I have flashed and updated 5 new Raspberry Pi 4s for a TM display. When I configure them through tournament manager the only thing that happens when I click save display settings is that the name of the display will show up under the IP address but the display won’t ever leave the IP screen. I am using Windows. I am not sure what the problem might be. I saw a thread on the forum already, but they did not have an answer. Thanks for your help!

This could be the new TM update, but I might be wrong. Can you link the other thread about this problem?
I was the one with the other issue. It turned out to be that Lanschool was installed on the machine. Once that was removed, it worked fine. You may have some other issue, but TM needs to listen to port 5000 on the machine. If anything else is using that port, you could have issues. Try to close down everything you can to see if you can get it to work, or use networking tools to see if anything is using that port.
I am not an expert, so everything I said could be quite wrong! But I hope it points you in the right direction.
I had a different issue on a different computer. The school’s policy is different depending on if the device is on the school network or on a private network. While you could just try to disable the firewall, it’s best to just allow the vex applications directly.
This will give you a list and then you can find the VEX programs and let them through. If you can’t do it this is what your IT people may need to do. But it’s common for school computers to have additional policies in place to protect the school’s equipment.
Thank you, everyone, for your help.
I ended up allowing access through the Firewall and it fixed the problem.
Thanks!

Hi Everyone,
I’m having the same problem at a school - I can see the IP address on the R.Pi display, but can’t get it to show anything else. It seems all of the firewall settings are allowed (see screenshot). Is there another app that should be there?
Is there anything else I can ask my school board IT guy? He’s coming to help me tomorrow to troubleshoot.
Thanks!
- Are you sure that the TM computer and RPi are on the same network? What is the IP address of the TM and what is the IP address of the RPi Display?
- Did you reimage the RPi with the newest TM RPi Image?
- Can you get to the RPi via a web browser and the IP address displayed on the RPi?
- Can you try turning off the firewall altogether on the TM Computer?
Thanks for your reply.
I was unable to resolve the problem, but I’ll include how far I got in case anyone else has a similar issue (and I’ll post later if I am able to find a resolution).
I was able to get the TM computer and RPi on the same network. Using the ethernet, I was able to have the display working and showing the Pit Display. When I was able to connect to the RPi wifi settings and input the wifi SSID and password, I connected and was able to change the Display Name, but nothing else would show up (even after waiting 10 minutes).
Everything is up to date.
I’m unable to turn off the firewall completely - since I’m in a school on a board managed device.
The school board network administrator even came and played around a bit. He mentioned that being on an Enterprise Network might be the problem (as mentioned in https://roboticseducation.org/documents/2018/12/vex-tm-raspberry-pi-wifi-support-beta.pdf/) . This is outside of my technical expertise.
He said he’ll take the problem back to his team and see if they can establish a work-around.
Using ethernet wires would work, but not what we’re hoping for. I might stick with a few laptops on wifi tucked in behind displays.
