Hello, sorry for my bad english
I have the problem that i have no picture, after i start my Intel NUC NUC6CAYH with my Samsung tv. I use a HDMI 2.0 cabel. On the NUC is Windows 10 64 Bit, with the latest drivers, and the actually bios. The samsung tv are not seeing the nuc after the start. If i start the NUC, without a HDMI cabel and put the cabel after the start in the NUC, I have a connection. On my Samsung tv is the actually driver.
On my old tv or other monitor, i don,t have the problems with the NUC.
Reading your TV manual, I understand that you have connected your NUC with HDMI cable to one of the HDMI inputs on so called One Connect Box.
If you have connected for example to HDMI 2 input, while powering on your NUC, please press HOME button on the TV remote control and then select HDMI 2 input as a video source.
