8-Bit vs 10-Bit & FRC Dithering Banding Tester
Inspect monitor color depth, discover if your panel uses 8-bit + FRC (Frame Rate Control) temporal dithering, and identify harsh color banding steps across dark gradients.
8-bit yields 256 steps per RGB channel (16.7 million colors); 10-bit provides 1024 steps (1.07 billion colors).
Look closely at dark regions. If you see distinct vertical stripes or jumping stairs, the panel is truncating shades.
FRC alternates subpixels rapidly between two adjacent colors. On cheap panels, this appears as subtle shimmering crawl.
๐ฌ Understanding True 10-Bit vs 8-Bit + FRC Dithering
Display manufacturers often label gaming monitors as "10-Bit Color (1.07 Billion Colors)" in marketing materials when the panel is physically an 8-bit + FRC (Frame Rate Control) panel.
True Native 10-Bit
The panel's column drivers physically output 1,024 discrete voltage levels per subpixel. High-contrast gradients transition with zero visual steps or temporal noise. Common in professional OLEDs and high-end mastering monitors.
8-Bit + FRC (Spatial-Temporal Dithering)
The panel can only output 256 physical levels. To simulate intermediate shades, the panel firmware rapidly alternates pixels between adjacent brightness levels each refresh frame. While generally imperceptible at high refresh rates (144Hz+), it can cause microscopic shimmering in low-light shadows.
