ADV7511W - width setting

Hi EZ,

 

I have a question about width setting for the ADV7511W device.

 

I have seen that when changing the register 0x37 and 0x38 the width can be actively changed. Normally for 720p these registers should be set to 0xA00 (0x37[4:0] 0x38[7:1] = 1280), but I can see that if I use 720p and I instead change these registers to, lets say, 1300 the horizontal width gets shrunk a bit. This is an interesting feature for my project.

 

I would like to know exactly what is happening here, if this is recommended or not and if this will have any impact on certain monitors etc.

 

Regards,

StaringL
