I have a digital clock which adjusts its brightness automatically based on the brightness in the room. There is no way to turn this feature off. If the clock is on can I enter the room or open/close the blinds in the room on Shabbos if it will make the clock brighter/dimmer? Is it problematic to have this clock on in the first place on Shabbos?

Horav Shlomo Miller’s Shlit’a opinion is that one should indeed not use this type of clock on Shabbos.
