In reference manual of ADV7611, next infomation is exist. Table 6. Primary Mode and Video Standard Selection
(1) PRIM_MODE[3:0] = 0101、VID_STD[5:0] = 011110(Input Video = HD 1x1、Output Resolution = 1920 x 1080)
(2) PRIM_MODE[3:0] = 0110、VID_STD[5:0] = 000101(Input Video = SXGA、Output Resolution = 1280 x 1024 @ 60)

    Hi,

    PRIM_MODE and VID_STD are used to set up the free run modes.These controls are also used to specify the free run output standard.  You could not able to support the format which are not included in the video standard selection(VID_STD) table for free-run.

     But this format can be support by using any source equipment.

    Thanks,
