Display dark with projector

I've been using a projector to watch TV and movies from my MacBook for over 6 months with no problems. Yesterday, I tried watching a show like I always do, and when I dragged the screen to the projector it got really dark. The display on my screen is normal. I know it isn't the projector bulb, because when my boyfriend hooks up his PC is displays just fine. Any ideas as to what is happening? Is there a way to change the display settings on my MacBook to resolve this? Thanks!

Yes, in Displays Preferences you can run a color calibration. One of the calibration steps is for changing gamma. Try a lower gamma, like 1.8 instead of 2.2.

No display arrangement with projector?

I'm trying to use 'presenter tools' in powerpoint with my ibook and don't seem to have an 'arrangement' tab in the display system preferences. The display is mirrored (the audience sees the same thing as my laptop screen). How can I change this?

tockleslie, Welcome to the discussion area!

You can't. The iBook only mirrors to an external display it does not have the ability to extend the display over another monitor.

B560 connection with projector using long cable no display

Hello Guys ,
I am having a problem with projector connection shown in the picture below.I have tried other PCs there is no problem. This case only happening with B560. Until now I did bios update. Do you think that there is problem with intel HD graphics driver ? Any suggestion ?

hi OKR-MAN,
Thank you for your post, Its really uncertain at this point to understand what exactly is causing. But base on diagram and if i were to decide from first look i'd say you have a cable failure. But may i know what type of cable are you using specifically and are you connecting through VGA, HDMI or using any converters.
Do let me know and let me check this out for you.

I connect my macbook pro to an Epson wireless projector. The macbook can see the projector wirelessly and the image on the macbook is displayed on the projector. However on system ref., the arrangement tab does not show and thus cannot have multiple view.
I am trying to project Pro Presenter on the Epson projector such that I have the detail screen on the macbook and only the screen I want people to see on the projector display. This has not been possible because the arrangement tab on the Display section of the System Preference is not showing. If i tried to search for the arangement, it comes back with the message that there is not other source detected, hence the arrangement tab is not showing.
I have also tried to connect the Epson directly to the Macbook but it still the same result, so its not because it is a wireless connection. Can someone advise me jhow to go around this problem. I have used windows before and it is very easy to extend ptojection on windows, but this system seems to be frustrating to me.
Thanks,

Cannot display through a projector

we have 2 macbook pros. My old one connects to external displays and projectors without any problem. My wife's new one however will connect to displays but not projectors. Obviously as I can get my laptop to do it I guess I know what I'm doing ..... so is there a fault on the new one or is there a trick I am missing?

Lukewarm13 I think you should start your own post with that question! personally I think you have a faulty unit.
Did some more testing. My wifes laptop will connect to the projector when using a different (short) vga lead and works fine. Then I can switch to the long cable and it still works fine! BUT if I restart the computer it again fails to work with the long cable until I have used the short lead first. weird!!!!
My laptop works fine first time with either cable!

Has photoshop started using EXIF orientation to display photos with the right rotation?

Has photoshop updated recently and started using EXIF orientation to display photographs with the right rotation?
I thought in the past it ignored the EXIF orientation, but it seems like it is now using it. Does anyone know if you can tell it not to use this information when displaying the image on the screen?
Please help!!

Duh! My apologize for not providing the important details.
The system model I have tested on:
Mac Pro Early 2009
2.66Ghz 10GB Memory
Dual NVIDIA GeForce GT 120 512MB Cards (original cards)
Tested on 10.7.4-10.7.5, 10.8.2
Crash Report can be located here:
http://pastebin.com/aeZ2kYvw (this was using version 10.7.4)
It's just odd since last year we've been using this setup fine with v13.0 and now with v.13.0.3 it doesn't work. The reason for our two independent video cards is so that one card sends video to the monitor screen of the teacher, the second card sends a video signal that can be switched to either a projector or 8 lcd monitors in the lab (we've invested a lot of video infrastructure for this lab). When we tested using a single card for both outputs we would get an odd interlace horizontal thin bar that would go top to bottom ever so slowly. This would appear either when looking at video or when moving windows around. Doing the dual video cards solved that issue for us and have been using the setup since 2009.

MBA bootcamp intel hd 3000 not working with projectors

If I use the mini display to DVI to connect to a projector, it will work if the displays are mirrored, but if I extend the display, where the projector has a higher resolution, the projector display will have artifacts, noise, and if it has a lot of pictures or videos on the screen, the display sometimes stops working. Even if i set the display resolution to match the same as the laptop, I still get noise and artifacts unless I mirror the displays. Any ideas?
Then if I true to use the mini port VGA to the same projector but Windows won't recognize the projector. I've seen several reports about this. I have the latest Intel graphics driver and my bootcamp partition is running Windows 7, fully updated and patched. I've read some people are suggesting buying a 3rd party mini port to VGA connector to solve this problem. But can anyone confirm?
Lastly, this seems to only happen with my MBA with the Intel HD 3000 graphics. I have another MBA with the Nvidia 300M and the mini port to DVI works fine.

Hi all,
I have same problem with my MBA 13", can't project to projector & some LCD TV via using Mini VGA port in Windows 7. Any solution and pls help.

SharedObject with Projector

Hi,
please, is it possible to use SharedObject with Projector? I
mean, if someone doesn't have Flash installed and gets the CD with
the Flash app burned in, is it possible for the app to store data
locally?
I'm asking because from what I understood SharedObject is
always stored in a very specific location, but what happens if
someone doesn't have Flash, i.e. the location shouldn't exist?
Thanks in advance!

You are extending your desktop onto the projector, instead of mirroring your internal display.
With the projector hooked up (your blank desktop showing on the projector indicates you are properly connected) go to System Preferences > Displays > Arrangement tab and check the box to Mirror Displays.
Hope this helps...

How to use old 2005 cinema display (20'') with MacBook Air (mid-2009)

My old 20'' cinema display (2005) has three ports coming out of its power box (single-port dvi, usb, firewire). Is it possible to use this display with my newer MacBook Air (mid-2009) ? If so, what kind of connector do I need? Thank you very much for your help.

To use my old Cinema display (2005) with my old PowerMac G5 (2005) I had to plug in all three ports (DVI, usb and firewire) into the desktop. Can I really use the display just with the DVI output plugged into my MacBook Air mini-Display Port ?

Display Issues with mini (Mid 2010) and LG L246WP

I recently purchased a new mini (Mid 2010 base model) and planned to use it with my 24" LG L246WP monitor, which is about 3 years old. The monitor has VGA, component, and HDMI inputs.
I used an HDMI-to-HDMI cable to connect the mini directly to the monitor, and the output is completely messed up. The mini recognized the monitor (titling the System Preferences > Display dialog with 'L246WP') and set it to the monitor's native resolution of 1920x1200, but on the monitor the image is cropped to what looks like a 4:3 aspect ratio and with part of the image shifted up and left so I cannot view the top menu bar or the left hand side of the desktop. The monitor's on-screen display shows 1080p in this mode.
The Display dialog also gives me an option for 1080p. I can select this and use the Underscan slider to resize the desktop output to fit on the screen, but it is still shifted left and must be resized smaller than the available display space (plus the total image is only 1080 pixels, not using the monitor's full native screen). In this mode, 1080p also shows on the monitor's on-screen display.
I tried 1024x768 to see if I could get a properly-positioned image, but the desktop was shifted just like in the 1920x1200 case and the monitor's on-screen display status still reported 1080p.
The monitor has a menu setting under an HDMI heading with "Video" and "PC" options, but changing this selection does not make a difference.
Since the monitor came out before HDMI was as widespread as it is today, it came with a DVI-to-HDMI cable, so I also tried using that cable with the HDMI-to-DVI adapter that came with the mini, but this did not make a difference either.
To prove it wasn't the HDMI cable, I connected the mini to my Samsung 6300 series 40" LED HDTV and with some tweaking of the Underscan slider the displayed image filled the screen perfectly.
I've searched the Internet and various forum threads (i.e. http://hardforum.com/showthread.php?t=1167222&page=63) seem to indicate this monitor can send a corrupted EDID that causes issues, especially with nVidia graphics drivers. On Windows you can use registry or driver hacks to override the EDID with the correct values, but on OS X this doesn't seem possible (I was hoping for a Terminal one-liner but it seems this doesn't exist). I have seen some mentions of the shareware SwitchResX (http://www.madrau.com), which looks like it gives you the option to override resolution settings, but I haven't tried this yet.
It also appears to me that the monitor is always interpreting the signal (or the mini is always sending the signal) as 1080p, even if I've set 1920x1200 in the Display dialog. I don't know if this is a defect in the monitor where it always assumes the HDMI input is a 1080p source (previous I used it with an Xbox 360 with no issues but that was 1080p HDMI), or if is a bug in the graphics drivers (or at least a lack of flexibility / miscommunication to the user trying to handle a corrupt EDID).
I asked my local Genius Bar for advice today (without bringing any hardware in) but was not told anything I didn't already know.
I'm trying to determine the best way to work through this issue. *My questions are:*
Would it make any difference if I used a Mini DisplayPort-to-DVI adapter (and then my DVI-to-HDMI cable to the monitor's HDMI input)?
What about a Mini DisplayPort-to-VGA adapter? In the past I used a 12" Powerbook (via a mini-DVI-to-VGA adapter) with this monitor and had no display issues like this, but I'd prefer to stick with a digital connection on my brand new mini.
Is SwitchResX the only practical way in OS X to override a corrupt EDID and force the mini to output a certain resolution?
Besides the various adapters and SwitchResX, is there anything else I should try before buying a new monitor?

Hello EPWilson4984.
I have been experiencing the same issues you described. Connecting my brand new Mac Mini to my Westinghouse 24”monitor (L2410NM, 1920x1200 pixel resolution) produces a very fuzzy and washed out image quality. The Mac recognizes the monitor and applies the right resolution (1920x1200), but it looks just awful. The EDID info is definitely not right.
Now, I tried your suggestion (DVI-to-HDMI), and similar suggestions from other threads, but nothing works. Nothing seems to work at all.
The main input for the monitor is HDMI, so whatever cable I use, in the end always has to connect to the monitor via HDMI. I tried all these combinations with zero success:
Mac mini -> HDMI cable -> monitor (result: fuzzy and blurry image)
Mac mini -> displayport –HDMI adapter-> HDMI cable -> monitor (result: fuzzy and blurry image)
Mac mini -> displayport –DVI adapter-> DVI-to-HDMI cable -> monitor (result: it gives me a blank screen, no image at all)
I’m running out of options. Don’t know what to do. The 24” monitor produces beautiful, crisp images when hooked to my Windows 7 PC. It looks horrible when connected to my brand new Mac Mini.
Any alternatives you may have come across? Please let me know, thank you.

Studio Display 21" with Mac Mini?

I am considering getting a Mac Mini as an economical upgrade to my B/W G3 system but I want to make sire that my monitor is going to work with it. I have the origingal blue and white 21" Studio Display. the System Profiler says this......
Displays:

Will this display work with a new Mac Mini? I really do not have the $ right now to get a new Monitor and this one works great anyway. I am also wondering how my current software,,,,,,, Photoshop,Indesign etc. will work with the new Intel Macs?
THanks for any input

Can't help on the screen much - believe you need to get an adapter, as the previous post indicated. You might check in the Apple dislay area at http://discussions.apple.com/category.jspa?categoryID=111
Regarding your applications, as long as you're not running under OS 9 or earlier, your applications will run on the Intel mini under Rosetta emulation. Universal applications are those that have been modified to run on both the PPC and Intel macs, and they run natively. Those applications that have not been made universal run under Rosetta emulation. Photoshop is an example of an application that has not been made universal yet (supposed to happen this year with Photoshop CS3). Running under emulation does extract a performance penalty, of up to 50%, versus running in native universal mode.
If you have applications running under OS9 or in the OS X classic environment, you'll need to upgrade to an OS X version in order to run on the Intel-based mini, and you may find there are Universal versions of your software, which would be even better.

Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro

Cinema Display (clear) with DVI/ADC box doesn't work with MacBook Pro when plugged in with a dvi to mini dvi cable. Any ideas what to do to make it work? I lugged the 23" 2500 miles into the wilderness and I need help

Okay, here's an update: the DVI to ADC adapter does work with the Apple displays that I have tried, but it won't work with the Formac. I have tried multiple time to contact them, but to no avail... they don't even respond to threats of posting my opinion of them, which is this:
DON'T BUY ANYTHING FROM FORMAC! They make quality products, but their customer service is a big time joke! They won't take care of you.
