I updated to 1011 as well and it is still a problem. I am returning the monitor for a refund. It's a real shame given how awesome it is, but for the price, I cannot accept a non-functioning port that I would prefer to use.
I can definitely understand your concern here. Let's try to alleviate some of the stress by trying this link: https://www.samsung.com/us/support/troubleshooting/TSG01110761/ If this does not help I recommend letting a service technician have a look. As we would like to gather additional information, and look at this from a case by case basis please provide the full model code and serial number of the device as well as your best contact phone number, name, and email.
