Proposed VESA and Industry Standards and Guidelines

for Computer Display Monitor Timing (DMT)

Version 1.0, Revision 12p, Draft 3

10/17/08

This document includes all current VESA Monitor Timing Standards & Guidelines.

'Guidelines' are subjected to the same VESA review and approval process as 'Standards', but

are designated as 'Guidelines' to ease concerns on the part of some VESA members that VESA

is 'endorsing' these timing standards. 'Guidelines' designations are typically used for lower

resolutions or lower refresh rates that are in common industry use in lower-performance

systems. For reference, this document also includes a number of industry standard timings (de-

facto standards) for the computer industry

This document is the primary means of distribution for all VESA Monitor Timing Standards

and Guidelines. The standards and guidelines covered by this document are outlined on the

following page.
