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.
