Gray Screen

Plan a useful session with Gray Screen

Gray Screen works best when you start with one question. Decide what you need to view, compare, create, record, or demonstrate. Keep the first run at the default state. Change one control after you understand the starting result. This approach gives you a clear baseline and a useful reason for every adjustment.

Choose standard gray or measured percentage levels to reveal tint, banding, retention, and uneven luminance. Use the normal page view to prepare the settings. Enter fullscreen only after you review the exit control. Write down the mode and key values when you need to repeat the result on another device.

Choose controls by outcome

The available modes include 50 gray, 25 gray, 75 gray. The control set includes fullscreen, brightness, temperature, wake lock, quick download, keyboard, reset. Start with the option closest to your task. Avoid changing every value at once. A single change gives you a direct before-and-after comparison and makes a saved result easier to explain.

• Reveal color tint in nominally neutral areas. Set a clear finish point before you begin.
• Inspect general panel uniformity. Set a clear finish point before you begin.
• Use a neutral visual background. Set a clear finish point before you begin.

Run a repeatable workflow

1. Stage 1. Choose a mode or preset. Record the starting environment and state.
2. Stage 2. Start the embedded view, then enter fullscreen when ready. Keep the first comparison short and controlled.
3. Stage 3. Use the visible controls in the normal view; press Escape to leave fullscreen. Reset the page when the session ends.

For a device comparison, use the same browser family, viewport, room light, physical brightness, and viewing distance where practical. Run the same order on both devices. Change one environmental factor only after the matched pass is complete. Keep this route focused on this use: Reveal color tint in nominally neutral areas.

Keep a useful record

A useful record names the page, mode, control values, browser, device, viewport, date, and viewing condition. For a visual observation, describe the location and the fields where the effect appears. For a generated asset, record dimensions, format, color values, and the downloaded file name. For a simulation, record the duration, custom text, disclosure, and exit method. The starting reference for this page is 50 gray.

• For near-black OLED levels, use the dedicated OLED Gray Screen Test.

Avoid common setup errors

• For this use, do not treat a browser view as a hardware measurement or system action: Reveal color tint in nominally neutral areas.
• Do not change several settings before you record the baseline. Begin with 50 gray.
• Do not rely on a phone photograph as the only evidence. Keep this route limit in view: For near-black OLED levels, use the dedicated OLED Gray Screen Test.
• Do not leave route features active after the task ends. The main controls include fullscreen, brightness, temperature, wake lock.
• Do not add private data, credentials, payment details, or confidential text. Keep the second listed use in scope: Inspect general panel uniformity.

Continue with the closest comparison

Open a related route when the first page reveals a new question. Keep the same environment and repeat only the part needed for comparison. The closest listed routes are OLED Gray Screen Test, Screen Uniformity Test, Monitor Test. Keep this final use in mind: Use a neutral visual background.

• OLED Gray Screen Test. Near-black gray levels for inspecting OLED banding, tint, uniformity, and image retention.
• Screen Uniformity Test. Inspect luminance, tint, dirty-screen effect, and edge variation with controlled fields and grids.
• Monitor Test. A complete guided sequence for pixels, levels, gradients, sharpness, geometry, and motion.
