I have a TDS 2024 which uses the KCS057QV1AJ-G39 display. If there's a sticker on the back specifying its protocol, then it's new to me. Where would the number be? Interestingly, all the TDS 1000/2000 use have compatible displays according to the service manuals, but the 2000C has an additional display adapter board uses the same interface. Very weird!
