    Excellent Productivity Monitor!

    Big beautiful screen. I purchased this to replace a 3 monitor setup I had that was just making my space look too cluttered with all the cables. I do not miss my 3 monitor setup now that I have this. I have my work laptop connected via HDMI and personal macOS device connected to this using the thunder bolt cable. Switch between them is easy. It will automatically switch for you if one is off and the other is on. If both are on, you will have to switch it manually using the button at the bottom center of the monitor. The picture quality is great and is like having to large 4K monitors side by si

    According to my Mac System Information the display is 6400 x 2700, not 5K

    I am so impressed with the picture quality. The screen is so bright I had to dim it. Using Thunderbolt on a Mac the scrolling is so smooth. The colors look to me to fantastic, but I am not a photographer. Not cheap, but so worth every penny!
