I have two CHG70 monitors, initially the displayport was working on both the monitors but now its not working at all on both monitors, but HDMI is working fine. I purchased new cables, still it didn't work. I updated the firmware to the latest, still no use. I changed the eco saving plus set to off, still didnt work. I am using the Dell docking station k16a, that has a Displayport, USB C and HDMI. Both the monitor uses auto detect of HDMI/Displayport. Monitor 1, I pluged in both HDMI cable and Displayport cable respectively. Monitor 2 HDMI cable is pluged in and both connected to the dock (monitor 1 was displaying using HDMI instead of Displayport),but the monitor 2 didnt work, once I removed the displayport cable from monitor 1, monitor 2 started working. Please advise what is the issue and how to make the displayport to work on both monitors?
Solved! Go to Solution.
HDMI on Monitor 1 and DisplayPort on Monitor 2, since it's not working on monitor 2 (DisplayPort didn't work on Monitor 1 too) both monitors now have HDMI, one on each and both are working using HDMI.
