/* README - MASKS GUIDE
|
|
||||||
|
|
||||||
To obtain the best results with masks 0, 1, 3, 4:
|
|
||||||
must leave “mask size” at 1 and the display must be set to its native resolution to result in evenly spaced “active” LCD subpixels.
|
|
||||||
|
|
||||||
Mask 0: Uses a magenta and green pattern for even spacing of the LCD subpixels.
|
|
||||||
|
|
||||||
Mask 1: Intended for displays that have RBG subpixels (as opposed to the more common RGB).
|
|
||||||
Uses a yellow/blue pattern for even spacing of the LCD subpixels.
|
|
||||||
|
|
||||||
Mask 2: Common red/green/blue pattern.
|
|
||||||
|
|
||||||
Mask 3: This is useful for 4K displays, where masks 0 and 1 can look too fine.
|
|
||||||
Uses a red/yellow/cyan/blue pattern to result in even spacing of the LCD subpixels.
|
|
||||||
|
|
||||||
Mask 4: Intended for displays that have the less common RBG subpixel pattern.
|
|
||||||
This is useful for 4K displays, where masks 0 and 1 can look too fine.
|
|
||||||
Uses a red/magenta/cyan/green pattern for even spacing of the LCD subpixels.

/* README - MASKS GUIDE
|
||||||
|
|
||||||
|
To obtain the best results with masks 0, 1, 3, 4:
|
||||||
|
must leave “mask size” at 1 and the display must be set to its native resolution to result in evenly spaced “active” LCD subpixels.
|
||||||
|
|
||||||
|
Mask 0: Uses a magenta and green pattern for even spacing of the LCD subpixels.
|
||||||
|
|
||||||
|
Mask 1: Similar to Mask 0, but with "ZigZag"
|
||||||
|
|
||||||
|
Mask 2: Intended for displays that have RBG subpixels (as opposed to the more common RGB).
|
||||||
|
Uses a yellow/blue pattern for even spacing of the LCD subpixels.
|
||||||
|
|
||||||
|
Mask 3: Common red/green/blue pattern.
|
||||||
|
|
||||||
|
Mask 4: This is useful for 4K displays, where masks 0 and 1 can look too fine.
|
||||||
|
Uses a red/yellow/cyan/blue pattern to result in even spacing of the LCD subpixels.
|
||||||
|
|
||||||
|
Mask 5: Intended for displays that have the less common RBG subpixel pattern.
|
||||||
|
This is useful for 4K displays, where masks 0 and 1 can look too fine.
|
||||||
|
Uses a red/magenta/cyan/green pattern for even spacing of the LCD subpixels.
