4K@60Hz output is OK here.
nuc6i5syk, Win7x64 / Ubuntu 64, ViewSonic vx2475, Mini-DP to DP cable.
With Bios 45 and HD graphic drivers 18.104.22.16854, actually with many older versions, no problem at all.
Thank you very much.
I have the same issue if I boot on Ubuntu.
In windows I managed to create a custom resolution in intel graphics control panel and forced 60Hz in CVT-RB.
I can only force GTF to 52Hz and then get a message that the bandwidth is not sufficient.
Petronius, have you tried installing the Beta driver? Please give it a try Download Intel® Beta Graphics Driver for Windows® 10 and Windows 7*/8.1* [15.40].
Have you tried setting the refresh rate to 59Hz?
the beta drivers do not change the issue.
59hz is not available, only 29hz and 30hz.
I can however create a custom resolution in intel graphics control panel and force 60Hz in CVT-RB.
I suppose that this will have to do.
Thank you Amy ans John for your help.
I got tearing with the custom resolution.
I decided to return the NUC.
I am sorry to hear that, I sincerely apologize for any inconvenience that the product may have caused you and if there is anything else I can help you please let me know.
