Firmware archive for an X.VISION XL2220AIH, packed as a small 135 KB RAR. The name gives only the model and no board number or version, but the model reads like a monitor, so the contents are likely a scaler or EEPROM dump. Technicians reflash such images with a programmer such as a CH341A when a display shows no picture, boot-loops or has a corrupted menu. Check the chip marking and its capacity against the image before writing, and read and save the original contents first so you can restore them if the dump turns out not to suit your revision.
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 @biosarchive. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
