I would welcome a response to this too - I already understand Chrome is at 1080p for now.
My concern is that Stadia seems to be either 1080p or 4K - and nothing in between.
Its fine for my CCU, as I have a 4K TV - but my PC monitor is a High Refresh Rate G-sync Monitor that goes to 1440p only.
So, is the plan for Stadia through Chrome to be *either* 1080p or 4K ... and nothing in between?
I fear so - when I put my CCU into my monitor it sticks to 1080p and, well, is pretty hideous tbh.
