If you're facing the SteamVR Display connection trouble issue with your VR Device, then you should consider applying the following solutions:

V. Check the HDMI & USB cable connection to the Headset

Make sure that the Headset cable 3 pins are connected to the Computer DisplayPort, USB 3.0 Port, and Headset power adapter properly.

Try to test with different cables if available, especially the 3-in-1 cable that is connected to the VR device HDMI, USB, and adaptor ports.

It is not working even after re-plugging, Remove all the connector cables from the VR Headset.

Get an Electrical maintenance spray and apply it to the VR Device cable connector ports.

I would suggest using WD-40, Pidilite Zorrik 88, Aerol, CRC, or any similar cleaner spray as per availability in your locality.

After applying a spray, plug the connector cables into the cleaned ports and restart the SteamVR. Now, it should detect the Headset successfully.



VI. Update SteamVR to Beta build

6. Choose DisplayPort Training Mode and switch to Compatibility Mode A

It will restart the SteamVR Beta and your Headset will get connected to the Device.

You can try another Mode - Compatibility Mode B if the previous one fails.



VII. Contact Valve Support

If issues persist, submit a support ticket to Valve for personalized assistance.

Explain the specific display error 436 and the steps that you've already taken for troubleshooting. Most they will recommend you to replace the Cables.
