I have just got a refurbished 1 Mac mini. I connected via hdmi a tv and a monitor. They are not 4K. When I streamed Hulu or Amazon in Safari I lost picture and just received sound even if only using one monitor. If I only have one monitor connected there isn’t a problem. If anyone could shed some light on this issue it would be much appreciated.
Mac mini, macOS 12.6
Hi there kiwao,
If you don't see an image on one or either display, try the following steps:
Check your cable or adapter
Disconnect the cable from your external display from your Mac, then reconnect it. If the cable from your external display doesn't connect to the ports on your Mac, you can use a USB-C or Thunderbolt adapter. If you're using a USB-C or Thunderbolt adapter to connect a display, the adapter must be compliant with DisplayPort Alt Mode or Thunderbolt / USB 4.
Check how many displays you can connect
If you're connecting multiple displays to your Mac, use the Tech Specs page to find out how many external displays your Mac supports.
1: Choose Apple menu > About This Mac, double-click your serial number, then press Command-C to copy it.
2: Go to the Tech Specs page, click the Search Tech Specs bar, press Command-V to enter your computer's serial number, then click Search.
3: Click the specs page for your Mac. The number of displays your Mac supports appears under Video Support or Graphics.
If your external display isn't detected or appears blurry when connected to your Mac
We hope this is helpful!
Streaming in safari, no picture just sound
