Review on Dell UltraSharp U2720Q 4K Backlit Monitor with Anti-Glare Screen, Pivot & Tilt Adjustment, USB Hub, HD, HDMI, LED (DELU2720Q) by Jay Hart

I liked the monitor and thought it was great. The picture is just fantastic. Then I had serious problems with it lagging behind my laptop screen when using the Dell Connect Wi-Fi Stream app. So I connected HDMI and there was no picture at all. I've spent hours troubleshooting and can't get any of the features to work. Same HDMI cable and same laptop works fine on my old Dell TV. I haven't contacted Dell support yet, I'm sure there is a solution.
