Hi
I use DL-3500 to make the USB-DVI adapter. DVI connect to the monitor. The descriptor data in the EDID data of the display is not defined by the display name data block, and the DL3500 chip can not read the EDID data from the display.
However, the monitor directly connected to the PC display card through the DVI cable, the display card can be read to the display of the EDID data.
EDID BYTES:
