Yes. You can set alarms for weekdays, weekends, or daily. Stopwatch and countdown are included.

Is the brightness adjustable?

Four levels of brightness plus an auto light-sensor for night use.

Any buzzing noise?

No. It uses a modern drive strategy with temperature compensation, ensuring long lifespan without ghosting or burn-in.

What kind of power source should I use?

Please use a USB power source of 5V / 0.5A or above. Avoid low-quality fast chargers or outlets shared with fast-charging devices to prevent damage.
