Review on Dell S2721HS 27-Inch Adjustable Response FreeSync Monitor with 1920X1080 Resolution, Swivel Adjustment, Anti-Glare Screen, and HDMI Connectivity by Dave Wheeler

Would rate it 5 stars barring one quirk that seems to haunt Dell monitors like this. Mine is connected to my laptop via HDMI via a hub. After logging out and shutting down my laptop, if I don't also turn off the monitor, it goes into sleep mode. When I turn the laptop back on, the monitor claims no HDMI device is connected. I get the same message when I turn the monitor off and then back on. The only workaround is to either disconnect and then reconnect the HDMI cable, or ensure the monitor is off when the laptop boots up. This second method only works sporadically. I've checked several forums around the web and this seems to be an ongoing problem with no clear solution.
