Small 83.2 KB RAR archive labelled for non-HD panels at 1366x768 resolution, with no device or board named. It most likely holds a firmware or panel configuration file meant to pair a main board with a 1366x768 display, often alongside a Full HD counterpart. Technicians use such files when swapping panels or repairing TV and monitor boards that show a distorted or blank image. Because the name is uninformative, check the contents and target board carefully, and back up the existing chip before writing anything.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @gunvantrathore. Enginerys does not host this file.
