Video Playback on extended desktop

I have Windows Vista with a BFG nVidia 9800GTX video card. I have extended the desktop onto the second output of the video card with the intent of using a DVI to HDMI converter to hook this up to my TV and play video back over it.
It is possible to get iTunes (currently 8.2.1.6) to play video back on the extended desktop by default? When I have it on the main desktop, video plays back there. When I move iTunes over to the extended desktop then start playing, I don't seem to get video at all (both screens go blank but no video).
Thanks.

There is really no dependencie on whether the image being sent through the switch is the primary desktop or the extended desktop. The switch will have no awareness of this. What's going to matter is if you find a video switch compatible with your interfaces and monitor. Are they DVI?

HT5019 How do I play a video on my extended desktop (my TV) and still use my desktop to surf, work, etc.?

I have created the extended desktop, but don't know how to get the video on to the extended desktop, which displays on my TV. I can't seem to play a file on my tv, and use my desktop on the mac to surf, work, etc. You seem to be able to use either ione or the other desktop - not both at once.
I was easily able to do this on my old PC!

Apple menu -> System Preferences -> Displays
Dragging the menubar on the image representing one display to the image representing the second display.
As most programs send the signal for video to the primary display this will often free up the other display for using while you play video. You can always use another video playback software, or just maximize the video playback software's window, instead of going fullscreen. It really depends on the software you are using to play videos.

Video switch and extended desktop

Is it possible to use a video switch for my G4 and G5 with the display it controls being the only monitor for the G4 and the extended desktop for the G5?

What's the keyboard shortcut for switching betwen video mirroring and extended desktop screens in a imac intel?

I've a iMac with broken display that i can used by external monitor, but... this display shows only background image (no menus, no finder icons). How can turn the display options from System preferences without acces it?

CMD F1 is the shortcut to toggle between Mirror and extended.

Mapping Video Playback to Keyboard Functions

Periodically I need to change my Video Playback to my second monitor by going to View > Video Playback > Digital Cinema Desktop PREVIEW.
I once did it to "Preview - MAIN" in Motion and couldn't get it to come off unless I trashed my preferences. I'm rather concerned that in a sleepy moment my mouse will slip and I'll hit MAIN. Is there a way to map these functions (or any other menu combinations) to the Keyboard so I can just bring it up with a simple keystroke? Or is it simple called something particular in the Keyboard layout that I haven't figured out yet?
Thanks
Joel

The shortcut exists already. Command & F12 keys.

ITunes breaks Airplay extend desktop via Apple TV

Hi there, using my MPBr 15in with Yosemite installed and an Apple TV.
I have been watching photoshop tutorials in an iTunes playlist via extended desktop (Video played on extended desktop on TV, I'm following along with Photoshop on my mac).
I had put my mac on charge and did some things for a while, came back and went to continue my tutorials. But for some unknown reason when I select play in iTunes, instead of just playing on the extended desktop like it was earlier, iTunes quits the extended mode, 'sends' the video to the Apple TV which is a bit of a bumpier process then I'd like. Not to mention it needs to 'buffer' the video each time the next one is played. The worst issue is that the video is zoomed in too far, meaning I cannot see the photoshop tools or the menus along the top and no way to change it (it seems at least). I could forgo the Airplay streaming if it didn't have that issue.
No Apple account is signed in to the Apple TV.
I have tried changing a couple settings in Apple TV (including overscan settings on/off) to no avail. Also changed iTunes setting of Airplay that appears next to the volume slider. No matter what I try when I play the video, extended desktop mode turns off and iTunes streams just the video to Apple TV, also meaning I have to completely disconnect from Apple TV and reconnect again.
So my question is, how do I force iTunes to not use Airplay streaming when I have specifically configured the computer to extend the desktop? I want to extend the desktop!! Using the multiple desktop feature is useful!
Why does it assume I want to stream it independently rather than keep the second desktop?
Why has it done it now, instead of before? I never pressed anything that I know of. It just decided to do it.
If for whatever reason there is no way to turn this auto configuration off, how do I stream the video so it does not cut off the edges?
Thanks in advance. If I figure it out I'll be sure to post what I found here.

Adobe AIR Desktop Application - HD Video Playback

Hello everyone,
I am new to the forums. Hope I am posting in the correct one.
I have been doing AS3 development for last 2 years. But recently I had to implement a HD Video playback in windows. I was happy to know that StageVideo helps in that case. So I started coding and created projector (not with Adobe AIR , but to play with Flash StandAlone player). Was working great , playing 3840*1080 video with ease, awesome performance. But the problem came when I had to switch to fullscreen in that program. We were using 2 Monitors with extended desktop to give 3840x1080 resolution. The Flash could switch only to one screen. I leanred a new thing , Flash just can not switch fullscreen on two screens, be it standalone/web.
Then I came across AIR , saw on some forums that with NativeWindow class you can pretty easily run a AIR app fullscreen on 2 different monitors. I thought awesome ! I installed Flash Develop and got started with AIR 3.7 SDK. when I ported my AS3 code for AIR app , came to know that the stageVideo does not work here (that was completely unexpected!). So Now I am confused which path to take as Flash can not go fullscreen on dual monitors, and AIR can not use stageVideo.
Any help will be appriciated. Thanks in advance.
Edit -
The StageVideo Class seems available , but it returns the stage.stageVideos.length as 0. Attached a StageVideoAvailabiliityEvent to stage but seems it never is available. Any other way to play HD Video ? Native flash.media.Video is not able to handle such big video.

Extended desktop video troubles

I have a 20" imac with a 24" extended desktop and I am loving it. There's just one thing that is very annoying. I got the second monitor because I like to watch videos while I write and search the web. but most of the video sites I go to won't stay in full screen when I click the mouse. So I'm forced to watch videos that take up only 1/4 of the screen. On many sites I can zoom into the website, but this often creates a jittery, blockiness that isn't there when the video is set to full screen.
So my question is, how can I get my browser to not jump out of fullscreen when I use the other monitor? Is there a certain browser that has that kind of option? Is there an app for my computer that will let me do that? Do I not understand something fundamental about changing video settings? Or am I completely out of luck?
I'm having this problem on sites like youtube, all the network sites, megavideo wisevid,dailymotion, zshare,ninjavideo, etc etc. Pretty much the only site that I don't have the problem with is Hulu, of which I can either use Hulu Desktop or I can pop the video out and then expand it to the size of my screen.
So I guess another question is, if I can't do something that would uniformly fix the problem for all the sites, are there any more programs like Hulu Desktop (besides netflix) that are ideal for watching on an extended desktop?

And there's one more question I was hoping to get answered that I forgot to mention.
Is there a way to dim one screen to black while the other continues to play a video? I know that frontrow does it automatically, and quicktime and vlc both do it, but I would like to be able to do it easily on my own command--maybe with quicksilver (i'm not using the program yet but plan to get used to it).

My Airplay is delivering Audio but no Video (black screen). The drop down box has a new selection "use airplay to; it does not let me select 'Mirror my IMac', it is stuck on 'extend desktop' any suggestions appreciated.

When I launch a video from Finder the video is not visible, it's like it's playing on an extended desktop but I can't see the other screen - what is going on?

Hi Dan - I'm not sure I know what you mean by 'kick in Expose', can you please explain?
It's a weird one as it doesn't happen all the time. Could it have anything to do with running Apple TV and the MacBook 'thinking' there is another display (extended desktop) and playing the video there?

Getting a video card that supports extended desktop mode: AGP? PCI?

Hi guys and gals (and everything in between),
One of the reasons I got a Power Mac not so long ago was the convenience of using two or more displays at once, but then I discovered that the stock ATI Rage 128 in my Gigabit 450 (dual) does not support two displays. (I discovered it the hard way, when I connected a recently acquired Studio display to it, and my trusty CRT stopped getting a signal.)
I won't be using the computer for games, design or anything graphics intensive, mostly word processing (I'm a translator/editor/writer by trade), so I do not need the high end of the video card spectrum --just an AGP card that could allow me to work on extended desktop mode, preferably with an ADC connector. Would a Radeon 7500 suffice?
Or maybe a PCI card? I have read a lot in this forums against getting a PCI card, because of the 33 Mhz bottleneck, but wouldn't it work well enough for checking email and working on 2 or 3 documents at once?
Any help with this will be greatly appreciated!
Peace.

Thanks, PB PM.
I also did a little research in the forums and elsewhere (by the way, your posts have been really helpful to me, very knowledgeable and well-documented), and ended up buying a Radeon 7000 PCI for hooking up my VGA monitor, as a cheap solution to my problem.
Thanks again!

Extended Desktop (video out) issues

Hi, I'm having trouble figuring out how to set up an extended desktop onto another monitor using my iMac G5, 1.8 GHz. Mirroring the desktop is fine, and the help screen says that if there's no "Arrangement" option, then it won't be able to set up the extended desktop. I don't see this, but I seem to remember having this computer use a second display as an extended desktop before. Is there a solution for this or am I destined for mirrored desktops only?

yep, sounds like your computer doesn't support spanning, only mirroring...
As someone else said there is a firmware extension script called 'screen spanning doctor' (google it). I wouldn't call it a hack as you can remove it by resetting your pram, i think... however, it can mess your computer up, so really think before you want to use it!!

Tablet PC calibration error in Adobe Photoshop and Illustrator CS3 whilst in Extended Desktop Mode

Hey everyone!
I've run into a snag which hasn't bugged me before because I never used a second monitor, but now that I do, Photoshop and Illustrator don't function properly.
I am running my Adobe products on my Lenovo X61 Thinkpad Tablet, which is Wacom PenEnabled. It's got the basic digitizer pen and pen pressure features, no stylus tilt or anything.
Whenever I run Photoshop or Illustrator in Extended Desktop Mode so I can have a different window open on my external monitor and the Adobe app on my tablet screen, my stylus goes strange. It seems to think that the extended desktop is part of the Adobe window, so when I move my stylus to draw, the cursor will appear on the external monitor, usually proportionate to the size of the screen...ie. It interprets the external and tablet screens as one desktop and the top left corner of my tablet screen is the top left of my external, whilst the bottom right on tablet IS the bottom right on tablet, if that makes any sense...sorry.
So I can't draw anything in photosho unless I set it back to standard desktop mode, or mirrored desktop. I've searched over the net and these forums and I can't find a fix for this. I was walking in harvey norman the other day and the Wacom Cintiq 12" was there on display, and it had the same issue with extended desktop and photoshop.
Has anyone had this issue before and/or does anyone know of a fix for it? I'll keep searching around and playing with the computer until I fix it and I'll post any solutions I find here if noone else has one.
My system details are:
Abobe Photoshop CS3 10.0.0
Adobe Illustrator CS3 13.0.0
OS: Windows Vista Build 6001, Service Pack 1, 32bit
RAM: 2GB
HD: 18.2GB free Disk Space (out of 66.3GB on the Active Partition)
Video: Intel GMA: Mobile Intel(R) 965 Express Chipset Family

I'm using an HP tx2011au tablet pc, using adobe flash cs3 and have the exact same problem. it becomes decalibrated only while the flash window is open, and only while flash has a file open, and only when using an extended desktop. even if flash is open and it has no files open it works fine.

How can i monitor network traffic to debug video playback issues from a NAS?

I am having problems playing videos on my new Mini that i am using as an HTPC.
I have a brand new Mac Mini running Lion with a 2.7 i7 processor and 8GB of RAM with a wired connection to a switch. .
My switch is a NETGEAR ProSafe GS108T-200NAS set to default settings. I haven't had a chance to start messing with VLAN settings or anything else. There is a bit of a learning curve on my part on this end.
My NAS is a ReadyNAS Pro (RNDP6000) with 3 x 1 TB hitachi ultrastar (HUA722010CLA330) drives and a 1.5 TB seagate (ST31500341AS) drive setup in RAID config using X-RAID2.
The problem I am having is video playback when accessing large video files off of the NAS. These are typically 1080 HD mkv files.
I have tested movies as small as 7.5GB with only slight stutters on occasion. I tried a 10.5GB movie and the stalling was much more pronounced. Movies larger than 11GB are completely unwatchable stalling every minute or so.
I have also tried large movies on the local drive and that is not a problem at all - they play back just fine. Beautiful playback in hidef. Mind you, some of these are the same files that were stalling over the network.
I have also noticed that some other network devices get kicked off the network when a movie is playing.
I think it has something to do with the transfer speed of files over the network and the switch - i am no expert at this mind you.
I am wondering if there is some sort of utility that i can use to monitor network activity on the mini so that i can fix my problem. Or has anyone made chages in their switch settings to optimize data trasfer speeds.
Any advice or recommendations on.
Thank you all!

OK, I did a couple of things and ran things a couple of times.
First what I did settings wise:
I enabled jumbo frames on the Mac Mini, ReadyNAS Pro, and the Netgear GS108T switch. All with MTU set to 9000.
I went ahead and enabled jumbo frames on the rest of the computers on the network just in case.
After these changes I ran into the same problems with videos timing out - very annoying and frustrating as you can imagine.
Then I started playing with device configurations. My original configuration was NAS > Netgear switch > Mac Mini. I went ahead and switched the switch to an Airport Extreme I have as my WAP and the setup looked like this - NAS > Airport Extreme > Mac Mini.
Well, long story short, no go. It appears to me that the NAS is the one having issues providing the necessary data at the proper speed. I also tried playing sopme movies off of the NAS onto a desktop i have and had the same issues - choppy frames and crashing movies. I even tried connecting wirelessly to see if that would work.
BTW, I have the Mac accessing the file system using CIFS.
I don't know what else I could do.
I am going to have to go to the Netgear forums to see if i can figure this out. Hopefully, I can get things going to be able to help some people out.
If anyone has any ideas, they would be greatly appreciated.
My only other alternative is spending $2000 for the thunderbolt capable NAS that Apple sells - it's only money!

Apple TV 2 choppy video playback when mirroring from Macbook Pro (Yosemite) and Macbook Air (Yosemite) but not iOS devices

Video playback is choppy (cuts out every 30-45 seconds) when air playing from both my MacBook Air 1.3 GHz Intel Core i5 running Yosemite and my husbands new MacBook Pro, but runs perfectly when mirroring from any of our iOS devices (iPhone 6+, iPad mini 3, etc.) We have Apple TV 2. This problem just started a few weeks ago, was working fine around Christmas. The problem seems to have coincidentally started right after our son tried plugging in and setting up his Chromecast on our tv. I disconnected the Chromecast, but we still have the problem. All of our software if up to date and I've tried disconnecting blue tooth, we do not have a microwave and our wifi network has a very strong signal. We have an Airport Extreme base station. Is there a solution to our problem?

Hi leahmturner,
I see that you are experiencing an issue with choppiness while AirPlay Mirroring from your computers to your Apple TV. I have an article that contains some helpful troubleshooting steps for you regarding this issue:
About AirPlay Mirroring in OS X - Apple Support
http://support.apple.com/en-us/HT201343
Optimizing image quality
Resolution matching modes
You can choose between two desktop resolution matching modes that let you select which display will have the best image. When AirPlay Mirroring is turned on, select an option under "Match Desktop Size To:" in the AirPlay Mirroring menu extra.
Match Desktop Size To: Apple TV
AirPlay Mirroring changes the desktop resolution to best match your Apple TV, resulting in a 16:9 image that fills the HDTV screen. This setting often produces the sharpest image on the HDTV. The aspect ratio and/or resolution of the built-in Mac display may change to accommodate the Apple TV.
Match Desktop Size To: This Mac
AirPlay Mirroring scales the contents of the desktop to fit on the Apple TV, leaving the resolution of your Mac's display unchanged. Use this setting for the sharpest image on your Mac's display. Depending on your Mac model, the resulting image may not fill the HDTV screen.
Troubleshooting AirPlay Mirroring
If you don't see mirroring options
If your Mac and Apple TV are on the same network, but no AirPlay Mirroring menu appears, your Apple TV may be asleep. Simply press a button on your Apple TV remote to wake it up. After a few seconds, the AirPlay Mirroring menu extra appears. If you still don't see the options you expect, make sure your Apple TV has the current software update installed. Also make sure that you have the "Show mirroring options in the menu bar when available" option selected in the Displays pane of System Preferences.
If the menu bar or Dock is cropped
Some HDTVs have bezels that cover a small percentage of the screen. This can result in a slight cropping of a full-resolution HDTV image. Depending on the HDTV model, AirPlay Mirroring may automatically adjust the picture size to prevent cropping. If you are using OS X Mountain Lion or later, and you see cropping of the menu bar or Dock when using AirPlay Mirroring, toggle the Overscan correction option in Displays preferences.
Minimize video post-processing
HDTVs often apply picture quality enhancements intended to improve the look of film and video sources. In some cases, these enhancements can lead to over-sharpening artifacts when displaying your Mac desktop. Some HDTV models have built-in settings to change or disable the enhancements for use with a computer (computer, presentation, or game modes). Otherwise, the controls for sharpness, detail enhancement and noise reduction can be used to optimize the appearance of the Mac desktop. Consult your HDTV’s manual for guidance on the appropriate settings for use with a computer.
Firewall security settings
If you use a firewall, make sure the following firewall security options have been set to allow AirPlay Mirroring to work:
Choose System Preferences from the Apple menu ().
Click Security & Privacy, then click Firewall.
Click the lock icon to unlock it if it's locked, then type an administrator name and password.
Click Firewall Options.
Deselect (uncheck) the “Block all incoming connections” checkbox.
Select (check) the “Automatically allow signed software to receive incoming connections” checkbox.
Thanks for coming to the Apple Support Communities!
Regards,
Braden
