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
Instead of loading Legacy (1) I reloaded my full backup firmware and all display ports (DP & HDMI) and all cables play nice (enough) with all displays once again. I didn't go back to stock, the box had been running your script with openelec/chromeos dual boot for a long time already, just back to the legacy version that worked previously and now once again. I stuck with GalliomOS this time, since it was what I was live booting off of. But the revert back to the working version enabled dp and hdmi (mirroring) while Gallium was still on the stick, which it wouldn't do under the UEFI, so that you know.
