We have designed our carried board and changed the hardware to HDMI. It can work fine in most displays, including some 4K displays. But three 4K displays can not work. The test result is below:
ASUS VG289Q:
It can not detect 4K resolution, and the display did not work, but it can work fine if we directly change the resolution to full HD.
Thanks for your reply.
Unfortunately, I could not find any NX series with HDMI ports in my company. All of them are DP ports. Could I use other series, for example, TX2 or AGX Xavier?
Hi WayneWWW,
I finally got a Xavier NX devkit Carried board + Orin NX 16G module. I tested the display ASUS VG289Q, which could detect and show the screen. But I found the resolution is 1920x1080, which is not correct. Our display is 4K resolution. I tried three displays of 4K resolution, which still showed 1920x1080.
I think the situation is different in our case. Our board can work well in some 4K displays; the 4K resolution is correct. But it could not detect any signal if we connected the display ASUS VG289Q.
The way you flashed your xavier nx devkit board is not correct. When you saw your xrandr gives “DP-x” but not “HDMI-x”, you need to know that it is still in DP mode. DP mode cannot work HDMI well.
Please use the p3509 board config in your Linux_for_Tegra to flash your board. There should be something like p3509-a02-xxxx-p3767-xxx.conf.
