I've instantiated a HDMI RX interface. it only can receive standard 1080P and 4K format. for a special 2K format(resolution 2560*1080), it cannot be parsed. Any different settings for this special resolution or it's just the feature?

HI,

For once, the clocking freq maybe different for different video resolution ?

• Have you try out with HDMI example design to rule out potential Quartus design issue first ?
• Does the HDMI RX get connected to other logic design insides FPGA core ? How do you rule out is it HDMI issue or other user logic issue ?

In short, you can also refer to HDMI user guide doc page 37 (table 15) for summary of different freq support for different TMDS data rate.

Thanks.
