Connecting a 2nd monitor

I want to buy either a Dell or BenQ 2nd monitor for my mac book pro.. are these monitors compatible??

http://www.apple.com/macbookpro/features.html
On the new MBPs, they have a Mini DisplayPort, which supports VGA, HDMI and DVI outputs. You could get the Apple LED Cinema Display - it might be a little more expensive but it'll definitely work with the new MBPs.
BTW, it'd be handy if you put your system details in the text boxes above the 'post message' button when you put something in this forum...that way we'll know what you're running without you having to keep typing it in all the time.

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.

What cable do I need to connect a 2nd Monitor from the thunderbolt port?

Hi I have got one of the brand new iMac's with thunderbolt ports - what cable do I need to connect my Imac to a 2nd display either VGA or DVI - also is there a budget version about as well as I am sure its going to cost a lot from the apple store

Thanks I understand that I need another cable and have that from when I connected my old PC to the 2nd monitor.
http://store.apple.com/us/product/MB570Z/A?mco=MTY3ODQ5OTY - is this the one I need if going to DVI
I just dont want to waste more money on a cable that says its for an imac to 2nd screen and find it doesnt fit
For info my iMAC is the latest version (27" with the 2 thunderbolt connections and 1 firewire)
Thanks

Connecting a 2nd monitor to my 27" iMac

Hi All, I am looking to buy a 2nd monitor to go with my 27" 2.9 GHZ iMac (purchased May 2013) and wandered if anyone could provide some advice on the best way to connect it through a thunderbolt port and is there anything I must ensure the new monitor has or certain specifiction. i am looking to buy a 27" monitor to sit aside my current one. Thanks in advance for any help.

Unless it's an Apple Thunderbolt display or some other Thunderbolt disply you simply connect a MiniDisplay port to (VGA, DVI or HDMI) depending on what the external display has and connect it up. The System Preferences - Diskplays and setup the setting the way you want. This is the ONLY way it will work. There are hundreds of Youtube videos that show you how, here is one example:

Losing connection to 2nd monitor when iMac sleeps

I have a 2nd monitor connected to my 21" iMac (late 2013) with Mavericks via displayport/thunderbolt port to HDMI. I had the same one with the same link connected to my old 2010 Macbook Pro, and I never saw this.
What happens is when the computer goes to sleep, all of the windows on the second screen move to the iMac, and my Wacom tablet even goes from being mapped to ONLY my second monitor to being only mapped to the iMac!
This is kind of driving me crazy, and I have searched and Googled and just can't find a solution.
Any ideas would be rad. Thanks.

Arrange option missing when a 2nd monitor is connected

I connected a 2nd monitor to my 1.9 pre-Intel iMac g5 but I can only mirror my destop. When go under Display preferences, I am not given the option to arrange the displays.
What am I missing?
~reicko

That is how Apple designed those iMacs. The Intel-based iMacs were the first iMacs to allow extended desktop.
However you may want to take a look at Macworld's "Screen Spanning iMac" article.

MacMini (2011) problem with Thunderbolt display if 2nd monitor is connected via HDMI/DVI adapter

Hi,
iam running a MacMini (2011) 2.3GHz i5 with Mac OS X 10.7.4 16 GB 1333 MHz DDR3 256 GB Samsung SSD.
If i connect a Thunderbolt display only - all is fine.
But if i connect a 2nd monitor ( Samsung S23A700) via HDMI / DVI adapter (original Apple) the major screen (Thunderbolt Display) sometimes
is going black and immidiately back to normal. It looks like that it happens very often if i scroll down with the Apple Magic Mouse.
Any ideas?
Thanks in advance
Thomas

I have exactly the same problem. MacMini Server i7 (mid 2011) Macmini5.3.16Gb ram.
Mini and Thunderbolt no blink-outs.
Mini and Thunderbolt and Dell 23" connected to HDMI-DVI connector, the Thunderbolt display blinks out when system is under stress as in the Develop module of Lightroom 4.
I thought it was a problem with my Thunderbolt display, and since its on a VESA mount, I didn't really want to haul in in to the Apple Store. I decided to be sure it was the dosplay...
I borrowed a MacbookPro i7 and ran it from a clone of my Mini. No problems aster hours of use. (But with only ONE monitor.) That suggested that there was no problem with the Thunderbolt Display.
I decided to run the Mini with only one display. Again no problems. I plugged in the Second monitor to the HDMI port and within 2 minutes I had my first "Blink-Out".
I ran the rest of the day without the second monitor with no problems.
I conclude the mini will not work reliably with two monitors if one is a Thunderbolt.
I was using two Dell Monitors before I got the Thunderbolt Diskplay (for 3 months) without incident.

A 2nd monitor.

I have an iMac(24") and wish to connect a 2nd monitor.... have had this kind of setup at jobs and find it very useful. Is this possible, and I'm considering a 24" Apple monitor. Appears to have 3 cables to hook up and I'm running out of USB connections.

The 24-inch Apple "LED" Cinema Display uses a Mini DisplayPort connector, so you need to have one of the recent Macs that have a Mini DisplayPort. For iMacs, the models introduced March 2009 and the current iMacs have that Mini DisplayPort. The 2008 model and earlier Intel iMacs have a Mini-DVI port; those iMacs will not be able to use the new Apple 24-inch display.
If your iMac has a mini-DVI port, you can use any DVI display, up to 1920x1200 resolution (which is the resolution of your iMac's built-in display). You need this adapter
http://store.apple.com/us/product/M9321G/B
or a third-party equivalent. There are also adapters that go to VGA and HDMI.
If your iMac has a Mini DisplayPort (not Mini-DVI) and you want to use a non-Apple DVI display, this is the adapter
http://store.apple.com/us/product/MB570Z/A
and to use Apple's 24-inch display, you do not need any adapter.
Note: That USB connection is for the built-in USB hub on the Apple display.

Thinkpad T440s freezes with 2nd monitor via dock

Hi there - I have a strange problem with my Thinkpad T440s:
Connecting a 2nd monitor directly (VGA) works like a charm, however putting the Thinkpad into the docking station (with the 2nd monitor connected to the dock) freezes the system. Without the 2nd monitor the dock is working fine. When booting with the 2nd monitor connected to the dock, both screens stay black as soon as the kernel loads.
Is this a known problem / any ideas? Can I somehow help fixing this problem?
I know that I'm not the only one since I have found other people reporting this here: http://thinkpad-forum.de/threads/165520 … -und-Linux
They also provided an xorg.log (http://pastebin.com/Qk7nHVwt) which shows nothing suspicious, I guess...

Same issue with my T440p. Happens with VGA, DP & HDMI (haven't tested DVI) on the dock. Undocking unfreezes it. If X is running the X server freezes and consumes 20% CPU, if none is running a kworker process does that. Even with no monitor attached it will freeze when the builtin monitor wakes up from sleep (again, undocking helps).
Here's a stack trace from the frozen X (^C'd while it was frozen from waking up the display, gdb only reacted again after undocking):

Edit: "Solved" by returning the laptop. This issue plus the loud (and not well-controllable) fan and the lack of support for the fingerprint sensor (different from previous ThinkPad models, it's from Validity Sensors) just aren't worth the trouble.

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.

Connecting a 2nd Palette monitor to iMac

I have an iMac 24" 28Ghz (1Mac,8.1) and want to connect a second palette monitor to the mini DVI port, using a mini DVI to VGA connector.
A search of the forum shows issues with cursor jumping and wrong resolutions.
I really want to run my Adobe CS4 suite with the tabbed palettes on the second monitor to my right.
Is anyone doing this without issues?
Peter

Well given the huge response, I figured I'd just go ahead and warn all the vendors that they could have their stuff back promptly if it didn't work as advertised.
I bought a dead cheap 2-for at OfficeWorks. 2 Philips 160EI TFT 40cm monitors, only A$186 for both. I also got an Apple mini-DVI to VGA adaptor which has dropped in price from Apple's previous rip-off rate to A$25.
Installation was quite straight forward although the monitor looks like a dwarf next to the 24" iMac.
I installed under OSX 10.5.8 and then switched to OSX 10.6.3. Under both it was recognised immediately but defaulted for some reason to a non-native resolution, easily fixed.
I didn't need to *color manage,* that's not what it's for, but both Apple's color calibration and the on monitor controls only screwed it up so I went back to the default settings just playing a little bit with the on monitor contrast and color to try and crisp up the Finder text which still seems too soft. Apple's color calibration lead it to be way too dark. The monitor controls way too light, so factory settings is where it stays.
Visually the monitor is a tad unsharp with a visible vertical banding a little like thin corrugation. Colors are pale, about max 70-80% tint to my eye.
I was able to set separate screen backgrounds, so that I could have a pleasing black & white background to my palettes.
I tested several applications running simultaneously along with movies on both monitors. All work flawlessly so far.
I can now run tutorial DVDs on the 2nd monitor whilst keeping the application to which it refers open on the main monitor. Nice!!
*Testing palettes with Adobe CS4:* They cleverly snap to whichever of the 2nd monitors edges they are dragged to and work perfectly even sensing the real estate available on the monitor. I have set them to snap to the inside (left edge of the 2nd monitor, which is to my right). This means that for the first time the optional sub-palettes pop out to the right in reading order.
All remember their position between re-startups. No sign of flickering or any of the problems reported in the forums. That is in both Leopard and Snow Leopard.
Flicking between fullscreen view using the tab keyboard shortcut and the toolbar options has different results. Sometimes the palettes stay with the main screen in full screen view, sometimes they disappear, I'm trying to work out what combination of actions sets off what.
*Testing palettes with iWork:* They have none of Adobe's smarts but can be stacked a little awkwardly to fit. Awkward because Apple hasn't worked out how to sensibly do this and made them different sizes. However they do remember their sizes (sort of) and positions between restarts.
Pages' Outline/Fullscreen view unfortunately blacks out both monitors. I was hoping I could keep my palettes visible on the 2nd.
Overall I am very happy. I worked with 2 monitors for almost 2 decades until Apple made it both expensive and extremely awkward on several occasions. It feels very liberating to have my full workspace clear again.
OSX is one clumsy design for handling windows, despite/because of all Apple's efforts.
There is no substitute for more/separate screen real estate. So far I am one happy camper.

How to connect an HDMI monitor as 2nd display?

I want to connect an HDMI monitor to my MacBook Pro to use as my second monitor. I need to know what type of cable to use? I use iPhoto and iMovie extensively and it would really help to have a second monitor. Which port on the MacBook would I use?

If your MBpro has a MiniDisplay port or Thunderbolt port then you buy a MiniDisplay port to HDMI adapter and a HDMI cable. (The adapter will plug into the Thunderbolt port).

If you have the new retina model, it has a HDMI port built in.

How do I connect 2nd monitor to 2010 Mac Pro?

Hi all, I'd appreciate some help as I'm a little out of my element.
I have a mid 2010 Mac Pro tower and I'm looking to add a second monitor to it for my video editing.
There is no second monitor port in the back that I'm aware of, just the one for my primary monitor.
Is there a possible way to connect a second monitor to this machine? If it requires adding another video card or something else special, links are appreciated.
Processor 3.2 GHz Quad-Core Intel Xeon
Memory 8 GB 1066 MHz DDR3 ECC
Graphics ATI Radeon HD 5770 1024 MB
Software OS X 10.9.5 (13F34)
Thank you in advance

You don't need another card or USB adapter.
Your current graphics card can run up to three displays. It has one dual-link DVI-I port and two Mini DisplayPorts.
If your new display uses Mini DisplayPort or DisplayPort, you can use a Mini DisplayPort to Mini DisplayPort or DisplayPort cable

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.

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?
Chris

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...
