Rated 5 out of
Great image and a very nice stand.Bought this because the screen of my 15” Laptop was difficult for 85 year old eyes. The image is incredible and it is si much easier to use and read on this fantastic monitor. The stand is sturdy and versatile, the monitor itself is flawless from edge to edge and at 3840x2260 the images are beautiful. The only problem I have is the headphone connector isn’t great and it causes sound to go in and out.

Dual Monitors from
Crisp, Clear, CleanWhite backing looks crisp and clean and the screen is crisp as can be. I was concerned that having dual 27" monitors would be too much screen, but I was wrong. The dual setup is simply fantastic. I was able to quickly overlook the on-monitor options/settings button. It's about picture quality, and that's what I got here. I recommend.

The monitor cannot work with my laptop(Macbook Pro). My laptop can recognize the monitor and behave the same as if the monitor worked. But on the monitor side, it shows "No Signal" anyway, no matter which cable I am using. Is there anyway to solve this?
