Can I connect two external monitors to my 12" Retina MacBook (early-2015)  How do I do it and can it be VGA or only HDMI

I am trying to switch from using my desktop to my macbook pro as my primary machine.  I have 2 monitors (each 1600x1200 resolution) I'd like to use as external monitors for my macbook pro (from 2013).  Both monitors support VGA and DVI input (along with s-video and composite, although I've never used those before).    Looking at the laptop, it has 1 hdmi port, and 2 thunderbolt ports.    The 'about this mac' reports I'm using osX 10.10.4, with a early 2013 15-inch Retina display.  Graphics card is nVidia GeForce GT 650M 1024 MB.  How do I find out if this is possible?  If it is possible, how do I do it?

I noticed in this thread the OP successfully managed to connect a 30" cinema display to the new Macbook Pro USB-C, with full resolution:    I have the official Apple dual DVI adapter, going to a displayport > USB-C adapter like yours, however the screen does not fire up.  I then tried a multi adapter instead of the single displayport > USB-C, which worked but only at 1280 resolution:    Would the official Apple Dual DVI adapter not work?

I have an iMac with a large format display set up as a secondary monitor that we use as a television for watching movies.  When I am just using the iMac, I would like for the secondary display to display something interesting rather than just the wallpaper.  Is it possible to set up a screensaver that appears on the second monitor (I really like the iPhoto slideshow) while allowing me to use the primary iMac monitor?  I would even be happy if it wasn't technically a screen saver, but just any sort of slideshow that could be displayed on one monitor while I work on the other.  Currently if I play a slideshow in iPhoto, the other monitor goes blank. :(

Is it possible to have 2 extended monitors and get the third being a mirror of one of the two extended?   I'm pretty sure it's not possible through the interface but it may be possible through commands or configuration file.  If it's seems weird for you, here is my setup :    2 monitors, pretty classic working with dual monitor 1 big TV that I use as a projector to show things off to people (on meetings for example)

Newer Radeon video cards come with four ports standard:   DVI (x2) HDMI DisplayPort     If I want to run three 24" monitors, all of which are DVI only, from this video card -- is it possible to convert either the HDMI or DisplayPort to DVI? If so, how? And which one is easier/cheaper to convert?  I did a little research and it looks like there isn't a simple "dongle" method. I found this  but it's $120; almost cheaper to buy a new monitor that supports HDMI or DisplayPort inputs at that point!  There's also a  but I'm not sure it will work, either.  AnandTech seems to  that you do need the DisplayPort-to-DVI:     The only catch to this specific port layout is that the card still only has enough TMDS transmitters for two ports. So you can use 2x DVI or 1x DVI + HDMI, but not 2x DVI + HDMI. For 3 DVI-derived ports, you will need an active DisplayPort-to-DVI adapter.

How do I find out the number, type, resolution &amp; refresh rate of additional monitors I can attach to my MacBook or MacBook Pro?  This is an attempt at a canonical QA, as per the Meta QA -   to try prevent the myriad "same but different" questions we get on every possible combination of computers, cable &amp; monitors There are perfectly good resources out there that Ask Different should not have to duplicate the efforts of.

I'm working on a Cocoa Mac app where I need to display a window/view on a secondary monitor, full-screen.  I know how to create a window that could be dragged onto the secondary monitor, but I was wanting to programatically create the window and make it full screen on the external monitor.  Thanks for the help.

The Apple Silicon based  supports Thunderbolt version 3 and I'm wondering if anyone has tried connection one to an ? Of course you'd need to use one of Apple's Thunderbolt 3 to Thunderbolt 2 converters. I also understand that this version is limited to supporting only a single 4K or 6K display, but since the original Apple Thunderbolt Display is only 2K I’d want to try and daisy chain these. Can I run more than one external display from the Apple Silicon M1 CPU/GPU based MacBook Pro (or Air)?

I'm on a MacBook Pro (15-inch, 2018) with Mojave 10.14.1. When I connect MBP to a external displays (either via HDMI or via Thunderbolt 2 adapters), the temperature raises sensibly (i.e., CPU temperature lies constantly over 90°) and fans start running fast (i.e., more than 50%) frequently, even if I am doing very simple tasks (e.g., writing in Word with a couple of Chrome tabs open with stackoverflow).  I'm not sure that the problem started with Mojave or if it isn't actually related to the OS version.  I'm wondering if there is a way to limit this annoying overheating as well as fans activity, while using external monitors.

I am running Mac OS X (Version 10.10.5) on a MacBook Pro (13 Inch, Mid 2010) and want to arrange an external monitor of the same type to different positions.  First, let me explain my setup:   monitor at my office: DELL U2312HM (located above the MacBook's screen) monitor at home: DELL U2312HM (located left of the MacBook's screen)   As you can see, I am using different monitors of the same type (they have different serial numbers displayed in the System Overview window). However, they are located either above or left of the internal screen.  Since the only way I know to arrange an external monitor is draging the blue boxes in the monitor section of the system preferences, I need to do this every morning after connecting my monitor in the office and every evening after coming home. The monitor arrangement does not depend on the monitor's serial number but on the model since saving the arrangement of different models works as desired.  So is there a way, a hidden setting, a hidden setting accessible through the terminal or even a third-party app which enables different monitor arrangements for the same monitor model but based on the monitor's serial number as shown in the system overview?  The behavior which seems to be a system default is very annoying and does not feel very apple-like.

I wanted to use a mini display-port cable then use "target display mode" to make the iMac an external display, but I just read that early 2009 iMac's don't have target display mode as a feature.  Anybody knows of a solution?

I have a MacBook Pro with Touch Bar. I plugged in my external 1080p display (HP 25bw) in clamshell mode and it almost works great - except the screen is too large for the monitor. My dock is too far down off the edge, and my menu is too far up.  For example, when I took the attached screenshot, the Chrome window fills the entire screen I can see:  I have checked and the display options are using native resolution of the monitor (1920x1080 @60hz).  Does anyone have any suggestions for me? Thanks so much.  Note: For any with this same monitor model in the future, thanks to @bmike I found the steps for disabling overscan for this particular monitor model here:

I am using an external monitor and the only way (that doesn't involve jumping through hoops) to turn off the MacBook Pro monitor is to close the lid.  Does closing the lid causes any problems? I have read the following on :     You can still run a single external monitor if you close the lid of   your laptop, but that restricts airflow and exposes your display to a   lot of heat. Not good.

I have two MacBook Pros (one for work; one personal) that I want to connect to one monitor, one keyboard, and one mouse, and be able to switch between the two easily. Typically I'd opt to purchase a KVM switch, but it's been a while since I've needed that type of setup. My questions are:   Are KVM switches even needed anymore for MacBook Pros? Is there some sort of magic Wi-Fi / Bluetooth / Airplay device that can perform the same function? If KVM switches (or something similar) are still used, what's a good make / model that works well with Macbooks? Is a hardware solution even needed anymore? Is there software that can perform the same functions? (For example: Logitech Flow )   Thank you!

I have an external monitor with a VGA connection. What is the best adapter to use for my Retina MacBook Pro? I think I've seen Thunderbolt to VGA, or USB to VGA? Or HDMI to VGA? What are the differences?

I have a HP dv9830us laptop. It has a vga-out and a hdmi-out port.  I want to know if it's possible to use 3 devices, each one with different displays, using just one graphic card - NVIDIA GeForce 8600M GS? (Original, vga with an external monitor and hdmi with a full hd tv). Where I can find this kind of information?  If not possible, I would like to know alternatives like:   "Usb" solutions to be possible to connect to the external lcd or to a TV. The TV should be flawless, but the second monitor can have slow response times; (I've found some , do these units really work?) Cheap PCMCIA video cards to be possible to connect to an external monitor, so I would use the hdmi with the tv and this second video card to output to another monitor.   I'm using Windows 7 and Ubuntu 10.04. Is this possible in both systems?
