Hi! Does anyone know how to turn down the brightness on the monitor?

The brightness settings of the monitor could be changed using the menu button at the bottom of the monitor. The detailed instructions are available in the user manual of the monitor, available online.

Is there a vesa mount adapter that works with this monitor? I'm having a difficult time finding one that says it's compatible with this model.

We recommend you to reach out to the Dell sales support team for assistance in choosing the correct VESA Mount Adapter. They are available at 1-800-456-3355.

What is the difference between the s2421h the s2421hs?

Haven't bought it, but from what I can gather, the the 21HS has a HDMI + DisplayPort while the 21H has two HDMI's. Possibly other differences as well but that's AFAIK.

Does the power cable have Power Supply Brick Cord? Or is it just a standard cord without a power supply attached? Need to know before buying.

Dell S2421HS offers standard Power cable without brick (varies by country). Please reach out to the Amazon sales support team for further information and purchase assistance.
