Thunderbolt 2 display to 2020 MacBook Air w/ USB-C

The fact that it fits into the Thunderbolt port does not mean its a thunderbolt cable.

It could very well be a Mini Display Port cable which uses the same type of port, but would not work with a Thunderbolt display.

If your cable has a square with two lines instead of the lightning bolt arrow, its a Mini Display Port cable.

Can you post a picture of your cable ends please?

Hi,

I suppose your Thunderbolt2 extend cable is actually mini display cable, since it's quite hard to find Thunderbolt2 extend cable.

Just to clarify:

This is a female Thunderbolt 2 connector:

And this is a male Thunderbolt 2 connector:

What exactly does your cable have?

Can you post a picture?

Hi,

Mini Display cable is also same shape and connector with Thunderbolt 2 connector.

You said that the cord is shorting out several times a day.

This would be different than the case of the permanently-attached cable not being reliable – but also not shorting out components within the display. A cable with electrical shorts could cause damage to your display or adapter – damage that plugging in a bypass cable would not undo.

Re: “What would be the reason for shorting out?”

You are the one who reported that it was shorting out. I cannot inspect your cable to determine what insulation has been eroded away to allow wires that should never touch to make contact.
