After Refresh Rate switch sometimes Signal Errors with crazy Image distortion. I first thought that its a HDMI Cable Problem. I switched that but no luck, after that i thougt my HDMI Splitter is broken but atm i think its the Chromebox.
if it works without the splitter/switch inline, then I don't think the problem is with the Chromebox...

A reminder that this is a Panther box.
Should I just return to the stock firmware backup that was working previously? It appears that steamos (not that i'm loving that interface..but it's what's loaded) brewmaster has support for non uefi.
thoughts?
you can revert to the previous legacy boot/SeaBIOS firmware using the Firmware Utility Script, just choose the unlock option (u) from the main menu first, then it will give you the choice between Legacy and UEFI when flashing. No reason to go back to stock. I'm not expecting it will fix the issue, but worth trying to rule it out at least
