I bought a new Dell U2720Q monitor yesterday. The monitor look great but I got a problem with USB Type-C connection. Sometime the monitor got disconnected automatically and reconnect again after that. It usually happen when a new window is open or close. Here are videos 1 and 2.
My machine is a laptop running non-supported Ubuntu 20.04, GTX 1650 running latest Nvidia driver. I also notice that the problem also happened when I was opening a game in Windows, usually when I open a game, Assassin's Creed Odyssey to be specific. * What Windows PC model? * What operating system? * What GPU? * Does it happen in any other game on the Windows PC?

It seem like there is a bug with PD implementation because when I connect the laptop charging cable, that does not happen. The U2720Q/U2720QM USB Type-C power delivery only provides up to 90W. What is the wattage of the supplied power AC adapter on the Windows PC laptop? Dell-Admin
I found this post on reddit which might related. That thread specifically deals with the U3419W and U3818DW which use the older Ti TPS6598E power delivery chip. Dell-Admin
