I’ve been trying to connect a couple of different high-resolution DisplayPort displays to the AGX Orin devkit, but it does not seem to support the highest resolution modes exposed by the displays. The module documentation states that the AGX Orin supports DisplayPort 1.4a, 4 lanes, and HBR3, which should be sufficient.
Is this a known limitation? If so, is this planned to be fixed in a future release?
Here’s the EDID of the 5k monitor that isn’t fully supported: the native mode is 5120x2880@60, DP 1.4 HBR3, no DSC. The Orin was only able to enumerate the lower-res modes (up to 3840x2160@60). This monitor works fine in the highest resolution 5120x2880@60 mode connected to the Quadro P2000 in my development host machine (Ubuntu 20.04.4, kernel 5.4.0, nvidia driver 510.73.05)

I also tried a VR HMD: an HP Reverb G1, native resolution 4320x2160@90. For this display, only the lower-res 2880x1440 modes are available. Again, this device works fine in the highest resolution 4320x2160@90 mode on the Quadro P2000 in my desktop.
