Check for Secondary Display Modes
Test signal : 1.) 640*350 @ 70.09/85.08Hz
2.) 640*480 @ 72.81/75.00/85.01Hz
3.) 720*400 @ 70.08/85.04Hz
4.) 800*600 @ 56.25/60.32/72.19/75.00/85.06Hz
5.) 832*624 @ 74.55Hz
6.) 1024*768 @ 43.48/60.00/70.00/75.03/85.00Hz
Normally when the primary mode 800*600 @ 85Hz is well adjusted and complaint with the specification,
then the secondary display modes will be great possibility to be complaint with the specification. But we
still have to check with general test pattern to make sure every secondary modes is complaint with
specification.
