[citation needed]DPMS does not define implementation details of its various power levels; [3] while in a CRT-based display the three steps could logically be mapped to three blocks to be shut down in order of increasing savings, thermal stress, and warm-up time (video amplifier, deflection, filaments) not all designs ...
Amstrad PPC512, closed Amstrad PPC640. The two computers had very similar specifications. The PPC512 had an NEC V30 [1] [3] processor running at 8 MHz, 512 KiB of memory, a full-size 102-key keyboard with a numeric keypad, a built-in liquid crystal display (not backlit) [6] that could emulate the CGA or MDA [2] and either one or two 720k 3.5" floppy drives (the model was either the PPC512S or ...

Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
MS-DOS and all versions of Windows after Windows 3.1 (Windows 95, Windows 98, Windows Me, Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10 and Windows 11) also display a black screen of death when the operating system cannot boot.
