2nd Display Help

Is it possible if i've got my macbook hooked up to an external display to have the external display as my primary display and then treat the macbook display as the secondary one so the taskbar and dock are on the external. I've searched around but can't find anything on it.

I don't have my Mac with me right now, but have you checked System Preferences>Displays?
If I recall correctly, you should be able to drag the display icons to choose which is the primary display. You do need to have that second display connected.

MacBook 2nd display (mini-DVI-DVI (D)- VGA)?

I am trying to hook up a second display to my MacBook. The problem is that I don't have a mini-DVI to VGA adapter, but I have a mini-DVI to DVI, and a DVI to VGA adapters. So I connected my Apple mini-DVI to DVI, to my DVI to VGA, and then to my 2nd display (NEC LCD1560NX). The notebook's image flips as i normally connect a second display, it auto-detects the 2nd screen and displays its correct name, but I do not get an image on my second display. It set to the right resolution and frequency.
Any suggestions?

go to system preferences -> display-> and mirror the displays, it should work on the second display, but the cons on the macbook is to work on the first display, the built in card may not support the second one, if thats the case i'm sorry i can't help it. you can also try to get a DVI/VGA splitter and see if that work, it works on standard integrated intel VGA models. good luck!

I can't seem to turn off my 2nd display (with no adapter plugged in)

Been looking on the internets for ages about this and not got anywhere, so did a completely fresh install last night.
The problem is that the DVI (2nd display connection) thinks that I have a VGA display connected (i.e. the 2nd display) when I plug in the DVI-VGA adapter to use with a TV that works fine. The 2nd display resets to align itself to the TV connected.
When I disconnect the adapter the Mac resets it display. Back to having this phantom display connected.
I've plugged in the DVI-VGA adapter as well and then carefully removed that and sameroblem.
Having done a fresh install that would mean it's not a software issue, so it has to be a hardware one? Something with the actual connection? Does anyone know of any potential problems as to why this would happen?
I've tried some compressed air. (I've lost the straw so it was straight from the can, spray paint style)
Please help.
Thanks.

Anyone?

Connecting a 2nd display

HI,
I have a Mac Pro, circa Dec 07 (therefore no mini display port) and currently use a 23" cinema display. I want to attach another identical display and assume I can do this via the other (spare) DVI port at the back of the Mac?
However, my main monitor has the firewire and USB cables plugged into the tower which come cabled along with the DVI cable, but when connecting the 2nd display can I just connect the DVI cable into the Mac Pro and not bother with the firewire and USB cable which are bound with it?
Obviously I understand that using the firewire and USB cable from the first display increases my available ports (at the rear of the first display)... but do I really need to connect those with the 2nd display, because I'm running out of ports at the back of the Mac!
Hope that makes sense...
Thanks,
Mark

One thing that's occured to me, somebody might know...
I calibrate my main monitor, so when the second display is either being mirrored, or just an extension of the desktop, I guess the existing calibration is sufficient as the main display calls the shots?
Or am I wrong, should both be calibrated as separate displays prior to using them together?
Thanks to anybody who can help...

2nd display disappears on switching focus to another application

Hi,
I'm running LR5 on Windows. I've got the grid view on my primary display and a second display showing the loupe view.
If the focus moves to another application (i.e. a small notepad window on the primary display) then I can still see LR with its grid view in the background behind notepad on the primary display however the loupe view on the second display disappears and I can see the desktop.
Is it possible to configure LR not to automatically hide the 2nd display when the input foucs moves to a different wiindow? I'd like to be able to continue displaying the image on the 2nd display while I'm doing something else on the primary display.
I've not been able to check but I've a feeling this is new behaviour in 5, I don't think 3 or 4 did this.
Many thanks in advance for your time/help! :-)

No, sorry. I've just checked LR3 for you, and the behaviour's the same.

2nd display not as bright as first display

I have 2 facory video cards installed. They're the same (ATI 5770) each have mini ports and aldo DVI.
When I boot up each day at work, the second display won't go to full brightness. USBs are both plugged in and I do get the brightness control levers on the preferences for both displays. However, the 2nd display (at 100%) is just not as bright as the primary display. Both are the same 27" displays; each on their own dedicated video cards. I would say it is about 20% less bright.
Sometimes if I re-boot or reset SMC and monkey with it, I can get it to boot at 100% brightness but lately it's choosing on it's own to be dimmer. Switching USB ports didn't seem to have any effect. I am assuming it's a hardware issue bc I have reset PRAM, SMC, Disk Repair, trashing preferences, and so I'm a little bummed this expensive 27" LED display can't guage it's full brightness.
Thanks kindly for any input / solutions.

To post a hopefully helpful follow-up.. over past couple of days I got it to hold up its full brightness. To restore the full brightness of the 2nd display I disconnected / reconnected the display cable a few times until I noticed it was suddenly matching the full brightness of the 1st display. Is it the 2nd video card? The display? The G5 hardware/software? Can't say.
But after re-booting overnight, it retained the full brightness. Not sure why this happened/s, could be an isolated issue with something slightly defective?? Regardless, maybe this will help someone where both displays are not at full 100% brightness. Replug them a couple times to see if that tricks it back into action.
Remember, my toggles in the display prefs said both were at 100% yet the 2nd display was clearly 20% darker before I got them back to true 100%.
In the end, these LED displays are truely magnificent (aside from my isolated issue).

2nd Display of macbook

I've read a few things about the subject but never had a clear anwser. I've read that the maximum resolution for the 2nd display of the macbook is 1920X1200. Doesn't help me if I plan to buy a 19'' inches with a maximum of 1440 X 900. I want to use the 19'' to expend my desktop. Will it work properly (without distortion)
If you have any infos about that thank you for your answer

1440x900 is less than the MacBook's maximum resolution of 1920x1200. That means it'll work just fine as a second display at its full resolution. You just can't run a display that's larger than 1920x1200, such as Apple's 30" Cinema Display. But the 23", for example, will work fine, as will anything smaller.

ADC from vid card to a VGA 2nd display, out of stock?

We have an old quicksilver G4 800 mhz tower that a co-worker wants to have a 2nd display attached to. The card has 2 outputs, a VGA and an ADC. About a year ago, I went to our local Apple Reseller (not an apple store) and bought a ADC to VGA adaptor for 30 bucks (for another machine in use). It was by Dr. Bott. There is nothing on their website now. Dr. Bott service stated that Apple had something to do with the discontinued status? Locked down their technology?
Some site show any ADC to VGA adaptor discontinued.
What is up?
Alternatives? Should I just get a new cheap graphics card? or are there ther alternatives. Yes, this is old technology, and we will get new computers, but we will have this machine a few more years...
Thanks for any help
Mac Pro 2.66 Ghz Mac OS X (10.4.7)

Apple did not try to stop others from using ADC. They made it an open standard, but few other manufacturers used it. Formac did make a LCD display with ADC. Most display makers didn't want to make models that would only work with a Mac, even though it would be cheaper (no power supply needed). Other computer makers didn't use it because they would need bigger power supplies (Apple made a CRT with ADC that needed 113 watts), adapters would be needed for most displays, and they would need special graphics cards. Because of lack of demand from other computer makers, no graphics card maker made any ADC cards for non-Apple computers.
Apple dropped AC for several reasons:
Multiple displays were being used more, and there was only one ADC per computer. DVI to ADC adapters are expensive and messy.
They wanted to sell their displays to non-Mac users.
Bigger displays needed more power (30" needs 150 watts)
With their main customer gone, the connector maker dropped the connectors, so adapter makers have no more parts for the adapters. Adapters are now scarce and expensive, but it's not Apple's fault.
There are still a few ADC to VGA adapters for sale:

<http://www.welovemacs.com/mcaadcvga.html>
If the Quicksilver is the earlier (2001) model, such as the dual 800 Mhz, the adapter won't be useful with any of the graphic cards that originally came with it. It will work with 2002 Quicksilvers, such as the single 800MHz.

Using an iMac as a 2nd display for another iMac?

Hi all,
is it possible to use an iMac as a 2nd display for another iMac?
I guess it depends (if at all possible) on the models, right?
Would it be possible with two of the currently available iMac 27" models?
Is it just connecting the two video jacks with a cable? That would mean that the jack is input AND output connector at the same time: the video signal would be output from iMac 1 and serve as input for iMac 2.
Thoughts?
Thanks,
Stefan.

Awesome, David! Thank you! That helped a lot!
Additional question: because running applications on the target-display-mode-iMac keep running: will I be able to connect from the source iMac to the target-mode-iMac via OS X's Share Screen functionality? So that I can still USE the 2nd (target-display-mode) iMac for running applications and accessing them? Or is the iMac in target display mode really just a dumb display? Will ssh'ing to it work?
A little background: programs like Cubase and Logic work really great with two screens. Additionally, some audio plugins really need a lot of CPU power and some of those can actually distribute the number crunching via the LAN to other computers. So my thought is: run Cubase on iMac #1, use iMac #2 as a 2nd screen (will work, thanks to David's reply) AND use iMac #2's CPU, too, to help some Cubase plugins' number crunching. Would that work?
Thanks a lot,
Stefan.

Have iMac mid 2007 using Mavericks . . . will not function with new 2nd display?

Sys Prefs setup with 2nd display using Mavericks . . . the new functions of Mav won't come in with LG display even though same display works with my other Macs. Any like experiences or advise would be more than appreciated? bumdiago

Shawn:
One thing that caused the refresh to stop working is when you have error or bad settings in your report. Expand your upper right control panel or EVDRE area and see if everything is good. For instance, an EVDRE usually gives an error message rather than displaying (EVDRE OK) at upper right.
Also, did your input template refresh the data properly every time after you sent your data? If so, you may convert your input template to a report, and see if that will solve your problem.
Hope my 2 cents helps...

LR5 - Photos in 2nd Display are blurry / don't render completely - intermittent issue

Just upgraded to Lightroom 5, and the performance issues I saw in 4 appear to be gone - which is awesome. I've come up on an issue that I've seen referenced in other posts, but only for LR4. Also, the issue seems to be slightly different than mine. My issue is that when I have the 2nd display running in Loupe mode, the image won't render completely and looks blurry/fuzzy, when in Develop mode on the first screen. However, it's not every time. Sometimes it works fine. Sometimes it takes a few seconds, and then it works. Sometimes, it doesn't ever work. It just sits in a blurry state - not fully rendered. Sometimes if I go to the next photo, and then back, it will then load. Sometimes that doesn't work.
While I did have tons of performance issues in LR4 (including 4.3 and 4.4), this was not something I remember seeing.
I'm running Windows 7 64-bit, i7 2600-K, 24gb RAM, multiple SSDs.
Any help would be appreciated.

I'm having the exact same problem in LR5
Selecting another picture and coming back usually fixes the problem.

Can I rotate 2nd display through 180 degrees on a mac mini?

Hi there,
I was wondering if it's possible to rotate a 2nd display through 180 degrees on the Mac Mini? I don't have one yet but if it's possible I'll probably be looking to get one.
Thanks for your help,
J

Yes;
System Preferences: Display: Rotation = Standard, 90°, 180°, or 270°.

PB thinks 2nd display is hooked up when not

I hook up a 2nd monitor at work to hold my Adobe palettes. However, when I use the PB at home without the 2nd monitor, the computer reads that all of the palettes are open while they are not visible.
I've checked my system preferences to detect a 2nd monitor but it doesn't detect it. Please help as I am unable to complete my work without the 2nd hookup.
One other problem, I've lost the 2nd display in Hurricane Katrina so purchasing another right now is out of the question. Thanks!!

Did you try that while your Adobe application was open? If no, try that.
Next, with it open, try going into display preferences. (You've tried detect displays already, so...) Change the resolution to something smaller, and then back again. - this may force the window into the LCD.
Just a thought, but is your Adobe app. up to date for 10.4 Tiger?

2nd display resolution 1440x900 and cannot be changed!

I have connected a 2nd display to my laptop using Toshiba DynaDock. The monitor is an Acer S200 with native resolution of 1600x900. Monitor is connected to DynaDock by DVI cable. However I cannot get the monitor to display in 1600x900. The maximum available is 1440x900. I am sure that when I first plugged in the monitor using VGA that I could get 1600x900 resolution. At some point this stopped. I really don't know if it has to do with switching to the DVI cable. I am running Windows 8.1. The S70 laptop has a 17" display at 1600x900. I'm also confused by the display adapters. The laptop has an AMD Radeon Graphics adapter. However, it appears that this is not being used. When I right click on laptop display, I get the HD Intel Graphics adapter control. This adapter has no idea that there is another monitor attached. It only controls the built in display. I can access the AMD Radeon Catalyst Control center by right clicking on 2nd display, then click Graphics Properties. This opens the AMD Catalyst Control center. However there is nothing within the CCC that allows me to select a resolution. If I click Screen Resolution from right click on 2nd display, I get a window "Change the appearance of your displays". This shows 2 monitors. #1 is Mobile PC Display, 1600x900, Landscape, Extend these displays. #2 is "No Monitor", 1440x900, Landscape, Extend these displays. If I open the DynaDock Display Link Manager (version 7.7.60366.0) , I see 2. Dynadock U3.0. This opens a set of options. If I click screen resolution, there is a list of available options. The list jumps from 1440x900 to 1600x1200. There is no option for 1600x900. If I click any resolution above 1440x900, the "Input Not Supported" message appears on the monitor. Once again, I want to display my 2nd monitor at 1600x900 resolution, but I cannot figure out how to do that. Please help.

You should try checking for software updates from DisplayLink:

Presenter notes w/o 2nd display?

I often teach where I'm working without a projector or 2nd display. I really like having the presenter display with timer and clock with my speaking notes. Is there a way to use the speaker display even if I'm not presenting any display to my audience?

THanks Gary. Yes this would basically just be using it as electronic notes. I cAn break my notes into many smaller chunks & much larger fonts to help keep my place as my vision is changing on me, and I really want the timer & clock right there. I find myself forgetting to check the time when I first start speaking, or if I'm introduced earlier or later than expected I need to calculate time elapsed/left while still speaking & maintaining my train of thought. Hence absolutely needing the timer instead of simple making my notes be the slideshow itself.
