Information about these and other types of Mac ports is in the specifications for your Mac: Choose Apple menu > About This Mac, click Support, then click Specifications. Or check your Mac user guide.
Thunderbolt 3
Use Thunderbolt 3 with displays and other devices that connect using either a Thunderbolt 3 cable or USB-C cable. You can also connect a USB-C power adapter and cable to charge your notebook computer. If you have a device that doesn't connect to this port, you might be able to use an adapter to connect it.
These Mac models have Thunderbolt 3 ports:
- MacBook Pro introduced in 2016 or later
- MacBook Air introduced in 2018 or later
- iMac introduced in 2017 or later
- iMac Pro (all models)
- Mac mini introduced in 2018
- Mac Pro introduced in 2019
See the following from Apple USB SuperDrive - Apple. MacBook, MacBook Air with Retina display, and MacBook Pro models with Thunderbolt 3 (USB-C) ports require a USB-C to USBAdapter (sold separately) to use Apple USB SuperDrive. I just got a U3219Q and I'm trying to connect my late 2015 MacBook Air to it via the USB-C input on the U3219Q. It doesn't seem to be working. I'm getting 'no USB-C signal from the device'. This doesn't really make much sense to me as 'USB-C' is not a signal, I assume its is expecting using USB 3.1.
If your Mac notebook or desktop computer has more than one port like this, each port supports ThunderBolt 3 and USB-C.
USB-C
Use USB-C with displays and other devices that connect using a USB-C cable. You can also connect a USB-C power adapter and cable to charge your notebook computer. If you have a device that doesn't connect to this port, you might be able to use an adapter to connect it.
MacBook models introduced in 2015 or later have a single USB-C port. This port doesn't support Thunderbolt devices.
If your Mac has only one port like this, it's a MacBook that supports USB-C but not Thunderbolt.
Thunderbolt
Use Thunderbolt or Thunderbolt 2 with displays and other devices that connect using a Thunderbolt cable.

Thunderbolt and Thunderbolt 2 are not the same as Mini DisplayPort . They have the same shape, but use different symbols on the cable and port. However, this port does support Mini DisplayPort for video output, so you can use a Mini DisplayPort cable to connect a Mini DisplayPort display.

I've tried submitting a ticket which they never replied to. I have a j5 create hdmi to USB adapter and the model is JUA254. I got this to be able to watch Netflix from my laptop and display is on my tv. When I bring up Netflix it doesn't play and the Netflix screen turns green. Has anyone else had this problem?
I have a Mac air and have installed the correct software according to the instructions.
JUA254 needs USB 3.0 port. Does your Mac Air have one to use for it? If not, did you try lowering the resolution of the TV from 1080p to 720p or?
One site for Apple says the Air has USB 3.0 and HDMI. Why don't you use that? Why have a cable if your TV is wireless or wired network smart TV? You could cast to it from the Mac Air.

To connect a MacBook Air to an external display (including a TV) your best bet is a Thunderbolt/Mini DisplayPort to HDMI adapter. You'll generally get better results than a USB to HDMI converter.
