I’m looking for a way to set the advertised resolution of the KVM, this is useful in cases when installing an operating system from scratch, before drivers to set the resolution are available on the guest. An example use case is installing Almalinux or Rocky Linux on a bare metal host.
With the latest firmware the installer will show a screen with max resolution that is available, making the text and controls very small and full of artifacts on the screen capture. I would like to set the advertised resolution to 1920x1080 or 1280x720, so that the installer text and controls are readable from the Openterface QT app.
Staff: please reply here. When resolved, consider linking back on Discord to drive users to the forum.

So far OpenterfaceQT does not support setting the advertised max resolution, and we have tested write custom EDID before , but stocked at the internal checksum failure.
In theory, it should work, but need to speed more time to try and test.
I can share you a tool from MarcoSilicon to patch the custom EDID to the video capture card firmware. But you need to have the knowledge build the custom EDID and you need to reconnect everything every time you change the EDID.

Thank you @Kevin Peng , if youcan share the documentation you have and what you have do untill this point, I can take a look at it. I think that it would be a useful feature for the Openterface project both for the MiniKVM and KVMGo.
