How to connect Dell U2715H to macbook pro 2016

Hi,

You only need this type of cable:

The adapter works with USB C devices that support DP alt mode, such as the MacBook, ChromeBook Pixel ™, and Dell ™ XPS ™ models 15 and 13. This adapter cable is also compatible with Thunderbolt ™ 3 ports.

That is not a ThunderBolt display. It can not use the USB-C to thunderBolt-2 adapter, which despite its US$50 price, does NOT provide a workable display interface:

Note: This adapter does not support DisplayPort displays like the Apple LED Cinema Display or third-party DisplayPort and Mini DisplayPort displays.

You need a different adapter, and for wider than 1920 wide, the least expensive is a third-party DisplayPort.

Connectivity

2 HDMI(MHL) connector
1 Mini DisplayPort
1 DisplayPort (version 1.2)
1 DisplayPort out (MST)
1 Audio Line out (connect your speakers)
5 USB 3.0 ports - Downstream (4 at the back, 1 with battery charging)
1 USB 3.0 port - Upstream

HDMI at sizes larger than 1902 by 1080p is complicated. It requires special adapters and special cables and sometimes special settings inside the display. And most sellers do not understand what they are selling.

The display in question can do 2560 x 1440, so DisplayPort is a better answer.

That Apple USB-C to ThunderBolt-2 has a specific disclaimer on its product page. It is a data only-adapter, does NOT produce a usable DisplayPort signal of any description, and is not consistent with "the Apple way", i.e., "if it seems like it should work, it will work".

Note: This adapter does not support DisplayPort displays like the Apple LED Cinema Display or third-party DisplayPort and Mini DisplayPort displays. For more information, visit the Apple Support pagefor the Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter.

Return it for a refund. If any Apple employee suggested it, you should try to let them know it is a waste of time, so that they do not continue to confuse customers.

--------

in general, "you cannot 'stack' display adapters". You need to convert directly to the display family needed in ONE adapter.

Exceptions are allowed for [Full size] DisplayPort and [Mini] DisplayPort, because these are the same interface in a different form-factor. Also Single-Link DVI and ordinary (up to 1920 by 1080p) HDMI are electrically equivalent is a similar way. The Apple DVI to ADC powered adapter for certain older cinema displays is also an exception.

--------

for the dell U2715H, you can use a third-party USB-C to [Full size] DisplayPort or USB-C to [Mini] DisplayPort adapter. Ones rated 4K-capable seem to do better. Use caution when ordering from Amazon, as some are mailed direct from the Far East and really do take 3+ weeks to arrive.

This one is cheap and readily available from California USA, but you would need to add a DisplayPort-DisplayPort cable if they did not give you one:

Hi,

How/through what connections/adapters are you trying to connect it?

Obviously, that should work. Does your MBP recognize the monitor?

It makes me wonder about the adapter....

I'm sorry, I have no other ideas at this time.

I'm having the exact same issue

Have you tried mDP to HDMI?
