-## About the display
-
-- Resolution: 352x160=56,320 pixels
-- Pixels are grouped into 44x20=880 tiles (8x8=64 pixels each)
-- Smallest addressable unit: row of pixels inside of a tile (8 pixels = 1 byte)
-- The brightness can only be set per tile
-- Screen content can be changed using a simple UDP protocol
-- Between each row of tiles, there is a gap of around 4 pixels size. This gap changes the aspect ratio of the display.
-
-### Binary format
-
-A UDP package sent to the display has a header size of 10 bytes.
-Each header value has a size of two bytes (unsigned 16 bit integer).
-Depending on the command, there can be a payload following the header.
-
-The commands are implemented in DisplayCommands.
-
-To change screen contents, these commands are the most relevant:
-
-1. Clear screen
-    - command: `0x0002`
-    - (rest does not matter)
-2. Send CP437 data: render specified text into rectangular region
-    - command: `0x0003`
-    - top left tile x
-    - top left tile y
-    - width in tiles
-    - height in tiles
-    - payload: (width in tiles * height in tiles) bytes
-        - 1 byte = 1 character
-        - each character is rendered into one tile (mono-spaced)
-        - characters are encoded using code page 437
-3. Send bitmap window: set pixel states for a rectangular region
-    - command: `0x0013`
-    - top left tile x
-    - top left _pixel_ y
-    - width in tiles
-    - height in _pixels_
-    - payload: (width in tiles * height in pixels) bytes
-        - network byte order
-        - 1 bit = 1 pixel
-
-There are other commands implemented as well, e.g. for changing the brightness.

 ## What happened to servicepoint2?
 
 After `servicepoint2` has been merged into `servicepoint`, `servicepoint2` will not continue to get any updates.
