Connect iMac MiniDisplay port to VGA or composite projector, PLEASE!??

I have an iMac and an Epson Powerlite 77c projector I am wanting to link up. I need to go from the minidisplay port in the back of the imac to either composite or vga (female) connection. Apple has a minidisplay to vga adapter which i'm assuming will work.
Epson Projector connections - VGA (female,) Video and audio in (composite), S-video
iMac display connections- Mini display port
Would it be better to use vga or composite for watching movies and using the computer through the projector?
And...if i am thinking of the correct cable i'm also going to need an extension to actually get to the monitor. Since the minidisplay to vga cable is female and so is the vga input on the projector, Is there such thing as male-male vga cable and would it send the signal properly from the imac to the projector?
Is there any other way to link these two devices up? Component switch or wireless transmitter?
Thanks

Yes, it will work fine!
Would it be better to use vga or composite for watching movies and using the computer through the projector?
The iMac is not able to connect via composite cable at all. VGA, Mini Display Port, and HDMI (through adapter) are the only types of cabling that will work. Keep in mind that composite is the absolute WORST video quality you could hope for. Here is the scale from worst to best...
Composite, S Video, Component, VGA, DVI/HDMI/MDP (these last 3 are essentially the same quality)
Is there such thing as male-male vga cable and would it send the signal properly from the imac to the projector?
Yes, they are extremely common, and it will work fine. I would be surprised if there wasn't an extra cable of this sort already in the projector bag. It is standard gear for all of my office's projector sets.

The best connection you can make with the powerlite 77c is through VGA.

Minidisplay port to VGA problems.

I just got a minidisplay port to VGA adapter and have been trying to connect it to my samsung lcd TV with no joy. What do I need to do?
The TV obviously has a VGA connection on the back but in the menus it seems not to be highlighted as if there was no signal coming through.

I've bought an USB-to-ethernet-adapter and a minidisplay-port-to-VGA-adapter. But I can't use them at same time. At first, I plugged those two adapters and only the USB-to-ethernet worked. Tried restarting the mac then only VGA adapter worked.

Thanks Malcolm - Do you think it might be worth trying to flash the firmware on these cases - there seem to be updaters available on Prolific's website. Obviously I'd have to do it on a PC. I've emailed Prolific asking them about my problem. No reply as yet, and I'm not holding my breath! Do you know if there are any other posts on these boards relating to Prolific? Stupid question really - I'll just do a search...
Thanks again for your post. Cheers from Bonnie Scotland.

When I connect my Mac Mini 2011 with Lion to a TV via HDMI and an earphone cable is plugged in, it´s not possible to choose sound out via hdmi, as opposed to connection via minidisplay port. Anybody knows how to fix this?

Was just on the phone with Apple about this.
The solution was as follows for me anyway...
Go to your Finder
Choose the Go Menu
Choose Computer
Choose your Macintosh Hard Drive
Choose your "Library" Folder
Choose the "Preferences" Folder
There should be a folder called "Audio"
Move that whole folder to the trash
Empty the Trash
Restart from the Apple Menu
When you are back up and running;
     Choose System Preferences from the Apple Menu
     Choose Sound
      In the output tab you should now be able to make the HDMI "Sticky"
      Enjoy your sound over HDMI and no more dirty knees or broken backs unplugging the desktop speakers!

IMac MiniDisplay Port 2nd Monitor Setup

Looking for advance on setting up a second monitor. My current arrangement is unique in that I currently use my iMac as an external display for my dock HP Laptop via a Displayport to MiniDisplay port cable.
So when I use my docked laptop I have two monitors, one is the iMac and the other is an HP LCD monitor connected via DVI.
What i would like to do is have the HP monitor serve as my iMac's external monitor when I'm not using the laptop. It has an HDMI input, so I've ordered a miniDisplayport to HDMI cable...
What i'm looking for is a switch that would allow me to either manually switch the iMac into the Laptop's external display OR automatically switch when it sees a signal coming from the laptop dock.
I think this would be a MiniDisplay port switch that would allow for two way video.
Any one out there try this?

Hi John,
I really have no idea, but as a test, hold alt key at cold startup, let it set on that screen for maybe a minute or two, then click the startup volume or hit enter... any change?
Also, if you log out & back in does it show up?

IMac miniDisplay Port and USB headset

I have recently purchased the Belkin AV360 in order to use my PS3 on my iMac 27".
It works just fine, both video and sound, but I would like to have the sound output to my USB headset if possible.
When I plug in the USB headset, it continues to output sound from the operating system rather than the video that is being displayed from the miniDisplay Port. I assume that by using an analog headset might fix this but I would prefer not to spend more money on another headset if i am not forced to.
So, does anyone know if it is possible to get a USB headset to play audio when in Target Mode?
as well
If I use an analog headset, would it play audio when in Target Mode?
Thanks in advance for any help/info!

Hi Patrick,
Now test with just the Hub connected, then test by adding one USB device at a time, most likely one of the USB Drives is having problems.

Does the late '09 24" iMac minidisplay port allow for video input as well as output?

Greetings,
I own a 24" 2.66 GHz Intel Core 2 Duo iMac with the Nvidia 9400 card. It's nearing the end of it's gaming life but I still want to use it for everything else after I get my new tower. Everything I can find in reguards to using an iMac as a monitor for a different computer references the 27" iMac one model newer than my current computer. Is the minidisplay port on my machine able to accept an input or am I forced to get a subpar monitor for my 2nd machine? Thanks!
~Dan

Only the 27" can be used in target display mode.

HT3382 What if I want to connect the minidisplay port of a mac book air with the minidisplay port of a monitor? Can I use a the thunderbolt cable to do this connections?

Using mac book air (late 2010) minidisplay port and minidisplay port of monitor Monitor Dell UltraSharp de 23.8" Widescreen U2414H.
Can I connect them using a thunderbolt cable or is there a specific cable I can use to stablish this connection?
Thanks

A Thunderbolt cable won't work. Use a Mini DisplayPort to Mini DisplayPort, or Mini DisplayPort to DisplayPort, cable.

(If you use DisplayPort, make sure you use the Input, not Output, port on the display.)

How to connect iMAC thunderbolt port to a cable TV set top box?

I am moving to a house that will have combination TV-phone-Internet services delivered via cable (Optimum is the provider). I understand that with my new iMac which has a "thunderbolt" port that I can use the iMac as a tv monitor and DVR (recorder) and watch live TV or recorded TV. I think it is possible to record TV shows either on the iMac's hard drive or the Optimum DVR. Beyond that, I get confused because I do not understand the details of RCA cables, coaxial cables, HDMI connectors, etc. Apple does not provide support for set top boxes (I called Apple), and Optimum does not provide support for Macs (I called them too). Since Apple is the party advertising the capability of watching TV on a Mac, I would think the burden is more on them to explain how that works, and maybe they have done so on their web sites, but I cannot find it so far. I can understand that the cable company does not want to tell people how to bypass the need for their DVR equipment. Before I go out and hire a consultant for a few hundred dollars to explain it, I was hoping I might find online some tips on how to set up a system at home. No luck so far.
Am I correct in assuming that wireless connections are NOT an option because a TV signal has too much bandwidth to work wirelessly? (I do have a wireless router already.)
If so and if I am using wires to connect the iMac, am I correct to think I want to use the thunderbolt port for best results?
If so, what next? What exactly is the adapter or cable I need and how do I plug it into the set top box? There are several people in the household, and so I would want the flat screen TV monitor to work normally at times rather than only use the iMac. Does that require several set top boxes? I would think that this would be an issue for many people, and it seems to me that this forum would be an ideal place to get help. So far the people I have spoken with say "well it depends on what you want to do and what your equipment is and for that you have to go ask ___________[someone else]"

I do not understand what Apple TV is. I have TV already. When I look up "Apple TV" on the Apple website I see that is has been redesigned to be small in size but big in entertainment. Since I did not know what it was BEFORE it was redesigned, knowing that is has been redesigned does not help me understand it. Now it is smaller? So it was too big before? "Watch Netflix titles instantly." But I can do that with my mac and an internet connection now. So what is Apple TV that makes it a better or different way to watch Netflix movies? "Best of all, Apple TV is just $99" Sorry, but how is that the Best of All part? My Optimum Cable is charging me $30 a month for TV. But Apple TV's best part is it costs $99? Is that per month too? I also see that everything streams wirelessly to Apple TV, and all I need it so connect apple tv to my widescreen TV using an HDMI cable sold separately. Now I am really confused. I plug in a cable to get wireless streaming? If it is wireless, why does it need a cable? If there is a cable involved, how is it wireless? Color me clueless. I cannot find a straight forward description of what Apple TV is. And so I don't get how that is the answer to my question. Sorry for being so simple-minded. Thanks for the suggestion and I will go research further to learn what is an Apple TV.

I have a MBP Retina LCD (resolution 2880x1800) and in the office I use it with a Monitor Sony LMD-2450W connected by VGA. After installing 10.9.2 the resolution in the monitor has been downsized to 4:3 (and 1280x960) instead of its 16:9 display. Anyone know how can I change the resolution manually?
Display shows only 3 different resolution if I choose "scaled" but none use the full area of the monitor.
Thank you
Marco

This has been an ongoing problem with external monitors that predates 10.9.2. I wrote various tips on different methods here, though the best is probably the hot corner one:

Why does my Vizio hdtv say no signal when I connect my minidisplay port to hdmi cord between my macbook pro and tv?

My Vizio hdtv says "No Signal" when I use my mini displayport to hdmi cord. It worked flawlessly for a month but randomly decided to no longer work.
I am using a macbook pro from early 2011 running os x Lion 10.7.5 and a thunderbolt to hdmi cord. The cord has worked without a hitch the numerous times I've used it until recently. Now plugging it in will cause the macbook to flash blue quicker than normal and immediately go back to the normal screen. I know the macbook recognizes the TV because changing the input on the TV to the hdmi connected to the computer will cause the macbook to flash blue again, with the same result. The TV remains unresponsive. I have tried all combinations of turning on and off the TV and macbook with the cord plugged in and unpugged from either and both systems and in both hdmi inputs on the TV. I've changed the display resolution to every possible option with no result. The TV is not recognized as a display on either the Display section of System Preferences or the Sound section.
It confounds me that the cord should work flawlessly until now, a month after buying it, for no apparent reason. I've been gentle with the cord, so the problem being a result of damage is unlikely. I had not updated my computer in any way between the successful and unsuccessful uses of the cord, but I have since updated my computer and the problem remains.
I have searched for this problem on the Internet and have seen others with similar problems, but I have not found a solution that resolves my problem. I hope to avoid having to make any additional purchases.
And a thousand and one thanks to any and all who help.

Do you have gfxCardStatus installed? Is your monitor set to "Integrated" or "Discrete". You want it set to Discrete to drive the external HDMI display.
Try resetting the PRAM and SMC
<About NVRAM and PRAM>
<Intel-based Macs: Resetting the System Management Controller (SMC)>
Are you sure you have a good miniDisplayPort to HDMI cable?
Do you have another HDMI display you can test against (your neighbor's HDMI capable TV).
Do you have friend that can test the cable using their Mac and maybe their TV or a monitor that has HDMI input.

Hello! I bought a minidisplay PORT to VGA adaptor and I had two problems.

Today before my presentation I had two problems with the adaptor: first one, part of the mac`s screen was cropped and the second one, after restarting my mac, the initial screen (with the apple logo) was also cropped. And it is still this way.
Could anyone help me ? I would be really appreciated.
Regards, Guilherme.

Connecting DVI Cinema Display and VGA Projector from Minidisplay Port

Hi Everyone!
I'm trying to get my mid 2011 Mac Mini to send a signal from my MiniDisplay Port to a vga splitter which works fine. My biggest thing is that when I connect my inFocus IN112 VGA Projector the screen shows up from my mac but to connect my Cinema Display it takes VGA so I had to go from the VGA Splitter on one side and use a vga to dvi adapter and my cinema display shows blank? Help Me Please!!
Thanks,
Andrew

I already have a converter on the end of the VGA Splitter to go to the Cinema. The reason I don't use the hdmi to dvi is because with the minidisplay port using vga to the projector and the hdmi going to dvi to the Cinema it makes the projector screen very rough and pixely

Mac Pro 2008 with Radeon 4870 video useable resolution on DVI limited to size of minidisplay port VGA when displays are mirrored. Did not have this problem until I plugged in new monitor (miniDisplayport), but now it affects even going back original mon

Have been using the Mac Pro since 2008. Changed to a Radeon 4870 card early this year. Everything was fine.
Running an old KDS monitor from minidisplay port to VGA and a 1400x1050 projector from DVI out. Have used the
two mirrored the entire time with no trouble.
The old kDS monitor looked like it was starting to go bad so I got another monitor. Don't have much room
so it's a 14inchwith widescreen 1328x768 display. Hooked that to minidisplay port as it only has a VGA input.
Immediately the LCD display took over and restricted the output to the projector.
If I turn off mirroring, I can get projector back to normal. But this makes running programs a lot more difficult.
It worked fine with mirroring on before the monitor change. Except going back to old monitor,
now it is affecting things. I pull up display preferences. If the displays are mirrored, even setting the projector
to 1400x1050, it says "usuable resolution 1280x1024." It didn't use to do this at all.
Tried reseting NVRAM - no result.
Any suggestions would be helpful. Just looking at the image on the projector, I don't see any difference from
before.

UPDATE:
As noted in the first post, both of these newer USB DAC work fine at 24/96 on my wife's iMac, so it's clear that they didn't both become defective when I connected them to the Macbook Pro at the same time.
Resetting the Macbook Pro PRAM didn't help, so I removed the hard shell laptop case to get to the battery and remove it, then reset the SMC. After that I could use the original DAC at 24/96 again, but only IF it was plugged into the rear USB port. If I plugged it into the front USB port then the sound was garbled and filled with noise. This was a vast improvement over no sound at all.
Then I switched to the replacement/updated DAC, but I got no sound at all from either USB port at any bit-rate. And returning to the original DAC again now results in no sound again.
Sigh... I will reset the PRAM and SMC again, and see how far I can get with this. I'd still love some help. Thanks!
