Part Number: DLPC6421
I met a problem in my project dual DLPC6421 + FPGA + DLP470TP.
The image working fine with 4K/60Hz video input source.
When I enable the keystone function and setup the angle, the image become abnormal with many extra horizonal lines.
It can be recovered when the keystone angle go back to zero.
It would be appreciated if anyone can give me some hint to fix it.
Thank you.
