I bought one of these a couple weeks ago. Not only was it bigger than I expected, the quality is amazing. I have it hooked up to my Lenovo Yoga 910 through USB-C to display port cable. I didn’t calibrate or do anything and it just pops. This price is unbeatable. I shopped all kinds of monitors and this was the clear winner.
Note that this monitor does not have height/rotation adjustment. I chose the ASUS 4K monitor over the Samsung for this reason.
