To change the screen resolution, please specify the screen-resolution parameter in the browserWSEndpoint URL.

const puppeteer = require('puppeteer-core')
const capabilities = {
    'tb:options': {
        key: process.env.TB_KEY,
        secret: process.env.TB_SECRET
    },
    browserName: 'chrome',
    browserVersion: 'latest',
    'screen-resolution': '1600x900'
}
const browser = await puppeteer.connect({
  browserWSEndpoint: `wss://cloud.testingbot.com/puppeteer?capabilities=${encodeURIComponent(JSON.stringify(capabilities))}`
})

const page = await browser.newPage()
await page.goto('https://testingbot.com')
await page.screenshot({ path: 'screenshot.png' })
browser.close()

Changing the screen resolution does not resize the viewport. To change the viewport with Puppeteer, please use page.setViewport.
