I have an HP laptop connected to a dock that has two DP 1.4 ports. I’m connecting it to a 38″ ultrawide monitor that has a resolution of 3840×1600 up to 144Hz. Unfortunately this monitor has 1 DP port which is used by my gaming PC so I need to use an HDMI port to connect to my laptop dock. In order to run this resolution at something higher than 30Hz I needed to use a DP1.4 to HDMI 2.0B cable. The Club 3D CAC-1082 worked perfectly and gives me 74Hz which is perfect for office work. I’m trying to move my dock which will require a 7 to 10 foot extension but I need to maintain this HDMI 2.0B signal. I tried an active extension cable from Cable Matters and that did not work. Could someone recommend me a solution that will give me a ~15ft cable?
