I have a iDock C10 and have just connected a new main monitor (2560 x 1440) and first ran it at default 144hz, but it on and of suddenly makes the whole picture move all of a sudden at times which is very annoying especially when playing video games. Lowering the frequency to 60hz seem to solve the issue, but it is a bit of a shame not being able to have the highest frequency possible. The iDock has the latest firmware version (4.0) and have also tried to switch the output HDMI-cable connecting the iDock to the monitor, but did not help.
Thanks for getting back to us and truly sorry for the issue.
Recommend switch this 2560x1440P monitor conenct to the"HDMI out 2" and this channel output from the PC “HDMI in” connection which support up to 2560x1440@144Hz.
The “HDMI out 1” have a conversion from “DP in” so can only support up to 2560x1440@100Hz forsomePCs and monitors.
Kindly please check does this can solve your problem or not.
Best Regards,
