I had one, Dell's UP2414Q. It was a piece of shit, mostly due to requiring multi-stream transport to run in 60 hz mode. So you'd get a GPU driver or OS update and the screen would stop working. Sometimes the panel would split in half and one of them would black out or shift its content sideways so there was a seam in the middle and a piece of the edge wrapped around to the center. Would not recommend.

The ones afterward that got rid of the MST requirement might've been better. Pixel density was great.
