Connecting iMac to VGA projector problems

I have just connected my Mac to a new NEC VGA projector via thundertbolt with thunderbolt-VGA adapter. Even though I have done evrything that's recommended for the display differences in both the mac and the projector, the image remains poor, blurry, with a overall fuchsia tint.
What should I do?

The Mini DisplayPort to VGA adapter is what works in the Thunderbolt Port.
see > thunderbolt to VGA - Apple Store (U.S.)
Did you try a different VGA cable like I suggested...?
Did you try a different Adapter like I suggested...? If not, then take that adapter to your local AASP and have them test it.

Macbook Pro and Vga projector problem

Ok this is probably an easy question for someone clued in on apple tech.
I have a macbook pro 15 (2010) I connect to my classroom projector via a vga cable to the mini-port on the side. When the projector shows the picture it is not what i want to show, but a blank homescreen. If i go back to my macbook and drag the document or movie all the way to the right, so it is off the screen then it shows up on the projector screen. After it shows up I can use it, but have to use if from the projector screen as I can no longer see it on my computer.
Have I messed up my settings, or is this normal. I would just like to plug the projector in and see what i see on my screen on the projector screen, at the moment I can choose either edit on my mac but the class can not see it, or edit on the projector which is hard as the mouse is on the mac.
Can anyone offer a suggestion
Many thanks

I know what to do on a PC but not a macbook. Basically it sounds like your display is extending to the second screen, not duplicating (meaning what you project and what you see on your mac screen are the same)
Try to poke around in the set up slideshow or display settings of your program (keynote?) and see if there are controls for extending or duplicating the screen.
What program are you using? If there's a forum for it I can ask the hosts to move this to the specific forum and see if it can get you a more precise answer faster. Or we can just get them to move it to the macbook forum.

Macbook mini-dvi -- VGA projector problems

Hi
At the school i teach at we have problems hooking up our new macbooks to one of our projectors. We use a mini-dvi --> VGA cable to hook up the projector. The mac recognises the projector and it gets listed under screens, the resolution also changes. But no picture is beeing projected by the projector.
If we use a mini-dvi --> s/video/rca cable it works fine, but the quality of the picture is too low. The projector works nicely with the older macs we have, wich use the mini-dv --> vga cable.
Any toughts on what may be the problem, or what we could try?

I am having the same problem. I have to do powerpoint presentations at college and it was so embarrassing to go up there and my macbook not sync up. It use to work. I even bought a new adapter. It did not fix the problem. All the windows laptops were able to sync up to the projector but mine did not. This one one of the main reasons I bought a macbook. I need to take my work to school and connect to projectors. I am using the mini-DVI to VGA adapter. There appears to be no physical damage. When I click detect displays nothing happens. Now I have to redo everything on windows. Please, I hope someone has a fix for this. I am using the following; 2 GHZ Intel Core 2 DUo, 1 GB RAM, Mac OS X 10.4.10

Santa Rosa MBP - DVI to VGA Projector problems

When hooking up a Sharp PG M20X using a [DVI toVGA cable] and a [VGA to DVI adaptor] the MBP sees the projector, but the projector cannot see the computer.
This is a problem because, I may find myself in situations where this is the only configuration for hooking my MBP up to a projector.
Note:
1. A G4 Powerbook works fine with this configuration.
2. The MacBook Pro drives the Sharp PG M20X projector DVI to DVI - without problems
3. The MacBook Pro drives a DVI to VGA CRT monitor - using a [VGA to DVI adaptor] - without problems.
Is there a solution?
Thanks
I have a 2.4 GHz Santa Rosa C2D MacBook Pro Mac OS X (10.4.10) Sharp PG M20X Projector (DVI-input)

I think I solved this problem.
It was in issue for me. My second monitor would only display the Windows XP screen when it was loading, then it would black out. I couldn't even move my mouse arrow to the other side. Then I fixed it, here's how (running Windows XP SP3):
1. Start > Control Panel > Appearance and Themes
2. Display
3. Go to tab "settings"
4. Double click the blue image with the "2" inside it. This is the second monitor, adjacent to your first, or primary, monitor. The blue box may be a desaturated, greyish blue, meaning that the monitor is disabled. Click it and it a box will pop up asking if you want to enable the monitor. Click OK, and then like magic, your monitor is resurected in it's Windows Glory! From there, adjust the resolution, and it should work perfectly.
This isn't a Boot Camp compatability issue, it's just a problem with the lack of familiarity that users of OS X have with using XP.
Have a nice day!

Is there a way to connect a VGA projector to my 27" iMac?

There doesn't seem to be any kind of mini display port on my 27" iMac. Anyone know how I can connect to a VGA projector?

If it's a new iMac it has a Thunderbolt port with a lightning bolt icon. You can plug a mini-display port VGA adapter into it. If it doesn't have a Thunderbolt it has the same shaped port with a little computer monitor looking icon (I think). Then use same VGA adapter and VGA cable.
Your sig says G5 but that can't be right if you have a 27" so please update your profile. Which model iMac do you have?

MBP freezes when connected to VGA projector

My MacBook Pro (15" 2.4Ghz SR, 4Gb) freezes when connected to a VGA projector, doesn't matter whether the DVI-VGA adapter is connected to cable first or last. Boot time while connected to the projector is also inordinately long. I have seen this happen a number of times specifically with other Santa Rosa MBPs.
I haven't called Apple yet on this and I suspect it will require a firmware update to fix; is this a known issue (and is it known to apple?)
thanks
--p

Just to update this thread with what I've posted elsewhere:
On my machine this problem only happens if the computer has been put to sleep before being connected to a projector. That is, put to sleep after being booted but before connection to the computer. It can be connected after booting without sleep. Once it has been successfully connected to a projector, it can be disconnected, put to sleep, awakened and reconnected with no problem.
I think that this "first sleep after boot" issue is what makes the occurrence of this problem so variable.
Some people just leave their computer on for long periods, only putting it to sleep when not using it. If they connected to a projector before putting it to sleep the first time they wouldn't see this problem.

Vga projector

I am running 10.8.2 on a 2011 macbook air. I updated a few weeks ago and since then have not been able to connect to a vga projector. This has caused me all sorts of problems since I need to use a projector daily.

What type of cabe are you using to connect to it? Have you tried also https://itunes.apple.com/us/app/display-menu/id549083868?mt=12 because i have not had any problems connecting mine to a projector.

I have a new Imac and connected a VGA projector

We have a new imac and have connected it to a VGA projector and have purchased a mini VGA convertor cable from the apple store, but now it changes the resolution once you change monitor in the system folder to mirrow. This is the only way we can get it to work. This there a problem with OS Lion.

You can disable it as a desktop in System Preferences > MIssion control > uncheck "Show Dashboard as a space".

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

Apple has a minidisplay to vga adapter which i'm assuming will work.
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.
Is there any other way to link these two devices up? Component switch or wireless transmitter?
The best connection you can make with the powerlite 77c is through VGA.

I have purchased the VGA Connectors for both a iMac and Macbook Pro so that i can connect my promethean board projector to the computer and I can not get the image on the screen. Does anyone have any suggestions?

thank you, I have the adaptors so glad that would work. I just heard adaptors burn out often. So Just thought for my main iMac computer, a plug would be best. I will get one once I move.
Any other suggestions or things I should know about apple products in Ireland. I know there are no Apple stores there.
An adaptor doesn't burn out. It merely serves as a means to connect the power prongs on your device to the power supply.
I believe you are thinking of a transformer, which you do not need. A transformer converts one voltage to another.
You don't need to do that as the power supply of modern electronics can take almost any worldwide voltage.
Look at the label on the device. It should indicate the input power acceptable of 100-240 VAC, 50-60 Hz.
Additionally, I found the adapters cheaper in the UK than I found them in the US. They were available in most supermarket chains. I wasn't in Ireland, so I can't say one way or the other.
If you have something that doesn't have that input power spec, it would require a transformer.
On other items like electric clocks or things with motors, you can connect them up to a transformer and the voltage will be correct, but the frequency may not. For clocks, that will cause them to not keep time well. For motors, they will burn out.

Can't connect MBP to LCD projector using DVI-TO-VGA adapter

I am trying to connect my MacBookPro to a Hitachi CP-X885 projector, which I normally connect an IBM Thinkpad to at 800x600 or 1024x768. I also use my MBP and the VGA adapter to connect to other LCD projectors and monitors (so my adapter works, as well as both systems, projector, cables, etc.). Problem is, that when I connect my MBP to the projector (I have to connect it via VGA as there is a 250 foot cable that goes to the front where the rear-projection takes place). When I do the "detect displays" nothing is detected. I also connected directly to the projector using a shorter cable, same thing (doesn't detect it). So, is the projector not supplying some type of signal to the output, that the MBP wants to see?)... is there a way to FORCE the MPB to have output? I know that if there is signal, it will display (we have LOTS of notebooks that display to the projector just fine, BUT have SEVERAL MBP's, and NONE of them will detect, and we've tried several adapters (just to be sure)... HELP!... is there some way to FORCE output from the MBP instead of it having to DETECT IT???
Thanks!

Sorry Walter, but according to the Terms of Use (which you agreed to the first time you logged in to the Discussions and can be found if you click on the "Help" link to the right):
Do not post a URL unless it directly answers a user's question.
The URL you post does not answer David's original question. Also, it could potentially void his warranty because a firmware hack (and this is indeed a link to a "hack") is an unauthorized alteration to the hardware of his computer. ("Software" can only be installed on the hard drive and that hack is not installed on the hard drive, it's installed on the firmware on a chip inside the logic board.)
I don't want to take this thread off-topic, but your reply does NOT help David's situation. I would, however, value your input and anyone else's to this and any other topic in the Discussions as long as it is pertinent to the original subject.

Connecting MAC Air to Projector - which is better, hdmi, vga or usb?

Connecting MAC Air to Projector - which is better, hdmi, vga or usb?

HDMI is thje preferred digital replacemnt for older analog video standards, which your other choices use. It offers far higher signal and definition quality.
Apple has an adapter that is used with your Thunderbolt port/ Mini DisplayPort, if yours is equipped as such.
I've not had a problem with this. It is a Belkin.

External VGA Projector Screen Blue when MacBook Pro Connected

I love using my laptop for Powerpoint and Keynote presentations at work. I used to have a Powerbook 1.5GHz 15" and now have a MacBook Pro 2.2GHz 15". With some external VGA projectors, after connecting the MacBook Pro, everything works great. I turn off mirroring and my presentation goes smoothly.
However, with some particular external VGA projectors, I get a connection problem. After using my DVI-to-VGA cable to connect my MBP to the projector, nothing happens. The projector continues to project a blue screen as though nothing is connected to it and as though it has no video source. I've cycled through the projectors input selections hoping the projector would find the signal but still nothing. I've even restarted my MBP with the cables attached to the projector and still the projector shows a blue screen.
My friends can connect their PC Windows XP and Windows Vista computers to this same projector with no problems. I used to have this same problem with my PowerBook G4 which is one of the reasons I upgraded to the new MBP hoping this problem would be resolved. What's wrong and what can I do to get my MBP compatible with the external projector?

Sorry, I meant the cable that links between the connector and the input to the projector (RGB - IN by the way, not OUT).
We have a number of these VGA cables at my place of work that will work with a PC but not a Mac. Some are fine. My technician holds on to a cable for me that we know works and if I get a bad one, he brings in the replacement and it takes a few seconds to go online. I also note that some of the projectors (particularly ceiling mounted ones) have an additional adapter between the cable and the projector. It may be that some of the pins are not connected.
Of course, if the projector is mounted too high, that would not allow easy replacement.
I would suggest finding a cable that works and carrying that around.

How to connect the iPad to a VGA projector

I read the comments about using the iPad with a VGA projector for presentations, but those were for the original iPad. My association is asking me to present a live demonstration of the new iPad 2. I tested the iPad 2 with the digital connector to HDMI on my TV and that works great. I can move around all the screens on my iPad and even play Angry Birds.
But what about connecting this iPad 2 to a VGA projector? All the earlier comments referred to that process as "very limited" with only a few apps running on it, like Keynote. That won't do for my presentation. Is there a solution or does the new iPad 2 fully support a standard (read old) VGA projector?
Thank you for your replies.
Jean Feuillet

It is my understanding that the dgital adapter will give you full video mirroring over HDMI from the iPad 2, although there are some reported models of TVs and projectors that have issues, but that analog signaling, such as VGA, is limited to apps specifically written to provide access to that type of video connection.

Not sure that I have selected the correct forum. Hope my questions are clearly stated.
Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter. TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices). It does not show Mail or Safari menus. System preferences' display "gathered" the Samsung and chose its resolution. I did not find a way to select the Samsung as my display.
In addition to having old hardware, we have Verizon FIOS providing internet and TV access. Is there any way to make this work for us? We would like to stream video (Netflix) and view shows from the Web. Do we need Apple TV to do this? Or is it not possible with our old iMac? My husband thinks that our Airport could be a factor.
Thank you

Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
There are, actually, many alternatives to choose from than just from a Mac.
You need to have or invest in a WiFi capable router for all of these examples.
Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
If you have a older Mac, like I have noticed many users do, then you have other options.
If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time, you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.
