I’m on Pixel betas, not Graphene, I can set resolution under Connected devices, it lists my second screen and list of resolutions. It got a little worse with the last 2 betas, I had quite good looking output, my screen is 1920x1280 instead of 1080p, it began to be stretched, as it offers only 1920x1080, or 1280x720 and something even smaller. Hopefully it will get fixed. But this is my special problem with my weird resolution screen.
