17'macbook pro + projector
Hi all
I have late 2009 mbp 17' OS 10.8 and have purchased a digital projector with the view to play dvds / movies etc. I have mini display port to HDMI cable and when connected the image on the projector screen flickers and is not smooth? What could be the cause the cable? Do I need a mini display to HDMI convertor and a straight HDMI-HDMI cable any advise would be greatly appreciated
cheers Keith
Hi Keith Davison,
Thanks for the question. Your MacBook Pro definitely supports video signals via Mini DisplayPort to HDMI adapters (see About Mini DisplayPort to HDMI adapters). If you are experiencing issues with this connection, you can use the following resource to troubleshoot:

I have a Macbook Pro that I connect to a projector, but when I do, the icon display on my desktop goes all wonky with icons overlaping each other to the point they aren't identifiable. Any solutions? Thanks.
Try from the finder window, after you have done all the previous steps, click on a open part of the screen to bring up the finder window, view, clean up, or arrange by,which will give you a sort option.
Hope this helps.

Hey everyone.. I am thinking of purchasing a new macbook pro before getting to university but i wanted to double check on a little facts. Are the new macbook pro compatible with most of the projectors or will i have find difficulty? I am asking this questions since there will be a lot of presentations that will require me to connect my laptop to the projectors. If there is a software that make it compatible please tell me. Thanks for all the help.
Ash.I have used the MacBook Pro with projectors without any problems at all. The only thing to watch out for is remembering your DVI-VGA connector since most schools have older projectors that don't have DVI inputs. The connector comes with the computer, so it's not something you have to purchase separately; just make sure it's in your computer bag on presentation day.

When I connect my Macbook Pro (2009 model) using a Mini DisplayPort to VGA adapter to display a presentation via projector, only the top-left portion of what is displayed on my Macbook Pro's screen is displayed on the projector, as though I zoomed in on that portion of my screen. The projector is on and the adapter and the cable that connects the adapter to the projector machine is correctly connected. Any suggestions on how to fix this problem?
Hi glraczon.support,
It sounds like the external display you are using (projector) operates at a smaller resolution than your MacBook Pro. You may want to configure the display preferences in System Preferences for the external projector.
Here is an article that may help you with that process:

Is there a key on the MacBook Pro to toggle display options for a projector
I have had some difficulty getting my InFocus projector to consistently work correctly with my MacBook Pro. Is there a key on the MacBook Pro that toggles the options for projector display? There was one on my last MacBook and my previous PowerBook.
Thanks -
Dudley WarnerNo, there is no longer a key to control external display modes (it's F7 on my 1st gen MBP, but the option was removed along with the embedded numeric keypad in the Early 2008 models). There's not a substitute keyboard shortcut (with the exception of installing a macro player like Keyboard Maestro). Your main option is System Preferences > Displays (as stated, ticking the box to show Displays in the menu bar provides a helpful shortcut).

MacBook Pro cannot connect to external display (projector) under Windows
Our office has got one of those lovely new 13" MacBook Pros and we cannot figure out why it cannot connect to either of our 2 projectors with Windows 7.
We have an older MBP with NVidia graphics that connects just fine under both OS X and Windows. And this machine connects fine under Snow Leopard.
There was a recent Thunderbolt chipset update and we applied that; on the Windows side the Intel driver has been updated but nothing happens. Have also zapped the PRAM to no effect.
To add another wrinkle: I just connected the MBP to my Cinema Display and the external display shows fine in both OS X and Windows--Windows didn't even require me to go to the control panel.
This leads me to two thoughts: either it is something with the Thunderbolt to VGA adaptor (hard to believe, though, since it works for OS X) or it is something to do with the native resolution of the projector (equally hard to believe, as changing through various settings in Windows NOTHING happens on the external projector--it doesn't blink, go back or anything.)
Any ideas?I wish I could find the discussion, but I cannot.
There was a discussion about the Windows 7 driver for the Thunderbolt port. The conclusion I believe was that it only outputs digital signals, not analog.
The other conclusions were:
A USB-VGA adapter adapter bypasses this limitation because the driver is in the adapter itself and works regardless of the OSX/Windows operating system in charge.
Run Windows under VM, where OSX is in charge and can create analog output through Thunderbolt
If only I could find that thread ... -
What adapter to connect my Macbook Pro to projectors?
Hi All,
For the last year I've been using my old WIndows laptop when doing presentations out at client sites purely because it's what I was used to, and in almost every single case, the client will provide a VGA cable to plug into my laptop (which connects to the projector they provide) so it was SAFE and RELIABLE every time.
However it's gotten to the point where I'm way more comfortable with my Macbook Pro and want to know exactly what cable I shoudl take to client sites to ENSURE that I will always be able to connect to their projector. I'm wondering if it would be some sort of HDMI to VGA cable? I've noticed some mini displayport to vga cables online but I don't think my macbook has that port. Do I need it to be HDMI to 'female' VGA or male? I want to ensure I have all bases covered, because there's nothing more stressful or daunting than going to do a large presentation and being unable to connect!
Any help would be appreciated. and any other tips/advice is welcome for using a macbook for presentations with projectors etc!
I'm using MacBook Pro Retina Mid 2012 w/ OS X Mountain Lion 10.8.3
Cheers,
ManachiYour Thunderbolt ports 'double' as Mini DisplayPorts so if the projector uses VGA for an input, you could use this adapter, for example, to output from your MacBook Pro to VGA.
Monoprice has just about any adapter that you could need.
Good luck,

How to connect an infocus projector LP530 to MacBook Pro
We are trying to run slide show using an older IN focus projector (LP 530). . Our lab top is a 3 year mac book pro . It's not recognizing.
Hello Alliseeisgold2014,
Thanks for using Apple Support Communities.
Please see the troubleshooting steps below to help resolve this issue of your projector not connecting to your MacBook Pro:
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.

When I connect my Macbook Pro to my Dell DLP projector, either via cable or wirelessly, I just see a dark screen with the mouse and mouse trails only, can any one help?
jpmarkques post is a good start point, after folling his directions, you can try detect displays. Also try different rsolution and refresh rates.
Most of the projectors I have used support a 1024X768 res.
Youcan also try a pram reset if it still does not detect.
Leave theproctor connected and powered up, power down the MBP.
Power back up the MBP and hold the following keys before you hear the start up chime:
Option, command, P,R (no commas) continue to hold these keys till you hear the start up chime 2 times. -
i have a macbook pro. i want to connect it to projector and i have a minidisplay to vga adapter. i could connect my MBP to benq projector successfully and for all other displays( Monitors). but when i connect it to optoma projector, MBP detects the display as OPTOMA XGA but nothing on bigger screen. i tried changing the resolution and refresh rate also but no changes.
In my office we got benq projectors , for that it is working very well.(plug and play).
and also i want to say that there is no problem with the optoma projector seems, because all other windows laptops are working well with that.
i was struggling with this since one month. i googled it could not find anything supportive for my problem. please help me regarding this. i am new to apple. i hope there must be genius around here.

I need to know which MacBook Pro you have. Only mid-2010 and later MBP's transmit sound through MiniDisplay Port to HDMI. I have no information about the Mac Pro, so you might want to go to that Forum and ask there. -
How do I connect a 2013 Macbook Pro Retina to an Epson Power Lite 61p LCD Projector?
I am trying to attach an Epson PowerLite 61p LCD Projector to my 2013 Macbook Pro Retina, but I cannot find which type of adapter I need. I would assume whichever adapter is required it must connect via thunderbolt. However, I do not know if the required adapter is a "Mini Display Port to VGA Adapter," "Apple Mini DVI to VGA Adapter," or a "Thunderbolt to VGA Adapter." I would deeply appreciate your help and guidance. Thanks!
It does not matter whether you get an Apple adapter or a third pary one. What you have there is a Mini Displayport to VGA adapter, but as you know, your new MacBook no longer has an MDP port!
Thunderbolt to VGA adapters do not exist but there are plenty of HDMI to VGA adapters out there:

Problems connecting my MacBook Pro to a video projector
I have a MacBook Pro. I have used it many times to connect to a video projector and give presentations in my classroom. Lately, it is hit or miss concerning whether the laptop will give a signal to the computer. I can't figure out what I am doing wrong. I have followed the instructions in the MacBook guide.(Start with projector and laptop off, connect, turn on, etc. )
I am using the DVI to VGA adapter. I have also tried to use the function keys and manually tried to get it to detect displays. Can't think of what to do next. I gave up and hooked up a Windows computer and it worked.
Could it be the adapter? Does anyone have any ideas I can try? Thanks!I have problems too with some projectors and the DVI--VGA adapter that came with my MBP. The projector is recognized by the computer, but does not show any signal.
With the help of Stéphane Madrau, who has written the excellent tool SwitchResX, I found out that the projector reports that it takes digital input when I connect the MacBook Pro, but analog when I connect it to my 12" PBG4. From the DDC information (collected with SwitchResX):
MacBook Pro, DVI--VGA:
Input signal & sync:
Digital
PBG4, miniDVI--VGA:
Input signal & sync:
Analog input with: 0.700V / 0.300V
Separate Sync
Composite Sync
Given that the VGA cable is analog only, I would think that the MBP tries (or rather, does) output digital signals only, which don't make it into the VGA cable. If I find a solution I will post it here.
The clue was that the computer did not report any vertical scan frequencies for the external display, while it did so for a projector that worked.
