Hi

 

I want to output DVI with ADV7511W.

So I am trying to do this at the EVAL board.

Q1)

At the Programming guide, to chose DVI, 0xAF[1] = 1'b0 must be chosen.

Is this the only different thing between HDMI and DVI?

 

Q2)

I tried to output DVI with  EVAL-ADV7612-7511.

I am using Astro VA-876 for the image source.

The monitor is Astro VA-1831l.

And the image data is VESA 1280*960 60Hz.

After I run the script "6_1f_Port_A_1080p_YPrPb_444_in_RGB_444_out_Through_HDMI_Fast_Switching_VIC_16_31_32.py"

which I attached , I changed 0xAF[1].

But sometime when I set 0xAF[1]=1'b0 the color looks strange.

Why this happens?

Is there anything else to set the registor?

 

↓0xAF[1] = 1'b1 HDMI mode

 

↓0xAF[1]=1'b0 NG DVI mode

 

↓0xAF[1]=1'b0 OK DVI mode

 

Best regards.

Kawa
