How to set max viewport in Puppeteer?

Question

When I run a new page, I must specify size of the viewport using the setViewport function:

await page.setViewport({
    width: 1920,
    height: 108

For me the combination of defaultViewport: null and args: ['--start-maximized'] gave me fullscreen with view fitting to screensize so:

browser = await puppeteer.launch({
            headless: false,
            args: [
                '--start-maximized',
            ],
            defaultViewport: null,
        });
