The Displays menu has a few different tabs. Open System Preferences and then click Displays. If you have more than one monitor attached to your Mac, a window will pop up on each one. If you want to use your external monitor as a second monitor, you’ll need to set things up. With Apple and Windows historically living in such separate camps, it's nice to see a product bring more platform agnosticism for those who aren't completely committed to one side. In System Preferences, click Desktop & Screen Saver. The iPad must run iOS 12.1 or later, and you need either 802.11n Wi-Fi or an Ethernet connection. Note that to use Luna Display in general, you must have a system with Windows 10 64-bit, Build 1809 or later, or macOS 10.11 El Capitan or later as your main PC. Finally, there is MaxiVista - this one is one-way, only uses Mac, Windows or Linux as a remote monitor for. Air Display also used the host computers screen resolution nicely, but at times motion became choppy. Again, this feature works whether the iPad is connected to a Mac or PC. However, you have to pay for each machine (1 at a time) that you use as a remote monitor - opposite of how ScreenRecycler is licensed. Any Thunderbolt-equipped Mac should be able to support resolutions up to 2560 x 1600 which would mean that my humble 11 MacBook Air would be compatible with the 30 Cinema Display with a suitable adapter.
#Secondary screens for mac 1080p
Other additions with the Luna Display 5.1 update include support for Apple's Magic Keyboard and trackpad with a Luna Display-connected iPad. Most displays are usually 1080p or above which should be the minimum you’re looking for. And if you're "only" connecting a 4K screen, your refresh rate will be 60 Hz, whether the display is connected to a Windows or Apple system. The logic of putting a secondary screen on the back of a gaming phone causes more questions.

If you're using a Mac with Big Sur or later, the refresh rate is increased to 45 Hz. Say, if the secondary screen on the Mi 11 Ultra is acceptable for selfies, for vlogs, it won’t work well. I would like to add a U27222D, which has only 1 x DP.
#Secondary screens for mac manual
I would like to add a second display to it, but I am confused about what monitors will work with it because the manual says it supports two monitors up to 4K with one on HDMI, one on ThunderBolt.

Any 5K screen connected to your Windows PC will be limited to a 30 Hz refresh rate, which is half the refreshes per second than what's typical (60 Hz). I have a 2020 M1 Mac Mini that has a 2560x1440圆0Hz monitor (U2719DX) connected to the HDMI port. If you plan to connect a 4K or 5K Mac, the machine has to be running at least macOS Big Sur.
