Using Second Display

I am in the process of buying a flat panel LCD. It has a PC input. I was curious if it anybody knew if it was possible to use the flat panel as a secondary monitor. The trick is I'd like to use it wirelessly. Something as simple as sticking in a Wireless USB hub, and the Mac detecting it as a secondary monitor. (too simple for even the mac? =] )

Hello,
The +iMac (Flat Panel)+ can use a second display via the MiniVGA connector but can only mirror the image of the internal display so if you have the 15" model you can only use a 1024x768 display. I don't think any of the USB/VGA adaptors are Mac compatible (or at least that I've seen).

Using second display as main display

After installing mountain lion I can not figure out how to use my second display as the default, or what use to be #1 monitor. Meaning the second display would have the dock and toolbar on the top.

I haven't tried this myself on ML, but usually under older operating systems, you can in the Arrange mode in Apple menu -> System Preferences -> Displays, just drag the white bar on the top of the representative rectangle of the one display to the other, and that adjusts which display is the primary.

Using second display via eMac's mini-DVI to VGA adaptor

Hi,
I've got a 19inch widescreen display from Acer, model no. AL1916W. I have apple's mini-DVI to VGA adaptor and have connected the second display to the point where it mirrors the screen on my eMac, however I don't want it to do this.
What I had intended is that the second display would act as an extension of my eMacs screen, so I can drag windows across for extra space. Is this possible with the eMac?
Put more specifically, I want to be able to put logic's main (arrange) window on the Acer widescreen, and then have whatever else on the eMacs screen? Is there a workaround to do this?
help much appreciated,
Toby

Hi,
It's funny you should send me that link, I actually found that a couple of hours after posting this and tried it. It worked perfectly, I now have the widescreen running in it's native resolution and working as a separate screen which I can drag stuff in and out of. I came back on here to mark the question as 'answered' but I couldn't find how.
thanks for your help,
Toby

How to use second display as primary display?

Mac (20-inch Late 2006) 10.4 seems to have burned out its LCD screen (at least I think it did). The screen is dark but not 100% black. In any case, I cannot see anything on the screen.
I plugged in a second monitor and the second monitor shows my background image, but in extended desktop mode.
Is there a way to make it the primary monitor when I can't see any menu or dock items? I guess that is called mirror?
I have tried F7 and cmd-F1 and resetting the PRAM did not help.

Thanks to both posters for suggestions. Resetting the PRAM didn't work. Turning on voice over was useful and I was able to login with some guess work (of course, I had to remember which of 5 accounts I was defaulted to, but that only took a few tries). Once logged in, the dock was on attached monitor because I keep it on the right side. Not sure what would have happened if I had it at the bottom. Of course all windows opened on the imac monitor so I had to remember that I could get the system preferences to show me its options by command clicking on the doc icon. From there it was relatively easy to turn mirroring on once I could see the dialog box. Shutting down and rebooting into other accounts has kept the mirroring on. Now the only down side is that instead of looking at an imac, I have to look a few inches in front of it at an ugly Dell monitor. But at least I can keep the folks who use this computer working! thanks again.

I want to use my apple TV as a second monitor not a mirrored one, in other words, I want to use my TV as a second screen not a copy of my first screen,other people have asked this question but have been given mirroring answers. I want a second display.

I want to use my apple TV as a second monitor not a mirrored one, in other words, I want to use my TV as a second screen not a copy of my first screen,other people have asked this question but have been given mirroring answers so I am spelling it out here very specifically. I want a second display. This should be possible and would be awesome. Anyone know how to do this?

Nevermind I just installed it to try it and it's awesome, so happy right now, Thanks. All the things I had read about it on third party sites led me to believe it could not do extended desk tops, thanks for your help!

G5 Second Display using the GeForce FX 5200 - Non-Standard

I want to attach a second display to my machine, but the second plug on the card is a non-standard DVI-type connector. It looks like this:
x x x x x x x x x x X X
x x x x x x x x x x -----
x x x x x x x x x x X X
...with 10 rows of 3 as opposed to 8.
I have had trouble finding an adapter to use to convert this to VGA (which is what I meed to connect my second monitor). I've searched the Apple Store online to no avail, as well as Google. Perhaps I've had no luck because I don't know the name of this part.
Any help is much appreciated!

Hello! Does the port look like the one below? If so you'll need an adapter. Tom
Actually, HERE is the page i was looking for that shows and describes all dvi connections.

Can I use a Sony all-in-one PC/TV as a second display for the G5?

I'm trying to build a pro music system out of my G5, which means that it should only have music software on it. I have an aluminum 20" display hooked up to my Radeon x800T video card, which has one DVI and one ADC jack on it. A pro music rig needs two 20" displays, at least, to display all the mixers, processors, instruments, etc. I have to use a PC for my financial stuff and need a new one. The new Sony Vaio VGC-VA 11G is their version of the i-Mac G5, it's all-in-one plus it is a 20" LCD TV with S-video and composite video in, not VGA in. If I get an ADC-to-VGA adaptor and hook that up to a VGA-to-S/video & composite adapter (all on ebay!), can I plug the output of the G5 to one of the video ins on the Sony Vaio and then use the Sony Vaio's TV as the second display (not simply mirroring the Apple display)? I guess it would be the same as using an LCD TV as a second, non-mirroring display. If it works, it's going to be cool!

By reading the user's manual, it appears that is possible. Download the User Manual from this link:
http://support.lenovo.com/us/en/products/desktops-and-all-in-ones/ideacentre-b-series-all-in-ones/id...
Chapter 1.1
With the computer off, turn on the monitor, button farthest to the right.
Next button to the left of the on/off button, controls the input. Cycle it until you see HDMI in.
I don't have B520, but I have an A310 and it works the same. I hope that works for you.
Good luck!

Using my tv as a second display?

I have a few questions about adding a second display to my MBP.
1. When adding this new display, will it display the exact same thing as on my MB or will it be an additional space?
2. I decided to do this in the first place because I found a "monster" branded cable in officemax on a steal 80%off. It is branded for the Zune though. I noticed however on the display adapters for the MBP, there were similar inputs. It isn't working though.
3.When I plug the wire into the earphone jack, audio comes through my tv. The output next to it (on the left) I assumed was the display output and doesn't work. Is this the correct output or am I pushing my luck and should buy the proper cable?

2. To connect a TV use the Apple DVI to TV adapter which has a S-Video or composite output suitable for a TV. Using a Monster Zune cable , small wonder it didn't work.
The other "output" is actually an audio line input. The video output is actually on the other side and is a DVI port to be used with the above adapter.
I presume this Zune thing has a plug like the size for a iPod or similar small earphone size with three conductors on it? Might work in an iPod but connecting it to a line in will never work. In this case the Zune-iness is not the problem vs. using the completely wrong connector.

How do i set up a second display for my iMac desktop? I want to use both displays at the same time.

how do i set up a second display for my iMac desktop? I want to use both displays at the same time. My iMac is the 24" Late 2006 model. I recall that there is a cord for plugging in a second monitor, but I want to make sure that i can use both monitors side-by-side at the same time. thank you.

If the Display supports DVI, then you will need a > Mini-DVI to DVI Adapter and a DVI cable.
If the Display only supports VGA, then you wiil need a > Mini DVI to VGA Adapter and a VGA cable.
Noting that the (digital) DVI is far better than the (analog) VGA connection.

How to use the second display for installation OS in my vertical lines iMac

My 17" iMac display is full of vertical lines, it is unuseable. Does anyone know how to use the second display for Mac OS X or disable the first display for installation Mac OS x ?

Go to: *System Preferences > Displays* and select the Arrangement tab, then relocate your Menu bar by dragging it to the other display.
Unfortunately there is no Hardware or Software switch to turn off the iMac's Internal Display.

Hi, I use BootCamp for my windows 7, I have a Macbook Pro 2012, and I want to use a second display, is this possible with my Mac using Windows?

I just dont see a port usable for a second screen. I want to hook it up to my TV to view photos and movies. What can I do?

What do you mean you don't see a port? Does your computer have a HDMI or a ThunderBolt/Mini Display port? You can use these to add a second display. Which one you use depends on what input ports your tv has.

Using a second display

I just purchased a 15" Powerbook and have attached a 23" Cinema Display. I have several questions:
Is it possible to turn off the second display without physically detaching it from the PB?
Is it possible to turn off the PB screen and just use the second display? (I know about getting a second keyboard and keeping the PB closed.)
When I have the two displays in "mirror" mode, I am not getting a full screen on the second display when i use the highest resolution on the second display. Is there a way to correct this and still maintain the highest resolution on the second display?
Thank you very much.

Hi cerett --
I have to preface my responses by saying I don't have a second display attached to my PowerBook. That said, I think I can answer the first two of your three questions. Here goes:
• Is it possible to turn off the second display without physically detaching it from the PB?
I think your 23" ACD has a power button, right? If so, why can't you just power down the ACD if you want to turn it off without physically detaching it from the PB.
Alternatively, and this also goes to my answer to your second question, you could turn down the brightness to the point where the screen is totally dark. Now, this doesn't seem like an ideal solution by any means, because you'd still have power running to the ACD for no reason, but it would seem to accomplish what you want anyway.
• Is it possible to turn off the PB screen and just use the second display? (I know about getting a second keyboard and keeping the PB closed.)
You write that you already know how to use your PowerBook with the display closed. See: http://docs.info.apple.com/article.html?artnum=86286 So, it sounds like you would like to leave your PB open, but just not have the display on. If so, it seems to me you could just decrease the brightness (using the F1 key or, of course, System Preferences > Displays > Display) to the maximum extent possible so that they display goes totally dark. May not be an ideal option (see above analysis), but it would seem that it should work for you.
Sorry, but I can't help with your third question. I'm not sure, but you might increase your chances of getting the information you need, if you reposted that third question in the Apple Cinema Displays forum, here -- http://discussions.apple.com/forum.jspa?forumID=981 -- as the answer to this question may have more to do with the characteristics of the ACD than of the PB. I'd wait to see if someone comes along here first, and, if not, then repost there.
Good luck.

Using a PC laptop as a second display?

Can anyone tell me a way of connecting up an iMac to a PC laptop so that the laptop acts as a second display? I'm running audio software and need to switch between edit windows all the time. I know you can get mini DVI to RGA adaptors, but im not sure if it'll work?!
iMac Intel 2.33GHz Mac OS X (10.4.8)

Yeah, it works fine. It's just that there is two main windows I have to use, and having the laptop as a second display would mean I could save time switching between them instead of messing about on one screen.
