Make sure the sync wire is going to the correct pin on the UCS19V chassis (it should be the composite sync input).
If your board outputs negative composite sync, confirm the chassis is set for negative CSYNC and not H/V separate.
Also verify you’ve got video ground tied properly missing video ground can cause weird image wrap like this.
If you want, I can walk you through how to identify exactly which sync the board is sending and how to hook it to the EYGO chassis properly.
