Clokwork Sharing here the same comment I posted in response to one of your other contributions because it is relevant and important here as well:
FRC is more common than not based on my research.
AI says: "While many consumer-grade OLED monitors claim to support 10-bit color, most actually achieve this through 8-bit + Frame Rate Control (FRC), a technique that simulates a wider color range by rapidly switching between colors. True 10-bit OLED panels, which can display a full billion colors without FRC, are typically found in higher-end professional monitors."
"Yes, most LCD monitors, especially those targeting the consumer market, utilize Frame Rate Control (FRC) to simulate a wider color gamut, effectively making 8-bit panels behave like 10-bit panels. FRC achieves this by rapidly alternating between different color shades within a single pixel, giving the illusion of more colors than the panel can natively display."
You can imagine this rapid flickering is problematic for many eyes and brains.
Would we not vastly prefer true 6 bit or true 8 bit or true 10 bit color without any FRC?
Of course, but we aren't given the choice.
