Review on Samsung S27R650FDN Business DisplayPort Monitor - 1920X1080P, 75Hz, Anti-Glare Coating, Frameless, Wall Mountable, Flicker-Free by Mark Hussain

I bought this particular monitor to replace my 24 inch ASUS monitor. Looks great, but I found it expensive. I was hoping it would come with built-in speakers, but unfortunately it didn't. I knew about it, but compared to all other monitors on a best day, this one stood out. The main feature I was looking for was the height adjustment. The info says HDMI is 60Hz and the optimal mode is 60Hz but advertised as 75Hz. I had to manually change it to 75Hz in the Macbook Pro but the monitor still shows 60Hz which I don't understand. I thought the PIVOT function would work automatically, but unfortunately it doesn't. I have a Macbook Pro connected to a monitor via HDMI. I had to manually change the 90 degree rotation in System Preferences -> Display to display content on the monitor at 90 degrees. It has 4 USB ports (2 USB 2.0 ports) and (2 USB 3.0 ports). Unfortunately, the USB dongle that came with the keyboard and monitor doesn't work when I plug it into either one. I believe they are not suitable for version 2.0 and 3.0. Overall, I give 4 stars for the optics.
