There is no any monitors can achieve 100% brightness consistency

Achieving 100% brightness consistency across an entire monitor display is incredibly difficult, if not practically impossible, with current display technologies.

There are a few key reasons why perfect brightness uniformity is so challenging:

1. Inherent Limitations of LCD Panels:

   • Liquid crystal displays (LCDs) rely on a backlight system to illuminate the entire panel.
   • Maintaining perfectly even light distribution across the entire surface area is extremely complex due to the physics involved.
   •  

2. Manufacturing Tolerances:

   • Even high-quality monitors have minor variations in the manufacturing process that can lead to slight brightness differences.
   • Components like the backlight, polarizers, and liquid crystal layers can have tiny imperfections.
   •  

3. Viewing Angle Dependence:

   • The brightness of an LCD panel is often dependent on the viewing angle.
   • Areas near the edges and corners of the screen typically appear slightly dimmer when viewed straight-on.
   •  

4. Thermal Variations:

   • The temperature of the backlight and other components can impact brightness uniformity over time.
   • Heat buildup in certain areas can cause localized brightness changes.

While advanced monitor technologies and calibration efforts can minimize these issues, a 100% perfect brightness consistency across the entire display area is considered an unattainable goal with current display manufacturing capabilities
