How to disable external display (s-video adapter)

My problem is this:
I have the new iMac in my office and I have my widescreen TV (CRT non-HDTV) on the other side of the wall in the living room. I recently purchased the Apple video adapter so I could run a s-video cable through the wall to my TV. I got it to work fine but how do I disable it? If I have mirroring on (only way to use Front Row) my iMac screen resolution drops obviously but I can't turn native screen resolution back on without either a) turn off mirroring b) remove video adapter.
Surely there is a better way to do this?

I'm not a hundred percent sure this will work for you since I've never used svideo out on my mac before, but if it works similar to dvi out, then do the following:
1. Set you tv up as extended desktop rather than mirror. This will allow you to set different resolutions on the internal and external monitors.
2. When you want to use the TV for front row, drag the Menu bar from the internal monitor to the external monitor in the monitors system pref. This will make your tv the controlling monitor and front row will play on it.
3. When you finish with front row, drag the menu bar back to the internal monitor.
Again, this works when I have my dvi cable connected to my tv, I'm not sure if a svideo output is treated the same way, though I would think it should be.

How to disable external VGA and also enable onboard VGA

hello,

cpu corei5 ivybridge
mis zh77A GA43
vga hd7770 msi
i want to know, how to disable external VGA and also enable onboard VGA ??
and
i want to ask too, if i disable external VGA In MB, it is my external VGA still consumption power? or i must unplug my external VGA ?
how much different power consumption between external VGA and onboard VGA on idle time?
because my computer each night be used for download, i want to save power as i can...
also there is a eco mode? i want to know about eco mode, how much power can be save under eco mode? on idle time computer
sorry my bad english

Well remove the HD7770 and is disabled and doesn't consume any power. You can't enable or disable it the discrete vga when pc is in use. That board does also not support Virtu.
The possible power saving beacuse of eco mode depends on the individual systems. There is no general value. Just try it.

How disable external display

How can i disable my external display on my Imac? I use the second output for my ntsc TV, but sometimes i dont use it. If its connected, sometime apps put windows on the second display and its annoying. How can I s/w disable the external display?

Joe,
The Mac "remembers" where windows are, and usually will not move them back if you disconnect your external display.
Generally what I do if I launch and app and can't see its window (because its on the non-existent external display) is click the "Window" menu, then click "Zoom". This usually brings it back to the main display.

Satellite L500 - How to show external display after closing lid?

Hi,
i`m using the Satellite L500-120 Notebook, and before installing Windows 7 the laptop had a very comfortable function, when i applied an external display.
When i closed the lid of my notebook, the desktop was shown on my external display (with the native resolution of the external display), so i didn`t have to
switch anything at the Control Panel. In Windows 7, i`m missing this function. I already tried to use the Control Panel, but there are no settings, which fits
with the earlier ones. I can duplicate the display, in order to see my desktop screen at my external display, but with the notebook resolution of 1366 x 768.
If i extend the displays, then there is only the background image at the external display, but this time with the native resolution.
So my question is, how to conifgure Windows to recognize that i closed the lid, and that the desktop screen has to be shown on my external display?
Or do i have to install one of the Toshiba applications, which i had before, that realized this function?
Thanks for any help!

Hi
Im not a Windows 7 user because I will wait until it will be released offical but I hope I can help you a little bit:
First of all in Power Management you can choose the action what happens if you close the Lid (e. g. sleep, turn off, etc.). This action should be disabled because otherwise the notebook will shut down or something else.
Then I think you have to install the display driver for your notebook. You can try the Vista driver because the most of them are work on Windows 7.
Then you should be able to set the correct screen resolution for external monitor.
A working display driver is important for clone or extends monitors so check this!!

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?

How to change external display resolution WITHOUT clicking "CONFIRM"?

I have a somewhat unusual situation. My MacBook laptop is actually now a ModBook (a pen-tablet computer), and as such I no longer have a trackpad attached to it. All of my inputs are via the stylus, tapping directly on the built-in display.
This works perfectly fine, except when I need to give presentations on an LCD projector (which is quite often lately). I like to use the projector as an external monitor, so that I can run the Keynote presentation on it while using my laptop screen as the presenter's display, with the upcoming slide, etc. If the projector doesn't give me an ideal native display option (sometimes, the aspect ratio for the 3 or 4 resolutions available in the Displays drop-down in the menubar turn out to be stretched or squeezed), then I, naturally, have to open the Display System Preferences and try out different resolutions.
The problem is, since my stylus only interacts by clicking directly on the built-in-display, I have no way of moving the cursor over to the external display when the dialog box with the "Click here to confirm change/You have 15 seconds..." message appears. So I can never click it ... so I can never confirm the new settings.
The workarounds I've used so far are:
- Mirror displays (not ideal, as I need the presenter preview of the next slide)
- borrow a mouse from someone (usually from a Windows desktop, frankly) and plug that in to briefly mouse over and click the confirm button
I'd love to find a software workaround that allows me to NOT mirror displays and also doesn't require me to carry around a mouse all the time (my laptop bag is already overstuffed...).
Thanks.

How to change the display resolution of APEX ??APEX doesn't have a display resolution. "Display resolution" is an attribute of the device and user agent software used to view the APEX page.
What do you mean by "the display resolution of APEX"?
In other word, if an end user sees large elements on a pageWhat "large elements"?
then he/she zooms it outHow?
"Zooms" what—the entire page or a single "large element"?
How can I set a proper ZOOM for my app by default ...Meaning what?

New macbook pro 15" won't detect external display using vga adapter

Hi there
I've tried multiple monitors and connectors but i can't get my mac to detect an external display. it responds as if nothing is connected. I'm fully up to date software-wise.
any ideas?
thanks for any help!!

Hi, I'm having the same problem, tried to connect both a Viewsonic and a Hanspree. Was happy to find your response here, but I just got the Moshi adapter with the macbook pro so it seems silly it would have gone bad. :/
I suppose I'll take it into the Apple Store and see what they say. Thanks!

How to connect external display to iMac

which port do I use to connect external display to my iMac ?

Welcome to Apple Support Communities
Depending on the iMac you have, you have different ports: Mini-DVI, Mini DisplayPort or Thunderbolt. Mini DisplayPort is available in 2009 and newer iMacs, and Thunderbolt is available in the Mid 2011 and Late 2012 iMac.
You have to use one of those ports to connect an external display. You will probably have to look for an adapter, depending on the port the external screen has got

How to disable 'select display' on screen sharing?

One improvement in Lion is Screen Sharings 'asking' of the current logged in user as to whether or not it is ok to share the screen. While I understand the need for this in a multi-user environment, this is a unnecessary level of feature for most home users. In fact, it's been a total pain and I'd like to know how to disable it. Trying to remote support parents has become virtually impossible as they are unsure as to what it means to allow screen sharing when I attempt to connect.
Anyone know how to disable this feaute and let Screen Sharing work as it did pre-lion?

Apple menu > System Preferences > Sharing > Screen Sharing > Allow access for: account you want to log into
Connect as that user.

External display - how to disable internal display or to move dock

Hi,
I'm using my MacBookPro with my external monitor. Since my external 24" Monitor is big enough, I don't want to use my integrate monitor. At least I'd like to move the dock as well as the top bar to the external monitor, because my MacBookPro is not in front of me.
Any ideas?

You have several options.
First, and simplest, is just video mirroring, where the Mac sends the same signal to both the internal LCD and the external monitor. Since both screens are showing the same image, it doesn't matter which one you consider 'primary' - they both are.
Secondly you can designate which screen is primary using the Displays Preferences. Under the 'Arrangement' tab you can set the relative position of each screen (e.g. LCD to the left/right of the monitor) by dragging the screens around. You'll also notice that one screen has a mini menu-bar visible. This denotes the 'primary' screen that handles the menu bar and dock. Dragging this menu bar to the other monitor will change the primary screen to that monitor and achieve what you want.

How to disable intergrated Display

As subject above, i want to plug my old G force 4 into my K8M Neo-v AGP slot. When i did, my samsung 710N black out but the power LED still blinking. When i unplug the VGA cable, my monitor show 'no signal'. i know i should disable intergrated Disaply at Bios but i don't know under what Title. Pls help. P/s i never update my Bios.

Have you tried plugging the monitor into the onboard video with the GF4 in the computer? if it works then it's just a simple operation of changing the 'Init display first' option (or similar) in the bios to "AGP" or "AGP slot"
There is also another problem I have heard of, unlikely but it is possible - some GF4's don't like monitors with a Pin 9 on their signal plug. this pin doesn't actually connect to anything, but if it's physically there, it can cause problems, so on most monitors it is never put there to begin with.
If you can't get the monitor to work with the GF4 even when it's set to first display, and you have a pin 9, try pulling it out.

How to disable/uncheck IPv6 in network adapter properties

Hi,
I need to programmtically disable/uncheck IPv6 during all Windows 7 deployments. Does anyone know where to find this in the registry or is there a Microsoft utility you can can use to achieve this?
This is what I'm talking about:
Open Network and Sharing Center
Click Change adapter settings in the upper left
Right click Local Area Connection
Choose Properties
On the networking tab, look for Internet Protocol Version 6 (TCP/IPv6)
I need to uncheck the checkbox on that line item
Thanks a lot for your help!
Rob

Microsoft has a command line program nvspbind (http://archive.msdn.microsoft.com/nvspbind), that can disable ipv6 on a specific interface. It seems to be identical to unchecking the
IPv6 box in adapter settings dialog. You can launch this program from a script or your program.
The command line arguments to disable IPv6 on a particular interface is:
nvspbind -d {GUID} ms_tcpip6
