Have you tried setting up your screens with SwitchResX? It has settings for each unique display connected to your computer. The app cost a couple of dollars, but theres a 30day demo to try if it helps you.

So the final answer on this, supported by links in comments and answers above is that the documentation says clearly there are only two possible ways to achieve what you are looking for. Either you daisy chain thunderbolt displays (obviously doesn't work for you). Or an hdmi and a true Thunderbolt Display. The first of those two possibilities is spelled ...

Screen-sharing may work for you in this instance, if the computers share a network. Note this is not a hardware (cable) solution, but it may work sufficiently well for you. From the iMac's Finder, locate and click on the MBP's icon from the left window pane. In the title bar of the right pane, click on "Share screen...", authenticate, and begin your work. ...

To the best of my knowledge a 'Thunderbolt to twin VGA' adapter does not exist. I think what The Projector Company are suggesting are the Matrox DualHead2Go adapter boxes. The premise of these adapters is they connect to two displays (or projectors) and present a single connection to the computer. They present the two displays as a single super-wide display ...

You can drag the title bar of the browser window over to the other display. If you open the System Preferences > Displays, then Arrangement tab, you can see where the projector's display is in relation to the laptop display. The main display (typically the laptop's) has a tiny white menu bar depicted in this Arrangement window. Just click-drag the window ...

Display Maid seems to be designed to do this: Display Maid is an app for keeping your displays tidy and managing your workspaces. If you use an Apple laptop with an external monitor you probably know how frustrating it is trying to keep apps and windows organized when you have to unplug your display. Everything gets jumbled up on your main screen and ...

i have the same problem, i noticed that it happen if i start or resume my mac with the external display connected, if i connect it after the mac is wake up it behave normally. Probably it fail to detect the correct setting for monitor during startup (or something messed it up as wake up) So not a fix but at least you can work..

I can't test your setup so I can't help with this esoteric bug but I do know of an app that may help. Check out Moom. It's primarily a window-snapper utility, but it has a unique feature in which you can setup window layout snapshots based on the currently available windows. Here's the kicker: you can set the pre-defined window layout to trigger ...

Same problem here. Unplug and plugin again helps (display port). After that the photoshop dialogs are complete visible (main system dialog: save, open...) - but the order of photoshops internal windows (layers...) are broken.

No, what you're asking for doesn't even make sense. If you want the display to be mirrored, then what's on the external display has to be exactly the same as what's on the internal display. What you need is a new external display with a larger physical screen size.

Is your MacBook a late 2013 or mid 2014 (Thunderbolt 2)? If not, there is no chance to support DisplayPort MST (Multi Stream) which allows you to daisy-chain two of the Dells. The late 2013 and mid 2014 macbook pros have thunderbolt 2 with DisplayPort 1.2 (Thunderbolt 2), all the other macbook pros with retina just have DP 1.1 (Thunderbolt 1) which does not ...

I have a similar setup and now that I'm thinking about this, using Spaces is the key. Go to System Preferences > Mission Control Enable "Displays have separate spaces" In the Dock, right-click (or option-click) an app. Under Options, assign that app to the appropriate space and display. I'm currently at home where I only have a single external monitor ...

Unless you bought a very old iMac, its external display port is most likely mini-DVI. If you have something as old as a G4 (the "desk lamp"-looking iMacs), it may be a mini-VGA port. A helpful resource for identifying your model and seeing details of its capabilities is everymac.com - those are the only options I see for any of the 17-inch iMac models.

I have seen three monitors connected to a 2013 15" MacBook Pro. One was an Apple Thunderbolt display connected to the Thunderbolt port. The second was a display connected over either a DVI or VGA adapter plugged into the second Thunderbold port on the Mac, and the third was an HDMI connected directly to the HDMI port on the right hand side of the Mac. The ...

Same thing happened to me. You have to manually change it in System Preferences > Sound > Output Volume.

You can use thunderbolt to hdmi or thunderbolt to vga cable to connect the other monitor.

I did have this with my Mac Air and it was a bad cable. I replaced it and then it would crash, if that happens try this: system prefs > security > advanced > uncheck logout after xx minutes of inactivity Someone on this site suggested it for display crashes and it worked beautifully for me.

I keep my dock on the right side of the screen which keeps it on one display, i.e. the rightmost display when I set up the arrangement.

As sudo-workaround. I recommend hiding the dock. It feels a little more natural to me. At least until they allow the option to keep in on one display.

Go to the system prefs -> power options then configure the sleep option.

I was in that situation some time ago. The only way that seems to work without issuing the shortcut with Apple keyboard I found was this in Logitech forums. I have successfully implemented what I believe is a reasonable workaround. Here's what I did... Purchased and installed Keyboard Maestro from Stairways Software. Within Keyboard Maestro I ...

According to EveryMac that machine can only support one external monitor, at 1920x1200 resolution.

Thunderbolt is an active technology, Display Port is passive. To daisy-chain, you must use Thunderbolt to Thunderbolt. You cannot daisy-chain Display Port. Your solution may be to find a 3rd party Thunderbolt -> dual Display Port box, but it's not something I've investigated, personally. Google gives this for starters.
