4K Resolution: The 4K resolution (3840 x 2160 pixels) provides incredibly sharp and detailed visuals. Whether it's text, images, or videos, everything appears with remarkable clarity. In an educational setting, this allows students to clearly see fine details in scientific diagrams, historical maps, or complex mathematical formulas. For example, in a biology class, a high-resolution image of a cell structure can be displayed, enabling students to observe the various organelles with ease.
Vivid Color Reproduction: The LCD panel offers accurate and vivid color reproduction. Colors are rich and true-to-life, enhancing the visual impact of presentations and educational materials. In an art class, students can appreciate the nuances of different colors in famous paintings or their own artworks. This accurate color display is also crucial for graphic design or marketing presentations where color accuracy is essential.
