Problem connecting to projectors

With all versions of Mac OS X that I can remember, it has been a breeze to connect to projectors. Everytime I connected to one, I got a decent image right away. Sometimes I was able to get a higher resolution after that first successful connection, but even the first setting was acceptable.
Since upgrading to Snow Leopard, results are much more erratic. I connected without problem at a recent conference, but most projectors at my workplace give me difficulties even though I connected to the same projectors without a hiccup before Snow Leopard. Usually the projector says "no signal" and it does not matter if I connect before or after turning the projector on (something I never even worried about before).
Today I had to use one of our projectors and the only way I could get it to work was to select mirroring (goodbye the nice Keynote's presenter's screen) with a resolution of 1024x768 at 60 or 70 Hz. Disabling mirroring or changing resolutions or chosing higher frequencies resulted in a "Signal not compatible" message. This is really annoying. I don't remember having done anything with my settings that could cause this.
Anyone else encountered this or has a solution to offer?
Thanks in advance,
Denis

Using Keynote run, Snow Leopard puts slideshow and presenter screen on wrong monitors, so i get the presenter on the projector/external monitor. Works like a dream on Leopard with same file, never had a problem with Keynote before. Cannot find a way to set the screens right, application crashes if I move the edit window to presentation and try to run from there. This must be a bug that needs to be fixed - urgent- I have a presentation to do on April 12, bought a Macbook pro to avoid having to carry along my old Imac24 which never ever caused me a problem.

Problems with recognizing projector.

Hi all, I'm a spanish teacher at my local highschool and I have a projector that is availible to the students to use for powerpoint presentations and the such, but recently I upgraded from my older mac laptop, to a new mac-pro powerbook. the projector no longer recognizes the computer and vice versa, anyone have any similar experiences/fixes/help that they could offer me?
if so that would be wonderful.
thanks in advance,
Terri Salsman de Rodriegex

there is definitely a problem connecting to projectors. I have a 50% success rate when going into meetings with a foreign projector. Compared to my Powerbook which was much higher (100%). Not sure what the issue is... and yes, i've tried F7 (mirror) and changing the resolution, and other "sys pref" settings. even tried rebooting (if this had worked i would still say that it's broken, shouldn't have to reboot my machine to connect to a projector).
at this point it doesn't work most of the time, not sure where the prob is (video card, adapter, etc.) but there is def a problem.

Problem connecting MacBook to a Sharp video projector

One of the great things I like about Macs is the easy way they (usually) connect to a video projector. Unlike a lot of my friends who run PCs with Windows I never had any problems whatsoever connecting my MacBook to a projector at the university and start my presentations.
Until today that is.
I tried to connect my MacBook with Apple's mini-DVI to VGA adapter to a Sharp ("Notevision") video projector and although the MacBook had the projector (even with its correct name "PG-M20X" and available resolution settings) listed under "Displays" immediately, I couldn't get the projector to show any more than "no signal" whatever input source I chose...
What did I do wrong? Or is it the projector that is somehow "incompatible"?! Please help!

Maybe this could help as well:
After we tried several things with the MacBook (reboot, "detect displays" etc.), we successfully connected a Powerbook (15", FireWire 800, late 2003) to the projector, using Apple's DVI-VGA Adapter.
So that did work out fine, but the MacBook didn't work on the projector. The cable that came with the projector was a VGA--DVI-A cable: there were only a few pins on the DVI-end of it going into the DVI-Connector on the projector. Could it have something to do with that? But why didn't the Powerbook have any problems connecting to the projector then?

Problem connecting an external display or projector to Retina Macbook Pro

I have a problem with my rMBP (MAC OS:10.8.2) and i'm not sure if it is just an easy fix or if there is a serious hardware issue.
I connect my rMBP to an external projector Hitachi CPX3011 (max resolution 1600x1200) very often for my presentation.
I use a Thunderbolt port to mini display port to VGA adapter to connect my laptop to this projector.
When I plug it into my projector the screen on my rMBP goes black and nothing shows up on the projector.
I try both of the Thunderbolt port, the rMBP switches resolutions and goes back
I called Apple, but the guy just told me to they never encounter this before, (case number 368401545).
Is there something that I am missing here???
Or do you guys think that my Thunderbolt port could be faulty.
By the way, just to be a little more descriptive. When I connect my projector to my rMBP on the port that doesn't work, my screen immediately turns black. I can still see my mouse pointer, but its incredibly HUGE. About the size of a dime.
Please help if you can. I really appreciate it. Check out the video for this problem.

I had the similar problem but it was specific to running windows 7 through bootcamp. The only way i was able to get the laptop to work with a projector was by purchasing a USB 3 to Vga dongle (essentially an external graphics card)

Problems connecting projectors

I have issues connecting external projectors to the Kirabook. I use a HDMI to VGA adapter and all circular objects look compressed in the x direction. The same slides on another widescreen notebook connected to the same projectors look just fine. Changing the resolution of the presentation in Powerpoint does not make any difference. Any advise is appreciated. This issue has happened for my last three presentations on different projectors.

Please contact KIRA Platinum Service & Support. They should be able to help you.

Having problems connecting a late 2011 Macbook Pro 2.2ghz i7 to a Sony KDL-32L5000 using a display miniport to DVI adapter (DVI to VGA cord). The TV is not detecting the macbook. Anyone have this problem?

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.

Connecting to Projectors

I'm having problems connecting the iBook G4 to a projector at school, on my old iBook it connected with ease but this one doesn't seem to work, i've tried clicking on detect displays and gather windows and nothing happens, my computer recognizes the projector but the projector doesn't recognize the computer. I think the model is an Epson Pj -28E84481.
Please help!

Danke!! I've looked it up on Google images and will try to purchase one with the picture printed out to show a salesperson.

Cannot play the video in powerpoint when connected to projector

i have linked a video into a powerpoint slide... it played perfectly on the screen. but when connected to projector it cannot be played.
i am using a macbook pro with Lion OS.
Thanks!

I had the same problem today in front of an audience with 300 people (MacbookPro OSX 10.10, Thunderbolt-VGA adapter, PPT 14.4.6).
Here what I figured out so far:
1. It happens when you have PPT open and connect to beamer afterwards
2. You can resolve it (in my case) by quitting PPT and launching it WHEN connected to beamer
3. Yet, make sure Mac does not go into sleep mode or you get a lock-screen in the waiting time. if you do so, you get back to square 1. quit PPT again 2. restart it.
4. Also.... in one case I had to hit the volume control once to get the sound back even though movie was playing
So in short: Connect to beamer first, then launch PPT
I know it is only a symptom fix but it worked for me

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.

ThinkPad W530 with Windows 8 x64 Pro BSOD when connecting to projector

Nine, that only covers Widows 7. Many people in this thread have reported the problem using Windows 8. Has that been addressed by Lenovo yet? Stability problems like this should NEVER be allowed to go so long without a resolution.
Edit Note : This thread was created base from the previous thread "ThinkPad W530 with Windows 7 x64 Pro BSOD when connecting to projector. As we currently Cx reporting facing the same issue on Win8 I have seperated this thread in order not toconfuse other customer. For cutomers facing this issue please continue posting in this thread.

Hi shan_mcarthur,
Thanks for posting. I read through this thread again and noticed that most of customers here do indeed have Windows 7 installed as what the title represented unless I'm mistaken or may have missed out are you or anyone else here facing the same issue on Windows 8. If that is the case I'll be more than happy to bring this up with the teams but it will have to be a new thread though as I'd like to keep the resolution separate based on the OS use just to not confuse other customer .
For those facing the same issue above on Win8, please do let me know so we can start a discussion around this.
Do let me know.
Regards

Thre are many issues discussed about trackpad problem. My problem comes in the trackpad when X220 is connected to Ethernet port. The curser is not stable and it jumps aout 1/2 cm right and left withlout any figer movement, It vibrates on its own when only finger is placed on the touchpad. This does not happen when Ethernet port is diconnected even with 90w adapter or 65w adapter plugged in. It comes with Ethernet only.

This is very frustrating, has happened both times when I tried to connect to projector and reboots after which connects to projector without BSOD.

Yes I am having this problem as well.
When connecting my W530 to a projector using the VGA-out port, I get a bluescreen regardless of whether or not I am plugged in or not.
HDMI-out works fine. I have yet to try to find an adapter for HDMI to VGA.
Using Windows 8 and NVidia 320.00 WHQL Quadro drivers.
The relevant difference between his and my W530 is that I use a K2000M.

Problem with multimedia projector

We have intermittent problems connecting with a Sanyo multimedia projector. I have tried switching mini-vga converter and it does not solve the problem. Does anyone know if this is a known compatability issue with ibooks and multimedia projection?

If the issues are related to 'supported' iBook resolutions verses those
the projector is supposed to run on, one of the means toward making
them work has included using a software utility named [ SwitchRes X ].
There may be some other issue behind problems you encounter in the
use of a projector and an iBook or other portable. Some projectors may
support a different video signal than the iBook can use. (I don't know.)

I'm trying to set up my Ipod, but when I go to sign in with an apple ID it says 'Could not sign in: there was a problem connecting to the server'.

I just bought a 3rd generation ipod touch. It was professionally refurbished. I'm trying to set it up, and everything seems to be working fine, until we get to the wifi. I live on campus and our wifi is username and password protected. I signed in and everything seemed to work fine, and in the top left hand corner I have all the bars for wifi. However, when I go to sign in with an apple ID it says 'Could no sign in: there was a problem connecting to the server'. I've tried turning it on and off again, tried signing on to our wifi again, but it all isn't working. What can I do?

I also encountered the same problem. Try using a different email address or try signing in later.

I am having problems connecting to home wifi. It was working, but now all I get is a blank white screen. I re-booted with no success.
