Hi everyone. I have the newest iMac 27" (2019)
with the latest Mac OS (Mojave 10.14.5).
When I connect second monitor (Dell u2414h 1920x1080) all is ok while it is working. When I turn it off (Dell) then my iMac is starting lags (some little freezes every 2-3 seconds).
Connection is done using cable Type-C to HDMI.
Please help to found out what is the problem and how to fix it?
