I'm using this VGA to HDMI adapter on my System76 Thelio Astra's VGA output. It's coming out of an ASPEED BMC chip, and should be outputting a valid VGA signal (verified with my VGA monitor, at least).

But I only get the noise as above. When I move around my mouse or enter input, the noise changes, as in this gif:

I'm wondering if there are some corrections you can do on the JetKVM side to accept what may be strange different resolution settings coming out of these server BMCs. I believe the Supermicro system with the Ampere Altra Max had a similar issue that you fixed in a software update as well.
