I recently started to use Dex with external HDMI display, and it ocurrs randomly that the external display lost signal briefly from my Dex phone (S23 Ultra) from time to time. I have researched this issue online, and see a lot of other people complaining about the same issue, but there has never been a solution to the problem. Anyone has any insights? Please don't suggest changing cables or hubs - they're all good. I suspect this is something internal within the S23 Ultra and with other models as well.
