Describe the bug
First of all thank you for the hard work that is put in to make this. I have installed PiKVM HDMI USB on my raspberry pi 4 and I am able to access the GUI and see my server terminal. The only issue is when I am in the Bios and select any option it just gets messy like you see in the screenshot and also shows a different language when my default language is English. Unfortunately I am unable to change the BIOS to CSM so I am unsure what I should be doing next. Any help on this would be appreciated. Thanks

Expected behavior
I expected it to show me the BIOS as I see when I connect a display to my server

Hi. I'm sorry, but there's nothing we can do here. You're using HDMI USB, which does not have the ability to configure EDID (the monitor metadata). We could make some settings for CSI bridge, but here we literally have no control over this black box.

All good I will have a look at CSI bridge option then. Thanks for your response.
