Start chromedriver on another screen with maximized window

Question

I want to start the chromedriver my second screen, but in a maximized window. Currently, I'm doing this after already the driver has already been initialized:

driver.Manage().Window.Position = Screen.AllScreens[myDisplayNumber].Bounds.Location;
driver.Manage().Window.Maximize();

But while I'm fixing the error mentioned here, I am now using the ChromeOptions to set the window maximized. To start the browser on my other screen, I tried the '--window-position'-argument. The thing is, it just doesn't work in combination with the '--start-maximized' argument. The browser starts on the specified window position on my second screen, but the window is not maximized. If I delete the '--window-position'-argument, then the browser starts maximized on my primary screen. One interesting thing is, if I replace '--start-maximized' with '--start-fullscreen', it works. I get the fullscreen-mode on my second screen. Why is this not working with '--start-maximized'?

This is how I specify the options and start the driver :

var options = new ChromeOptions();
options.PageLoadStrategy = PageLoadStrategy.None;
var windowPosition = $"--window-position=1600,-500";
options.AddArguments(
    windowPosition,
    "--start-maximized", 
    //"--start-fullscreen",
    "--enable-automation", 
    "--no-sandbox",
    "--disable-dev-shm-usage", 
    "--disable-browser-side-navigation", 
    "--disable-gpu"
    );
       
options.AddAdditionalOption(CapabilityType.AcceptInsecureCertificates, true);
options.AddUserProfilePreference("download.default_directory", Directory.GetCurrentDirectory());
var driverService = ChromeDriverService.CreateDefaultService();

return new ChromeDriver(driverService, options, TimeSpan.FromSeconds(30));
