Frame rate
Frame rate is optional. If no frame rate is given, then the frame rates are assumed.
• 24 = 24 Hz
• 60 = 60 Hz
Common component TV formats
• 480pLH Component SDTV signal containing letterboxed 16x9 high-definition content
• 480pSH Component SDTV signal containing anamorphically under-sampled 16x9

Computer display format names
Computer display formats are assumed to use progressive scanning. In computer format
naming, the first three characters indicate the vendor ID using the EISA ID (for example,
IBM, SUN, VSC) or the display type, the next two characters indicate the approximate
horizontal resolution, the next two digits indicate the frame rate (which will be half the field
rate with interlace scanning), and the final character designates the aperture (used only
when the aperture is not A).
Example
Vendor ID (EISA)
• SMT for VESA (digital) Safe Mode Timing
• DMT for VESA Standard Discrete Monitor Timing
• GTF for VESA Generalized Timing Format standard
• CEA for Consumer Electronics Association
• EIA for Electronics Industries Association (CEA)
Approximate horizontal resolution examples
• 02 for 256 pixels
• 09 for 960 pixels
• 12 for 1200 pixels
• 30 for 3072 pixels
