Notes:
• Computer (for example, DMT and CVT) formats set DVQM=0 for full gamut.
• DVQM can be set to 1 to test the undershoot/overshoot signal code margins (for
example, see SMPTE 296M section 7.12).
• All television formats (for example, 1080i29) set DVQM=2 for reduced gamut required
by various television standards (for example, EIA/CEA-861-B).
