Thanks for that info Terry. I'm just talking about general desktop usage, and it's nice to know I can use hdmi since my dp port is used.
This might be a stupid question but I just want to make sure. I'm using my dp port to connect to my 4k TV, it runs 4k at 30hz. If I'm using that 4k display AND the 1440p one at the same time will that reduce the max hz of the 1440p display? I'm planning on getting a 75hz 1440p monitor so anything above 75hz I don't really care about losing.
