how to connect macbook pro with projector

how to connect macbook pro with a projector?

Hello,

To add to lllaass great advice, you can find the appropriate adapter by using this apple link: About Apple video adapters and cables - Apple Support

Good Luck!

Get an appropriate adopter to connect your Mac's video out port to an input port on the projector.

If yo Mac has a Thunderbolt port that accepts a mini displayport for video output

A projector is just a special case of a second display (one which throws the picture up on the wall, rather than on a small screen nearby).

The default setting is to create an Extended Desktop from the two displays, that looks like the illustration below. The mouse moves freely across the boundary between the two displays, so you can drag a window onto the second display.

If you get "just wallpaper" on the second display, it is working as designed.

Everything shown in this window, the blue screen areas (proportional to screen pixels), their positions relative to each other, and the menuBar, are icons that can be dragged into different positions.

I have a 2017 MacBook Pro (OS Sierra 10.12.5) with 4 usb c ports.

I sourced an HDMI to usb 3.1 adapter and plugged in my HDMI projector - "No Signal" (Toshiba TDP-E20)

There is nothing in the MacBook Pro preferences to show screen arrangement. Have tried restarting with projector plugged in. Have power adapter connected.

Still "No Signal"

Can someone please advise me. Thank you.

what adapter, exactly?

Hello Grant

Thanks so much for getting back to me

The adapter is HDMI to USB 3.1 - with MHI 2.0 1080p@60HZ (from eBay)

Regards

Ben

Sorry meant HDMI

Can you tell me what the spec of an adapter needs to be to work with the Macbook Pro and an HDMI projector - maybe HDMI 2 is not backwards compatible. I think I can test the adapter with an HDMI monitor, will get back on this.

Any help much appreciated

Have a good weekend and Best Regards

when I asked what adapter, exactly, I hoped you would reply to a link with the tech specs or an unambiguous name that could be used to find the tech specs.

I am also wary about your calling this a USB-3.1 adapter rather than a USB-C adapter because I fear you may be trying to "stack" adapters, which does not usually work for Display Adapters.

Hello

Thank you for your reply

As described I am only using one adapter, if that is what you mean by stacking

The only information I have on the adapter is HDMI 2.0 to USB 3.1 - MHL2.0  1080p@60mhz

The print for the last bit is quite small so I was confusing MHL with HDMI

Are you able to help with this information?

I have now purchased an apple adaptor (USB-C Digital AV Multipart Adapter) but still no joy.

This projector is definitely working.

I would be very glad if anyone can help or suggest what the problem is.

so you are connecting, with ONE adapter, directly to an HDMI input on the projector?

What does it say at:

 menu > about this Mac > (system Report) > graphics and displays ...

... is the adapter listed there?

... is the projector listed there?

Hi Grant

Thank you for your reply. Yes I did make that clear previously that I was not 'stacking'.

I just now received and downloaded a mac update specifically for the usb c multiport adapter and the projector worked as soon as I restarted. The hdmi projector is now recognised as a second display - I am very glad that this issue is now fixed. 

However it is frustrating that the port not working was a mac software issue.

Best regards

Where is the download that fixes the problem? I have the same issue.
