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

macOS users please note that this monitor will force you to switch to YPbPr mode when connected via HDMI. In order for the device to recognize RGB correctly, you must connect via Display Port. When connected via DisplayPort, you cannot scale the display without the display flickering. The default scaling for a 27" monitor is 1920 x 1080. This monitor does not support macOS through the Dell Display Manager software. Maybe a $45 USB-C to DisplayPort adapter could solve this problem, but I haven't decided yet. ----Overall Rating: This is a decent true 4K monitor for the price until you realize the essentials are missing. This monitor has no additional connections. No USB-C, no USB-A/B. Nothing at all. You get 2 HDMI ports, 1 display port and an audio jack, and that's it. The stand wobbles slightly from side to side when touched, making the product feel qualitatively much cheaper than it would otherwise be.
