NUC5i5MYHE don't recognize automatically my LG 4K TV.

Hello there,

i got a new NUC5i5MYHE with 2x mini DP Ports, i connected one to my Samsung SMS27A850 Display and the other one to my LG 49UB820V TV.

i use this adapter http://www.amazon.de/gp/product/B0130CBIR8?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00

and this Cable http://www.amazon.de/gp/product/B00T7UG8OQ?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00

to connect it to LG TV.

everything works fine except  that when i start my nuc its don't recognize automatically my TV, i have to plug the DP adapter out of my nuc and plug it back (when the nuc is running) so and only so its regonize my TV !!!

its not a Solution for me ! i cant do that everyday!

i tried another Display with Hdmi input and i used different Cables  but i got exactly the same problem -> display will be only regonized when i plug the DP adapter out and back.

any idea why? and how to fix that?

thanks a lot.

PS. i use Windows 10 64b and all Drivers and Bios are uptodate.
