External Video Display Blackout

I cant find a way of sending a Black signal to the external monitor.
I am using Powerpoint 2004 and I want to work on my project without sending the video signal to the projector (or unplugging the signal cable)
Is there a handy keyboard shortcut I can use to toggle a blackout signal to the projector?

It's probably a small amount of VRAM corruption that's causing it. By sleeping it causes it to be reset and refreshed. Be sure to have your software up to date as new drivers are often included in these updates.

External video display switching

I thought I had sent a mesage to this forum, but it failed to show up. If a duplicate, I apologize.
I have an old X61s running Debian Sid and now want to use it to drive an external projector. However, the Fn+F7 key combination does not cycle between external display, internal display, combination. The internal thinkpad display remains all the time. I assume that without any external device connected, the key combination should cycle through the options. Am I correct? Am I doing something wrong? If not, can I troubleshooft?

Hi Haines,
Welcome to Lenovo Community!
I request you to install Lenovo power manager application and check with Fn+F7 key, this will enable the function key feature. You can switch between the monitors by pressing Windows+P keys, but you should have installed the graphic driver to work with this option.
Below is the link to enter the downloads page and install Wifi driver and check accordingly, please click on "Select Product" then in "QUICK PATH" enter the MTM no. select the exact model.

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!

External preview display via. Mini-DVI to video adapter QUESTION

Hello, I have been browsing this forum for a while, and this is my first question.
I have a Macbook Core2duo running Final Cut Pro. I purchased a Mini-DVI to S-video/composite video adapter.
I cannot get my work to preview on this external monitor. I would like to view the canvas on the monitor while working. I had this setup at school on a G5, but I cannot get it to work on my macbook. The only way apple suggests doing this is by setting up a camera via. firewire and then run from the camera to the NTSC video display (television). I would just like to do it via. mini-dvi to my television for previewing.
Any help is greatly appreciated. Thank you,
Morgan Bressler

From what I've been told, using the computer's video output isn't outputting a true NTSC picture. I was told when talking about how the Macbook Pros dropped the S-vdieo port that I shouldn't use that anyways, but rather to go the firewire route. THat was actually converts the video source to true NTSC instead of taking a computer output to a TV. While I have no doubt that it works, I'm willing to bet that you'll see a noticeable difference between the G5 S-video and your MB using firewire. Most consumer camcorders from the past several years do digital (firewire) to analogue (NTSC) conversion, so you probably don't even need a new box.

Can I have an external video source run in a window instead of using the full display?

I'm aware that the 27" iMac models are capable of accepting external video sources, but I'm wondering if it's possible to have an external video source run in a window on the desktop, rather then use the full display. Does anyone know if there's any software I can download to allow this, or will I have to purchase a special capture device?

hat I DON'T WANT TO OPEN the window application FROM the Labview VI BUT IN the Labview VI. I think it's possible to do that and to do communicate the OpenGL application with the Labview Interface using an ActiveX but I don't know how. Can someone help me ?The desired behavior you desribed may not be possible with that application. In general LabVIEW does not offer a window object that other standalone applications can run it. The closest thing is the ActiveX container. If the programmers for your application created an activeX control of your program and they provided documentation, it should be pretty easy to incorperate the app and labview into one window. I recommend contacting the manufacuturer of the app to see if they have an activeX control version of the app.

Portrait Display 640 x 870 75 hz on External Video Port?

Any way to force external video port into 640 x 870 @ 75 hz mode? I've got an old Apple M1030 monochrome display and a suitable cable adapter. My Pismo Powerbook recognizes that the M1030 as external display when connected, but doesn't seem to offer 640 x 870 as an option in mirror display mode. (There's clearly ouput, but display can't sync to it.) Anyway to force 640 x 870 mode? Some command line option, or even program interface? Anyway to turn off mirror display and keep the external setting window onto my Powerbook's display?Other ideas?
Thanks,
Seth

Can't get Mac OS 10.3.9 to accept SwitchRes setting 640x870. SwitchRes knows this setting, and, I can create a "custom" 640x870. But, it seems Mac OS 10.3.9 will not allow such a setting to be installed. (Reviewed by email with author of SwitchRes, Stephane Madrau.) There may be some "sanity check" in the OS which won't accept this aspect ratio. For what it's worth, I use video timings from Mac IIci manual p.51 (PDF p.59) http://developer.apple.com/documentation/Hardware/DeveloperNotes/Macintosh_CPUs-68K_Desktop/MacIIci.pdf Anyone know if 10.4.x would tolerate such a setting?

No external video playback on 24' LED Display

Hi,
I'm having a problem using my 24' LED mini display port Cinema Display as my external video monitor with my macbook. I have trashed prefs, switched from all to single frames and back. Refreshed connections. Started new projects. etc.... All I get is the frame that I pause on from the viewer on the display but no actual playback except scrubbing. I'm using Final Cut (6) Studio 2. I have started from scratch many times and no success. Any suggestions?
Thanks in advance!

Sorry but I'm not trying to bump this but I can't find the solution anywhere. Motion and Livetype uses the second display in sync with no problems. FCP6 which once worked fine under this setup now only allows either the viewer to play or the monitor to play playback. They will not play together as they once did. Is anyone else with this setup having the same issue?
Macbook Pro (late 2008)
Final Cut Studio 2
24' LED Display (as external video monitor)
When single frame is selected viewer plays back only, all frames LED display playback only. I'm almost certain this is due to an update because this worked just yesterday and nothing has changed except the OS update. Like I said motion and the other studio programs use the LED display for synced playback from the viewer just fine. FCP is the only problem. Its not the end of the world and I can switch back and forth or break out my AJA IO but I liked the way it worked. Anyone?

I'm use two screens, Firefox 4 is not displaying correctlying on my second screen. How do I fix this? (I have Windows 7, 64 bit, and using an external video card)

It only happens on the screen I'm using the external video card. I'm assuming its a bug.

I think this is related to other posts, the solution at the moment seems to be to disable hard acceleration.

MacBook Pro 13 + LG W2240T - No external monitor display

Hi all. Have a brand new MacBook Pro 13 and LG W2240T connected with the MiniDisplay-->DVI-D adaptor. When I plug in the adaptor the screen on the Macbook flashes, the LG immediately says "DVI-D Power Save Mode" and then goes black. When I click "Detect Displays" it shows that no external monitor is attached. If I unplug the connector the MacBook display flashes. I think the Macbook is seeing something but it isnt sending a signal to the display. If I unplug the cable from the monitor I get a general "check signal" message floating around the screen. Dont think it is a problem with the screen. I dont want to have to shell out another $30 for a MiniDisplay -->VGA adaptor and use an analogue signal with the beautiful new digital display.
Any hints or suggestions appreciated.

I'm having the same trouble. Actually, my Macbook detects the monitor but no signal is reaching it. I am using a DVI-A cable from what I can tell. There appears to be a DVI-D or DVI-2 type cable available as well.
The connection is as follows:
Macbook Mini Display Video output to (Mini Display/DVI adaptor) then the DVI-A cable to a DVI/VGA adapptor (sub-D monitor connector) to the external video monitor input. I can see a "No Signal" message when I use a "picture in picture" function on the external monitor screen but get just a black screen with the monitor set to full screen VGA input.
So do we think the trouble is the type of DVI cable or is there some further Mac secret handshake that I need to prompt the output from the Macbook. The odd thing (to me anyway) is that the Macbook recognizes the monitor by its brand and model number after doing a "Discover Monitors" search. But the signal does not reach the monitor and I don't know if there is anything else I need to do or if it just doesn't work.
Further info is that I just tried disconnecting the DVI input, which I use as the main video connection to my monitor and I get the stock "arora" screen image from the Macbook but that's not what is currently being viewed on the Macbook screen. So perhaps I can just set the Macbook to "Mirror" the displays and use the DVI connector. The trouble with that is that the DVI connector is occupied on both of my external monitors. I haven't even tried the other monitor yet as it's a plasma TV in another location.
What do you guys and gals think is the best and most cost effective fix here? I just want to be able to output signal from my Macbook onto the larger displays so that I can work more comfortably.

Can I connect an external video camera to a mac book pro for viewing live video so I don't have to use the little screen on the camera?

• Only if your video camera supports it. Depending on how your camera works, you may need to add preview software to your Mac to use this feature.
• Alternatively, your camera may also be able to record directly into your Mac while you are monitoring the Mac's display.
• If you are using a consumer camcorder that supports HDMI monitoring, a small HDTV might be an simpler solution than your Mac. For an example of how this is done, see http://youtu.be/GVpSkZD6qE4.
• The retailer who sold you your video camera may have other suggestions.
• If you need more professional results, an external preview monitor will offer more capability on compatible cameras.

hope someone can help!

May have something to do with whether or not the URL can be reached while building your widget. I've got a video on the web. When I enter the URL into the field for the video object and click to another field, the URL is replaced with some text indicating that it is accessing the video then updates itself to displaying just the name of the video file.
It shows just fine in preview and I can see the full path to the video when I export the widget so it should work for you.
Is the video accessible from your Mac while you're laying out your widget?

Brand new macbook pro 15" when connected to external LCD display in high resolution ,flickers often

Hi,
I have brand new macbook pro 15" with retina display.
I have connected external LCD display (Samsung B2230) using Apple VGA adaptor & thunderbolt port. But LCD display flickers quite oftenly. I read community blogs where many macbook pro users like me are facing similiar issue.
There is no problem with LCD display as it works fine with Lenova laptops.
Can anybody please provide me the solution to this problem.?
Regards,
Sam

Problem With External Video

I am currently running Final Cut Pro 5.1.2 on OS X 10.4.8. I am having some serious issues trying to get Final Cut to display the timelines video out to my TV. I have my Canon GL2 connected via FireWire, and set it up so the DV input plays as the audio/video. It then goes out to the TV via some standard RCA jacks. I have done this before, no problem.
The settings are as follows:
External Video: All Frames
Video Playback: Apple FireWire NTSC (720x480)
Audio Playback: Audio Follows Video
Sequence Preset: DV NTSC 48 kHz
Capture Preset: DV NTSC 48 kHz
Device Control Preset: FireWire NTSC Basic
If I turn the camera off, the output shows it as 'missing'. I can import using the camera so I know its connected correctly with the FireWire. I can see playback on the TV if I watch the tape, so I know that too is connected correctly.

Its funny you should reply, I was just looking through my posts, and was reading a response you left months ago when I asked a question, then I came back to this post and there you were again! Thanks, I fiddled with the camera for a bit and finally did something to get it to show up. Marked as solved.

Scrubbing problems with external video turned on

I recently upgraded to Tiger and using FCP vers 4.5. When my external video is on and viewing on my NTSC monitor, I have a very irritating problem. Whenever I use the keyboard to play in reverse or scrub by holding down the J and K keys at the same time for slow play, the image stutters and drops frames. Also, the Viewer or Canvas display will also periodically black out for a second or two. When I scrub with the mouse, I don't see this problem. It's only when using the keyboard.
When I turn off external video, everything is fine. I've never had this problem in the past with my system. The only thing that's changed is Tiger and Quicktime 7 Pro. I have done all the upgrades and threw away all FCP preference files.
I'm stumped. Anyone else having the same problem?
By the way, video plays fine when in external video mode. Laid off a project last night, no issues or dropped frames.

Oh my goodness I'm having the same problem! Recently I upgraded to Quicktime 7.0.3 but did some Security Updates as well and thought I was up the creek. I'm on FCP 4.5, OS X 10.3.9 and noticed the same backwards stuttering. Thank you so much for putting your solution on there, I will try it first thing when I get to work tomorrow!

External Video Monitor with iMac possible.

Dear friends,
recently i have bought one imac 21.5" mid 2010 model. i am a film maker. i make TVC s, corporate docu, docu and short films. previously i worked hiring differnt post production studios but with growing volume of work i there was need for a personal edit setup. i have FC Studio 7 installed in my imav. i wanted to connect one external video monitor to facilitate the edit work flow. 1st i bought and connected a mini dp to vga adaptor and connected my 6 series samsung lcd tv with it. but the result was not satisfactory. now the lcd tv have become the second monitor and the system was working as dual monitor system. i wanted 1 video monitor as we get in pro studios. then i bought 1 mini dp to HDMI adapotor and connected it with the lcd tv throgh HDMI cable. fantastic. system took it automatically. Now i opened FCP, set a/v display to full screen, audio out to HDMI then view>external video>full frame. and u are through. now yuo can see the time line output in the LCD tv with sync audio. cheers. any better way to calibrate the second monitor?

Thanks a lot for your help.
If i consider an old model, maybe one with a DisplayPort input (late 2009 or mid 2010 iMac), is there a chance to connect the card with the DP input with a simple cable, or to verify the compatibility? The card has a DP output but many articles say that screen flickering or blue screen is the result...

Andrea
