How to adjust the DSI dispaly offset

This post was flagged by the community and is temporarily hidden.

The parameters are all the in panel device tree. Try to adjust them first.

I reset the value for ‘vfront-porch’ ,the vertical direction is normal now.
I’ve tried to modify the value for ’ hfront-porch’ and ’ hback-porch’ ,but there is no change in the horizontal direction display.
Where else can it be affected?

                            display-timings {
                                    1200x1920-32-60Hz {
                                            clock-frequency = <193224000>;
                                            hactive = <1200>;
                                            vactive = <1920>;
                                           hfront-porch = <107>;
                                           hback-porch = <20>;
                                            hsync-len = <1>;


                                            vfront-porch = <120>;
                                            vback-porch = <7>;

                                            vsync-len = <1>;
                                            nvidia,h-ref-to-sync = <1>;
                                            nvidia,v-ref-to-sync = <11>;
                                    };
                            };
