VESA and Industry Standards and Guidelines
for Computer Display Monitor Timing (DMT)
Version 1.0, Revision 11
May 1, 2007
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.

1. DMT Standards and Guidelines Summary
Table 1-1 contains a summary of display monitor timings (DMT) that are defined in this standard. All
DMTs listed in Table 1-1 are non-interlaced video timing modes - unless otherwise specified using the
symbol “(Int.)”. The symbol “(Int.)” means that this DMT is interlaced. All DMTs listed in Table 1-1
include normal video blanking - unless otherwise specified using the symbol “(RB)”. The symbol “(RB)”
means that this DMT includes Reduced Blanking. Reduced Blanking timings can only be generated using
the Coordinated Video Timing (CVT) Formula. Complete timing specifications for these DMTs are defined
in section 7.
