3 external monitor display

I have 1 monitor plugged into VGA, one into a USB which is an external StarTech graphics card, and I have one in the DisplayPort. I want to have all 3 external monitors on, as well as the main laptop display.
Is this possible?

Thanks for your reply gnunn.
Turn off with
xrandr --output LVDS1 --off
via commandline results in a short flickering where both screens are off and coming back on after one second. The same behaviour as with the Gnome GUI.
xrandr show this:

External Monitor display issue

The external monitor for my mac book pro displays large/wide text when both screens are open. If I shut the laptop, the external monitor display returns to a normal view. I tried going to system preferences, displays and it's either on best for display or in scaled, the maximum 1920 x 1080.
Please advise.

Where is extended display mode? In display screen, the mirrored mode is checked, both displays are in 1920 x 1080, not sure what else I can do here? BTW: it just started happening (all was normal on both screens) until I used laptop at my work and connected it to external screen (school) with VGA adaptor (at home I use a DVI).

I'm in the market for a laptop. Which of Apple's laptops will I best connect 2 external monitors/displays?

I'm in the market for a laptop. Which of Apple's laptops will I best connect 2 external monitors/displays?

I've just bought a Pro Retina. As far as I know this is the only one which will connect 2 external monitors running different programmes ie not cloned.
You use the 2 thunderbolt ports for the DVIs (if they're not Apple monitors)
You need 2 thunderbolt to DVIs. MiniDisplay port to DVI might work too (MIGHT WORK! Not sure yet) and these are a lot cheaper.

MacBook Pro 13 + LG W2240T - No external monitor display

Hi all. Have a brand new MacBook Pro 13 and LG W2240T connected with the MiniDisplay-->DVI-D adaptor. When I plug in the adaptor the screen on the Macbook flashes, the LG immediately says "DVI-D Power Save Mode" and then goes black. When I click "Detect Displays" it shows that no external monitor is attached. If I unplug the connector the MacBook display flashes. I think the Macbook is seeing something but it isnt sending a signal to the display. If I unplug the cable from the monitor I get a general "check signal" message floating around the screen. Dont think it is a problem with the screen. I dont want to have to shell out another $30 for a MiniDisplay -->VGA adaptor and use an analogue signal with the beautiful new digital display.
Any hints or suggestions appreciated.

I'm having the same trouble. Actually, my Macbook detects the monitor but no signal is reaching it. I am using a DVI-A cable from what I can tell. There appears to be a DVI-D or DVI-2 type cable available as well.
The connection is as follows:
Macbook Mini Display Video output to (Mini Display/DVI adaptor) then the DVI-A cable to a DVI/VGA adapptor (sub-D monitor connector) to the external video monitor input. I can see a "No Signal" message when I use a "picture in picture" function on the external monitor screen but get just a black screen with the monitor set to full screen VGA input.
So do we think the trouble is the type of DVI cable or is there some further Mac secret handshake that I need to prompt the output from the Macbook. The odd thing (to me anyway) is that the Macbook recognizes the monitor by its brand and model number after doing a "Discover Monitors" search. But the signal does not reach the monitor and I don't know if there is anything else I need to do or if it just doesn't work.
Further info is that I just tried disconnecting the DVI input, which I use as the main video connection to my monitor and I get the stock "arora" screen image from the Macbook but that's not what is currently being viewed on the Macbook screen. So perhaps I can just set the Macbook to "Mirror" the displays and use the DVI connector. The trouble with that is that the DVI connector is occupied on both of my external monitors. I haven't even tried the other monitor yet as it's a plasma TV in another location.
What do you guys and gals think is the best and most cost effective fix here? I just want to be able to output signal from my Macbook onto the larger displays so that I can work more comfortably.

Use G5 iMac as external monitor/display for Intel iMac?

I have a 24" Intel iMac and a 20" G5 iMac (which is sort of mothballed now).I was wondering if it is possible to use the older iMac as an external monitor, mainly to save the expense of buying a "proper" external display when there seems to be a perfectly usable one sitting there in the G5 iMac.

translate.google.com.
Actually, it didn't translate very well. But the instructions are basically how to wire up an adapter cable. The G5 iMac appears to use standard DVI signals, so you just need to make a DVI cable to plug in to the internal connector. The table between pages 7 and 8 is what you want. If you've used a soldering iron around electronic devices before, that table is pretty much all you need. The picture of the backside on page 9 is neat. Using the ethernet connector hole to route the wiring. Almost looks like it came from the factory that way.

MacBook Pro 2011 Dual External Monitors/Displays.

Is it possible to connect and run two external monitors (non-Apple - with DVI input) from a MacBook Pro 15 or 17". (ie, close the lid on the MBP and have two monitors running). Do you need extra hardware?

needs, as of this date, a thunderbolt display, as you will not be able to daisy chain anything other then thunderbolt displays. So you would get a thunderbolt display and then can use that to connect a second display to it with a dongle of your choice.
But it will work, and is natively supported.
There are alternatives to this like DisplayLink which is used to make a usb hardware be able to connect DVI to usb and usb to your computer.
but they've been having some issues with Lion however it's only with earlier MBP models so you might be good. This would be a cheaper solution.
Google usb to dvi I have the Arkview adapter but they're all the same because they use the same drivers. Again, your best bet is a thunderbolt display or waiting for someone to make an adapter that lets you connect multiple display with minidisplay port/thunderbolt.

Remembering setting on external monitor/display

MacBookPro 2.4GHz 2 duo w/ Leopard:
I use an external monitor (samsung, older) at work; sometimes my computer remembers my display settings (i.e. automatically sets to the correct resolution and arrangement) and sometimes it doesn't. I haven't been able to find a pattern.
Is there any way to make it remember all the time?
Thanks.

T400, External monitor displayed off center.

So I have a Lenovo T400 with the ATI/onboard switchable graphics. When I plug it into my external monitor with the onboard graphics enabled, it displays correctly. When I have it connected with the ati graphics enabled, it displays off center and cuts off the right 1/5 of the screen. If I have my external display at a lower resolution, it works like it's supposed to.
1680x1050
1440x900
I've already tried reinstalling the drivers and adjusting the screen position with the monitor... any other ideas?
BTW this is on Windows 7. Laptop code is 2764-CTO

I hate to bump this, but I'd love some help.
Thanks

T420s: External Monitor displays flashing Multiple Colors (a la Kanye West video) then shuts down

Has anyone seen this? I've had it happen to several T420s models. While connected to a docking station with the lid closed, the external monitors will just display flashing colors really quickly like in Kanye West's "All of The Lights" music video. Once the display is done, the laptop shuts off. When I first experienced it, it was on my personal laptop. I switched shells and popped my hdd into another one. It ended up happening again sometime down the line. It then happened to my boss' as well. Most recently I've had a colleague report the same issue. Does anyone have an idea as to what could be the issue?

I have the same problem too. I am not using any docking station. It occurs very rarely and I notice it happening when I connect to an external monitor or when in video calls. Happens both in Windows and Ubuntu. I tried switching to a different T420s laptop and I see the same behavior there too (but not as frequently as the other one).
M_Wilson's description of the issue is spot on. The screen flickers colorfully for about 15-20 seconds and then the laptop shuts off completely.
I also noticed sometimes that the laptop gets hot under the part where the display card is present (near the fan outlet vent on the left side). The laptop fan is running at full speed at that time.

External monitor display stopped working

I was on 10.9.2, and from one day to the other, the HDMI connection did not worked any more. My external 27" Samsung remained black. I thought it might come from the HDMI slot on my MacBook Pro Retina (15, early 2013).
I bought a Mini Display port to VGA, did not worked, I tried on other display, don't work, I rest the Pram etc, nothing... I upgrade to 10.9.3. No change.
The display preference Panel does not recognize any thing else than the Retina dsplay... any other display connected is not seen.
I checked the hardwre : diagnostics says everything is alright.
Any idea what the problem is ?
Thanks

According to Apple technician, it's probably a hardware problem... everything else works fine. But for me it is just impossible to work without a larger display.
My MacBook Pro (Retina!) was purchased 1 and a half year ago. The only choice now seems to be to buy a new mainboard. I paid 1500 euro for the laptop, the repairs will cost +/- 1000 euro. Just for a problem connecting an external display.
How can I explain it : it really, really make me furious. More than 20 years along with macs... and so many bad experiences of this kind these last years.
Apple should stop selling computers and stick to smartphones only.
Alright, I will buy next a windows based computer. Oh ! all my professionnal soft are for Mac, I will have to buy them all again...
Traped.
Unsatisfied old customer... who cares ? Nobody.

Wobbly Shakey External Monitor Display

I have a 2009 MacBook Pro connected via VGA with an ASUS e2243fw. On 1400x1050, the screen is fine, however, on 1920x1080, the screen becomes wobbly and shakes uncontrollably.
There is nothing wrong with my adapter because I used it for projectors with high resolutions.
There is nothing wrong with the monitor because I connected it to a different computer, and works at 1920x1080.
My drivers are updated.
My power chord is not around my monitor. There is no disturbance with the magnetic field.
What could be the problem?

Hi Daaniel
Here are the instructions on how to start a new thread:
http://discussions.apple.com/ann.jspa?annID=650
The original poster has a newer MBP (2009) than those covered in this forum (Early 2008 and older with silver keys). The labeling is nonintuitive to say the least. So you have the proper MBP for this area and different video technology that his (the 667mhz RAM in your profile is characteristic of the models covered in this forum area).
Do these video symptoms repeat on the built-in display? If so, your MBP may have suffered the "NVIDEA Curse," where the video chipset fails under load. There is a free repair available to owners of late 2007 and early 2008 MacBook Pros with the NVIDEA 8600M GT video chipset. See this:
http://support.apple.com/kb/TS2377
If the built-in display does not show video defects then suspect the adaptor or the monitor's video cable. The adaptors are not especailly robust and have been kjnown to fail.

External monitor/display for a 2012 MacBook Pro?

I want to know if I can connect an Acer S201HL to a 2012 MacBook Pro i7 2.9GHz 8GB memory OSX10.8.1 - I will be using a magic mouse and apple wireless keyboard as well - if this setup will work what specific cables and adapters do I need to get? If at all possible I would consider running 2 displays. also running Parralells with Windows 7 Home Premium.

With athundebolt diplay there might be some info here that might help.

If you have a mini DVI port you would need a moni DVI to VGA adapter, and a VGA cable

Display not working after using external monitor

I was using my Macbook Air last night to watch via my external monitor displayed to a tv. After I was done, I put my macbook Air in "Sleep" mode via the external display. This morning when I startup my Macbook, I have a blank screen. My suspicians are it's still in the "External display" mode. Anyone experienced this before and found a way to switch back to normal display via key sequence or something?

Reset the NVRAM:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the third time.
Release the keys.

[Solved] Can't get external monitor to display correct resolution

I have a laptop with 1280x800 resolution, I hooked up a spare monitor we had sitting around that has a native resolution of 1280x1024 to my laptop. When I hook it up the external monitor displays a resolution of 1024x768. I use KDE 4.5, so I tried to change the resolution for the external monitor in System Settings but 1024x768 is the highest resolution listed.
I've tried messing around with xrandr through the command line (somewhat anyway) but I'm at a loss in trying to get the external monitor to display its native resolution. I'd like to get the external monitor to possibly replace my laptop monitor as it would add another 224 vertical pixels. Anyone have any ideas?

You had said the native resolution is 1280x1024 -- I therefore assume this is an LCD monitor.
I would not generally expect LCDs to flicker. At what vertical frequency are you driving the display? Most LCDs operate at 60Hz. This is regardless of the local power line frequency or television standard.
Many CRT monitors are driven at 75 Hz to keep them from flickering or from "beating" with ambient lighting that is flickering at the local power line frequency (50 or 60 Hz). Again, this is not the correct thing to do with LCDs.
Bottom Line: Make sure your vertical frame rate is 60 Hz.

External monitor for macbook pro with dead screen

Macbook pro built in 2007 has a dead screen but is otherwise ok. Connected external monitor displays only the astral starburst screen on all macs. How can I get the monitor to display my desktop if I can't see the macbook screen?

Connected external monitor displays only the astral starburst screen on all macs.
Then it is working as designed.
By default, the external screen is combined with the built-in screen into an Extended Desktop, as seen in the Arrange tab below. You need to (Gather Windows) to get all controls on all displays, then drag the tiny white MenuBar to the display where you want it to appear. Then things will begin to operate as you expect.
