Video output to projector

Just got my new MBP 17". I use an older Infocus LitePro220LCD projector to run visuals. On my older iMac G5 I use another adapter to run video out to projector, the projector is about 20' away, it connected via an RCA or "S" video. The MBP has a different adapter. Advise Suggestions??

The audio/optical out port will accept the tonslink miniplug for digital out only. You can also use the port for 1/8 " headphones without the miniplug. The video out is on the otherside, its the DVI port. The macbookpro comes with a DVI to VGA adapter. You should hook up your projector to the DVI or the VGA. If you projector does not have DVI or VGA you can adapt from VGA to RCA.

Satellite laptop: connecting video out to projector causes hum in (headset) audio output

Our church connects video output from the laptop to a projection system and audio out (via headset jack) to a sound board mono channel (line in). Stereo to mono adapter. We get a significant hum in the audio whenever the video cable is plugged in. Doesn't matter whether the attached projection equipment is on or off, it's all about plugging the video cable into the laptop. Unplug the video cable and the hum disappears. Obviously we have tried all sorts of things to isolate the problem but it all comes back to plugging in that video cable. We made sure there were no nearby power supplies or other equipment that might throw out interference. Has anyone ever encountered this problem and have any suggestions? Thanks in advance for any help you can offer.

Using a Satellite PSBY1U laptop. Video out is not HDMI but the other (VGA?) connector. We are connecting audio out from the headset jack direct to a mixer channel. No microphone is connected to the laptop. We looked at every sound and video-related menu we could find and could not see any settings that would seem to be relevant to the problem (we changed lots of settings anyway and nothing helped). Naturally we played with audio volumes, different auto cables, etc. Bottom line is we get clean audio until we plug the video cable into the laptop, then we get a very prominent hum from the audio output. Video cable goes straight to a projector, doesn't matter whether the projector is turned on or off. The audio and video cables are never closer than four inches from each other. It's weird.

Lost S-Video Output

I have been using a G4 Powerbook 17-inch, 1.33 Ghz connected to an NEC VT470 LCD Projector through the S-Video output (Mirroring). It had been working just fine until recently - the s-video output stopped working. The odd part of this is that if I connect through composite video and the s-video to composite adaptor,It works. I have confirmed that the s-video input of the projector works, and i've tried the same thing on a 52" DLP rear-projection TV with the same results - composite video through the composite adaptor but no s-video straight through the s-video output. This makes me wonder if there's just a setting that's been changed or turned off. Another note: the Powerbook will not "detect" the projector when connected through s-video, but it does when using composite through the adaptor. Any ideas?

That does sound like a faulty video card - I just read another post regarding faulty video card - in that case replaced under warraty by Apple.

HD video output on TiBook?

Is there any way to get my TiBook 400 MHz (15 inch) to output at HD resolutions? I just bought a new 1080p HDTV, and I can output using S-video to the TV', but then the resolution on the big screen TV looks crappy.
My TiBook also has a VGA port, and I've output to projectors to give presentations many times. . . but there is not VGA input on my HDTV. . . only composite video (ie: non-HD), S-video (same), component (HD), or HDMI.
Is there such a thing as a VGA to HDMI (or component) adapter? And, if I were to use it, would my I be able to get High-def resolutions on my HDTV from my TiBook?
Thanks.

Hi, dgalvan. No, your old Powerbook doesn't have any digital video output capability, and its 8MB of VRAM can't support 24-bit color at any resolution higher than 1280 x 960 on an external monitor or TV, regardless of how it's connected.
EDIT: However, you do have one of the only PB G4 models whose video can be upgraded with a CardBus add-on. For somewhat more than your Powerbook is worth, you can add a DVI port to it and increase its maximum output resolution to the HD level. I can't help you with any of the details or side issues (notably how to get audio to the TV) because I don't know diddly about HDTV.

Video output enabled on iBooks app?

Dear friends,
As I would need to make a presentation with an eBook file I created with iBooks Author, does anybody know if the video output is enabled on iPads while using iBooks app? That would be the only way to show ay eBook live with a video projector.
Thanks for your help!

Not all apps are enabled for airplay, this is up to the developer to do.

Video output via cable - incompatible with video p...

I find that although video output via cable from the Nokia 6220 classic (and I presume other Nokia phones) works fine with TV sets, I haven't found a single video projector that accepts the output and is able to project it. The projectors typically search their video inputs and should recognise the composite video input, but instead they just keep searching and are never able to recognise or project the video.
Is there something unusual about the video signal output from it so as not to be accepted as composite video by video projectors?

iphone4 and composite and component cable don't support mirror so they
only display images when an supported app is being used like youtube or the video app and the likes
use both the composite and the component cable with my iphone4 on 5.1 and both works fine
so do my ipod touch with 5.1 and ipad2 with 5.1

Why my Ipad2 will not play rented video to a projector via vga adapter connection

Hi, i want to know why my ipad will not play rented video to a projector using the apple vga adapter connector. This is just basic mirroring and there should be no problem isn't it? Please help.
Thank you

Technically, yes, it should be easy. However with rented videos you may be running into DRM (DIgital rights management) where you may not be allowed to play that video anywhere but on the iPad. The video could have a bit of programming in it that literally tells the HDMI or VGA output not to work.
One way to test the connection, with your ipad's camera, shoot a short video and try to mirror that. If it mirrors and the movie doesn't then it's likely that you're simply not allowed to mirror it. If it doesn't play then there may be something wrong hardware or setting wise.

Video Output for Musical on new Macbook Air

Doing first production of a musical.
I'm thinking of buying Logic Pro 9 to control the output of recorded audio and video for the show (as well as to compose a few extra pieces).
The features page on the Apple site says: Logic can let you view synchronized QuickTime movies on a separate monitor using output options like Digital Cinema Desktop.
http://www.apple.com/logicpro/top-features/
The Tech Specs page on the Apple site says: External video output via FireWire or DVCPRO HD.
http://www.apple.com/se/logicpro/specs/
I've bought a brand spanking new Macbook Air which has a Thunderbolt and two USB ports.
Would I be able to use Logic on my Macbook Air to output my video? (I was thinking I would do it to a projector either through WiFi or a (yellow) composite cable.)
(The alternative I was thinking of was to use MuseScore to enter the notation for the extra pieces. Garageband for the audio output (it's missing a few instruments [e.g. clarinet, xylophone]) and plain old Quicktime for the video output.
Thanks!
John

Ibook video output

does the video adapter for current ibooks require that the tv you are connecting to has an s-video connection? if so, is there any other kind of cable/accessory available that will give you either an av or scart connection - like the video adapter for the older ibooks does?
thanks

That is incorrect. The iBook G4 specifications indicate
VGA video output for video mirroring on an external display or projector (24-bit color) with included Apple VGA Display Adapter.
S-video and composite video output to TV or projector (requires Apple Video Adapter, sold separately)
You only need the Apple Video Adapter M9109G/A. Also see KB 88396, iBook video output cables/adapters and resolutions.

Horrible-looking video with Dell Projector

Hi guys,
Forgive me for posting anything regarding compatibility with a Dell projector - I had no choice. A customer had a room set up with a Dell DLP projector. The MBP recognized it just fine. However, the video output (using the VGA dongle) was just horrible. The video looked low brightness, and very high contrast. Subtle gradients were absolutely atrocious looking. The output when driving with a Dell Laptop looked much better.
Hooking up the VGA output to a Dell LCD monitor, and to a Sony CRT monitor looks just fabulous, however.
Do you guys have any idea why the video would look so horrible, and what I might be able to do to correct it, outside of buying my own projector?
Sincerely,
Rob

You're going to get horrible colors with 99% of all the projectors out there, especially the way most conference rooms are setup.
Things I've noticed that really help with the de-facto business standard of Dell projectors.
1) Use a white background. (yes it really, ***** to make UGLY keynote presentations). But unless the room is pitch dark, black, and especially the gradient black look horrible.
2) Always design for 1024x768, 99% of all the projectors are still stuck at this resolution.
3) Keep stuff away from the edges of the screen, the Dell's destort the edges pretty bad, and often the setup in the conference room makes the image crooked on the wall/screen

Lowlevel video output switch controls? Modulized, why?

Hi
Well, i use Arch on my laptop. And there is one thing, which makes me wanna jump on it. The Lowlevel video output switch controls kernel module. I need this activated in order to switch between the projector and my laptop, I have my finals soon so its important this works as it should.
Would it be possible to enable this module in later pacman-versions of the kernel? At the time beeing, I would have to recompile everything my self. Which I have yet to become successful at, something is always wrong. But I`ll summarize what I would like to do:
#Build a kernel with this option, choosing it from grub at boot-time. But still have the "pacman-version" in case i mess up somethings up.
NOTE I use luksEncrypted root, does this option do anything to the kernel? Since the installer asks if you need to boot from an encrypted volume. Just asking...
Anyway, can I just download the kernel source. Run make menuconfig, activate the Low level video output switch controls. Then -> make modules_install? And then copy the kernel-version over to boot, and use it? Or what else?
Thank you so much for helping, took me ages discovering this feature was disabled on purpose.

Not before next weekend. My best guess is next Wednesday or later.

Using different video outputs?

Hello,
I was wondering if Director can use the different video
outputs on many video cards? I'd like to use the S-Video to send
video to a projector and then the VGA output to a monitor.

Out of the box... no.
Check this link.

Hope that helps.

8 video outputs working simultaneously

Hi,
I’m preparing a conference with a huge screen projection; It’s 60 meters width and 5 meters hight. This space demand six projectors working simultaneously; and every projector will cover a 10 meters width; the sixth part of the screen.
I will buy a MacPro and my question is the fallowing:
Can I have 8 video outputs with this specifications?
Mac Pro 2.66GHz Quad-Core Intel Xeon + 4x NVIDIA GeForce GT 120 512MB
Are the screens organized like 1 - 2 - 3 - 4 - 5 - 6 working as a big large screen?
Thanks a lot for the help
David

Theoretically this will work. The hardware itself will perform the task you've set it. Obviously the higher the resolution the less the likelihood is things will work smoothly.
That being said you'll possibly need some special software. Basically in OSX you can assign each port to be an 'independent' screen and arrange them in literally any configuration you want. Remember though 'maximizing' an application will only take up 1 screen (you can manually resize the app to cover more than one screen of course). I haven't looked into it but there may be a software product that easily lets you maximize applications across all your screens at once with a simple click of the button. You may have better luck in windows running in bootcamp finding said application / tool but I am nervous about how all those cards will perform under windows.
You may also find it cheaper to do something other than a Mac Pro with 4 cards. It sounds like you only actually need 3 cards (60 meters wide with each card putting out to 2 projects each of which covers 10 meters). Otherwise you can build a PC with Matrox Triple Head cards and just get 2. Lastly, your dimensions will be a little off. There aren't any natively supported resolutions of 2:1 but instead 16:9, 16:10, and 4:3. Basically I'm saying you'll have something a little higher than 5 meters if you do each projector to be 10m wide.
Good luck!

Using both video outputs

I am using both video outputs on the back of the mini, VGA and HDMI. Thes VGA is running to a projector and the HDMI is running to a computer monitor. I am also running Bootcamp WINDOWS 7. When I power up the Mac, the computer monitor goes to sleep and defaults to the projector as the main monitor. If I power on the projector first, before powering the computer on and then power the MAC on, it recongnizes the computer monitor as the default monitor. Why can't the MAC mini recognize the computer monitor(HDMI) as the default when both video outputs are connected? HELP!

Try putting the setup in Extended Desktop Mode (Mirroring off) and make the Monitor the main or primary display as shown in the following article's
