Describe the bug
Hello,
I have some Issues in the UEFI BIOS in the HP Elitebook 640 G9. The Stream is glitchy (Screenshot below) and mouse and keyboard dont work. I am not sure how to solve this Problem.

To Reproduce
Steps to reproduce the behavior, like:

Plug in the Laptop via HDMI
Open the BIOS settings
Close the Laptop so the Screen gets streamed to HDMI Output.
Open PiKVM Stream

Expected behavior
I would have expected that the Keyboard and mouse work.

Screenshots

Hello! For faster support, please contact our Discord chat: https://discord.gg/bpmXfz5
Meanwhile, here some tips:

For the stream, you can try to tune EDID: https://docs.pikvm.org/edid
For the KB/Mouse - do you see the keyboard/mouse icon on the top right corner of the web ui? Is it orange?

You can answer here, but I recommend duplicating your question and diagnostic answers in the chat. Our support will help you.

Hello
I tried EDID Examples from the site and after that it worked perfectly.
I used the EDID from the V2+ with the 1280x1024 resolution.

Thank you very much!
