Ti book detecting displays/projector

I want to project a Power Point display from my Ti book(a 550 upgraded to 1.2). I was told by the projector owner that I needed to plug the computer in to the projector before I turned it on which is fine, but the Mac detects no displays until they are connected, so it appears that the projector detects no source(it hunts for imput. I have tried 9 pin and s video connectors w/ no results. Help.

Hi, mwizard. I routinely connect my Tibook to my projector with the PB asleep (it's almost never turned off) and the projector off. Then I turn on the projector, let it warm up, and wake the PB. On waking, the PB detects the projector and, if it's in mirrored mode (as I usually use it), self-adjusts its built-in display resolution (normally 1280 x 854) to match that of the projector (1024 x 768). On the rare occasions when the projector displays only a blue screen and "no signal", going to the Displays preference pane and choosing "detect displays" corrects the problem.
Hitting the F7 key toggles between mirrored and extended-desktop modes.
After using and turning off the projector, I put the PB to sleep, disconnect the projector from it, and wake the PB. It resets its built-in display resolution to whatever it was before the projector was connected, and I go on about my business.
Give this procedure a try, and if it doesn't work out for you, post back to report exactly where it's gone wrong.
I doubt that the processor upgrade in your Tibook has anything to do with a video problem, but I guess the possibility shouldn't be dismissed out of hand.
Post back with further news.

My MacBook Air (OS 10.8.4) does not connect to projectors consistently using a VGA/Thunderbolt connetor. The Monitors/detect displays box that I am used to never appears. Intermittently the "arrangement" window appears in the Displays System Preferences

My previous MacBook Air running an older operating system synced up just fine with these same projectors using the same minidisplay to vga adapter. My new computer has Airplay on it, and Airplay shows up on my menu bar on the new laptop where the displays icon used to appear. I cannot get the displays icon to display (even when I turn Airplay mirroring off). It used to show up on the menu bar and if I had projector issues I hit "detect displays" and it resolved. None of that appears to be available with the new operating system and Airplay on. I am not sure why.

I'm having trouble using multiple displays on Mac Pro 2006 (OS X 10.6.8). System Preferences does not detect my projector. Suggestions?

When I enter System Preferences and select Displays, I am given a button to direct OS X to Detect Displays. But when I choose the button, nothing seems to happen. There are only two tabs visible--Display and Color--neither of which has anything to do with getting the software to recognize that a second cable has been

PB G4 detects VGA projector but not 20" ACD

I'm having a strange problem when connecting my 15" PowerBook G4 Ti DVI to a new 20" ACD. When I first got the display, I was able to connect just fine for about 8 weeks. I went on a trip and since my return, the PB won't detect the display.
I took the PB to a Mac store and tried connecting to another 20" ACD... no luck. This lead me to believe that the display adapter was shot. However, I just tried to connect a Benq digital projector via VGA and the PB detects the projector without issue and works in both dual display and mirroring modes.
So far I have reset the PRAM, the NVRAM, and the PMU, but it didn't help.
I've also repaired permissions and repaired the disk (no errors found). Again, no luck.
Finally, I tried closing the lid on the PB and clicking the external mouse to see if I could force the PB to display to the external 20" ACD. The technique worked for the Benq projector, but failed for the ACD.
At this point, I'm not even sure how else to troubleshoot this issue, let alone fix it.
Anyone have any ideas what might be causing this? Could it be a corrupted driver? Is there any way to reload the display drivers without having to do a fresh OS install?
Your help is greatly appreciated!
15" PowerBook G4 Ti DVI Mac OS X (10.4.8)

I've got a similar problem, my 15" aluminium powwerbook 1.5ghz will not display an image on the external 20" alu cinema display when connecting using DVI.
Have reset pra, checked cables power, screen just stays blank!! The 20" display works fine in exactly the same situation when using my wifes 17" Macbook Pro
The powerbook feels the external monitor [laptop screen flashes when connecting cable] but will not detect it as a valid external monitor. Use all the time at work with an external 21" CRT and VGA adaptor.
I've searched these forums and seen a couple of people with same problem but no answer as yet.
Very frustrating!!!

My MBP won't detect a projector even when I reboot the system.

I can connect to a monitor, so I know the adapter and cable are working, and my old HP will connect to the projector so I know it's not the projector, but my MBP will not even detect that a projector is connected.. I have tried multiple projectors as well. I am using a VGA cable with the apple adapter. I have read old threads, but there doesn't seem to be anything recent, and it seems like people were able to find the projector after restarting the system. I have tried all of the various displays sizes and colors; I have tried connecting the cables in various orders as one person said this worked for them, I have tried turning off the computer first, then connecting everything, I have tried connecting everything then restarting, but my computer just won't detect the projector(s). Any thoughts?

You can ignore those instructions. Adobe has what I believe is an easier way to install Flash by using the manual installers. See the Adobe troubleshooting guide - http://kb2.adobe.com/cps/191/tn_19166.html#main_ManualInstaller

My macbook wont detect my projector. what can i do?

my macbook wont detect my projector in detect screen display. what can i do?
i have changed and bought new cables but no change. the computer seems to be the issue...
thanks joe

Are you using the Apple VGA adapter or one from another company? Often the third-party adapters do not work well/reliably and the Apple one must be used.

Detect Display button gone!

This is a rather infuriating mess-up in Mountain Lion. My wife is an educator and has a class room projector she has to connect and disconnect to on a daily basis with her brand new Macbook Air.
The problem is that her Macbook Air will not detect the projector when she connects it.
The only way it will detect is if she either restarts the computer with the projector already connected or puts her computer to sleep and waits for to wake up and that sometimes works.
Where as in Lion or any other previous version of OSX in the past five years you had the option of a Display Menu button (also gone) up at the top of your screen that showed connected displays as well as a Detect Diplays option that would do the trick. To make things worse even if you go digging to the System preferences under Displays Preferences they completely removed the Detect Displays button!
The funny part is the Apple help menu still tells you click the Detect Displays button that doesn't exist.
How on earth do you take such a monumental step backwards with an OS upgrade by making settings more difficult than easier? Having to restart a computer to detect a display? As a Mac user I haven't had to do that in the past 10 years! Please return us all the display options that should be available under any circumstance period.

Well folks I did find a work around for the time being. Though it doesn't restore my options in the menu button I did uncover the Detect Displays button. I was looking at my post request and behold I saw a related article next to this thread that says OS X Mountain Lion: About the Display pane of System Preferences ( http://support.apple.com/kb/HT5369?viewlocale=en_US&locale=en_US ) in the article it shows that they did indeed hide the option but it can be uncovered. The funny thing is this article does not show up when I search for my problem.
Hold the OPTION key in the Display Preference pane and the Gather Windows button will transform into the Detect Displays button.
Here are screenshots to demonstrate what happens when you toggle the OPTION key off and on.
Again why on earth did they hide this to begin with or not include it in the Display Menu option at the top of the screen? I don't know and I hope they fix it. This is WAY TOO complicated of a solution for a simple function. Nobody is going to intuitively find the Detect Displays option.

MBP (2011) can't detect LCD Projector, says NO SIGNAL

with appropriate Mind Display Port to VGA Adapter, my MBP (mid2011) doesn't detect LCD Projector. I tried Safeboot start up, and also resetting PRAM (Command+Option+P+R).. But both strategies did not work. What else should i do? Thanks!

Auto-detect displays not working in mountain lion

I keep a VGA projector connected to my laptop and Mountain Lion seems to believe that it is on all the time. Thus, I'm stuck with windows off screen. Anyone discover any fixes? No menu bar monitor ajustment preferences appear, nor does detect displays work through system preferences. I have a late 2008 macbook pro 17" with a DVI to VGA adaptor. Thanks

In System Preferences > Displays > Gather Windows.
You could also switch to mirror mode by Pressing CMD F1 to reclaim or end tasks then press it again to return to extended desktop mode.

Mac Book and LCD Projector

Hi,
When ever I connect my Mac Book to LCD projector, the display resolution on Mac Book automatically changed to a lower resolution, which resulting in a not so nice (blur) display both on Mac Book and Screen. I have tried on few LCD projectors older and new, but all of them gave me the same problem.
Any idea or suggestion are appreciated.
Thank you

you can change the resolution back.. (in displays preferences)
the desktop always looks blurry for some reason i get that on my plasma and the girlfriends lcd..
i dont know why but when i play movies they are clear?? but for general using the comp i find it blurry as well.
i would love to have a crisp pic after all the tvs are high deff..

Help! G4 PowerBook "Detect Displays" triggers shut down message

I think I may have damaged my PowerBook by being too lax with a DVI/VGA adaptor when unplugging it from a VGA multimedia projector - I was in a hurry and removed it from the Mac whilst it was halfway through shutting down. (I've gotten away with this before but have since heard it's not a good thing to do, probably even worse if halfway through shut down).
If I choose Detect Displays now, it triggers the "Are you sure you want to shut the computer down?" message.
I also am unable to boot up successfully unless I hold the Option key during the initial black "chime" screen - the PowerBook appears to die with a squeak - both the HDD and SuperDrive lose power. Option-V won't give me a verbose boot unless I flash the PRAM, and then works only once.
(I've reinstalled Tiger 10.8.4, have run Disk Utility and have flashed the PRAM.)
Has anyone else experienced a similar problem?

First off, I think you got your numbers confused. There is no 10.8.4. There is 10.4.8. But that's immaterial here. You should try to run the hardware test than came with your Powerbook:
http://docs.info.apple.com/article.html?artnum=86287
It may be you shorted the signal to the videochip, or the power supply.
Resetting the power manager may also work

Be sure when booting off the disk, to disconnect all thrid party peripherals.

Cannot detect display

Hello,
I am trying to sinc a Dell projector with my macbook pro. I am using a VGA adapter, and my computer seems unable to detect the display. I've tried refreshing the display and putting my computer to sleep. Everything is plugged in tightly. Can anyone help?
Thanks!
Sarah

Try connecting it all, remove all other peripherals, boot the MBP, then turn on the monitor, if still no joy, go to system preferences>displays click detect displays. Also you should put your OSX in your profile, as this might get more people to answer your post, the monitor issues are different with the OS. All the best.
Sorry also make sure mirror display is clicked.

Detect displays seems to have quit working? The secondary monitor is bleeding into the MacBook Pro monitor. How can I fix this?

I am using a MacBook Pro 2009, Snow Leopard (OSX 10.6.8). All of a sudden last night after a long day of work, my monitor resolution changed without warning and the secondary monitor display started bleeding into my laptop monitor. When I go to detect displays, it doesn't fix the problem. It looks like I need to switch to a larger display setting and the largest setting has disappeared.(The display seems to default to this setting where my screen bleeds into the laptop monitor.) When this started happening last night, I immediately shutdown and restarted to see if this would fix the problem. So far, it's still not looking too good.
I also tried shutting the laptop and using the external monitor only. When I do this, the monitor freaks out and keeps flashing on long enough for me to input a password. Then it flashes off, the computer and dipslay goes to sleep and I have to re enter my password to exit sleep mode and the process starts all over again.
Here are screen shots of the two monitors side by side:
http://danisco.files.wordpress.com/2013/07/monitors.png
(Notice the weird overlap - it's not keeping me from working, but it's super annoying!)
Any ideas on how I can try and fix this? OR do I need to get help from Apple directly. Thank you in advance for any suggestions on this!

Okay - this issue seems to have resolved on it's own. Yea!
I did find a thread that suggested resetting the PRAM/NVRAM so I did this, restored the external monitor to factory settings and went into Disk Utility and repaired disk permissions and verified disk permissions.
Here is a link to reset the PRAM/NVRAM: http://support.apple.com/kb/HT1379
These things may have helped resolve this issue. I can't tell what worked because it was hours after I did all these things that my monitor and computer decided they liked each other again. If you have a similar issue, maybe these steps will help you resolve your problem too.
Hope this is helpful!

Detect Displays no longer works after upgrade

Mac Mini 2009 - two weeks old, came with Leopard. Took some doing, but have it hooked up to Sony Bravia 40" LCD via Mini-Display port to VGA adaptor. Detect Display worked fine, connected at High Def resolution. Upgraded to Snow Leopard 10.6.1 today, and Detect Displays finds nothing, I can't get any more than 1280 x 768 out of the display, no high-def. Tried many of the tricks I found in forum - zapped PRAM, booted into safe mode, deleted windowsserver preference plist files. No avail. Is this a general problem with Snow Leopard?

I do have the same problem with the macbook alum. After the upgrade, i have no more resolution of 1080i, becouse it fails. Only res like 1280*1024 is the max i can get. I figured out that the profile of my LCD bravia is no longer detected by the display manager, back in 10.5 it was "Sony Lcd" (or something) now is "Vga display". EXTREMELY WEIRD is that after a lot of test's (reset ram, delete profiles, etc, etc) i try to change my vga cables, first try... no luck, back to the classical cable and "MAGIC" 1080i res came out of nowhere, and the profile was Sony LCD... but it was just one time (i reboot and it was gonne!!!) i haven't been able to recreate the same thing. So i still stuck with this subject and low res for the mini VGA display adapter!!!
