My apologies if I offended you.
Yes, it does not surprise me if it led me to a number of dead requests in various forums on similar things
However the Displays Forum works very well. Several library authors frequent this specific Forum. And they can generally sort you out when they can identify your hardware.
Displays vary greatly. Very few have controllers that are visible to the human eye. Ebay sellers often provide erroneous information. However we can generally find what we need from a link. (especially if there is a pcb view)
