The NanoVNA-H4 uses DAC output dimming, so the brightness can be adjusted using DAC commands. Dac_value = 800 is the minimum brightness, dac_value = 3300 is the maximum brightness, you can enter any number between 800-3300 for brightness adjustment.

Note: 1800 is the default, out-of-box, NanoVNA-H4 mid-range brightness setting. I always wondered about the purpose of the "dac" console command, although on the 2.8" NanoVNA-H's it's use is evidently reserved for other (future?) purposes.
