[afishpro]

playwright version:1.9.2
Google Chrome (or Microsoft Edge(89.0.774.57(64))) version: 89.0.4389.90(64)
python --version:3.8.8

code show as below：

from playwright.sync_api import sync_playwright

# url = r"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"
with sync_playwright() as p:
    brower = p.chromium.launch(executable_path=r"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe",
                               headless=False, args=["--incognito", "--start-in-incognito",
                                                     "--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36",
                                                     "--log-level=3", '--no-sandbox',
                                                     "--disable-infobars", "--enable-automation=False",
                                                     "--disable-blink-features=AutomationControlled",
                                                     "--window-size = '1920,1080'", "--start-maximized"])
    # "--auto-open-devtools-for-tabs=True","--window-size = "1920,1080"])
    # brower = p.chromium.launch(url)
    page = brower.new_page(viewport={'width': 1920, 'height': 1080})

as shown below:

i set the --start-maximized attribute, but it doesn’t work

You are still setting the viewport when creating page. Try passing no_viewport=True instead to explicitly tell Playwright to just go with the window size.

no_viewport
page = brower.new_page( no_viewport=True)
thank you very much for your answers, this solved my problem
