Description: Controls how lines are doubled and interlaced modes are handled Example: double2 Type: choice

Value: none (Single / Single)

Value: double (Double / Double Frames) value: double2 (Double / Double Fields) Value: double3 (Double / Double Fields+)

Value: scanlines (Scanlines / Double Frames) Value: scanlines2 (Scanlines / Double Fields) Value: scanlines3 (Scanlines / Double Fields+)

Value: scanlines2p (Double Fields / Double Frames) value: scanlines2p2 (Double Fields / Double Fields) Value: scanlines2p3 (Double Fields / Double Fields+)

Value: scanlines3p (Double Fields+ / Double Frames) Value: scanlines3p2 (Double Fields+ / Double Fields) Value: scanlines3p3 (Double Fields+ / Double Fields+)

Single: Non-interlaced lines are not doubled.

Double: Non-interlaced lines are doubled in height.

Scanlines: Black lines are inserted between each non-interlaced lines.

Double Frames: Odd and even field pairs are combined to single frame, display update rate becomes effectively halved (50Hz -> 25Hz).

Double Fields: Odd and even fields are shown alternately. When odd field is shown, previous even field is not changed or erased and vice versa.

Double Fields+: Same as above but instead of not changing previous field, previous field is blanked. Sort of emulates really really short persistence CRT display.
