Macbook pro Mini displayport to VGA/HDMI needs restart to work

I am having a strange problem. I have an original Apple mini DisplayPort to VGA adapter and one non-apple mini-displayport to HDMI adapter. When I connect external monitor through either one of those it doesn't work unless i restart my computer. I tried different monitors but i see the same problem. Has anyone faced a similar problem? I checked online but didn't see any postings.
My macbook pro is relatively new (bought in april), i5 processor.

Thanks but I tried this the very first time this started happening. Didn't work

Macbook Pro mini-DisplayPort to VGA input on a VIZIO SV422XVT

I am attempting to use my Vizio SV422XVT with my MacBook Pro via the VGA input. I've followed KatanaBook's advice in this post, but I still can't get it to function correctly.
http://discussions.apple.com/message.jspa?messageID=12380071#12380071
I've created a custom resolution using SwitchResX with the parameters specified in the SV422XVT manual, but I still get a 'no signal' response on the TV.
Any help would be greatly appreciated.
Thank you.

ARiccitelli, have you tried running the [Apple Mini DisplayPort to VGA Adapter firmware update|http://support.apple.com/downloads/Mini_DisplayPort_to_VGA_FirmwareUpdate] to ensure that your adapter has the latest firmware revision?
I don’t have a Vizio monitor, so I can’t offer any advice regarding it; is your adapter known to work with other VGA-compatible monitors at your preferred color depth, resolution, and refresh rate?

Mid-2010 macbook pro mini display port to hdmi works only intermittently

I have a 13-inch mid-2010 MacBook Pro running OS X 10.10.2. HDMI out from mini displayport to my Dynex TV only intermittently works. The times that I have gotten it to work involves a combination of restarting the computer, unplugging the TV and plugging it back in, then plugging in the MDP adapter. Now when I plug it in, the MacBook screen flashes black like it is trying to detect the external display, but no picture on the TV. Any help would be appreciated.

Here is the console log output when I plug in the adapter:

Macbook air Mini DisplayPort to VGA Adapter connectivity issues

Hi pple,
Would like to ask if anyone is facing connectivity issues with Mini DisplayPort to VGA?
I am currently using the 2nd Gen Macbook Air with Intel HD Graphics 3000 384 MB. Sometimes when I connect to a montior (Viewsonic VA1918wm) it works fine, sometimes it just does not work and the laptop just shows me a blue screen.
I tried with out with my friend's Mini DisplayPort to VGA adapter, it has the same problem. Does this means that my macbook air mini disoaly port got a problem?
Thanks
Bryan

I am experiencing the same kind of problem... only with projectors. Some projectors will display the screen and then others wont even register with the MacBook Air.
Using an Apple Min Displayport to VGA adapter. It's hit or miss if it works. Firmware has been updated on the adapter but this did not help.
Anyone help with this?
Thanks,
Nathan.

Mid 2010 Macbook pro - Mini DisplayPort to Hdmi issues

Hi there! I'm having some issues connecting my mid 2010 Macbook pro to my 32" Toshiba LED TV.
I'm running OS X Version 10.8.2 , as mentioned before, on the mid 2010 Macbook pro.
The issue which I have, is that when I connect my Hdmi cable to my minidisplay port through the adapter, I keep getting a blue screen popping up.
I am using a Startech MiniDisplay to HDMI Adapter Converter and ION 6FT Flat HDMI CABLE.
anyone with suggestions on help?

I had issues with getting my MBP to work with my Vizio XVT323SV via the RGB port. What worked for me was downloading SwitchResX (http://www.madrau.com/indexSRX4.html) and setting up a custom 1920x1080 resolution using the values found in the Vizio user guide. Works like a champ now. Best shareware investment I ever made. Now I can watch my EyeTV recordings at full HD resolution.
Hope this helps. Good luck!
Sidebar: I also bought the Griffin mini-DisplayPort to HDMI adapter and an HDMI cable, but I can't get any signal at all via that connection. The Mac doesn't see the TV and the TV doesn't see a signal. Very frustrating. My RGB connection is good enough but I bet HDMI would be even better.

Macbook Pro Mini Displayport to HDMI problem Please Help!

I just bought a new Macbook Pro Core i7 15" and have it connected to a [URL="http://www.amazon.com/Samsung-P2370HD-23-Inch-1080p-Monitor/dp/B002DHS398 "]Samsung P2370HD[/URL] via a [URL="http://www.kanexlive.com/products/item-id-3689.html"]Kanex Mini Displayport to HDMI cable[/URL]. I'm running Snow Leopard 10.6.3 and have the resolution @ 1080p via system preferences and the "underscan" feathered a bit... (which I do not understand why I have to do this since I'm outputting at 1080p and the monitor accepts full 1080p as well. Can someone explain this?) however, small text is grainy, some larger bold text has a white wash behind it. Most things seem to have a slight blur as if there is a screen zoom happening just slightly. [URL="http://www.mac-forums.com/forums/apple-desktops/181687-mac-pro-samsung-ln 40b530-display.html"]As described in this similar post I found.[/URL]
My old setup was a late 2007 Macbook Pro 15" 10.6.3 connected to the same monitor I have now via Dual-Link DVI and it was crystal clear... It's hard to believe that the issue lies with Samsung, I've tried the same setup on my Sony Bravia in the living room, being that it's a much larger tv...I can't notice the artifacts as much but they are still present. Something is off.
My only other option I feel is to try a Mini Displayport to Dual-Link DVI but I chose the HDMI route for it's standardization and when I go to meetings/projections it's convenient to have one cable. Yes, I've checked cables, restarted everything ect... Can anyone help me troubleshoot this?
Thanks in advance!

Switched to a Mini Displayport to DVI cable and it works flawlessly. Still no idea, why the hdmi cable does not work properly.

MacBook Pro & Mini DisplayPort

I have been looking into options to upgrade my systems for photo editing. I'm now thinking about buying a 24 inch Apple LED Cinema Display to hook up to my MacBook Pro. My video output port is DVI (not mini-DVI). Is there an adapter I can use from my DVI to the Mini DisplayPort on the display? It is not clear from what I see in the Apple website. Also, can I plug in, and use, an external keyboard when the display is connected to the MacBook?

The discussion was started in October '08 (about 9 months) as that's when the MiniDisplay port was introduced on the Apple portable lineup. Currently, all "shipping" models from Apple come with MiniDisplay Port was the standard video out connection, the only machine capable of DVI is the Mac Pro with appropriate video card selection.
I'm sure when an adapter is made which supports "reversing" MiniDisplay Port to DVI then there will be enough topics on it. My understanding of how the technology works is that it's not possible, but the fact that there is development on it would indicate otherwise.
It reminds me of when Apple use to use their proprietary ADC hook up for their displays. I guess I had thought that with standardization of VGA & DVI we'd ok with using that for years to come. I guessed wrong on that, too.

Macbook Pro Mini Display Port To HDMI Not Connecting To Sony Bravia KDL-52XBR9 And Any HDMI TV's In My House

I have a Macbook Pro (Mid 2010) and recently purchased a mini DVI to HDMI cable. I was using it perfectly fine on my LG TV for a while but than one day I plugged it in and it just stopped working. The Macbook Pro screen would flash blue for a few seconds than return to normal as if nothing was plugged in. I tried detect displays and everything and it sill does not work. I tried it on 4 HDMI inputs on TV's in my house and none of them are working. Does anyone have any idea on what's wrong? I didn't change the settings at all. Just plugged it in than it stopped working. Anyone know whats wrong?

Hi 1,
You are far from the first to experience this issue. An SMC Reset may resolve some video issues, although this scenario is not listed; still, I would try it: http://support.apple.com/kb/HT3964

KVM switch one Cinema hd display (dvi) with macpro (dvi) and macbook pro (mini displayport)

I want to use a KVM switch to share one display with two computers.
Computer one is: MacPro 1,1 dual core 2.66 Ghz with two DVI ports.
Computer two is: MacBook Pro 4 core 2.66 GHz with one Mini Displayport.
Display is: Cinema HD Display with DVI connector.
To do that KVM switches only use (at least that is waht I found) one system either DVI or Mini Displayports
http://www.gefen.com/kvm/dproduct.jsp?prod_id=3113
DVI --> KVM SWITCH<-- DVI
                     V
               DVI (monitor)
http://www.atlona.com/Atlona-2x1-Mini-DisplayPort-KVM-Switch.html
Mini Displayport (Macpro) --> KVM SWITCH <-- Mini Displayport (Macbookpro)
                                                         V
                                                 DVI (monitor)
However what I want is:
DVI (Macpro) --> KVM SWITHCH<-- Mini Displayport (Macbookpro)
                                       V
                              DVI(monitor)
I couldn't find an existing KVM switcher that does this.
Then there is the following solution
DVI (Macpro) --> KVM SWITCH <-- ADAPTER (Mini Displayport to DVI) <-- Mini Displayport (Macbookpro)
                                    V
                            DVI(monitor)
The question is: Will this work?
I've been told that adapter behind adapter never works. Hope someone can help with this before spending money on nothing.
Thanx David

Maybe you're right just try and see if I can return the stuff if it's not working.
I won't be using a higher resolution then 1920 x 1200 however I still would buy the adapter
Mini DisplayPort to Dual-Link DVI Adapter
http://store.apple.com/us/product/MB571Z/A?fnode=MTY1NDA3Ng

However if there's still someone with experiencing the exact same thing I would be much obliged.

Does Mini DisplayPort to VGA adapter support DDC/CI?

I have a Mac Pro and a MacBook5,1.
Mac Pro is attached to a BenQ monitor which supports DDC/CI communication.
With a capable software I'm able to set brightness and contrast of the monitor without using monitor's OSD (thanks to DDC/CI communication).
If I attach the same monitor to my MacBook5,1 with VGA cable through a Mini DisplayPort to VGA adapter, DDC/CI stops working.
I'm no more able to set brightness and contrast and the app reports that monitor isn't DDC/CI capable.
I'm sure its not an issue related to the app that I'm using to set brightness and contrast. It detects correctly both of the monitor (the internal and the external one) and I'm sure that I'm sending DDC/CI commands to the external monitor and not to the internal one.
So, does Mini DisplayPort to VGA adapter support DDC/CI, and therefore passthrough its signal?
Or is it a problem of MacBook and its Mini DisplayPort which does not support DDC/CI at all? I don't think so.
I hope you can help me.
Regards
Andrea

No. Unlike DVI, which in the DVI-I configuration has both digital and analog pinouts, DisplayPort (and mini-DisplayPort) are purely digital. Mini-DP to DVI then DVI to VGA will not work. If you look carefully at the Apple Mini-DisplayPort to DVI adapter, you'll notice it's a DVI-D connector - digital pins only.
The Apple mini-DisplayPort to VGA adapter contains a digital-to-analog converter.
So, you'll have to choose. If you want VGA, get Apple's mini-DisplayPort to VGA adapter.

Mini displayport to vga issue

I am trying to connect my MBP to multiple projectors(via vga distribution amp) using the mini displayport to vga adapter. It will recognize and correctly connect to each projector individually but will not connect to all simultaneously. Have a macbook w mini dvi to vga adapter that works fine both individually and simultaneously but for some reason the MBP will not. any help would be greatly appreciated.

I bought my Mini DisplayPort to VGA Adapter last May and only had the chance to use it now for my presentation. When I connected the cord of our LCD Projector to the Mini DisplayPort to VGA Adapter, it didn't work. I thought the cable was problematic and so I used another one but it still didn't work. After my presentation, another friend used the same cable and her Mini DisplayPort to VGA Adapter for MacBook. Her Mini DisplayPort to VGA Adapter worked. She said she just connected the Mini DisplayPort to VGA Adapter to the cord of the projector and it already worked. Is my Mini DisplayPort to VGA Adapter problematic or is there something I forgot to do that's why it didn't work? It's the first time for me to use it and can I have it replaced just in case it really isn't working?

Getting a Mini DisplayPort to VGA Adapter & Monitor to Work with an Xserve

First let me say that I'm very new to Xserve's and OS X Server and any help is greatly appreciated.
I have an Xserve with a connected Mini DisplayPort to VGA Adapter and a confirmed working VGA monitor. There is also a keyboard and mouse plugged into the front USB port of the Xserve. The internal SSD has been formatted clean.
I've been trying to boot up from the optical drive on the Xserve using the 10.6 DVD. I use the front panel/system identifier button to boot up and I make sure enclosure lock is unlocked. Each time I try to boot up, the monitor stays off and the DVD is spit out.
I eventually got the DVD to stay in, and the screen showed the grey screen with black apple and the spinning black circle on the bottom. However, after a few minutes the screen turned orange in color. Using Screen Sharing, it looked fine. I tried a second VGA monitor, but that still didn't do it.
So with the DVD still in, I stay connected via Screen Sharing and begin the installation process remotely, thinking Snow Leopard will recognize the monitor eventually. Well, 10.6 is now fully installed, but still no working monitor.
I then decided to try the Mini DisplayPort to VGA Firmware Update. I download and run the installer, but it tells me, "The Updater could not find a Mini DisplayPort to VGA Adapter to update."
How can I possibly get this monitor working?
Thanks in advance.

Just ran in to this myself -- Nehalem Xserve running 10.6.2 Server with an MiniDisplayPort to VGA adapter connected to an Avocent Switchview 1000 KVM. Took the server offline to install RAM and after rebooting, no video. Oddly enough, the KVM's LEDs showed a display connected but Apple System Profiler showed no adapters connected to the video card. Nothing seemingly worked -- rebooting, shutdown/restart, and/or hot-plugging the adapter made no difference. I also tried a second MiniDisplayPort adapter to no avail.
Note that the MiniDisplayPort to VGA Firmware update had already been applied to BOTH adapters prior to this issue appearing.
What restored video output on our system: reboot from the Snow Leopard Server install media, video reappears over the adapter, and after that I can reboot from the SSD boot drive running 10.6.2 Server with video output working over the MiniDisplayPort to VGA adapter.

Mini displayport to HDMI = fine. Mini displayport to VGA = terrible on late 2011 MacBook Pro. Any ideas?

Hello,
I have a late 2011 unibody MacBook Pro. It has a real problem displaying through a projector or tv using mini displayport to VGA. I connect it to my tv at home with a mini displayport to HDMI cable and it works fine. If I have to connect through a VGA adapter/cable to a tv or projector for work the image always looks like the contrast has been turned right up and it looks awful. I have tried creating a profile, calibrating the secondary display and adjusting gamma settings but it doesn't make any difference.
If I plug my old black MacBook into the same projector/tv using VGA it works fine so I now have to take 2 laptops to work which is ridiculous. I thought it might be the adapter itself but at a recent event a colleage experienced exactly the same problem with his identical set up so I thought it might be something to do with the projectors set up at the event but I recently tried connecting to a projector at a different event and got the same results and now I'm confused. I guess it must have something to do with the adapter but not sure what.
Any help much appreciated.

You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
Refresh & sesolution are the first things to look at.
Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

What cable do I need to buy to connect my Macbook Pro (2011) to a VGA screen? I tried the "Mini DisplayPort to VGA", but apparently it doesnt fit the 2011 Pro version...

As the topic says,
What cable do I need to buy to connect my Macbook Pro (2011) to a VGA screen? I tried the "Mini DisplayPort to VGA", but apparently it doesnt fit the 2011 Pro version...
Help me out please.

Yes ... minidisplay
But what I do not like in that picture (my personal view, others may think differently), is that there is much plastic around the connectors where the cable must fit. You may ot may not be able to get the cable to *fully seat* with the adapter.
Other adapters (http://www.microcenter.com/single_product_results.phtml?product_id=0334087, yes I know this is a DVI) hve no plastic barriers to connections.
