The ETM0700G0DH6 Datasheet lists 2 lines as the typical vsync pulse width, 525 lines as the vertical period, and 35 lines as the vsync -de time, which is vsync len + back porch. So vertical timings 480 + 10 + 2 + 33 = 525 should be valid for the ET0700G0DH6 panel: https://www.glynshop.com/erp/owweb/Daten/DSS/EDT/Products/Specifications/Active%20Displays/ET0700G0DH6.pdf et070080dh6 I have not seen the data sheet for ET070080DH6. regards Philipp
