Update February 2022: Please note that sidebar brightness can be adjusted by touching the very edge of the sidebar bezel. Like most, I haven't read the instructions, but stumbled across it by accident. I tried another company's side monitor and it didn't work and felt flimsy, but this one is sturdy and stays firmly on my laptop screen. Feels much more durable. Very satisfied and highly recommended!
