Conventional monitors display how many bits?

• A. 12 bits
• B. 6 bits
• C. 10 bits
• D. 8 bits

Answer: (D)

Color depth governs how many distinct brightness levels a display can show for each color. Conventional monitors use 8 bits for each color channel (red, green, and blue), which gives 256 levels per channel and about 16.7 million possible colors in total. This depth strikes a practical balance: it provides smooth gradients and broad compatibility with content and graphics pipelines, without needing extreme bandwidth or storage. Higher-end displays can support 10-bit or 12-bit channels to reduce color banding and support HDR, but they require compatible content and hardware. Some cheaper or older displays used 6-bit channels with dithering, which can introduce subtle banding. So the standard option is 8 bits per color channel.
