Responsive design is the key to making your site reach a better audience in the world of modern internet. It is a fact that more than 60 percent of users access websites via smartphones and tablets, so your design needs to adapt to their screen resolutions and sizes. It is no secret that most front-end developers are used to working with mobile resolutions these days.

But when it comes to desktop and laptop resolutions, things tend to get a bit complicated lately. It is not the issue with standard monitor resolutions like 1366×768 pixels and 1400×900 pixels. The issue arises when increasing the resolution to 1080p (1920×1080 pixels) and beyond.

Modern desktops and laptops are equipped with powerful graphic cards like ATI Radeon R9, Nvidia GTX 1070, Intel 5600 and above and with IPS or WLED screens capable of rendering awesome native resolutions.

These resolutions were initially targeted towards powerful gaming machines like Alienware, Asus ROG, MSI Dominator and Phantom series and others, but today, they are pretty common. Most modern laptops and desktops deliver 1080p resolutions and start delivering 4K and even 5K resolutions lately.

This is where a front-end developer’s job gets a bit complicated. The design must be thoroughly tested on these resolutions, to make sure every feature is functional and rendered correctly. Not everyone has the device to test these resolutions.

This is where emulators come in handy. Internet Explorer, Mozilla Firefox and Chrome have built-in emulators that can be used up to a certain resolutions. Moreover, there are online services and plugins that can help do the job. You should use them, to make sure the design is flawless.
