Most LED monitors flicker at low brightness settings, but you can get ones that don't.

The ones that don't have more expensive electronics driving the backlight. Eizo's FlexScan EV series is one example.

I have a FlexScan EV, and I don't find being able to turn the brightness down to 1 or 2 nits without any flicker as useful as I thought I would. Even in complete darkness, it is hard to read the screen when the brightness is that low.

You info is dated. 95% of monitors on the market have zero flicker at any brightness. All LG and Acer monitors are for example are all like that.
