Conditional filters in config.txt - Raspberry Pi Documentation
When a single SD card (or card image) is being used with one Pi and one monitor, it is easy to set config.txt as required for that specific combination and keep it that way, amending it only when something changes.

However, if one Pi is swapped between different monitors, or if the SD card (or card image) is being swapped between multiple Pis, a single set of settings may no longer be sufficient. Conditional filters allow you to define certain sections of the config file to be used only in specific cases, allowing a single config.txt to create different configurations when read by different hardware.

Subpixel layout - Lagom LCD test
Each pixel on an LCD screen consists of three subpixels: red, green, and blue (RGB), that are sitting next to each other. Most operating systems since about 2003 can improve the quality of on-screen text by using these subpixels. However, this only works if the operating system knows how the subpixels are arranged. For the majority of the monitors, the arrangement is RGB (red on the left, green in the middle, and blue on the right). However, on an occasional monitor, it is the other way around (BGR). And if you orient your monitor in portrait mode, the subpixel layout can be V-RGB (vertical RGB) or V-BGR.
