Officially, the late 2012 Mac mini will support two monitors in the following combinations: one HDMI monitor while using one Thunderbolt monitor two Thunderbolt monitors. As for the supported resolutions, the late 2012 Mac mini supports up to 2560 x 1600 on Thunderbolt monitors or up to 1920 x 1200 on HDMI monitors. Of course the above is the official ...

You dont say which 2009 iMac you have, but even the Late 2009 27" seems to support only one external display, up to 2560 x 1600. (From things like Everymac.com and MacTracker) How have you managed to get two external displays running from 1 miniDisplayPort? I doubt very much whether these machines have sufficient graphics hardware to drive 3 displays - ...

I happen to have a 2012 non-Retina MBP 13 and a 4K monitor and I just tested this. You can run both displays and the monitor will max out at 1080p @ 60 Hz. You can game on it at that resolution as well but there are noticeable frame drops. So yes, it should be possible. I was using a Mini-DP to HDMI dongle in between as well.

I wrote a free terminal tool called displayplacer that lets describe your monitor layout as a terminal command. I then use BetterTouchTool to execute these profiles via hotkeys. It solved the same problem for me of using the same model monitor at work (in portrait mode) as at home (in landscape mode). For example, on my 4 monitor setup at home I have this ...

I wrote a free terminal tool called displayplacer that let's you describe your layout and re-apply that same layout. It will let you set up profiles for changing the resolution, rotation, and positioning of your monitors. For example, he's my 4 monitor setup profile. I have this command tied to a hotkey using BetterTouchTool. displayplacer "id:A46D2F5E-487B-...

The free terminal tool I wrote, displayplacer, allows you to configure the "white bar" primary display via scripts/hotkeys. Configure your screens how you like, drag the "white bar" to your primary screen in the macOS system settings, and then execute displayplacer list. It will output the command to run to put your screens in their current configuration. ...

Check out the tool I wrote called displayplacer for setting monitor configurations via profiles. Since your goal is to treat the same model monitor differently you may need to use the contextual screen ids instead of persistent screen ids. Be sure to read the Notes section on GitHub for more info on this.

Even in 2019 macOS fails to preserve my monitor layout. I wrote a tool called displayplacer that lets describe your monitor layout as a terminal command.

I wrote a tool called displayplacer that does exactly this. It will let you set up profiles for changing the resolution, rotation, and positioning of your monitors. For example, he's my 4 monitor setup profile: displayplacer "id:A46D2F5E-487B-CC69-C588-ECFD519016E5 res:3840x2160 hz:60 color_depth:8 scaling:off origin:(0,0) degree:0" "id:F466F621-B5FA-04A0-...

For multi-monitor setups the tool I wrote, displayplacer, does this. Configure your screens how you like, drag the "white bar" to your primary screen in the macOS system settings, and then execute displayplacer list. It will output the command to run to put your screens in their current configuration. The screen with origin:(0,0) is the main display with ...

I wrote a command line tool called displayplacer that let's you change screen resolutions through scripts for both single and multi-monitor setups. Configure your screens how you like and execute displayplacer list. It will display the command to run to configure and arrange your screens in their current setup. For example, this sets my 4K screen to "1080p"...

I wrote a command line tool called displayplacer that will help with this. You can specify the resolution and positioning of your various monitor setups. Setting a screen with origin:(0,0) will make it the main display with the white bar in the settings. Execute displayplacer list to get your screen ids. Example profile 1 with MacBook screen displayplacer "...

I'm having success so far at least by trying this answer to a similar question posted in 2012. I wasn't looking back that many years because I thought it wouldn't apply, but it looks like the same problem. Switching my TV to Thunderbolt Port 1 on the Mac seems to be avoiding the problem for the moment. Now using Port 2 for my other external monitor, but ...

While it may be a bit cumbersome, I use the Rectangular Selection Tool, then go to a corner of the image that suits your coordinate system (top-left in some cases, bottom-left in others) and stretch the rectangle to the desired position. The size of the rectangle shown in the tooltip will be your position. Zooming in helps to be more precise.

I'm a little sad there isn't more love for Keyboard Maestro. It, is by far the most powerful app on my mac. In addition to having built in window and application switchers, you can also set a keyboard shortcut to focus (or launch, if it's not open), and app, and you can decide if you wish for it to pull up all windows, or just the top most. The way I set ...

As I don't want to install any software nor want to use Terminal for such a trivial task (nor have found any setting allowing me to never have my Mac sleeping), I use this: https://www.youtube.com/watch?v=G1IbRujko-A Apparently, opening a Youtube video and keeping the focus on its tab prevents Chrome from sleeping (as you fake watching a video) and allows ...

According to Apple's specifications on this MacBook Pro all four ports support video: Charging and Expansion Four Thunderbolt 3 (USB-C) ports with support for: Charging DisplayPort Thunderbolt (up to 40 Gbps) USB 3.1 Gen 2 (up to 10 Gbps) If two of the ports are not supporting video you could look at the cabling (try another cable, etc.) and ...

The 2017 MacBook Air does not natively support dual external displays. When you connect a monitor through the mini-DisplayPort, you'll only get a single display. Even when using the splitter - you'll always get a single display mirrored across both monitors. The 3-in-1 mini-DisplayPort adapter is meant for converting the DisplayPort signal to one of three ...

In order to get this setup working, you'll want to get the following: 2 x Thunderbolt 3 to HDMI cable 1 x DisplayPort to HDMI adapter-cable 1 x USB-A to USB-C adapter You would connect the first monitor directly into the MacBook Pro using the Thunderbolt 3 to HDMI cable. The second monitor connects to the dock's Thunderbolt 3 connector using the ...

No. This will not work. You will need to get a display with its own power supply. Thunderbolt 1/2 doesn’t support power delivery. Even though Thunderbolt 3 does, connecting an adapter doesn’t magically make power appear. The (up-to) 9W of power is bus power - you can’t assume that because it’s there, it can be utilized, especially to power a device. ...

i had same heating issue for more than 6 months till i tried this and then everything is just fine.

I broke my head for 3 months and finally only one solution worked. Install Fan control app and then increase the fan speed to 5000 RPM. All heating issues gone.. Now whether its external display or heavy applications, Mac is always cool.

This is not possible with the current macOS. It would be necessary to write a screen saver that explicitly understands you want to draw across multiple screen surfaces.

You need a Thunderbolt 3 dock - many exist. What you seem to be confused about is that they require a Thunderbolt 3 monitor - they don't. You can buy a simply cable to connect the Thunderbolt 3 port on the dock to the monitor via DisplayPort or mini-DisplayPort. I'm using the OWC 12-port Thunderbolt 3 dock for attaching dual-monitors to the MacBook Pro ...

Can you supply a screenshot? Greyed-out files in file dialogs usually mean that those items can't be selected. For an Open dialog, greyed files are ones than can't be opened by the app. For a Save dialog, it's normal for existing files to be greyed out, because you're not going to select them, you're creating a new file. (However, you can actually select ...

When you're on the new Macbook Pro (post 2017), and you connected your external display to the right side of your macbook, the refresh rate settings dropdown may be disabled.

It sounds weird but anothet thing to try is if you have the Macbook touching the LG5K display in any way it causes some sort of earthing issue. As you know the Macbook aluminium case is a conductor and there are minute amounts of current generated on the shell by the Macbook Pro itself. If these currents find their way to the LG5K display it causes erratic ...

I think that you need to change a setting of your Dock! Or do you maybe have an app to organise your desktops or not? I just remember this: click on the green circle top left corner (button to go full screen) but you hold the command key down while clicking and dragging the window to the left or right and normaly, it will set the window of your app to go ...

Reading this guide may help you: How To: Run External Displays with your USB-C/Thunderbolt 3 MacBook It helped me a lot, although the guide is from a dockstation manufacturer, it's somehow neutral, and addresses in a practical way the different scenarios that we can face when we want to work with multiple screens in our MacBook Pro, either using a single ...
