I'm unable to connect my 2016 Macbook Pro to a Sharp Acquos monitor (TV) in our conference room.

Window users are able to connect with no issue. The image on my Macbook display briefly changes shape, goes dark then comes back on. This repeats until I unplug the HDMI cable from the Apple USB-C multiport adapter. TV monitors from other vendors in other conference rooms work without a problem. I'm running with the latest update for Mojave. Any ideas?

Windows, Windows 6

Yes....a few...


try the following: reset smc/pmu and then do a pram zap. what version of HDMI cable do you have. Is it HDMI 2.0 "Hi-Speed HDMI" or 1.4 ?

HDMI 2.0 will support 4k. HDMI 1.4 will only support 1080 p. I'd also suspect an HDCP issue. That stands for Hi Def Content Protection which all HDMI outputting devices must have. If any of the devices in the chain from MacBook Pro to Sharp Aquos Monitor (tv) don't support HDCP 2.2, and the source is set to output 4k which means it must use HDMI 2.0 and HDCP 2.2 as well, then it'll be a no-go unless you can set it to HDMI 1.4 which may sorta work, but it'll only give you a picture of 1080 P. I'd also have a look at the USB-C multiport adapter. Apple recently released a newer version of that adapter which does support HDCP 2.2 and HDMI 2.0, and thus 4k. So, you have one of the ones with just 2 ports on it. Those support Thunderbolt 3 and usb-C.


that's a bit of a challenge. I don't know what the Sharp Acquos monitor tv is capable of, 1080 or 4k. If 4k, you might have to turn on HDMI 2.0 on the TV itself and Deep Color as well, if you can, that is.


Otherwise you'd have to go for an adapter/ cable that supports 4k, HDMI 2.0, HDCP 2.2 and works with your 2016 MacBook Pro. Trust me on this one, if it doesn't say that it does for all the things i mentioned before, then it doesn't. Simple, maybe, beating a dead horse, perhaps, but it has to be said.


anyways, check out this amazon link for cable that does support all of the previous things, and should work

https://www.amazon.ca/UGREEN-Thunderbolt-Converter-ZenBook3-Chromebook/dp/B07925J6GY?ref_=ast_sto_dp

it's available in 6 and 10 foot lengths. I don't know if you can get a longer cable.....maybe..... but you'll have to go for an adapter, and then a longer hdmi 2.0 cable........

depending on the tv's resolution and the the adapter and cable, you might have to set your display out for 1080p and be content with that (*well, as content as you can be, anyways*)

anyways, hope that helps you a bit
