It's a fantastic deal for a 4K monitor when I bought it last year, but it's developed a high pitched whine when viewing at 4K. Bad power components or something.

And it's Samsung, which is a name I have grown to like and has taken over my house after my ViewSonics died off one by one (bad power supplies)

Samsung service was very helpful and mentioned that there had been increased incidence in power adapter failures with the recent batch of this model that happened to be the one Amazon promoted for Prime Day.

Was able to leverage a printer power adapter to get monitor working for the time being

The useless, misleading extra power cord.4

I had a hard time with it on my first day, due to a completely irrelevant and unusable power cord being included with the assorted cords and adapters

The picture looks amazing like expected, and it's great with backwards compatibility for 1080 P
