ADV7511 DVI mode for zedboard

I have downloaded the reference design cf_adv7511_zed and built for the zedboard. It can successfully display a correct image on the Samsung LCD TV using HDMI mode on the zedboard. However, when I try to connect to the Dell monitor through HDMI-to-DVI convertor, the color displayed is not correct.

 

I have changed the register from iic_write(0x39, 0xaf, 0x06) to 0x04 and I also checked with the RTL and found the fpga hw has done color space conversion to convert the rgb->ycbcr. Thus I try to make use of the CSC feature of the ADV7511 to correct the color but I've tried to calculate the inverse matrix based on the CSC matrix found in the RTL but none of the try is successful.

 

Could anyone provide me the correct programming register values to display image on a DVI-mode Full HD monitor? Thanks!
