Review on Dell S2721QS Ultra Thin DisplayPort Certified Pivot Adjustment, Curved, High Dynamic Range, Tilt Adjustment, HD by Marco Liu

The monitor is excellent but the cable is of poor quality. Other reviewers have mentioned this shortcoming, which helped me fix the issue. I have a Surface laptop connected to a Microsoft Dock and dual monitors. The HDMI cable provided by Dell does not support 4K resolution. I've tried several other HDMI cables and the best resolution I could get was 1920 x 1080, well below 4K standards. Finally, I bought a DisplayPort to Mini DisplayPort cable, connected it to the docking station and a Dell monitor and instantly got a 3840 x 2160 resolution. For that reason I'm giving 4 stars for a very good monitor.
