A smart display is genuinely useful on a bedside table until the first night, when you discover it is lighting the room. Every one of these devices has the settings needed to fix it, and none of them are configured sensibly out of the box.
The short answer
Turn on the night or sleep mode, which dims the screen below what the ordinary brightness slider allows, and set a schedule so it activates automatically. Then switch the screensaver from a photo slideshow to a dark clock, because a rotating gallery of bright holiday photos is what actually lights the room. Both settings are usually separate and both matter.
Why the brightness slider is not enough
The standard brightness control has a floor, and on most smart displays that floor is still clearly visible in a dark bedroom. Night mode is a separate feature that goes below it, often switching to white or amber text on a black background and reducing the backlight further than the slider permits.
The screensaver is the other half of the problem, and the bigger one. A display showing a dark clock face emits very little light. The same display cycling through a photo album is effectively a lamp, and it changes brightness every thirty seconds as the pictures change, which is worse than a constant glow.
Enable night mode and schedule it
Find night mode, sleep mode or do not disturb in the display settings. Turn it on and set a schedule matching your sleeping hours, so you are not doing it manually every evening.
Change the screensaver to a dark clock
Switch from photo frame or ambient gallery to a clock, and choose a dark or minimal clock face if several are offered. This makes more difference than any brightness setting.
Turn off or dim the always-on display
Some devices offer a fully off screen when idle, waking on voice or touch. If that option exists, it is the best answer for a bedroom. If not, the dimmest clock face is the fallback.
Enable the ambient light sensor if it has one
Most of these devices can adapt to room light, but the feature is sometimes off by default or set to a minimum that is still too bright. Enable it and check the minimum level separately.
Silence notification chimes overnight
Do not forget the audio side. A notification sound at two in the morning is worse than the light. Check what is allowed through during your scheduled quiet hours.
Turn off the camera indicator or cover it if it bothers you
Some displays have a bright indicator LED. Most have a physical camera shutter, which is worth using in a bedroom regardless of brightness. A small piece of electrical tape handles a stubborn LED.
Check that the alarm still works with night mode on
Test it. A do not disturb setting that also silences alarms is a nasty surprise to discover on a work morning.
Move it off the bedside table if none of this is enough
Some displays simply do not go dim enough. Across the room on a chest of drawers is far less intrusive and still within voice range.
Set the night schedule to start earlier than you go to bed, around an hour before. The point of dimming is not only while you are asleep; a bright screen in the hour before bed is the part that affects how easily you drop off.
Other things that glow
While you are dealing with this, the same bedroom usually has several other offenders worth addressing at the same time:
- Television standby lights. A small piece of dark electrical tape, or a standby LED setting in the menu.
- Router and mesh node lights. Most routers have a setting to turn the lights off on a schedule. Remember you have done it, because a router with no lights is harder to diagnose later.
- Charging indicators. Some chargers and power strips have surprisingly bright LEDs.
- Smart plug indicators. Usually small, occasionally not. Check before putting one behind a bedside lamp.
- Air purifiers and humidifiers. Many have a display dimming or off option buried in a button combination.
Do not cover ventilation slots when taping over an LED. It sounds obvious, and people do it, particularly on routers and set-top boxes where the indicator sits next to a vent.
Choosing one for a bedroom
If you are buying rather than fixing, the features that matter for bedside use are a genuine screen-off idle mode rather than just a dim one, a physical camera shutter, a physical microphone mute switch, and a sensible alarm implementation with a gradual wake option. Screen size matters less than you would think; a smaller display is easier to live with at close range and emits less light by simple physics.
Why is my smart display still bright on the lowest setting?
The standard brightness slider has a floor. Night or sleep mode is a separate feature that goes below it. Enable that rather than relying on the slider.
Does the screensaver setting really matter?
More than the brightness setting. A photo slideshow emits far more light than a dark clock face, and it changes constantly, which is more disruptive than a steady glow.
Will night mode stop my alarm?
It should not, but test it. Some do not disturb configurations silence alarms, and discovering that on a work morning is an unpleasant way to find out.
Can I turn the screen off completely?
On some models, yes, with the display waking on voice or touch. Check for that option first, because it is the best answer for a bedroom if it exists.
Should I cover the camera?
Most smart displays have a physical shutter, and using it in a bedroom is sensible regardless of the brightness question. A physical shutter is more reliable than a software setting.
The bottom line
Enable night mode on a schedule and switch the screensaver to a dark clock, because those two together fix nearly all of it. Check that alarms still sound with night mode active, and deal with the other LEDs in the room while you are at it. If the display still lights the room at its dimmest, move it off the bedside table.
