Then adjust brightness and text settings; add a sunshade or glare filter only if those steps are not enough. Shade also helps limit heat exposure to the device.
1. Move into shade and change the screen angle
Reflected sunlight and other bright light sources make screen content harder to distinguish. If possible, work in open shade rather than direct sun. Position yourself so the sun is behind you, then angle the display to keep direct sunlight from reflecting toward your eyes.

For a desk or outdoor workstation, place the screen at right angles to the strongest light source where practical. OSHA also suggests tilting a desktop monitor slightly downward to reduce reflections from overhead lighting. These positioning principles are useful outdoors, too, though OSHA’s guidance addresses workplace conditions rather than setting an outdoor-specific standard. OSHA workstation environment guidance, Lenovo monitor guidance, and Microsoft’s bright-environment tips recommend shade or careful screen positioning.
2. Raise brightness for the conditions
When daylight washes out the image, increase display brightness until text and controls are easier to see. Microsoft’s Windows 11-focused guidance notes that adaptive brightness may not be enough in bright sunlight, so a manual adjustment can help. Brightness needs vary with the light and device; maximum brightness is not a universal all-day setting. Microsoft’s guidance for using a laptop in a bright environment explains the adjustment.

3. Make text and contrast easier to read
You can improve legibility without buying an accessory. In Windows 11, try a Contrast theme and increase text size or display scaling. Larger text can be easier to read at a glance, while scaling makes interface elements larger. OSHA also notes that dark characters on a light background are less affected by reflections than light characters on a dark background. Microsoft’s Windows 11 guidance and OSHA’s workstation guidance cover these approaches.
4. Clean the display carefully
Dust can contribute to glare. OSHA advises: “Clean the monitor frequently. A layer of dust can contribute to glare.” Follow the device maker’s instructions for cleaning, since the sources do not establish a single safe method for every display or coating. OSHA Computer Workstations eTools

5. Consider a sunshade or glare filter if needed
If shade, positioning, and settings are not enough, a laptop sunshade can cast a shadow over the screen. A matte anti-glare protector or monitor glare filter may reduce reflections, but it cannot be assumed to eliminate glare. Lenovo cautions that filters can affect image clarity, and OSHA says they should not significantly decrease visibility. Try environmental changes first, then weigh the accessory’s visibility trade-off.

6. Keep the device out of direct sun when possible
Shade is useful for equipment care as well as readability. Microsoft notes that laptop use in sunlight can cause overheating. ASUS warns that high temperatures and direct sunlight can accelerate aging of monitor components and the screen. No safe temperature threshold is established in these sources, so follow the device maker’s operating guidance rather than assuming a particular outdoor temperature is safe. Microsoft and ASUS monitor care guidance.
Do not peel a built-in anti-reflective or anti-glare coating to try to improve visibility. ASUS warns that it is a functional layer and that damage can prevent the screen from displaying correctly. ASUS monitor care guidance.

What to know about device-specific outdoor features
Some products advertise anti-reflection or adaptive visibility features, but those claims apply to specific models and should not be treated as proof that a screen will be readable in every outdoor condition. Samsung says the Galaxy Tab S10 series has anti-reflection technology and claims a reflection rate under 2%; that is a Samsung manufacturer claim, not an independently validated comparison. Samsung Gulf’s Galaxy Tab S10 visibility information.

There is no universal brightness threshold or established best laptop or tablet for direct-sun readability in the sources cited here. When comparing devices, consider screen brightness and adaptive behavior, screen reflectivity, portability, battery needs, and the limits on operating in heat. Treat manufacturer visibility claims as specific to the models they describe.
