Hi,

I have nearly one year old Acer Swift 3 (SF314-512-51DJ) and from the purchasing it I have problem with connection to monitor Dell P2423DE using USB-C cable (Power Delivery - PD). I

tried two the same type monitors, both behave the same - image is shown for 1-2 sec on notebooks (sometimes on monitor) and then dissappears, doing this constantly.

I have another notebooks HP (450 G9, 455 G10) with PD and connection is not a problem, but with my Acer yes. Today I bought another monitor Dell U2421E also with PD and my Acer doesn't have problem to connect to it with USB-C cable, it works correctly (!). But I need connect my Acer to the old one monitor Dell P2423DE… :-(.

I tried to solve this issue with local service, they changed motherboard in my Acer, but it didn't help. I have updated drivers. Now I am connected to monitor with HDMI and power adapter and it works properly.
