When a computer is connected to two monitors, why does running case switch between the two monitors to open the page?

Is it possible to fix a certain monitor to open the page under test?

This thread is trying to answer question "Why does the browser switch between two monitors when opening a page with Playwright, and can a specific monitor be set to open the page?"

Playwright does not control where to open it

@skorp32: So which browser is opened is random behavior?

No, it's not random behavior. The Playwright browser behavior is determined by the configuration in the playwright.config.ts file

Hi @optional518 , as far as I understand, you want to control /on which display/ the browser will open.

Which Playwright browser(s) are you using?

What is the current behavior? Does the same browser (Chromium) open on a different display each time? Or do different browsers (Chromium vs Firefox vs Webkit) open on a different display?

I don't think Playwright has any options to control this behavior. I expect this to be browser or operating system behavior. On Mac OS, be sure to check/adjust what is your Main display. https://www.eizoglobal.com/support/compatibility/monitor/multimonitor/macos-monterey/
