MBA external display video playback

I use MBA 2012 with Dell U2413 via miniDP to DP cable avilable from Dell. Everything works perfectly, full resolution and sharp image. Only thing that bothers me is when I play video in any program including from youtube. There is a purple blotch where ever video is playing (MBA or Dell). This's not a problem when not connected with external display. How to fix this problem?
Any suggestion is much appreciated.

Finally, I came up with the solution, the problem is at Dell monitor setting. In Display settings, Smart Video Enchance, turn it off completely solves the problem. Hope this may be useful for those having same problem as mine

Is there an app for video playback on external screen from ipad mini which avoids mirroring?

I want to play fullscreen video from ipad mini to external screens with a clean look and without without showing playback controls etc. I need to be able to play, pause, change the order of video tracks without affecting the external display as it's for playback of video backing tracks for a music show.
Does anybody know of any apps which do this? I'm looking at Portfolio for iPad at the moment which looks promising.

No.

Only FIREWIRE for playback on External Display???

Hi,
i'm still work on the setting of Preview on an External Display (TV). FCP only support FIREWIRE but NOT USB??? cause most of my Consumer Device only provide USB port.
No other way to set it up? Is the DVI output an good option (bypass FW device/converter)?
Thanks...really need help

Firewire only if you are working with DV or DVCPRO HD footage...that's it. All other formats require a capture card or external converter. USB is not designed for streaming video.
You can get a DVI converter...that will send a MONITOR signal out, and you can use Digital Cinema Preview, but that will be a low res output. Full res output require the external boxes or capture cards...or firewire if you are working with DV or DVCPRO HD.
Shane's Stock Answer #8: External Monitor Viewing
If you are working with DV, this is simple. First connect your computer to a camera or deck via firewire, Then connect the camera/deck to your TV/Monitor via RCA or S-Video.
Then start up your camera and tv, then open fcp.
Go to the View Menu, choose > External video > all frames
VIEW>Video playback should be Apple firewire NTSC (If you are using an NTSC set)
VIEW>Audio playback should be Audio follows Video
Techinially, this should send synched video to your TV
If for some reason you can't view your timeline on your external monitor, there are a few things to try:
1) Make sure that the camera/deck is connected and powered on BEFORE you open FCP.
2) In the Final Cut Pro menu select AUDIO/VIDEO Preferences and make sure your signal is being sent out thru Firewire DV.
3) Go to the menu and select VIEW>EXTERNAL>ALL FRAMES.
4) Click in the % box above the image and select FIT TO WINDOW.
5) Go to VIEW->refresh A/V devices
6) Make sure the Log & Capture window is closed
If you want it to play in both the canvas and the external monitor you need to go to the FINAL CUT PRO menu and select AUDIO/VIDIO settings and make sure MIRROR ON DESKTOP is selected under the PLAYBACK OUTPUT section.
If you are working with HDV footage, FCP 6 allows you to view this via firewire, but ONLY as downconverted DV. It won't look the best, but you can see it. To do this,
If you need to view any format other than DV at full resolution, then you need to look into capture cards. Several standard definition and high definition models are available from www.aja.com and www.decklink.com. With these options you'll need a proper monitor to view full broadcast colors, but all models allow for realtime standard definition downconvert, allowing you to view HD on an SD monitor.
The Matrox MXO is another option that is output only, but allows you to view your footage on an Apple Cinema Display at full broadcast quality.

Fullscreen video playback on external monitor (overlay problem?)

I want to watch videopodcasts via iTunes fullscreen on my external Monitor/TV. It works fine with Quicktime and WindowsMediaPlayer but iTunes doesn't play my Videos in Fullscreen on my external Monitor.
I had the idea it is because the overlay mode isn't siwtched on but I can't find where to setup the display mode of video playback in iTunes.
Can anybody help me?

oh, no...
i thouhght the iTunes Videoplayback would rely on Quicktime and thus it would be possible.
isn't there any other possibilty?

External Display : No Video

When I connect the MBA to an external display there appears to be no video sent to the display. The external display detects no video. I'm using the MBA VGA connector. When I check System Profiler it shows the proper external display as being connected.
When I connect the same video cable (different connector) to my iBook the external display works properly.
Any ideas? Could it be a bad VGA connector? HW problem? I plan to go by the genius bar tonight but I wanted to check if there was something I was missing on the MBA to properly connect it to an external monitor.
Thanks,
Jerry

Jerry,
I'm having exactly the same problem connecting to a Sharp Aquos display via the VGA adapter from Apple through a VGA to DVI cable to the DVI input on the TV. The MBA recognizes it is connected to a Sharp display. I tried selecting both analog and digital DVI, with no luck. I've had this work on another older laptop with the same VGA to DVI cable and TV. What did you find out from Apple?

Video Playback in synchronization to data display

I've read a bunch of topics about recording live video, but my question has to do with playback synchronized to a data display. I've got a simple black and white camera (RS170) already. I'm going to get some sort of capture board. I want to record video from this camera to the hard drive. The reason is that this video file needs to be analyzed later so I need to store it on disk instead of memory as it could be days later. While I'm recording video, another signal needs to be recorded. It could be anything really, let us say temperature for discussion. Assume everything is in place for this temp. acquisition.
Recording video to disk doesn't seem to be any problem. My question relates to playing this video back such that when you play it, you can also look at a data display of the recorded temperatures that happened at the same time as the video was recorded. If you were to drag the video slider manually (instead of just pressing play), the data display would also update accordingly. This essentially syncs the data display of temperature with the video picture you are seeing. Pressing play and just watching the video, the temp data would update itself with the correct historical values. Pressing pause on the video, would of course freeze the temp display to the value at that time. Wherever the video is, the temp data would have to display the correct historical value.
I would need to record possibly a few hours of video a day so disk space could be an issue if using uncompressed AVI format. I wouldn't have to save every days video file so I could eventually delete a bunch of the files. I'd just save the days video that produces interesting results to examine later. A number of video files might build up (a months worth?) before the directory is examined for possible deletes. I'd like some feedback on this too from someone who has tried uncompressed AVI versus something else that is compressed. Is performance OK if using compression?
The computer I'd be running this on is the latest workstation class machine from HP so it is a fairly powerful computer.
Is there any sample code of doing this video playback indexing to data signal display? I'm thinking there would have to be some function to know where the video is playing at all times and then historically retrieve the temperature data. Is there performance issues with this? I'd want it fairly accurate such that the smallest increment of a video frame (say 30 times a second) produced a proper data display for temperature. In reality, my signal will change faster than a typical temperature value would.

I doubt this will satisfy 100% of what you're looking for, but it should at least get the conversation started on developing some techniques we can use to syncronize acquired data playback (again, let's say temperature) with some external source. I don't know much about video playback, so I won't be able to help you much there, but I do know a lot about leveraging LabVIEW technology to play back data in real-time as best possible, while allowing the user (or the video playback itself) to dictate a specific position at any time, pause, etc...
My first recommendation would be to save your acquired temperature data as a Waveform. Waveform is more or less like a cluster with three elements: a 1D array of Y-values, an intial time (t0), and the time between samples (dt). You can use these three pieces of information to reconstitute when each sample was acquired and what the timing should be configured for to play these samples back in real time. Search the web for information on writing Waveforms to file and reading them. You should find plenty there (or post somewhere else ).
After that, we can use a Timed Loop for playback. Timed Loops allow you to set a desired Loop period. They also have a lot of other capabilities, such as setting priorities, handling the fact that your last loop didn't finish on time, etc. Here's a link with more info on Timed Loops. Other than that, Timed Loops can operate like regular while loops.
My next idea is to incorporate a current position that we keep track of. This could be, for instance, the index of the current element in the 1D Y-values array. If you want this to involve user interaction with the front panel (for instance, changing a Slider value to reflect the playback position), then you could use an event structure with a timeout case set to zero. Then update the temperature value and increment the current position in the timeout case.
You might take a look at the example I've written in LabVIEW 7.1 that "acquires" 5 seconds of sine wave data and plays it back in real time. The user can adjust the position or pause the playback at any time. Again, I don't know exactly how this would interface with video feedback. If you have more specifics about what method you will use to playback the video, maybe someone with more expertise in this area could help us out.

Video performance on external display

What Apple computer will perform the best on an external display?
I am using my Mac mainly for calibrated 1080p video playback.
I tend to come to the conclusion that I need a Mac pro for optimal performance on an external display? The mac mini could not produce flowing high bitrate 1080p video in iTunes. This was confirmed in an Apple shop. My iMac 27 inch i5 is perfect on the internal display but not external. And I read that the new Macbook pro is also better on internal than on external but perhaps good enough?
I go through all this trouble because as a video hobyist I am using a calibrated video beamer with my i1pro and found the cms that is supported on osx with the icc profiles very impressive. I need the cms because my beamer is a wide gamut beamer and uncalibrated the colors are to vivid. Using an external cms is expensive and difficult compared to the easy automated icc profile calibration in osx.

Hi,
I have tried several mkv's that I transcoded to iTunes with Quicktime. I used the fast option that only changes the container (save to film). The mkv's where like 16 GB perhaps not that high bitrates if you compare with DV?
But in the Apple store the quicktime demo's played good and the only explanation I can think of is the bitrate. On the internal display of my iMac they also played good. On the external display there where problems with 1080p24 and 1080p60. Only 1080i played good.
So I concluded that all my Mac's where to slow For my external 1080p beamer I even upgraded the memory of the mini to 4 GB with little result.
Do you still think that a faster disk might solve this problem? At this moment I am considering a Mac Pro or a Hackintosh.

External Video Playback Problem

When viewing material in the source viewer playback on my external monitor randomly freezes. The playback on my edit display is fine, only the external playback has issues. This started happening after upgrading to 7.
Content is DV and timeline and external display set to match.
Using ATI Radeon X1900 XT.

HELP... My external video freezes when ever I use my external 1920x1080 monitor. Everything was fine prior the upgrade to FCP 7.0.1 or maybe even 7.0 The previous thread said this is a known issue. Do you have any links to Apple addressing this problem or is Apple aware there is a problem? It started happening to my system back in middle of 2009. I thought the solution would be to upgraded my video card from a 256 NVIDIA P345 to ATI RADEON 1900 with 512 ram. This made it less jerkey but the problem is still very hard to live with. Can anyone shed some light on this issue? Thanks in advance.

Yoga 3 pro cant stream video on external display or laptop

Saw a previous post on this, didnt seem like it was fixed. Having real issues with hooking up to an external display, when the web browser (chrome) is extended to the external display, my internet lags hard...i cant even stream a vid on youtube.
I've disabled realtek (fixed cracking speakers) tried a completely new cord set up from micro hdmi to dvi...nothing works. When i drag the browser window back to the laptop screen, it works fine.
Ok, 5 min follow up: it seems im now having the similar issue with streaming video on my laptop screen....sound streams fine, the video seems to shake back and forth very quickly, runs, then shakes again...seems to only happen intermittenltly on the laptop...but display shows real lag and shake.
Solved!
Go to Solution.

Have you tried changing the screen resolution on the Yoga to something lower than what it is set on? A 1080i screen has a resolution of 1,920 × 1,080, my Yoga 3 Pro has a default resolution of 3200 x 1800. I have not tried connecting my Y3P to the TV yet, but the conversion could be causing an issue.

External display flashes and shows 'snow'. (Video of behaviour included)

Since yesterday, my Macbook Pro is acting strange. When I connect it to an external monitor, it usually works. Everything goes well for 10 to 30 minutes, and at some point the display starts tearing, showing snow, and flashing. These flashes get worse and worse, up till the point where I have to reboot. Rebooting seems to help a little. Whenever the laptop hasn't been used for a few minutes it works correctly again, for a short while. (This makes me conclude it's some sort of heat-related issue)
The issue is present on multiple monitors using different DVI cables. I only have one mini-displayport to dvi adapter, so the problem could be there too.
This problem does not affect the internal display of the macbook in any way.
Here is a short video showing the behaviour:
http://www.youtube.com/watch?v=4BotUqHb3dM
What should I do? Try to figure out wether it's the mbp or the connector or just bring it in for a repair. (It's less than a year old)

I have had similar issues with my 15" MBP. Occasionally my external monitor will go 1980s and display what looks like crappy tv reception.
Also, connecting or disconnecting an external display (via the single link mini display port to dvi adapter) has a tendency to lock up the entire machine (both displays black, won't respond to keyboard or mouse) until the power is cycled.
Also, my built in monitor has a habit of flickering/glitching lines.
These problems seem to happen regardless of which graphics card is active.

an external HD that had been on the desktop (i.e. I forgot to eject it
properly), started displaying video anomalies (lines); testing
(TechTool Deluxe 3.1.3) indicates the video is failing.
The graphics card is an ATI Radeon X1600. Is this reasonably
replaceable? If so, is the "MPC ClientPro 434 All In One ATI MXM X1600
PCIe 128MB Video Card" I found on eBay (for $25, used) essentially the
same unit?
My soldering skills are, sadly, poor.
And it only dawned on me a couple days ago that because this iMac does
not have a Core 2 Duo processor, it will not be able to enter the
"Lion" generation.
Thanks,

Video out to external display

Hello, Is there a way to get video out to an external display? I currently have a T5, but am getting a TX. Should be the same for each, though. Rregards, Karl
Post relates to: Palm TX

Just a quick FYI...T5 and TX both have a "normal" 3.5mm audio jack.
Video will be a problem though. It's a shame my cheap little Insignia media player can output Audio and Video via a simple cable.

MBA not always recognizes external display after sleep

Hi,
I have a 2011 MBA and use it on a external display (Dell 2709w) with the lid open. The issue with this MBA is that after sleep it often (every second time I wake it up) doesn't show anything on my external monitor. In order that the external monitor works again I have to plug the DVI cord out and in or press recognize monitors under monitor settings.
I also did a PMC and SMC reset but both did not help.
I have also done a complete reinstall witch did not help as well.
I also did a test with a MBA from a friend (exact same model) and his always works with the external display after sleep while mine only works every second time.
Could this be a hardware defect? sound pretty strange to me, but who knows...

I have managed to make the Apple Hardware test by just pressing "D" while restarting. The test, however, did not find any error - but this does not surprise me as I think it only tests the ram.

Video playback on external monitor

I have a problem with video playing on my external monitor.
I have been editing a 30 second commercial with several split screens and quad screens. After my last render, the video no longer plays on the external monitor. A frame plays, and then it freezes. I went thru the "Stock Answers" section and played with the RT settings and the memory/cache settings. Nothing seemed to make a difference. I also opened some older projects and they will not play thru the external monitor either. Finally, another note that may offer some clues is that when you print to tape it sometimes plays perfectly and other times it does not.
Any help provided will be greatly appreciated!

S-Video vs VGA on external display

Just wanted to get yall's opinon on running S-Video vs VGA on a ViewSonic 26" LCD HDTV. Im looking at picking one of these up. My guess is that VGA would be better, but wanted to get opinonson people whom have used external displays. I thought about going this way instead of a 20 inc LCD with DVI input. So any suggestions would be helpful.
Thanks
Steve

Are you certain it's really "VGA"? It's not a "composite" connection? The "yellow" connection that looks just like the red & white audio connections? A TV with a VGA connection would be a kind of odd thing. But any one that has s-video would probably also have composite connections. S-video would be better than composite, if you have a choice between the two, but VGA would be even better.
You will also need an to go from your MBP's headphone port to the audio-in on the TV. Unless you want to listen to the audio from your laptop.
