Speaking of mobile development, something that&#x27;s been annoying me for a long time is that while you can &quot;emulate&quot; the devicePixelRatio of a mobile device, it doesn&#x27;t actually seem to do anything meaningful.<p>For example, my phone has a resolution of 1080x1920 and a dPR of 3, so the viewport size is 360x640.<p>If I set these properties in Chrome Dev Tools, I just get a 360x640 rendering out of it. I&#x27;d like to be able to get a proper 1080x1920 rendition of the device screen too! It doesn&#x27;t matter that it will look absolutely enormous on my desktop screen, I just want to make sure that my code and styling actually works like I want on it. I really shouldn&#x27;t need to use an actual device for something as simple as this.
