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?

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?

Problems connecting my MacBook Pro to a video projector

I have a MacBook Pro. I have used it many times to connect to a video projector and give presentations in my classroom. Lately, it is hit or miss concerning whether the laptop will give a signal to the computer. I can't figure out what I am doing wrong. I have followed the instructions in the MacBook guide.(Start with projector and laptop off, connect, turn on, etc. )
I am using the DVI to VGA adapter. I have also tried to use the function keys and manually tried to get it to detect displays. Can't think of what to do next. I gave up and hooked up a Windows computer and it worked.
Could it be the adapter? Does anyone have any ideas I can try? Thanks!

I have problems too with some projectors and the DVI--VGA adapter that came with my MBP. The projector is recognized by the computer, but does not show any signal.
With the help of Stéphane Madrau, who has written the excellent tool SwitchResX, I found out that the projector reports that it takes digital input when I connect the MacBook Pro, but analog when I connect it to my 12" PBG4. From the DDC information (collected with SwitchResX):
MacBook Pro, DVI--VGA:
Input signal & sync:
Digital
PBG4, miniDVI--VGA:
Input signal & sync:
Analog input with: 0.700V / 0.300V
Separate Sync
Composite Sync
Given that the VGA cable is analog only, I would think that the MBP tries (or rather, does) output digital signals only, which don't make it into the VGA cable. If I find a solution I will post it here.
The clue was that the computer did not report any vertical scan frequencies for the external display, while it did so for a projector that worked.

No signal via DVI to VGA adapter on my video projector Sharp PGM 15X

Hi there!
I have a big problem with my video projector. It´s connected via mini DVI to VGA adapter to
the projector. The problem is, Mac OSX decect the projector but there is no picture.
To resize the solution on both, or one of them doesn´t help.
When I use my Bootcamp and reboot with Windows XP there is a picture on the video projector.
I cant believe this.
What should I do to fix this problem?

I got my Mac Mini yesterday and I am having the exact same problem as you are having.
I've tried on two different TV's but it is just not sending a signal. Is it faulty?

Is there a way to predict which video projectors will not work with the 2012 MacBook Air using the Mini-display to VGA adapter?

I recently upgraded from a 2011 MBA to a 2012 MBA due to the larger capacity SSD. The 2011 MBA running Lion and Mountain Lion worked with every video projector for lectures. The new 2012 MBA is hit or miss with video projectors. It is not an adapter problem. I have multiple Apple mini-display to VGA adapters with the latest firmware. They all work just fine with the 2011 MBA. Re-starting the 2012 MBA with the adapter and projector connected has not helped.
It it not acceptable to have a laptop that works with projectors some of the time. Apple is aware of the problem. Is the only choice to go back to the 2011 MBA?
RC

I installed 10.8.2 update today with my 2012 MBA. The details of the update include: Resolves a video issue with some VGA projectors when connected to certain Mac notebooks.
I tried using the MBA with a video projector and it found the correct resolution and connected with the projector automatically. Using detect displays in the disoplay preference pane wasn't even necessary.
I hope this is the fix I have been waiting for with the 2012 MBA.
Thank you Apple.

Connecting an epson video projector via usb

I did this once before I had to get technical support when I did it that time as well, but now I have updated, re-formated and re-updated my system and do not remember the steps in order to be able to use an epson video projector to my MacBook Pro via an usb connection.

Welcome to Apple Discussions, Kgtalbott
If you can import DV from your Sony camcorder via Firewire, you Mac is recognizing your "camera/Firewire connection".
When the Sony is connected and turned on, if your Mac's Finder > Go > Utilities> System Profiler app will not show your Sony camera as a connected Firewire device, try the suggestions in What to do if your computer won't recognize a FireWire or USB device.
If you are having difficulty only with one particular application, let us know which app has the problem and whether that app works correctly with your MacBook Pro's built-in iSight.

Video projector (Toshiba TDP MT500)- no signal

Hello-
I have a problem with my external display (it's a toshiba MT500 video projector). It works fine with my iBook G4, using a DVI-VGA adapter, so I assumed it would be the same with my new MacBook, but alas no...
I called Toshiba, who were incredibly rude and patronising, and basically told me that they can afford not to care about the Mac users among their customers, as they are such a minority (which, by the way, makes no economic sense, as they also have a much higher buying power, proportionally, but nevermind...), and that there had to be a problem with my laptop.
The thing is, there is nothing wrong with it! it recognises the projector just fine, and does everything it should do. I tried it with my brand new iMac and it's exactly the same. I have tried every possible combination of turning on and off the MacBook and the projector, selecting all the different input on the projector, but nothing worked, the projected image remains blue, with no signal.
Please help!
PS: I connected it with a mini DVI-VGA adaptor, which I bought at my local Mac centre.

Thanks for the tip, but I've tried that too (every possible combination) and it just doesn't work I don't have the iBook anymore, but it was basically plug and play, no settings needed.
I've also tried the adapter to plug in my MacBook into an external monitor (on a PC at work), and it worked perfectly fine straight away, so there can't be anything wrong with it...
Any other idea?
I'd be really grateful!

IBook to video projector

In the past I have connected my iBook G4 to a video projector with the video adapter cable using an RCA cord from the adapter to the "video in" of the projector. The projector automatically recognizes the input and it works.
The past two times I have tried to use the same set up, it will not work. The video is not recognized by the projector. It works fine with the VGA(?) connector, but we are using two laptops and one needs to be plugged in via the Video In port on the projector.
Am running 10.4.6. Don't know if any OSX software updates are the problem or not. (I only need to do this kind of connection occassionaly, so I don't really know when the problem began.)
Anyone have any ideas???
I've tried using an RCA to S video cord, but the projection is blurry.
Thanks

I used to have a similar problem with any mac on my last hospital, it was weird, because the macs (about 25-30% of residents used macs there) didn't worked with the projector, and the Hospital's Vaios did worked on the same setting without a problem.
Finally I was able to track down the problem to a faulty cable that somehow the vaios could use, and the Macs couldn't (it was all twisted and it was very old). When we replaced the cable, every mac (and of course, every other computer) worked again with that projector.
My point is, you should check with another VGA cable, before blaming the video adapter or the videoport of the computer.
Good luck.

Using video created on iDVD on video projector

I burned a video in iDVD that I had created in Final Cut Express. It played on my computer and on the TV. However, when I went to show it on a video projector there was no sound. SOmeone who was a sound engineer checked the set up and couldn't understand why there was a problem. We ended up placing a mike next to the speaker on the projector and that worked. Is there an incompatibility or do I need to burn it differently to work with a video projector.

do I need to burn it differently to work with a video projector.
No
What did you have connected to the video projector to play the DVD?
We ended up placing a mike next to the speaker on the projector and that worked.
That sounds like the projector WAS playing the audio.

Mini-Div to Video projector

Hello Guys,
I have a problem! I hope u can help me.
So I have a McBookPro middle 2008 (mini-div) output for video signals.
now i want to connect it to a video projector and don't know wich adapter to use (mini-div to hdmi, mini-div to div, mini-div to vga)
(to share powerpoint files)
I hope u can help me
thanks

First, That's Mini-DVI (not DIV).
Second, you need a Mini-DVI-to-XXX adapter, where "XXX" is whatever input your projector requires. We can't tell you what that is, because we don't know what kind of projector you will be using.
If it just one projector that you need to use, look at the connectors or ask the owner.
If you will be traveling to a number of sites and using whatever projectors you happen to find there, you may need any or all of those adapters. Call ahead and ask what they have.

How do you crop QT file for projection on a video projector?

Trying to output QT files for playback on video projector in normal NTSC 4:3 aspect...the projector will be hooked up to a PC and play thru whatever inane video player the PC uses...therefore it will be displaying more of the image than a normal 4:3 frame....
problem is: in my FCP project I shifted some images in the 4:3 frame using the Motion tab...thererfore when they are played in QT player or on a computer, or thru a projector (as in this case) the extra bits of the image off to the side and top and bottom that would never be visible on a 4:3 frame are now visible...
if I crop the image, then I get a black box around the outside...do I resize the output file in terms of pixels or do I have to create a mask in QT to play without a black border?
Please help.

I see - you're concerned about blanking and other 'blackspace.'
If that's the case, try this:
Drop your QT movie into Compressor 3
Apply the DV-NTSC setting (under Advanced Format Conversions)
In the Geometry Pane, adjust the Crop values for the 4 edges to taste (I'd highly recommend scrubbing thru to make sure you've not over/undercropping).
I'd personally recommend dragging the red borders in the Preview window, just be aware of a small screen bug where it squishes the image (if only in the Preview window). To counteract that, hit the Back arrow button in the Preview window (top left), then hit the Forward button. Toggling between the source file (by hitting back) and destination file (by hit forward) allows the image to 'pop back' correctly.
If you were only worried about blanking - the black edges that cameras produce, then you'd only need to crop maybe 8 pixels from the left and right. But since you've got more stuff to worry about it, it's hard to suggest what to do, exactly. But remember to crop according to aspect ratio. That is, if you're taking 8 pixels off the left and right each, you've got to take 6 off the top and bottom each (aka keep the trims 4:3) otherwise you'll distort your image, however slightly.
Confirm that Frame Controls are activated and that Resize is set to Better. (This will dramatically increase encoding time, but otherwise, your output will be very poor). However, unless you're working on a very robust machine (or have a lot of time to kill), I would not adjust any setting to Best - it simply takes too long.
Submit. And wait for it.
You output will now be a 720x480 file with no blanking or other 'blackspace.' If you've got Frame Controls set right, you shouldn't see much, if any, reduction in image quality.

TX2 - 1370 US VIDEO DISPLAY problem ....

hello friends i am new to this forum.. i brought a new HP TX 2 - 1370 US laptop from amazon site in USA and now using it in INDIA since 10 months ... it came with AMD processor and ATI raedon HD 4200 graphics . it came with 4 GB DDR 2 ram .
it worked fine for 11 months .. i started using the laptop for more time these days around 10 hrs a day or so . yesterday morning when switched on the laptop the screen is blank and only quick launch buttons are blinking and caps lock buton .. i connected the laptop to a working monitor but no response .

i finally went to 3rd party repair shop and they said its due to defective video chip .. it needs to be replaced and they are getting many laptops with similar problems like this ...
is there any way to fix that ? wat am i to do so that i dont ge t these type of problems again ?
i am also using cooling fan for laptop an i am working in AC room with room temp set to 25degrees ...
lease can anyone tell me wat to do ?
shall i get it repaired by 3rd party as i cant send it to USA again .. are the video chips in this model really defective ?
thank you all ..........waiting for your responses....

Hello!
I just wanted to share my video display problem. Mine is a tx2-1375dx. When is turned ON cold, it shows rubbish, like the sequence shown next. The problem persists using an external video display or projector.
Then, instead, I warm up the back of the display with a hair dryer, not too much, but that feel the heat has transfered inside, the Tx2 runs just fine. I also keep a fan cooling pad underneath instead of having the inner fan run 24x7.
So I guess the video chip has a thermal sensor that is being signaled when the display is warm and then runs fine. This would mean part of the functionality of the video chip may have been compromised by heat on the motherboard.
Too bad a promising machine was so poorly designed inside. It becomes too hot to put on your lap, so is no longer a "laptop".
So now, my other thing on my backpack to work is a hair dryer!

Mini DVi to VGA : impossible to display to a video projector

hello !!!
I bought a MINI DVI to VGA adaptor and i as soon as i connect my videoprojector (Sanyo) to my Imac with the mini DVI-VGA adaptor, my Imac screen freezes and nothing appears on the video projector screen.
What can I do ?
Thanks

Not exactly, though you can reset the PMU of an iMac flat panel machine with a PowerPC G4 processor, reset the SMU of a G5 PowerPC-equipped platform, or reset the SMC of one driven by an intel processor.
Any corrupted settings stored which might affect your external video will be dealt with by those processes. Have you attached the adapter alone and seen this same outcome, or does it occur only when a VGA projector is attached to the adapter?

MSI K7N2 Delta-ILSR, Mouse problem & Video off problem solved!!!

I find the following information that I collected very interesting at the very least...
Here goes...
The video off problem that I was having was directly linked to the mouse. Here, let me explain the video off problem. In the BIOS Have the Standby mode set to S3. The problem occurred when I started windows, then went into standby, then started back up, then restarted the computer, the monitor would act as if it were in sleep mode, or rather there was no signal being sent to the monitor. Well the odd way I fixed that is by plugging in a standard 2 button PS/2 mouse. Also this fixed the issue with the mouse sometimes not working in windows.
Here is how I tested.
Logitech MX700 Cordless Optical Mouse, PS/2 & USB= failed.
Logitech iFeel Optical Mouse, USB= failed.
Microsoft Cordless Ball Mouse, PS/2= failed.
Standard Artec (Cheapy brand) Ball Mouse (With no wheel), PS/2= All issues fixed, and passed.
When I said failed I do not mean they didn't work, I mean they sometimes didn't work and also caused the Video off problem after restarting the computer.
Obviously it isn't the ports (PS/2 or USB) that are the problem, it is more like the mouse itself, and the amount of buttons in particular. As you can see above the only mouse that works correctly is the one that only has 2 buttons, the rest has 3 or more buttons along with a Wheel. The MX700 has 8 buttons + wheel, WOW!
Anyways I figure out it was the mouse, and not the memory.
Obviously MSI needs to make a patch for this mouse problem.
I'm still having a hard time believing that the mouse caused the video not to work, but it is true! I spend well over 5 hours testing this crap. Every time with the mice with more then 3 buttons it messed up, and every time with the 2 button old fashion mouse it worked flawlessly!
MSI, get to work on a new BIOS to fix this mess!!! :]

i used the ps/2 mouse in windows and the usb mouse when playing games.
you can get some trouble if you do it the way i did it.
i was in windows surfing and the pointer just jumped all over the screen.
when i looked on the other side under a table a friends little kid played with the usn mouse. )
bye
LOL, that isn't what I'm talking about.
There seems to be a problem with my motherboard accepting mice with more then 2 buttons. It works the first time, but if you restart the computer, the video goes off. If you have both installed, it still messed up.

'Source play' and 'audio-video sync' problems with PE8 on fast WIN7 64 bit computer

I am transferring Hi8 videos, about 2 hours long, to my WIN7 64 bit computer with PE8. [Dell Mobile Precision M4400 Computer Workstation (Intel Core 2 Duo T9900 500GB/4GB); NVIDIA Quadro FX 770M, 512MB] I seem to have several problems:
First, after importing the file (.avi), I get a message about ‘dropped frames.’
Secondly, when I try to play the video in the source monitor, the audio plays but the video doesn’t; it only shows the first frame [this is after waiting until the video is ?recognized? ] I can use the shift-arrow key and see that the video is there.
Thirdly, I can play the .avi file in other players, e.g., avidemux or PE pro CS5 on another computer. There, I see that the audio and video are not in sync; the audio can be up to 300 ms ahead of the video (as determined using avidemux).
Questions:
1. Why doesn’t the source monitor play the video? Is this a problem with PE8 (latest update as of 3 March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence?

"I think you're telling me you're using a backwards compatible Digital8 camcorder to capture your video as DV-AVIs. Is that right?" YES
"Are you using Premiere Elements to do this capturing?" YES, AS ABOVE PE8
"Go to the File menu and select Properties. It should show a standard DV codec being used for your video and audio."
WMP v12 is dumb. Under properties, media, it says 'video.' However, avidemux gave me the information state above: video -- Codec 4CC: dvsd, frame rate: 29.971 fps; audio -- codec: PCM, channels: Stereo, frequency: 48 kHz.
So, back to the Questions:
1. Why doesn’t the source monitor play the video? Is this a problem with PE8 (latest update as of 3 March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence?
