Solved SP 4 4k@60Hz issue

[dwib44]

Trying to use this tv:

https://www.amazon.com/VIZIO-D40u-D...01A0LGV06/ref=cm_cr_arp_d_product_top?ie=UTF8

as a 4k monitor at 60hz with my surface pro 4. Only able to get it to work at 4k 30hz. Using this adapter:

https://www.amazon.com/Cable-Matter...Technology/dp/B00PJ3LSIG/ref=cm_cd_al_qh_dp_i

And this hdmi cable:

https://www.amazon.com/gp/product/B00NQ9OQU2/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

All support 4k at 60hz and others have used the same cable and adapter to get a samsung tv to work with SP4 at 4k@60hz

The hdmi is connected to hdmi 5 which supports 4k at 60hz and specifcially says it is the port for 4k 60hz.

As is typical for others doing this with other 4k hdtv's initial connection starts at 30hz but when 60hz is selected it has worked with the same hardware and a different hdtv for others.

When I try to select 60hz the sceen goes blank until the computer reverts the settings to 30hz. All hardware supports 4k 60hz and others using the exact same hardware but different tvs have had success yet I have not. Is there any possible solution or things that I can try to get this to work? I don't understand why this wont work when all hardware supports 4k@60 and the option for 60Hz is given as an option. The tv has other hdmi ports that only support 4k@30 and when connected to these the 60Hz option does not show up as would be expected. The port that supports 4k@60 does give the option, it just doesnt seem to work. Any help would be greatly appreciated

Is this through the dock or direct into the side of the SP4? I have the same TV here at work (different adapter and cable) and I can get 60Hz, I use the same adapter/cable as you on another TV in my home office and works as expected.

I get the problem plugging directly into the SP4 and when plugged into the dock. Which adapter and cable do you use? Maybe those will work for me.

Also when setting up the vizio TV was there any settings you had to change to get it to work at 60hz other than changing the rate to 60?

This Adapter -

Plugged into HDMI 5 which is the only 60Hz Port on the TV and it just runs at 60Hz...

Sounds like it is working for you as I was expecting it to work on my end. Ordered both, should get them Tuesday. Also ordered a few other similar adapters so hopefully one of them ends up working for me. Good to know that this should indeed be working and that there isn't some compatibility issue that I completely missed. I will update once I have tested the new parts.

This did the trick! This adapted does 60Hz as promised and is much smaller which is a plus as well! Thank you so much for the help!
