Your model MacBook Pro can power external displays at 60Hz in the following combinations:
One display at 5120 x 2880 resolution with over a billion colors
Two displays at 3840 x 2160 resolution with over a billion colors
Two displays at 4096 x 2304 resolution with millions of colors
So, to use both the 5K and 4K displays you need to be mindful of the ...
I would try a third party executable that will allow you to list and change the screen resolution from the command line. cscreen works on macOS Sierra, High Sierra, and Mojave, there are also several projects on Github, but your mileage may vary.
Apparently, the MacBook Pro can only power external displays up to 5K resolution.
What you can do to use both the monitors is:
Connect one of the monitors (preferably the 5k first) and lower it's resolution way down, up to 720p perhaps, by following the steps as illustrated in
Then connect the other monitor(...
Re connecting a Mac mini 2018 to 30" Apple Cinema Display*:
* Apple Cinema Display 30" refers to TFT-LCD model (M9179LL/A) only! This does NOT work for the LED apple cinema displays.
You need the following:
Power Adapter of the Apple Cinema Display
The apple mini display port (mini DP) to Dual Link DVI adapter (sold second hand only, 30-150 USD) apple ...
What worked for me was switching cables. At first I was using a USB-C to HDMI adapter. When I changed the plug to connect the monitor with my MacBook without the adapter it started to work without any issues.
As a start I think we need to establish if you can get your display to work correctly while your MacBook Pro is in closed-clamshell mode. To do this, follow these steps:
Connect a USB keyboard and mouse to your MBP (or pair a Bluetooth keyboard and mouse with your MBP)
Connect your MBP to an AC power source
Connect your Viewsonic display to your MBP
I had the same issue with Mojave 10.14.6.
The j5Create worked perfectly until installing the supplemental update to the OS. With Apple trying to fix blacked-out/locked screen issue, whatever they did in the update broke j5Create.
Assuming your cable is connected securely at both ends, the first thing to try is connecting the HP V270 display to a different USB-C port to see what difference, if any, this makes.
If this has no effect then I'd reset your NVRAM.
Resetting the NVRAM
Your Mac uses Non-Volatile Random-Access Memory (NVRAM). To reset the NVRAM on your MacBook Pro model ...
Take it to an authorized apple repair facility. They are the only ones that can get new parts. The labor is reasonable, $75 an hour if I remember right. You can try and go with a used screen but you're taking your chances. If you have apple care then they might replace the screen for free. I can tell you that the retina screen is about $450 on a MacBook....
This solution works for me using Keyboard Maestro.
Steps to do it:
Create a new trigger: name it something like Screenshot Active Monitor
Add a hot key trigger. I use Print Screen button on my keyboard (which is F13). You can use any shortcut that work for you.
Add following actions to execute on the above keypress:
1. Type a combination of the keystrokes ...
This model supports a simultaneous maximum resolution up to 2560x1600 on two external displays via Thunderbolt. Alternately, it can support a single display up to 2560x1600 via Thunderbolt and a single display up ...
This is the correct behavior. The actual resolution of the panel is 2880 x 1800, but macOS scales the UI to simulate 1440 x 900 @ 2x by default.
You can change the scaling factor in Display preferences to "create" more screen space. If you set it to the highest setting, 1920 x 1200, then you'll be able to drag a window from the external to the internal ...
I'm assuming your Mac is running macOS Sierra or later and your Mac has Night Shift enabled (by default Night Shift will change the appearance of your screen at night).
To access Night Shift settings go to Apple > System Preferences > Displays and select the Night Shift tab (see screenshot below):
Depending on your version of macOS your Displays ...
Reinstall VMware Tools
As was often the case with the competitor Parallels you mentioned, when the screen resolution fails to adjust you may need to re-install their software that embeds within the guest OS to enhance integration with the host OS.
From the main VMware Fusion app menu bar, choose Virtual Machine > Reinstall VMware Tools.
This mounts an ...
CalDigit Thunderbolt 3 Mini Dock
Dual DisplayPort or HDMI versions of the CalDigit Thunderbolt 3 Mini Dock are available.
I use the Thunderbolt to dual DisplayPort version on a recent Mac. It works well enough and is bus powered. Very rarely one of the displays will not appear on start up; unplugging the adapter or restarting fixes the problem.
Knowing that this question is rather old I want to make you aware of https://github.com/the0neyouseek/MonitorControl which is open source, well maintained and quite handy.
You can control brightness, contrast or volume directly from a menulet or with keyboard native keys. Keyboard keys even display the native osd.
Same issue here, I bought a 2018MBP 512GB/16GB/I7 version, when I connect to my LG 4K (27UK850) display on the right (using equipped USBC to C cable), it only output 1920*1080 30Hz, the mouse and window is lagging with shadow, it is killing me, while my previous model 2016MBP 512GB/8GB works fine with this display, it can output 60Hz from any of 4 TB3 ports. ...
I set my windows to what size I like. Here is how I use my web browser.
You can adjust the windows to what size you like. The come back to that size the next time you start.
For some reason, Windows seems to want you to work on one app at a time in full screen. In the mac, I have multiple apps open at once.
One of the great features of macOS for me, ...
If by HP27fw you mean this display, then you may have gotten a fairly low end 27 inch display.
For example on my work PC (Optiplex 7060, Win-10) I have three Dell 24-inch displays that are set to their native resolution of 2560 x 1440. So, you ask, what does that have to do with my display on my Mac? Glad you asked.
The specs of that monitor say
I had this problem and it was the USB-C to HDMI adaptor. I changed brands, I now have insignia (best buy brand) and the issue went away. I don't know if it was a compatibility issue or if I just got a bad one... I don't know what about the different adaptor fixed it.
Yes, simply go into System Preferences->Display. A new window will pop up on your primary monitors, as well as your external monitors. The external monitors should have a "Rotation" drop down menu, in which you can select "Standard", "90º", "180º", and "720º". If you select "90º" and hit "Scaled" under the resolution option, you'll see that the standard ...
I had no previous problem in eyesight. But after start using Macbook pro 13-inch, i had to start using glasses. I though my eyesight was getting low and lower. But I see a major difference when I use PC with normal LED monitors. I dont even use glasses. no strain on my eyes.
If i use same LED with macbook pro attached, i have to use glasses. I think its ...
Browse ifixit.com and you can see ifixit's part numbers for these two 13" Retina MacBook Pro machines.
The "Display LVDS cables" on the two MacBooks carry the same ifixit part numbers. The two models' "Screen Assemblies," however, show different ifixit part numbers.
Because the screen part numbers are different, I think the answer to your question is "...
Nimesh Neema is correct, you cannot use your iMac in Target Display Mode as this feature has not been supported in iMacs manufactured for about the past five years.
However, there are some software options you can investigate, but I have no personal experience with them. Two of these options are listed below:
In summary, they ...
I use a dual display set up myself. Under the display settings you can arrange which display is where (physically located on your desk) with your MacBook display being the main display.
As of now, I have my dock pinned right on my widescreen “main display” and it does not display on my vertical display. This is in Mojave.
Your only options are both workarounds:
Uncheck "Displays have separate Spaces" under System Preferences > Mission Control
Pin dock to right or left instead of bottom (obviously not ideal if you're a bottom pinner)
