Other Parts Discussed in Thread: DS90UB949-Q1, ALP
HI, I have a DS90UB949-Q1 EVAL Board connected to a display that contains the DS90UB948 deserializer. This display has a dual twisted-pair input.
I have been able to use the ALP GUI to generate test patterns in 1920x1080p at 60 hz refresh rate.
These look good.
My intention is to run HDMI from my laptop into the 949 then generate the LVDS signals into the display. However, that link is not working. Although the laptop recognizes the Eval Board as a display at 1920x1080 resolution. The information screen on the ALP software indicates that the Eval Board is recognizing the display's deserializer.
It looks like the 949 can communicate with the display and the laptop, but there is a connection between HDMI and LVDS that is missing...
Can you point me in a direction to start looking for the correct setup? I'm using the default settings on the Eval Board.
