Both are just locked to maximum and changing either is through the one button on the bottom. I don't use this button often, but it is annoying that I can't just use the brightness button on my keyboard to bring the brightness of the monitor down considering the monitor is just suposed to be displaying the mac exactly how it would look if I was just looking at the mac!!! same thing with volume. But you can't, you have to use the poorly designed one button on the bottom of the monitor. I was excited at first because I figured this app would make it possible for me to change volume and displays settings through the mac. Any other button in the app that you should be able to click on, doesn't work. All it does is open the displays page in settings. However, when I was messing around trying to find the ways to maximize the use of the screen I stumble upon probably the dumbest app ever to exist. Only one cord into my mac, which is just dandy. The USB-C connection charges my computer as well so I can have the lid closed and use a USB-ethernet on the back of the monitor for better internet. I stumbled upon that monitor and it has quite a few functions which is awesome! I have my Mac, a Wii, and a PS3 all connect at once and just need to switch inputs to change.

To disable Zoom, simply triple-click on the side button again.I have an LG UHD Ultra Fine 4K monitor that I really wanted to use for my MacBook air to have a bigger screen. If you tap the controller, you can hide it. A small floating circle will appear on your screen, indicating that Zoom is currently turned on.

When Zoom is enabled, your phone will automatically add the low light filter to your display, making it darker, even if your brightness is already at its lowest. If you'd like, you can toggle on the Zoom feature here, but the easier way is to triple-click the side button from anywhere on your phone to use Zoom. Launch the Settings application and go to Accessibility > Zoom and make sure that the Low Light option is chosen under Zoom Filter. Using the Zoom accessibility feature, you can add a low light filter over your display to make it darker than usual. If you're only interested in dropping the brightness, and don't want warmer colors or less intense colors, there is a way to lower just the display brightness.

This adjusts the intensity of bright colors on your display.
