rMBP ethernet kills monitor

[oli356]

Hi all,

I have an issue on my new 13" rMBP. I can have the thunderbolt > DVI adapter plugged in, everything is fine. But as soon as I plug in the thunderbolt > rj45 ethernet adapter the display cuts off and stops working.

Anyone had this issue?

Sounds like a faulty adapter to me.

Agreed. Something is causing a short.

Both of them work OK by themselves and I can plug in VGA and DVI to both thunderbolt ports and that is also fine.

I need to try:
1) Putting each adapter in the different port2
2) Try VGA and ethernet adapter.

You mean both ports on the computer work fine?

I mean that I believe the adapter where you plug the ethernet in is broken.

Or do you mean that ethernet works fine in both ports too? And the only problem is when you plug in one of the others with it? I believe this is what you mean. If you have the DVI plugged in (that is a display thing, right?) and get it set up, then plug in ethernet, does that work ok?

Yes both ports work fine. I can use 2 monitors (DVI and VGA) using both thunderbolt ports.
DVI plugged in and it works fine, as soon as I plug the RJ45 ethernet in the screen turns off. I need to test this more, unfortunately I left the adapters in the office for the weekend.

You could use a usb 3.0 to ethernet adaptor instead

That's not really a fix, a £1300 laptop should be able to be plugged into a monitor and a network..

Then take it to apple to be fixed

The price of a laptop doesn't matter.

If I follow your logic: A $169 netbook has a built-in ethernet port and VGA port and doesn't need an adapter to connect to a network or a screen, so why should a $1500 computer have to? Take that Apple!

You have a warranty, you're entitled to use it, let Apple sort this for you, that's what it's for.
