :: Using Mini Displayport To DVI, HDMI Or Displayport?

Oct 28, 2009

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?

Mac Pro :: Mini Versus Displayport... Possible With A New Graphics Card?

Jan 5, 2009

Since video/graphics out is achieved through graphics cards with dvi ports...

surely a card with mini displayports would make exisiting mac pro's compatible with apple's new LCD displays?

Am i wrong?

Would this be difficult to do for a graphics manufacturer to do (forgetting that this obviously would be a card aimed mainly at Apple users and probably not worth the effort....)?

MacBook Pro :: Get Mini DisplayPort To VGA?

Apr 17, 2010

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.

Intel Mac :: Why Mini Displayport Not Functioning

Jun 18, 2012

I recently purchased a Mini Displayport to HDMI adapter and 30' HDMI cable to connect my iMac to my 42" Panasonic TV. It worked at first, and then suddenly didn't. I believe I upgraded from OS 10.6.7 to 10.6.8 in between it working and not, could that be the problem? I know the problem is not the cable as I tested it with my XBOX. I don't have a way of telling whether or not it is the adapter itself though though. When it plug it in, there is no blue screen on the iMac like there was at first. When I click 'Detect Displays' nothing happens.

Hardware :: Connecting MacBook Pro (mini Displayport) To TV?

May 3, 2009

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?

MacBook Pro :: Mini Displayport + Audio - Final Verdict?

Jul 2, 2009

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?

MacBook Pro :: Mini DisplayPort To VGA Adapter Troubleshooting?

Mar 16, 2010

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.

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.

MacBook Pro :: Finding Mini Displayport To HDMI Cables With Audio

Jun 6, 2010

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.

Has anyone seen them available online?

MacBook Pro :: Mini Displayport Can't Detect External Monitor

May 28, 2012

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

MacBook Pro :: External Monitor / Mini Displayport Stopped Working On MBP

Jun 29, 2009

I have a 15" unibody MBP bought in Nov '08.

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!

MacBook Pro :: Finding Hdmi Or Mini Displayport To Cat5 Video Converter

Apr 15, 2010

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.

MacBook Pro :: Mini DisplayPort Stopped Working After Liquid Spill - Options?

Apr 28, 2012

So I spilled a small amount of tea on the left hand side of my MacBook Pro a few weeks ago.  I immediately disconnected the power adaptor, forced shut down and placed the laptop level in a warm, dry area for several days to dry out.  On boot up everything performed normally, and has done since, except that when I tried to connect my laptop to my TV last week, nothing happened.  I use a Mini DisplayPort to VGA adaptor and normal VGA cable to connect to my tv, and have done this many times before with no issues.  The laptop normally automatically recognises that an external display is connected and outputs a video signal - an extended display under OSX Snow Lion, or a mirrored display under Windows 7 Ultimate x64 running in Boot Camp - now literally nothing happens, the laptop does not seem to recognise or react to the fact that the display is connected, and no video signal is output. 

My laptop is covered under AppleCare, but I realise that, as this is almost certainly liquid damage, there is probably little that can be done to have this fixed on my AppleCare.  What are my options?  I don't wish to pay out of pocket for what could potentially be a costly repair, but if there is a possibility to get the Mini DisplayPort working again I would like to explore it.

MacBook Pro :: Connecting To Monitor Via Mini Displayport And A VGA Adapter - Intermittent?

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.

MacBook Pro :: Purple Haze On Screen - Mini Displayport Connected To VGA Adapter?

Jan 27, 2010

I just hooked the cable up, and I get the standard Purple Haze in space desktop that I have on my Macbook, but nothing else. No icons, no toolbars, nothing. The only time I was able to get anything to come up on my larger screen was when I went into Preferences, and Desktop and Screensaver. When I click on that, I did get a box to show up on my larger screen, listed as the Secondary Desktop.

How exactly do I get the larger screen to serve as my main screen? When I close up my laptop,the larger screen goes blank. I have no idea what to do, please help!

Another question I have is how the screen will look once I do actually get it to work. The reason why I ask that is because my larger screen is an old 17" Dell, the old 4:3 box kind. I plan on upgrading to a 20" plus HD display in the near future, but cannot at the moment, so the current 17" will have to do.

Anyhow, just curious if the screen is going to be completely wonky looking given the resolution that my Macbook will be feeding it?

Mac Mini :: Second Display Detected But No Signal

Jan 7, 2011

I have a 2009 model of Mac Mini and I have a 32" Samsung TV as the primary display hooked up though MiniDVI converted to VGA and it works properly. But my second Sony 19" monitor hooked up though DisplayPort Converted to VGA does not receive signal. It is detected by Display but no signal is being sent to it. When I have only the monitor though the DisplayPort hooked up it doesn't receive signal but when I have one only though the MiniDVI it displays fine so I know its not the Monitors.

Mac Mini :: Unable To Get Video Signal

Mar 16, 2009

I received my new mac mini last week and installed a few things on it over the weekend so that I can run it as an HTPC. Works great but I am having one issue and that is with the video signal. I have the mac mini connected to my Samsung 720p LCD TV with VGA using Apple's miniport to vga adaptor.

When the TV is already turned on and I start the mini or bring the mini out of sleep then everything works OK. However if the TV is off and I start the mini or bring it out of sleep and then turn on the TV, I get a "no video signal" message.

MacBook Pro :: Mini DisplayPort To VGA Adapter Won't Work On Thunderbolt Port

Jul 3, 2012

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.

Mac Mini :: Does Not Boot, No Video Signal, No Chime

Feb 2, 2012

My mini "starts" without chime when I press the power button on the back. The fan starts, the light in front goes on and I hear some clicks which could be the hard drive. The screen remains black (no signal) and the mini does not respond to the USB keyboard power button. It does not start when pressing it and will not power down if I press it for any length of time when it is on. Pressing the power button on the back for some time shuts it down.

Mac Mini :: Display Signal Turns Off Without Warning?

Jun 16, 2012

I have MacMini and the display signal turns off intermittently (i.e. not just sleeping). 

The display is via a VGA connection to a Philips monitor (although I've tried with an Acer VGA monitor too and get the same problem). 

The only way to fix it seems to be to turn the Mac off and on again. 

I feel pretty disappointed. I've used Apple Macs since having a Mac Plus 20 years ago and have always recommended people to use them because "you just plug things in and they work"... 

But this is simply rubbish. It's practically useless. should I just try to get my money back under the "not fit for purpose" clause in the sale of goods act.

I have a Mini Displayport to DVI adapter hooked up to a DVI -VGA adapter which leads to the display. I haven't got it to work yet. I have followed advice about closing the lid and using usb mouse and keyboard with no luck. The only thing that happens is that the screen on the laptop flashes blue for about a second after plugging in the Mini DisplayPort adapter.

Mac Mini :: Can't Get Multiple Devices To Connect To Wireless Signal

Mar 28, 2012

I just got a Mac Mini no too long ago and while moving to my new apartment, my wireless router had a tragic accident and is no longer with me. So I thought "hey, I will just use my Mac Mini to broadcast a wifi signal so my other devices can connect to it." So I spent the morning setting up the internet sharing in the Mac Mini system preferences. Got my Dell Studio 1555 to connect with no issues. But my roommates acer notebook won't pick up the wifi signal at all. Checked it on both of our smart phones (both are android models), my nook, and even my ipod touch. It is only showing up on the dell for some reason. I was wondering if anyone else has encoutered this issue before Mac mini is currently set up with 128bit wep with a 13 character password.

Hardware :: Mini Displayport To Dvi To Vga?

I got a mini displayport to dvi adapter for my macbook pro 13". Then I have one of those dvi to vga converters (URL) that i used to use w/ my old desktop.

Will that work ok on top of the displayport to dvi adapter? I tried it on my tv (which only has vga and hdmi, no dvi) and it recognizes the display but I only get a black screen. I've had problems setting the tv up properly in the past, so it could just be the TV. I wanted to rule out it being the vga adapter though.

Desktops :: Using Mini DisplayPort To VGA With A Samsung Monitor

Mar 14, 2009

I have the standard 13" aluminum macbook, and I was looking into getting the 'Mini DisplayPort to VGA' adapter to connect my 22" Samsung monitor. On the Apple website, I have seen nothing but horrible reviews about the connection cable, saying that it exclusively does not work with Samsung brand monitors and TV's. On the other hand I only see good things about it connecting to other devices and monitors.

Can anyone shed any light on this? It's already ridiculous that i have to pay the 30$ price for this cable just to use an external monitor, the least I can do is know that it will for sure work.
