Hello,

 

I have attempted to run a 1920 x 1080 screen but my screen just has a white/grey screen with little noise.

I modified the registers from this script: "6_1f_PortA_1080p_YPrPb_444_In_RGB_444_out_through_HDMI_VLC_16_31_32"

 

Once open, I toggle the SW switch and modified the following registers.

 

I/O (0x98)

0x00 = 02;

0x01 = 06;

0x02 = 12;

0x03 = 40;

0x05 = 28;

0x06 = A7;

0x0B = 44;

0x0C = 42;

0x14 = 7F;

0x15 = 80;

0x19 = 83;

0x33 = 40;

 

HDMI (0x68)

0x48 = 40;

 

CP (0x44)

0xBA = 01;

0xC9 = 2C;

 

Repeater (0x64)

0x40 = 81;

 

When this didn't work then I changed the IO to

0x00 = 1E;

0x01 = 05;

0x02 = 12;

...still see the same image.

Any guidance will be highly appreciated.

Thank you,

 

Melissa
