Okay, so that’s why you need to use Dualink 0. I guessed before, but I thought with the Radeon card were only sold with the higher 1600x900 screen sizes.1366x768 internal screen
Ok. And one thing that when i'm using the switchresX i can change the fresh rate to 90hz with 1366x768 internal screen. But on big sur can't do this.
In that case, do you have Windows on a different partition or Linux(live Linux)?
