}

CVT support parameters decoded from a display range limits descriptor (0xFD).

Used when TimingFormula::Cvt is active (byte 10 = 0x04).

Fields

version: u8

CVT standard version, encoded as two BCD nibbles (e.g., 0x11 = version 1.1).

pixel_clock_adjust: u8

Additional pixel clock precision: 6-bit value from byte 12 bits 7–2.

The maximum pixel clock is: (descriptor byte 9 × 10 MHz) − (pixel_clock_adjust × 0.25 MHz). When all six bits are set (63), byte 9 was already rounded up to the nearest 10 MHz.

max_h_active_pixels: Option<u16>

Maximum number of horizontal active pixels, or None if there is no limit.

Computed as 8 × (byte 13 + 256 × (byte 12 bits 1–0)). None when the 10-bit combined value is zero.

supported_aspect_ratios: CvtAspectRatios

Aspect ratios the display supports for CVT-generated timings.

preferred_aspect_ratio: Option<CvtAspectRatio>

Preferred aspect ratio for CVT-generated timings, or None for a reserved value.

standard_blanking: bool

Standard CVT blanking (normal blanking) is supported.

reduced_blanking: bool

Reduced CVT blanking is supported (preferred over standard blanking).

scaling: CvtScaling

Display scaling capabilities.

preferred_v_rate: Option<u8>

Preferred vertical refresh rate in Hz, or None if byte 17 = 0x00 (reserved).
