Play iMovie on 2nd Monitor

I connected my Mac to my home theater receiver via HDMI cable in hopes of watching my iMovies on my big screen. It's currently set up as dual monitors, so that my primary monitor (iMac) is on the left and my home theater projector (2nd monitor) is on the right (not mirrored). With this setup, is there an adjustment I can make to run iMovie on my primary monitor, but when I hit the play button, have it show up full screen on the 2nd monitor (big screen)? I'm hoping for this to work similar to Powerpoint, which shows the presenter view on the primary monitor and the presenter view on the 2nd monitor. Any and all help is greatly appreciated!

Note that you need to have the second monitor already plugged in before the option to use viewer on secondary display will show from within iMovie (pre- v10.0).
But as Gaudeamus mentioned, this option seems to have completely disappered under version 10.0, which is extremely disappointing, and frustrating, as I have an iMac set up with a second monitor specifically for that one purpose!
(but like the new version other than that, and am getting used to some of the layout changes).

Watch fullscreen movie on 2nd monitor & work on my MBP @ the same time?

I hooked up a 2nd monitor to my MBP (mini to VGA) and figured out how to have an extended desktop. It's a little tricky adjusting where the pointer will be (I don't totally understand it, but with trial and error and lots of persistence, I finally got it to ALMOST be set up the way I'd like).
I have a movie (.avi file) playing on the 2nd monitor and I'm able to work on my MBP, but I can't figure out how to view the movie fullscreen because when I get the 2nd monitor fullscreen, my MBP screen goes fullscreen as well (and of course the dock and any form of control disappear as my MBP screen is just dark and blank).
Does anyone know the trick to getting the setup that I want? FULLSCREEN 2nd monitor to watch .avi files while working on my MBP???
I could really use some help on this one! THANK YOU, oh knowledgeable one(s) who reply!!!

You won't be able to do it with the included QuickTime media player. But it can be done with other media players like MPlayer or VLC I am pretty sure. Haven't had this exact need myself but have seen other similar threads and recall the above being recommended. Good luck.

Flash Player freezes on 2nd monitor while playing fullscreen game on 1st one

Flash Player freezes (shows something like slideshow with frame rate near 1-2 per sec, everything is ok with sound) on 2nd monitor while playing fullscreen game on 1st one.
Windows 8, flash player 12, chrome.
Tried to use other versions of flashplaers, other browsers - didnt help me.
SOLVED: my computer for some reason didnt want to download updates. that was the reason of this problem.
Thanks in advance.

ITunes 9, no way to play fullscreen video in 2nd monitor?

In iTunes 8, videos would play fullscreen in whatever monitor the iTunes application window was opened to. In iTunes 9 this doesn't seem to matter, it's only playing in the Main monitor (monitor with menu bar).
There's a script here:
http://theappleblog.com/2009/07/29/workaround-itunes-video-and-dual-screens/
That sends videos out to QuickTime which has preferences which allow you to select what monitor to play full screen videos on, but I'd really like this back in iTunes...
Any ideas out there?

I found a little bit or a work around... you can go into preferences under the "Playback" tab and select "Play Movies and TV Shows: in a separate window" and it will play full screen in the monitor you have it on. You can also right/control click (or "view" menu) and select fit to screen to get a near full screen experience while being able to work on the other monitor.
You are mistaken. You can only use fit to screen. Even so, your work around is a colossal waste of time as you could simply drag the video to the other screen much much quicker than opening the preferences and making that change.

MacBook Pro performance issues w/2nd monitor and FCP7

I have this MacBook Pro bought brand-new in January 2010:
Model Name: MacBook Pro
Model Identifier: MacBookPro5,2
Processor Name: Intel Core 2 Duo
Processor Speed: 3.06 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 6 MB
Memory: 8 GB
Bus Speed: 1.07 GHz
and until today had never attached a second monitor to it. Today I hooked up my Samsung 24" to do some dual screen editing in Final Cut 7.0.3. I was unable to play back my video at full speed in the second monitor, and after a few seconds of skippy playback I'd get that error message about unable to play back video at full speed and to check my RT settings. I was using a Mini DisplayPort to DVI adapter. My computer has no issues playing the video in the laptop's monitor at any resolution and any quality settings (I've never changed the RT settings or anything else in the menu ever but I tried every combination this time). I then tried using my TV as a 2nd monitor with an HDMI adapter. Same performance issues. I then tried my friend's newer 13" MBP 8,1 and it performed flawlessly with the same project & footage. I feel like my $3,000 computer should outperform a $1,200 one even if mine is a year and a half older. Any advice?

Wow, you posted this perfectly to coincide with an identical problem, albeit using Logic Pro 9.1.5 rather than FCP.
Last week, I purchased a 23" external monitor to use alongside my "flagship" 2011 15" hi-res, 2.3 i7 Macbook Pro with 8Gb of RAM.
It is connected via a mini-DVI to D-sub analog (not that that should matter?) and all appeared fine.
The first issue I had was with my MBP's fan now running CONSTANTLY, when I have the second monitor attached. Even when the machine is completely idle.
When using the machine to record audio, this is a fairly hefty problem and not something I had anticipated - indeed why would I anticipate such a thing?
What is far, far worse though is that over the last few days I have had repeated problems with performance drop-outs and errors in Logic and I have trying to fathom out why. Realising that the only major system change made, was the above monitor connection, I ran some tests.
I restarted my MBP, no other apps were running and with my new 23" monitor attached acting as main display with MBP built in display on as secondary
I loaded up a fairly demanding Logic project which was hitting 40% to 60% CPU usage when using the built in MBP display last week
I ran activity monitor and had CPU usage history open
The above project now repeatedly overloads and playback halts in a given 8 bar section - with CPU at 80% most of the time
I disconnected the external display, no shut down, I just let the machine switch to the built in 15".
Started the same project, the same 8 bar section and hey presto - CPU usage back down to 40% to 60%
The above was reflected in the CPU usage history with the graph showing CPU use down by about a half, when running this Logic project WITHOUT the external display.
There is a very useful benchmark Logic project that has been used as a test by many users to gauge Logic performance on given Apple hardware.
The project has about 100 tracks pre-configured with CPU intensive plugins, designed to tax the CPU.
The idea is that you load up the project with tracks muted, press play and then unmute the tracks steadily until Logic us unable to play contiunously because of a system performance error.
On my MBP, with the external monitor NOT attached, I can play back around 50 of the audio tracks in this benchmark project.
With the monitor attached, I can get about 22 tracks playing.... which is actually a far worse a performance drop (-50% I think!?) than with the first example!
I did also try with just the external monitor attached and not the MBP display and performance was about 10% better than with dual monitors - so still extremely poor, to say the least.
This machine is the flagship MBP and has a dedicated AMD Radeon HD6750 GPU which should take care of most if not ALL graphics processing - I mean it's capable of running some pretty demanding games!
Putting aside the issue of constant fan noise, there is no reason AT ALL, why using an external monitor should tax the i7 CPU this way - it's not as though Logic is graphically demanding... far from it.
I am on 10.6.8, Logic 9.1.5, all apps up to date via "Software Update".
I will of course, be contacting Apple...

HOw to add a 2nd monitor to my DX4380- UR22

I only have my HDMI open and my monitr is an older version using a SVGA
This question was solved.
View Solution.

Hello there ArsenalOC1886!: to answer this question specfically
why not buy a cable that has the HDMI on one end{the PC} & a SVGA at the other(the 2nd monitor)
or get a HDMI\SVGA adapter at your local computer shop
with plug & play being as advanced as it is itshould work unless it's incompatible
good luck

2nd monitor went black after upgrading on macbook pro

Ive read post; however, i need help with getting 2nd mointor to work. it was working fine before upgrade but now jsut black. I was hoping there was a new solution to fix this thuderbolt / 2nd monitor thing. Im not comutuer tec. guy so I was hoping the apple systems where a good plug and play.
any help out there??
thanks

My best guess is that you have fried the RAM with static electricity charged up in your body. According to OGELTHORPE a beep on startup is because of no RAM, if when installing you did not do it correctly, you could have fried the RAM, which then your mac will not recognize it. The same with the old RAM, if you tried to re-install it and didn't pull up your sleeve and rest your arm on the inside of the chassis, then it is fried, or if you didn't wear an ESD band and connect it to the the chassis, then it is fried.
Seen as though you can't startup your mac, I can't say to do an AHT, buy some new ram, and start with the lowest one you can, so its cheap for ya use a different company incase is that;) Crucial.com is really good, I got an 8gb upgrade from 2gb. Let me tell you, it's great!

Clitching H264 Playback on 2nd monitor - 17" MacBook Pro/NVIDIA

I have used Keynote professionally for many years, and often use H264 compressed videos (that I have created in After Effects). This has always worked very well until the last few weeks when I noticed that every now and then there is a glitch in the playback of H264 movies when a 2nd monitor/video projector is attached.
Glitch description: A completely random flash/breakup of the image that lasts for single frame - similar to the old flash frame you used to get when playing back MPEG2 movies in PowerPoint. This does not cause the video to stop playing, but is annoying when using it in a profesional presentation. It is also completely random and occurs at least once a minute during playback. This only occurs on the new MacBook Pro's that have the NVIDIA graphics card. It does not occur when using the laptop's LCD display only - ie: no 2nd output used. It does occur on the laptop's LCD if a second display/projecter is plugged in. This does also not occur on my ATI equiped MacBook Pro 15" or my G5 or my iMac.
It appears to be a problem with the NVIDIA card.

hi!
i got the same problem with the 15 inch 2.4 Macbook Pro and
Digital Cinama Display through Final Cut Pro.
Looking like a NVIDIA driver problem - hoping for leopard............

Disabling Spaces & Expose on 2nd Monitor

Does anyone know if there is a way to disable spaces and expose on a 2nd monitor? I want the 2nd screen to run a keynote presentation and not be affected by my activities on the first screen.
Thanks,
Pete

Having played around with the two monitor configuration for a few days now, I realized that what I really need is a way to make them run independent of each other, essentially running the second monitor as a separate tv monitor for movies and slide shows. So far I haven't found a way to do this.
Also, whenever I play a Keynote presentation, it takes over both screens in one way or another and Apple didn't seem to have any idea of a way to change this. Is there a different way I could connect them that might make them more independent of each other?

Can't run flash player in full screen on 2nd monitor

Hi all! I have a laptop with dual video displays. The main
display is the laptop's LCD and the 2nd display is a 19" LCD
connected via VGA cable. I want to let a Flash movie loop endlessly
on the second monitor while I continue to work on the laptop. When
I drag Flash Player 8 over to the 2nd monitor and start the movie,
I can hit maxmize and it will take up the entire 2nd montior as it
should...with the file options and boarder around as expected. I
then hit Ctrl-F to go full screen and it snaps directly to the
laptop's primary monitor. I tried it at work where my desktop has 2
displays and the same thing happens. I need to force Flash player
to run full screen on the 2nd monitor and cannot find a way to
accomplish this. Any help is appreciated because it's driving me
nuts. I can always make the external monitor my primary but then
the start button and all my icons move there too and that is not
acceptable. Thanx!

Seriously? No one has any thoughts about this? I can't
believe I would be the first to come across this issue.

HT1338 cannot connect my MacBook Air to a projector -does not detect and 2nd monitor. I have a new Mini port to VGA cable made by apple. When I read online I see that many people have the same problem - Is this an Apple defect??????????????????

I cannot connect my MacBook Air to a projector - It will not detect a 2nd monitor or display. I am using an Apple made Mini Display port to VGA adapter. As I read online I see that many other peple are having the same problem. Is this an Apple defect!!???? If so it just burst the bubble about how great macs are. I never had a problem with that on a PC. I hope I am wrong. What can you tell me?

Hi There,
I have had the exact same issue but with a projector.
The issue lies with Mountian Lion 10.8.2.
I tried many a combination with no luck to get HDMI working.
Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
Bought my macbook home and voila, now displaying through my projector.
There is a small graphics update after 10.8.1 which seems to be the cause.
Hope this helps.
Thanks.

2nd Monitor won't work

I bought a Pavillion p6210f last week with Win7 loaded to replace my Dell/Vista. I was using two monitors with a VGA port and DVI port on the old PC, so I tried plugging in the same on my new HP and the DVI would not fit. In examining the pins I found that, althought the Manual said DVI, but the plug has the pin/bar arrangement of a DVI-D. So, I bought a VGAto DVI-D adapter and everything plugged in snuggly. All pins and bar appear a match.
But, it won't work. This is what is showing
NVIDIA nForce Serial ATA Controller HP RC Mirror Driver [Display adapter]
NVIDIA GeForce 9100 [Display adapter]
Acer P241W [Monitor] (24.0"vis, s/n LB4040014320, March 2008)the one working monitor....
After hours with the 800 support and hours of reversing the two Acer monitors, the DVI-D port is simply dead. Anything plugged in to the VGA works fine, anything and any combination plugged into the DVI-D and cable switching etc. the 2nd monitor is not even recoginized. The NVIDIA control panel doesn't recognize it. The amber power light just stays that way and nothing ever flashes on the 2nd screen. That is, it is the same as not plugging in at all.
I was less than pleased when 800 tech and supervisor suggested I take it to a repair center. A week old? I have put way too much setup and data transfer into the new HP to go back to the retailer for a replacement.
Techs didn't know, but could there be a DVI-X with the same pins that also fits

Eldric, did you update to the latest video driver from nVidia? It sounds to me like a driver problem. Update and let us know if that solves your problem.

Mac Pro 3.1 (early 2008) lags since I connected a 2nd monitor - HELP!!

Hey guys,
I just bought a 2nd monitor and i have lags every 5 seconds which
last about half a second (feels like 10 or less fps during the lag).
It happens with all kinds of applications. It gets worse with multiple
applications openend at a time. The crazy thing is that it only occurs
when i start to use both monitors at the same time. When i e.g. use
Logic 9.1 and use one monitor everything runs nice and smoothely
but as soon as i move the window slowly to the 2nd monitor i can
see the window lagging while I'm moving it. This is really annoying
because it seems not every input from the mouse/keyboard gets
into the system and its not a smooth workflow at all.
I switched the monitors connections but it didn't help.
Mac Pro (Early 2008) 2.8Ghz 8-core
Snow Leopoard ( 10.6.2 )
6GB RAM (2x2gb kingston, and the usual 2x1gb)
ATI 2600XT and 3 HDD.
1 Monitor 24" LG W2452T running at 1920 x 1200
1 Monitor 22" Samsung Syncmaster 2243BW running at 1680 x 1050
I really hope that you guys can help me out with this one.
What could be the problem? The ATI 2600XT should definately
be able to handle two screens at once with such little graphics
in logic 9 ?!
I want to run Logic 9 and an analyzer software (Spectre from AudiofileEngineering)
at the same time but its not possible with the LAG.
The problem/lags also occur when i sync the monitors.
Would a 2nd graphics card be a solution? But as I said
before its not a graphics demanding application.
Is it a hardware or software problem?
Summary:
- The whole System lags (not just one monitor) when
I start to use both monitors (having application windows on both).
I've got minor lags when using only one display and leave the
2nd one with the desktop wallpaper clean.
I tried:
-using only the 2x1 GB RAM which came with the mac pro
-using only the 2x2 GB Kingston RAM
Thank you in advance for your help guys!
Rick

Hey all,
I wasn't able to fix this yet.
I did everything I can think of. I even tried to wire
one monitor with a VGA cable but it didn't help.
I even have small lags when I am moving the Safari window
between the 2 monitors. Really little lags then but they
definitely are noticeable. I can make a video of that
if that would help someone understanding.
Hope there is someone out there who can help me with this.
Thanks already for any advice!
Cheers,
Rick
Edit: Do you think a new graphics card like the ATI 4870 would
help it? But I really don't want to spend more money just to
have 2 monitors while i have already 2 dvi connections on the
ati 2600XT.
