NUC8i7HVK USB Type-C two display configuration issue

I have 2 similar display Dell S2718D connected through rear USB Type-C but after wake up one of them some times (approx. 1 of 7 wake up cycles) can't determine correct resolution (screen 1, 2 and 3). It is return to normal resolution after unplug and plug monitor back or power monitor off and then on (screen 4).

For test purpose I connect one of the monitor to HDMI port and 5 days there is no issue appeared and them both works as it's should.

Hi David,

Monitors are connected directly to NUC by USB-C to USB-C cable without any kind of adapters.

Hi David,

That sad, but my issue happens again just now after 9 wake up cycle.

Also tells some additional details of my observation.

There is no link between monitor sleep time and issue occurrence. It can happens with very short sleep time less then 1 minute and also with a long sleep time if I don't power off my NUC for night.

Hello Riddle, Thank you for your response. After reviewing some information, I have found that the monitor has a driver that could assist with any possible issues you may be experiencing so my recommendation is for you to update the driver, please refer to the link below: https://www.dell.com/support/home/us/en/04/product-support/product/dell-s2718d-monitor/drivers * Please be aware that the content on that site is not controlled by Intel*.

Hello Riddle, Thank you for your response. Have you tried other monitors with the system to see if the issue is present? By other monitors I mean different brand or models. This is important so we can diagnose if the problem is with the monitor. You could also try to connect the monitors with different USB-C cables just to test.
