Hello, I have exchanged the connections - one NUC from HDMI to USB-C and the other from USB-C to HDMI. The problem persists. I have not yet bought a new USB-C-to-DP-Cable and, unfortunately, don't have another one at hand - only tons of DP and HDMI-Cables. I have bought an active HDMI-2.1-to-DP1.4-Connector, but only got a display output of it intermittently. I strongly suspect that the problem is my monitor. At the moment I am unwilling to buy a new one, since it supports 4k at 120hz and has four display connectors. Buying a new monitor with these features would cost me most likely more than 1k. My current one was a bargain at 800 Euros.
