Connecting external monitor or tv

Hello,
I've got a MacBook Pro Retina 15' and i want to connect 2 external screens to it.
I am already using the HDMI port to connect to my tv to use that as the first external monitor.
I'm thinking of getting a second one for my desk but i can't decide if i should get one of the 2 following options:
Option 1:
Getting a second TV + Displayport to HDMI adapter
Option 2:
Getting a computer monitor + Displayport to DVI (or VGA) adapter
Aside from the size of the screen (tv can be bigger), is there an argument to get a monitor over a tv, and the other way around?
What should i do?
Thanks in advance

How connect External monitor to iMac?

How connect External monitor to iMac?

How to do that depends on the iMac variant you have. iMacs have been in continuous production since 1998 in four broad families that are not 100 percent alike in behavior.
Please look at the iMac images and descriptions in the links on this site:
http://www.everymac.com/systems/apple/imac/index-imac.html
and tell us what variant you believe you have.
iMacs from the first through third-generations (G3, G4, and G5 processors) that support an external monitor were not set up to do anything other than "mirroring"--you see on the external exactly what is on the built-in display.
Your description sounds like you have a newer iMac than this forum covers because, starting with the Intel iMacs in 2006, external monitors were allowed to do both mirroring and "extended desktop." The latter is what I believe you are seeing.
Try this first: press the F7 key. On many Macs capable fo using external monitors, this was a shortcut to toggle between mirrored and extended display. If your keyboard has an "fn" modifier key, you may need to press that to get the F7 key to work.
If you have an intel-powered iMac I can ask the Hosts to move you to that forum, which is much more active than this one which is for pre-2006 iMacs.

Need help connecting external monitor

My brother needs help with connecting an external monitor to his 20" iMac G5. He has the adapter with the standard monitor port, and when plugged in, the monitor duplicates the iMac screen. His question is, how can he set it so that the desktop is extended, instead of duplicated? I, myself, have a MacBook and two months ago I used my adapter to connect a projector, and I remember an option where I could choose between duplicate and extended desktop, and right now I tried to find it on my MacBook and well as my Intel iMac and I can't find the option, and neither can he.
Please help, thanks!

The iMac G5 can only mirror the internal display unless you hack the firmware.
Display options like that only appear when you connect a display which is why you can't see them on the MB at the moment.

Proper way to connect external monitors to macbook pro?

I recently had to have the logic board in my mbp replaced and was wondering if disconnecting an external monitor while computer is on would cause the problem.
Should monitors be connected/disconnected with computer powered down?

If fact, the correct way to connect external displays is to have the MBP on, the external display on and seeking a signal, the external display cable connected to the DVI-to-VGA adapter (if necessary), and then connect to the MBP. So, the last connection is to the MBP, but everything is powered on. That way, the MBP autodetects the display.
Even if you don follow that procedure, connecting/disconnecting a cable from the DVI port would not do anything to your logic board.

HMDI Connected External Monitor only works mirrored

I've got a 27-inch iMac with the 2.93 Ghz Intel i7 (running Mac OS X 10.6.5) connected to a Hannspree HF289H 27.5in external monitor (1920x1200 resolution, connect via Mini Display to HDMI adapter and an HDMI cable). It has worked fine for a few months, but all of sudden the 2nd monitor will just go black. When I restart the computer, the 2nd monitor will flash on and off and resize, but will not show anything once the computer fully comes up. If I go to the monitor settings and choose to "mirror" the display, it comes on and works. Then, if I take it off mirrored, it will work for a matter of minutes to hours, but eventually go black again.
Any thoughts? I've already tried resetting the SMC and restarting with a PRAM reset as mentioned in other posts.

Are you using the method in this Apple article? If you do, it should work.

Connect External Monitor

Sometimes when I have connected an external monitor it has worked, other times not. I am now finding it impossible to get it to work at all. I am connecting to a CRT Monitor through a firewire connection to a Sony FX1 Camera and then by SVHS to the Monitor. The connections all seem fine in that I can capture video through the firewire link and if I play back a tape in the camera it appears on the monitor.
I have Video Out set on Apple Firewire PAL (720x576) and have tried clicking 'Refresh Video Devices'. Easy Setup is set as DV Pal Anamorphic. I have tried trashing preferences and repairing disc permissions. Also re-starting the application and re-starting the computer.

Thanks, I think you may well be right. It occurred to me after making the posting that this is the first time I have used the FX1 in this way. I used an old Panasonic camera before, which my son has borrowed ! It still did not work every time, but it did most of the time. I'll get the Panasonic camera back and try that. I'll also check with Sony about using the FX1.

Connecting external monitor, hard drives

I'm thinking of buying a new iMac for video editing but I don't see how you would connect an external monitor to it. I see USB and Firewire 800 jacks to connect drives, and T-bolt jacks, but no monitor jack. Is it possible?

So the three monitors I have now are useless?
Of course not you can also use what Niel suggested to connect your existing displays. Depending on the connections the displays have you can use a Mini Display port to VGA or DVI or even HDMI. You can find these in an Apple Store or at Apple's online store. I wasn't assuming you already had external displays, I was merely suggesting you could also get the display I provided a link to.

DVI connected external monitor now having mouse troubles

Hi Everyone, I'm new. I recently bought a 27inch imac and a DVI adapter to hook up a second monitor. When the second monitor is plugged in and on everything is ok. When the second monitor is unplugged everything is ok. When the second monitor is pluged in but turned off my mouse skips LOTS. Like it lags a bit then will shoot off to the side of the screen. I tried other mice (apple and microsoft) and different mouse pads/none/paper and no difference. I rang applecare (before I realised it was to do with the monitor) and they told me my mouse was stuffed.... Im convinced the imac gets confused when anothe monitor is connected. Others on mac rumors are having trouble also... Any ideas please?
Cheers

Hello,
I can confirm this problem on my iMac 27" of Mid 2010.
At first in June, when i bought it, i had no problem whatsoever connecting my external Samsung 226bw. It worked like a charm.
After some time, maybe a month of daily use, the iMac refused to wake up the external monitor after waking from sleep mode. Now the problem only got even worse, as it now refuses to power up the external monitor when booting too.
The funny thing is it springs alive after a random period of time. (between 2 to 4 hours)
When the iMac is in its 'Im ignoring your external monitor, Sir' mode, my magic mouse is very jumpy and laggy, like described earlier on in this thread. When the monitor comes alive, the mouse behaves normal.
Now i've been looking into this problem quite some time now on the net, and all i can find are mostly confirmations of people having the same problem.
There are some suggestions here and there on what to do, like resetting nvram or the SMC, deleting windowserver preferences files etc, but none of them seem to solve the issue.
Strange thing is that Apple doesn't move a word about this? At least an acknowledgment of some sort, letting us know they are aware of the problem and maybe try to fix it.

Connecting external monitors

I am trying to connect two external monitors to my macbook (not pro, the white one). I'm using a mini VGI, that connects to a splitter cable. The two monitors show the same image. Is there a way that I can have them not be the same image?

Is the "Mirror Displays" option checked in your settings?

Macmini ( 2 GB RAM) freezes with Leopard when connecting external monitor

Hello,
I am having problems with Leopard when connecting an external monitor.
When the macbook is connected to an external monitor, the system freezes and after some minutes, it system reboots. Otherwise only switch off works.
With Tiger there was no problem. Neither with less than 2 GB (1GB or 1,25GB).
My macbook has 2GB RAM an the external monitor is a Samsung Syncmaster 24" (HW diagnostig tests have been successful: RAM and other components).

Try to resetting the PRAM (Parameter Random Access Memory). Mac OS X: What's stored in PRAM?
I'm using a SyncMaster 940BW and the DVI cable and have no problems like this.

Trouble connecting external monitor to new MacBook

Just today I bought a new MacBook with Leopard, and also bought an external monitor (LG brand). I hooked it up as directed: an adapter from the mini-dvi port to a dvi cable, and the other end of the dvi cable in the back of the monitor. When I turned it on, the monitor was displaying the background picture on my desktop and the dock, but none of the folders and documents on my desktop were showing. Also, the cursor wasn't showing. I tried opening a document in Word, and that did not show up on the monitor. I called the company and they said the monitor should work with a Mac, but that I should get help from Apple because none of them are familiar with Macs and it is probably something I need to change in the display settings on the MacBook. I've never used an external monitor before, and know nothing about this. Do you think I need to return this monitor, or could someone tell me what to try to make it mirror the desktop? Thank you.

Your monitor is working exactly like it is supposed to in extended desktop. Nothing will be on it unless you drag something to it. Open Displays in *System Preferences*. With the external monitor hooked up a control screen for each display will show on the displays. Use Arrangement to drag the external to whichever side you want to have it on. I use mine on the left so my mouse enters the screen in the correct side. You can also use the external in mirrored mode where everything is the same on both monitors. The easy way to switch between mirror and extended is the F7 key.

Can't connect external monitor to Windows 7 bootcamp Macbook Pro 15 - ATI 6770

I recently puchased a Macbook pro 15 in 2012. I have bootcamp set up and am running windows 7 home on the bootcamp partition. When in windows I am unable to use an external monitor or overhead projector. I have updated all of the ATI drivers and have fiddled with screen resolutions and display refresh rates to no avail. I am using a cheapo mini displayport to VGA adapter which I have confirmed works while I am using the mac side of the machine.
Unfortunately I have to use windows while at work and using a projector to display data is essential.
I am out of ideas at this point -- Help - - Please!!

I was hoping some of the multi/monitor people would show up and help you but I guess they missed it.
Have you gone into the Properties of the video drivers (via the Device Manager) and let it Update Driver either through the internet or migrate to the newer Boot Camp video drivers you recently downloaded?
The only other thing I can suggest is to completely delete the video drivers then reinstall them manually either through the Programs and Features control panel or in the Device Manager/ Video drivers and see if it "takes".
Don't forget you do have an Apple Software Updater in Windows also. It updates the Windows support software from Apple. (Boot Camp)
Sorry I can't help more........

Connecting external monitor to G4 at higher resolution than 1024x768

Is this possible? I believe someone told me that there is a way since the graphics card can support higher resolution, just not at the LCD.
I am doing web design and that resolution is becoming cumbersome to work with and my external monitor can go up to 1600x1200.
Thanks.

Yes it is possible, but "at your own risk". Look for "Screen spanning doctor".
If you test it, please report here the maximum resolution you can use in clamshell mode. I am going to buy a monitor and I wasn't able to find such value.
I know I can use 1600x1200, I already did it, but I tried the external monitor as secondary monitor. Could you please test the clamshell mode? can it go over 1600x1200 when the main display is off?
