Thanks, I managed to upgrade to LE but it was the Krypton build so I reverted back to OE and I couldn't find a LE for Jarvis 16.1.

It's confirmed now that the Chromebox, on boot, sends an unsupported (PC) resolution, and if it's booted while that HMDI isn't on screen it often results in a black screen and needs power cycling while the TV is set to view the Chromebox HMDI source. It did this on my last TV, I used to note that if I powered up the Chromebox (usually was on 24/7) before turning the TV on, I'd need to reboot it again to get anything on screen.

So, any idea how I can stop it sending unsupported / PC resolutions on boot, or how I can upgrade to LE 16.1 if this also fixes the issue on boot?

I've ran this set up for years but with this recent issue since buying a new TV I'm starting to look for a 'set top box' solution as it's very frustrating if I need to reboot for any reason I pretty much have to bring a PC monitor into the living room to get it running!

Thanks in advance
