1001 My display is not being detected on macOS.Jun-21-21
Choose Apple menu > System Preferences, then click Displays. If your Mac doesn't recognize a display you've just connected, hold down the Option key to make the Detect Displays button appear, then click that button.
 
1002 My 4K display is connecting only at 30Hz. Why I can't set it to 60Hz?Jun-21-21
Your display may not support 60Hz. Your display might require a firmware update to support 60Hz operation. Contact the maker of your display for details.

Many early 4K displays use Multi-Stream Transport (MST) to achieve 4k @ 60Hz. Follow these steps to use the display's built-in controls to enable this feature:
Sharp PN-K321: Choose Menu > Setup > DisplayPort STREAM > MST > SET
ASUS PQ321Q: Choose OSD menu > Setup > DisplayPort Stream
Dell UP2414Q and UP3214Q: Choose Menu > Display Setting > DisplayPort 1.2 > Enable
Panasonic TC-L65WT600: Choose Menu > Display Port Settings > Stream Setting > Auto
Other DisplayPort displays: check with the display manufacturer for compatibility information.

HDMI:
Make sure the HDMI cable you are using is a Premium High-Speed HDMI Cable certified by HDMI.org.

If you are trying to connect at 4k@60Hz via HDMI 2.0, you may have to set the color depth to 8-bit at 4:4:4, 10-bit at 4:2:2, or 12-bit at 4:2:0, or you may exceed the HDMI 2.0 bandwidth. A few 4K TVs (2017 Element Fire TV and 2017 LeEco Super 4, for example) don't support 4K@60Hz@4:4:4 at all.

For connecting to a 4K TV, you may need make a custom color resolution. Set resolution to 3840x2160 at 60Hz and set Timing standard to CVT-RB (reduced blanking). Some TVs require you to turn on "UHD Color" or "Advanced" or "Enhanced" setting manually in the picture settings for the HDMI port.

1025 Will a Sonnet eGPU accelerate internal video on a Mac?Jun-21-21
If you are using macOS 10.14.6+, you can accelerate applications with the external GPU (if they support GPU acceleration)...
• Select the app in Finder
• Get Info
• Check Prefer External GPU

Adobe Premiere and Apple Final Cut Pro automatically use the eGPU when appropriate. Do not select Prefer External GPU for these applications.

Some professional applications let you select the external GPU (or multiple GPUs) in their preferences.

1054 How do I extend the length of a DisplayPort cable?Jun-21-21
1084 I connected my monitor to the Breakaway Box, Breakaway Puck, or DuoModo eGPU Module on my 2018 or newer Mac mini, but it boots with a black screen.Jun-21-21
1110 I'm trying to use four HDMI monitors by adding DP-to-HDMI adapters, but it doesn't work.Jun-21-21
Use at least one active DP-to-HDMI adapter.

Display Port signal is not compatible with HDMI.

However, on most modern GPU cards, the DisplayPort output is a Dual mode DisplayPort (DP++), which has the ability to recognize and adjust the signal to HDMI when a passive DP-to-HDMI adapter cable is connected, but only up to a point. If the HDMI monitors you are trying to connect are identical (use identical video signal timings), then you should be able to use passive adapters for all. However, if the monitors are different, then there may be a limit of two special clocks to drive passive DP to HDMI adapters; ergo only two HDMI monitors may be supported with passive adapters; the third and subsequent monitor would need to be native DisplayPort or would need to use an active DP-to-HDMI adapter.

Older generation GPU cards require the use of active DP-to-HDMI adapters on every DP port.

1145 Do not disconnect or power off you eGPU during sleep or your Mac will crash.Apr-20-21
macOS does not support disconnecting or powering off an eGPU during sleep. If you do so, your Mac will kernel panic. This is an issue that persists through at least macOS 11.2.3. Sonnet has reported the issue to Apple.
 
1191 I upgraded to macOS 12.4 and my Vega 56 is no longer seen by macOS.Nov-25-22
If you had Filevault turned on during the update, then you need to turn Filevault off and then on again. This should fix the issue.
