  • IMac no longer working with projector?

    Hi folks,
    I'm having a weird problem with my iMac (Intel dual core2 - White). All seems to have started going wrong after an upgrade to Leopard. The computer no longer recognises the projector. I know its the iMac cause it all works fine when I connect my Macbook. I'm using a MINI DV thing to VGA adapter.
    I have done an archive and reinstall twice but still not working. When I plug the lead in the imac quickly goes to the blue screen as if its changing resolution but then just goes back to normal. System prefs doesn't recognise that anything is plugged in.
    I have taken the iMac back to apple with the VGA adapter and 'sods' law it all worked fine! As soon as i get back to my school and re-connect it I get the same old problem! Is it a leopard fault or what? It all worked fine with Tiger?
    I have reset permission/repaired the disk/ and zapped the PRAM. Anyone got any ideas?
    Thanks
    Chris

    I'm having the same problem.
    I've turned up for two presentations in the last week where my new MacBook Pro did not recognise the projector. It looks like it's going to work (i.e. the laptop display blinks and alters resolution), but nothing is sent to the projector.
    At my office presentation, I managed to dig out my old PowerBook -- which worked fine (I have never, EVER had any problems with plugging displays or projectors into my PowerBook).
    But when at a conference, I had to suffer the embarrassment of moving everything to a PC laptop (which buggered the transitions, etc.)
    It looks like Apple has given up on the whole "it just works" thing.
    Its weird -- I'm not used to not being able to rely on my Apple laptop working... It's a little stressful.

  • Mirrored my imac temporarily to my video projector now can't get imac screen back to standard viewing (shows as if a side monitor is added)

       I recently mirrored my imac to project some videos.  I now want to return my imac to regular use and standard screen presentation but find it remains in the mode as if i have an external monitor connected to it with the monitor on the right side.  My imac screen only shows roughly 2/3 of the image, as if there is another monitor connected to the right side.  I've disconnected the projector, tried turning mirroring off, searching for displays, putting the computer to sleep.  I keep getting this same visual set up.
      Thanks for any assistance.

    Thank you Malcolm for the response. An excellent idea which I hadn't tried.
    I actually had zapped the PRAM several times (and even reset PMU) but did not think to do it with the DVI->VGA adaptor removed, so I just tried this. Unfortunately this didn't solve it. After removing the DVI-> VGA adaptor from port 2 and zapping PRAM (twice), I now am getting an "unsupported input" message on the monitor connected to Port 1 with the DVI->VGA adaptor still removed from port 2. So if anything this state is worse.
    This is very strange--because when I put the DVI adaptor back on port 2, the situation returns to where it was before as described. After a hardware reboot I have the aqua screen with missing login window again. It seems zapping the PRAM did not do it here. It also seems this DVI->VGA adaptor is definitely having an effect on the situation. Why would connecting a DVI-VGA adaptor on port two cause port one to regain function and why would removing it cause port 2 to go dead essentially?
    At any rate, I am still unable to use the computer...

  • Help, 27" iMac won't detect Epson projector

    Hello,
    I'm trying to connect a 27" to Epson projector via Mini Display to VGA adapter connected through VGA cable to the projector (that works fine with other pc)...the iMac doesn't detect it....
    Thanks

    This has been a big pain. I got the machine back, started it at the shop and it "seemed" ok. When I got it home, after 30 minutes or so, the same problems came back. Another call to applecare, and a new case number was issued to replace the hard drive. New HD in, got the machine home, and the mouse wouldn't work! I could move the cursor, but not select anything. Sometimes during the restarts I could select things, the next time I couldn't, sometimes I could on one user account and not on another. New call to applecare, new case number, many things tried, but ended up re-installing the OS. So far it seems to work okay, BUT there is something weird going on with Mail.
    As soon as it is started it basically consumes all the system memory. I can watch the available memory disappear in activity monitor where it says Mail is using nearly 100% of the CPU. If I go in to preferences-advanced in Mail and disable the account, it stops eating up resources.
    Any clues to what is going on??
    thanks

  • 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 2011 to Benq W1100 projector over a 15m cable

    I want to connect my shiny new imac 27" 3.1 GHz intel core i5 to my benq w1100 projector. I have a pipe already in the wall/celling from mac to living room. the pipe has an inner diameter of 20mm. the length of the cable has to be approximately 15m. i want to maitain the highest possible resolution. audio is not required. What is the best solution for me?

    What is the resolution of the projector?  If greater than 1920 x 1200 you need a dual link dvi adapter?
    OLD Mac Book Pro 17" > DVI port > DVI cable > projector = WORKS!
    Based on my theory I assume that the dvi port on that macbook pro is dual link.

  • Imac not detecting projector through bnc cable

    I can not get the imac to output the resolution needed for the projectors. I need a way to force the imac to output 1280 x 800 to the VGA display. We have numerous locations where this is an issue. We do not have the luxury of running straight VGA cables to the projectors, thus the imac can not recognize the projectors. Please advise, how to make the imac function fluidly without detecting the projector.

    Welcome to the Apple Discussions!
    You might try capturing the projector's EDID with this device and then using it to notify the iMac to what display device it is connected;
    http://www.gefen.com/kvm/dproduct.jsp?prod_id=4714
    UPDATE - On closer look I see that this device appears to be DVI only. I have searched the developer's site but cannot find a similar device for VGA. Perhaps a phone call to the developer would alert you to a solution.

  • IMac 27" (Late 2009): getting audio to HDMI receiver via mini DisplayPort

    I just got my first iMac 27" and I'm in the process of integrating it into my home theater system. Here is my setup:
    iMac 27" connected to HDMI receiver (Yamaha RX-V1800) via mini DosplayPort, using miniDP-to-HDMI adapter + HDMI cable
    Optoma HD20 video projector connected to HDMI receiver (HDMI out) via HDMI cable
    I have Windows 7 installed via Bootcamp 3.2, so that I can take advantage of Windows Media Center. With the above setup, I am not getting audio or video signal to my receiver and video projector when I'm using Windows 7. However, when I am in OS X environment, I can get both video and audio signal to my receiver and video projector, and either mirror or extend my video diplay. When I do plug in my iMac straight into my video projector or LCD monitor with built-in speakers while in Windows 7, I get both audio and video output. So why doesn't it work -- and only under Windows 7 -- when the signal goes through the receiver?
    My immediate thought was that it must be something about the receiver, but since the setup creates no problem under OS X I don't think it is. Could it perhaps be the Windows driver for mini DisplayPort, because it looks like iMac is not 'recognizing' my receiver and therefore not establishing connection? Is there a driver of fix available that takes care of this problem?
    Thanks!

    I've tried a few times and it hasn't worked so far...
    23" Cinema Display (ADC) connected to Apple's ADC to DVI adapter/power box then connected to Apple's DVI to mini Display Port adapter.
    Trying to output extended desktop from iMac to 23" Cinema Display.
    No signal or anything on the 2nd monitor so far.
    USB port on Cinema Display works with the setup.
    Checked system updates and all up to date as of 01-10-2010.

  • IMac mini displayport blank display on boot

    I work in a school and we use iMacs as classroom machines for teachers. The iMacs are plugged in to vga projectors and are setup to clone in Windows. This worked fine on all our iMacs with mini dvi ports. We've just bought two lots of new iMacs with mini displayport connectors. The first lot came requiring a firmware update, the second lot were already up to date. The first lot seem to have issues where they forget that the projector is connected. The only way to get them to recognise the projector again is to unplug and replug the adaptor. This is a minor annoyance but tolerable - although the old dvi port iMacs just pick up the projector and adjust the resolution automatically. The second lot which came with the most recent firmware pre-installed seem to get stuck booting Windows when the displayport to vga adaptor is plugged in. It gets to the black screen (before the Windows logo appears) and then stops. Pressing enter seems to get it past this and continue the boot process - as if it needs some kind of user input. This is more of an annoyance because it makes doing updates remotely which require a reboot impossible and expecting staff to remember to boot their computers without the adaptor plugged in seems a bit ridiculous. I've tried updating to the latest NVIDIA drivers but the problem persists. Has anybody experienced this and does anybody have a solution?

    So this is weird, playing around with the brightness controls seems to have fixed the problem - And yes I did try that yesterday but for some reason today that did the trick.

  • Windows open on projector - have to unplug.

    This is driving me nuts.  I have my classroom imac connected to an epson projector.  When I want to share the screen (mountain lion) I mirror the displays.  When I want to use my computer at its native resolution, or want privacy I unmirror the displays.  I often have the projector powered off, and the imac connected to it.  However many applications (have not yet detected a pattern - seems random) open their windows on the POWERED DOWN projector.  The only way I have found to gather them so I can use them is to disconnect the display.  This is a pain, as I am constantly fiddling with cords on the back of the mac during my day.
    Is there anyway to get the mac to ignore the projector (powered off) even when connected?
    Yes the imac is primary in the displays prefererences.  (ie title bar appears on my mac, not the projector). 
    Even an app that gathers wind

    Hi Brian, might try this...
    On Lion you can toggle Mirror Displays using fn+Cmd+F1 (provided you are using the media control keys as default).
    Or a couple of AppleScripts...

  • Connecting with projector

    Hello! I hope someone can help me with the problem..
    I am trying to connect my IMAC G5 with a video projector.
    I have been doing this for years with i book G4, using video adaptor,
    and it has always worked.
    This time, however, when I connect the projector with my IMAC,
    (the 17 inch) the resolution changes to 1024-640, thus the image on the screen
    get "swollen"..
    Even if I try to change the resolution in the system preference panel,
    (Display window), it just doesn't work out; if I change it to 1670 resolution
    as it should be, the image becomes "smaller" with a black frame around it.
    (In this case, the swollen image gets slim as before.)
    I had doubt that the video adaptor is not the right one.
    (According to the guy in the computer shop in Turin, it is Mini-VGA
    and it should work out OK likewise with Imac G5)
    I tried with a computer adaptor, too, that came with Ibook, but it is the same.
    The Mac technical assistance says that there is something wrong with my IMAC and I should take it to the repair.
    Is it really only the solution? or is there something else that I can try?
    Thank you grazie..

    Hi, did you get this solved. We also you ProPresenter. I am not sure why you mirrored the screen to get a DVD to play? PP supports DVD playback (unless your using an older version that doesnt have this feature??). Or you can drag the DVD window to the projector display.
    Did you deselect mirror image? because you wont have any arrangement options available, you wouldn’t need them.

  • Video Projector Problems

    I have our iMac connected to a large projector. The projector is acting up and the manufacturer said to check a code on it by running a script line (cr infpfail). Does anyone know what this means and how to do it on a Mac?

    No idea. It might help though if you tell us which iMac you have and which GPU it has in it. Are you trying to mirror the display or run it in extended desktop mode? Describe acting up?

  • The screen resolution on my imac changes when I use mirror in system preferences monitor

    When I turn on my projector before lion it would just project everything from my screen at it's resolution without having to make any settings. But now with lion I have purchased a VGA to mini cable to first connect, but when I turn on the projector I see the desktop image only so it is working but nothing el;se shows.To make it work I have to go into system preference folder and into monitor and click on mirror. What happens now is the screen resolution changes both on the imac and transfered through the projector. Going back into systems preference and try to change the screen resolution nothing changes. I have heard that I may have to download firmware for the cable????, or is there a patch for lion?????. Go back to the old imac with snow leapord and it work fine????. Please can somebody help.

    Same answer as in your other thread. You need to update yosemite to 10.10.1. This was a known issue in 10.10.0.

  • Will the Apple Thunderbolt to FireWire Adaptor allow me to connect to my ProFire 610?

    Was using this for recording live instruments & vocals on a G5, but there's no Firewire port on the current iMacs.

    When you plug the projector into the computer, with the projector on, dose the computer reconize a second a 2nd display is connected?
    ie: Menu bar, click on the Apple menu, chose System Preferences, click on displays, do you see an arragment tab?
    if you do see an arragment tab, try clicking gather display windows. a window should pop up for the projector. What resolution is it set to? is there a lower resolution you could set?

  • Speakers for auditorium sound?

    I'm doing a series of iPhoto slide show presentations using a projector. Do I need to get a good set of external speakers? The projector is an InFocus X3, and I think it has some sort of built-in sound, but I was just wondering if anyone knew the best way to go, or even IF a pair of external speakers plugged into the headphone jack would be good enough sound for auditorium use (about 400 people in a room with rather bad acoustics).
    Anybody had any experience blasting music through an iMac (with external speakers) to a big party or something? What's a good set to get?
    Thanks for your help,

    cool... more details on the room.
    Presuming you ARE working from a stage AND there are mic jacks on the stage:
    Audio:
    I did this recently for a Macintosh User Group meeting... Using a small 4-8 channel mixer (if one is available - if not, keep reading), connect the iMac to the the small mixer previously described. Connect the "Main Out" via XLR cable to the mic jack on stage. iMac audio level at 1/2... small mixer audio level at about 1/3 and gain (if it has a separate knob) at about 1/2... and let the main board operator take care of everything else. Since you are feeding into only one mic jack on the stage, this set up is mono only. Stereo capabilities will also depend on the main board and amp set up, so I won't go there). If you need to adjust sound and the main board is not accessible, up the level and gain on the small mixer first - if you need more, LAST recourse is to increase the iMac's audio level - when is starts to sound scratchy, back off until that goes away.
    Guitar Center has several small mixes <http://guitarcenter.com/products/dispDeals.cfm?sel=7>... Behringer is another one they carry in their sotres - but not advertised on the web site. They are all around $150 to $300. If you'll never use it again, it may not be worth it, but the site manager might be interested. I generally use them for a drum-set (which can use 5 mics or more - if synth drums are used, too) - or this sort of "can't get to the board, so this 'pre-board' will have to make due". At the Mac User Group meetings, the main sound board is locked up in a back room, but always-on so the school principal needs only plug in a mic and start talking.
    If a small mixer is not available, then feeding the left and right audio from your computer into a single on-stage mic input jack is the way to go. In the previous post, one of the shopping items was a 1/8" male head-phone to left-audio/right-audio "tail". Instead of that, get a 1/8" male stereo headphone to mono RCA female. This connects from the iMac headphone jack to the male RCA audio cable on one end. The other end connects to a female RCA-1/4 in male... which connects to a 1/4" female-XLR male... which plugs into the stage female XLR mic input.
    If there are no mic jacks on the stage and the site manager is using a snake, then just treat the XLR connectors on the stage-end of the snake like you would if you were plugging into the board itself. The site manager should be able to assist with this.
    Video:
    Presuming you already have the Apple video converter tail for your iMac, you can get a VGA video cable as long as you want... Fry's Electronics (Outpost.com online) has LONG ones... http://shop3.outpost.com/product/4473316?site=sr:SEARCH:MAINRSLTPG There are likely other sources, but Fry's is nearby for me. If this link does not work, got to Outpost.com and search for "vga cable".
    Measuring the spot from where you will be speaking - presuming the same place the iMac is - to where the projector will be and add at least 10 feet... remember, the cable on the floor needs to get up to the iMac (on a podium) and up to the projector (on a table?). We live in a 3-dimensional world...
    Other logistics...
    Don't forget duct-tape... the cables need to be taped down to the floor so people don't trip. The site manager might take care of this, but one can always use duct tape elsewhere, so just be sure to bring a big roll. Heck, leave it with the site manager if that person does take care of it... I guess that's up to you.
    If at all possbile, make arrangements with the site manager and set up everything to be sure it all works - and you are comfortable with the sound-levels, video cable and all the other hook-ups. Presuming no one else is around, doing a short test with your computer and everything plugged in a couple of days before the FIRST time will ensure you have the right cables, adapters, and even sound levels... so that you have time to recover and get stuff just in case... AND be sure to mark all your cables and adapters and gear so everyone knows who owns what. White tape with your name (use a Sharpie) is easiest (though removeable - so pros and cons to that).
    ... and if you are speaking - hence, mic'd up - a handheld mic (better yet, a wireless lavalier) should be used so you don't have to scream at your audience - and you want to be comfortable with that, too. If handheld, is there a mic stand? Is it connected to the podium? Will that get in the way of the iMac monitor? A stick or boom mic stand (not part of the podium) might be in order - the site manager should be able to address this since you indicated there are mics... If you use a small table next to the podium for thee iMac, a lavalier (clip-on mic) would be easiest since it will leave both your hands free to use the computer while you are speaking. If a lav is not available, a couple of mics (one at the podium and one at the iMac on the table) might be in order. A wireless hand-held mic will also be useful if available (hold mic in one hand while using mouse with other) which would make the multiple wired mics unnecessary.
    By the way, what's the show about?
    HAVE FUN!
