Hi,

 

I have a Dell monitor that runs at resolution of 1440x900 at 60Hz. What should I do to modify the reference design to run the example at 1440x900?

 

At the moment, the following resolutions are supported:

 

file: cf_hdmi.h

enum videoResolution
{
    RESOLUTION_640x480,
    RESOLUTION_800x600,
    RESOLUTION_1024x768,
    RESOLUTION_1280x720,
    RESOLUTION_1360x768,
    RESOLUTION_1600x900,
    RESOLUTION_1920x1080
};

 

Is it just a matter of modifying and adding the appropriate entries here:

 

file: cf_hdmi.c

 

static const unsigned long detailedTiming[7][9] =
{
    {25180000, 640, 144, 16, 96, 480, 29, 10, 2},
    {40000000, 800, 256, 40, 128, 600, 28, 1, 4},
    {65000000, 1024, 320, 136, 24, 768, 38, 3, 6},
    {74250000, 1280, 370, 110, 40, 720, 30, 5, 5},
    {84750000, 1360, 416, 136, 72, 768, 30, 3, 5},
    {108000000, 1600, 400, 32, 48, 900, 12, 3, 6},
    {148500000, 1920, 280, 44, 88, 1080, 45, 4, 5}
};

 

Regards,
