The HP 24 Envy uses a new variant of the Almost Glossy or Low Haze coating the HP 25-27 CW/er/es/XW monitors use, and the 24 Envy has a thinner fake-frame-less casing which they named a four sided micro-edge frame. The HP 24 Envy has a short stand which only tilts, Displayport, HDMI and USB-C. It natively supports 75hz, as well as AMD Free-Sync (requires compatible AMD graphics card) and comes with a VESA stand adapter.
The Dell S2418H and S2718H also use the same border-less casing/bezel;
