There appears to be a difference in the 2017 MacBook Pro and 2017 iMac USB-C ports. Many of the 3rd party cable and adapter suppliers are putting compatibility warnings for their products pertaining to the 2017 Mac computers. For example, some USB-C to HDMI cables and some USB-C to DisplayPort adapters from various manufacturers are stating they are compatible with 2015/2016, but not 2017 MacBook Pro/iMac models. Does anyone know what is different with the 2017 model USB-C ports? We've yet to find a reliable cable or adapter to connect to external monitors. The Apple USB-C to HDMI multi-AV adapter is flaky at best. Thank you in advance for any input.

Why do I have difficulty with Wi-Fi or Bluetooth devices when USB 3 devices are attached to my computer? Some USB 3 devices can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer. Here are some tips to avoid this issue: • If your USB device has a cable long enough that you can move the device, place it away from your Mac—and make sure not to place it behind your Mac, or near the hinge of its display. The antennas for Wi-Fi and Bluetooth are located there, and USB 3 devices placed there might interfere with your wireless connections. • If you're using adapters or dongles on a Mac computer with Thunderbolt 3 (USB-C) ports, plug them into the front port on the left side of your Mac, or into the ports on the right side (if your computer has them). These ports are the farthest away from the antennas, making interference less likely.

• To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. You can change this on your wireless base station. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth. From: also, any of these items may be involved: • Power Adapter cable recall • firmware update for the Apple Multi-Port display adapters (specifically to reduce interference). • LG-display recall -- to address Wi-Fi interference so severe, it knocks the Router off the air if too near the Router. HDMI works great at resolutions up to 1920 by 1080p -- that is what it was originally made for.

If you were to use the (electrically-equivalent) DVI family connector instead, it adds an additional three pairs of signals to drive display over 1920 wide, this is called 'Dual-Link' DVI. If you were using a DisplayPort family display, you would also get a quick connection at full refresh rate with no issues. There are number of different things that have to be upgraded to support 4K over the 'never originally designed to run at that high a data rate' HDMI interface.

• Your adapter must support that resolution (and when some say 4K they mean 3840 by 2160, or 3840 by 1600, or 4096 by 2160) • Your adapter must support that refresh rate at that resolution. • Your cables must be rated to support those very fast data rates.

• and sometimes forgotten, your display itself may need its on-screen settings changed to support that refresh rate at that resolution, (and it will be coded, such as HDMI 1.4, HDMI 2.1, etc.). And sometimes even when you get them all perfect it still will only run at 30Hz refresh rate, just because. I just ran into what I assume is the same problem, but on the 2017 Macbook 12' rather than the Macbook Pro or iMac. I have a Fixget adapter, USB Type-C to DisplayPort, which works great on my 2015 Macbook 12', driving an external monitor (a Dell UP2516D). When I unplug the adapter from my 2015 Macbook 12', and plug it into my 2017 Macbook 12', the adapter isn't recognized. I called Apple Support and they didn't have much to offer, other than to acknowledge that the issue seen in this thread probably applies to the Macbook 12' machines as well.
