Changing the refresh rate of the monitor

Hi!

I have a Jetson TX1 Developer Kit with L4T installed, and Im trying to change the monitor refresh rate from 60Hz to 74Hz with no success. Ive tried xrandr to modify this value, but I get the following error. Even if I set the refresh rate to 60Hz (with the same method), the same error occurs.
Could anyone help me how to change the refresh rate of the monitor, please?

What do you get from “get-edid | edid-decode” (may need packages “read-edid” and “edid-decode”)? Is 1920x1080@75Hz listed?

Thank you for your reply!

Unfortunately, I don’t have a chance to try this out right now (because I don’t have the dev kit with me), but I will definitely contact you if I get any result.

Anyway, I think the reason of the error is something different, because if I create a new mode with 60Hz, I get the same error. And 1920x1080 60.0 Hz configuration is the default configuration, so it must be supported.

Hi!

I have installed packages “edid-decode” and “read-edid”, but executing command “get-edid” got the following output.

ubuntu@tegra-ubuntu:~$ sudo get-edid
This is read-edid version 3.0.1. Prepare for some fun.
Attempting to use i2c interface

1 potential busses found: 2
Bus 2 doesn't really have an EDID...
Couldn't find an accessible EDID on this computer.
I'm sorry nothing was successful. Maybe try some other arguments
if you played with them, or send an email to Matthew Kern <pyrophobicman@gmail.com>.

This means your monitor did not reply with a query on what it is. Typically get-edid returns binary data, and then it is piped through something like parse-edid or edid-decode to put it in human readable format. If you are using an old style 15-pin D-sub connector at any point (such as an adapter), this would cause the failure. What is the exact cabling of the monitor?

Anyway, from a Windows Desktop via NVIDIA Control Panel I managed to set 1920x1080@74Hz.

Jetson TX1 connects to the monitor through a HDMI-DVI cable. (So I use the DVI-D input of the monitor)

I would think that would work, but I’m still a bit suspicious since get-edid did not find any response. What is the monitor model? Is there a URL showing its specs? Also, some DVI cables are analog only, so I’m wondering if you have other DVI cables to try.

It would also be interesting to see what get-edid shows if you were to use that monitor on your desktop using a live Ubuntu CD (no install needed, runs in RAM…if you’re feeling ambitious).

Sorry for my English…my bad.
What I meant to say is: Jetson TX1 is connected to the monitor through a HDMI-DVI cable. (So I am using the DVI-D input of the monitor).

The monitor I am currently testing is LG 23MB35, but my ultimate goal is to display (74Hz) using a DLP LightCrafter 4500 projector (which is connected to the Jetson TX1 via HDMI). I tested the projector, too, to change the refresh rate with ‘xrandr’ and also tried ‘get-edid’ command to get some info, but exactly the same errors occur. So I assume it is not a monitor related problem.

If I have no choice, I will try live Ubuntu, but I don’t see how it could help.
Is there no other way to change the refresh rate?

Is it possible to try a different HDMI-DVI cable? It wouldn’t be unusual for a cable with conversion between connector types to cause issues. The monitor itself should work fine, as the DVI-D should support EDID (the cable is the suspicious part). Seeing the cable behavior on a different Linux system would also be useful (Windows uses differet software, finding EDID from a desktop Linux system would be a very helpful test).

The main reason why a cable becomes suspicious is that if the cable were intended to work with DVI-A, then the wire for EDID could be missing…yet the cable would perhaps otherwise look similar. Although the monitor claims the connector is DVI-D, it may in fact also support mixed analog function…the monitor specs say it has a D-Sub connector supporting analog…this in turn would mean a DVI-A cable would work for video if the video source happened to work at a compatible speed/setting. Historically, cables and adapters have been found to be the issue for a number of Jetson EDID video quirks, so this would not be unusual if it is the cause.

I tested a different cable and got the same error. Even checked the DVI connector of the cable, it must be DVI-D since it has no analog pins. (http://www.amazon.com/dp/B014I8UQJY/ this description also says it is DVI-D compatible)
I think there is no problem with the cable.

Back to the beginning, the default configuration is 1920x1080@60.0Hz. If I create a “new 1920x1080_60.00 mode” with the standard method with xrandr, I got the same error. So it is neither a monitor or configuration compatible problem (because 1920x1080@60.0Hz is 100% supported).

ubuntu@tegra-ubuntu:~$ xrandr --addmode HDMI-0 1920x1080_60.00

I don’t know what it is, but it may be a Linux for Tegra or an xrandr bug/error.
Any good ideas? I am truly grateful for your help.

Which L4T release is being used? JTX1 ships with R23.1, but R23.2 fixed some video issues.

It might be interesting to see what dmesg and /var/log/Xorg.0.log changes show up upon removal and reconnect of the DVI-D cable. So basically boot up normally, try to run X11 as normal, and then unplug and re-plug the video cable (check logs before and after).

I think L4T I am using is the latest release, but will check it later.

It seems there are some errors…

That’s great, the problem may be similar to this:

https://devtalk.nvidia.com/default/topic/922873/hdmi-hot-pluggable-facing-the-error-csr_display0ab-emem-decode-error-on-pde-or-pte-entry/?offset=2

This does look related, but can you try “get-edid | parse-edid” again to see the error message? Check after a fresh reboot and no disconnect/reconnect of the monitor, and then again after disconnect/reconnect (looking for error messages, and especially differences between the two attempts before/after).

For checking L4T release version, see this output:

head -n 1 /etc/nv_tegra_release

Ok I checked it, my L4T version is R23.2.

fresh restart -> get-edid -> unplug/re-plug -> get-edid -> dmesg:

Obviously, the error message for get-edid is the same:

ubuntu@tegra-ubuntu:~$ sudo get-edid
This is read-edid version 3.0.1. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 1
No EDID on bus 3
No EDID on bus 4
No EDID on bus 5
No EDID on bus 6
1 potential busses found: 2
Bus 2 doesn't really have an EDID...
Couldn't find an accessible EDID on this computer.
I'm sorry nothing was successful. Maybe try some other arguments
if you played with them, or send an email to Matthew Kern <pyrophobicman@gmail.com>.

There is a definite failure to read EDID. The real mystery is why. Unplug/replug offers more details of the i2c failure, but i2c logs are something I am unable to debug. It seems that the gist of it is i2c from the monitor either not responding or responding in an invalid way, possibly causing other software trying to use the response to have issues.

Just to verify the nVidia-specific files are all in place, does everything show OK from:

sha1sum -c /etc/nv_tegra_release

It would be very useful to see how a desktop Linux computer responds to EDID query for that exact monitor.

The nVidia-specific files are all in place. I will check the EDID query response of a Linux computer soon.

It seems like the problem is with the i2c communicatin of tegra.
So I checked the “dmesg” of Jetson TX1 again, and found these suspicious lines I overlooked before:

...

So obviously at least one other Ubuntu system on a desktop motherboard was able to successfully read and parse the EDID.

To clarify, which machine had this dmesg log? Was it the desktop Ubuntu? If the desktop was seeing this, then it means the desktop is more gracefully handling an error…if it is the JTX1, then there are a number of possibilities.

i2c i2c-8: sendbytes: NAK bailout.

The later dmesg from JTX1 with the format of “i2c i2c-0: of_i2c: modalias failure on /i2c@7000c000/icm20628@68” looks like a firmware file issue. Basically it is referring to i2c controller physical address and a kernel feature not liking what it found. Has there been any kind of kernel change at all on the JTX1, or is it running with all of the default kernel configuration?
