Frequently Asked Questions

Screen resolution testing refers to testing or validating the appearance of websites across numerous devices (desktops, tablets, mobiles) having different screen resolutions. It helps ensure that web pages render accurately and viewers get an optimized browsing experience when they access websites from different device-browser combinations. 

Screen resolution testing of a website requires monitoring website appearance on multiple real devices (mobile and desktop). However, it is not feasible for all individual QAs or teams to set up an extensive device lab just to perform screen resolution testing. 

 An easy way to address this challenge is to use a cloud-based testing tool like BrowserStack’s Responsive Checker. Simply enter the URL of their website under test into the address bar and click on Check. The tool will instantly load the website across multiple real and latest devices(iPhone X, Galaxy Note 10, iPad pro, Windows, Mac OSX) with varied screen resolutions – 375×812, 412×869, 1280×1024, and more

 For comprehensive screen resolution testing, use BrowserStack Live. Its real device cloud provides teams with 2000+ real devices & browsers. Simply sign up for a free trial or opt for a suitable plan and start with screen resolution testing on desired device-browser combinations. No complex setup involved. Testers can also interact with web elements and perform scroll and pinch or zoom operations to mimic end-user activity in the real world. 

Testing website resolution on emulators or simulators is not as effective in delivering accurate results compared to testing on real devices. This is because emulators and simulators are software programs that mimic the functionality of real devices up to a great extent. However, they can not match the performance of an actual device as there are binary translations involved while using them that make them slower. 

Moreover, finding and installing emulators for every device, particularly the ones that are recently launched is extremely difficult. Given this, it is better to opt for a tool that offers real devices for instant testing.

Listed below are key advantages of performing screen resolution testing on real devices: 

  1. Instantly test website in different screen sizes
  2. Discover visual bugs for specific resolutions faster
  3. Gain accurate test results every time

The responsive tool helps testers instantly view a website across different device types (smartphones, tablets, desktops) with distinct screen resolutions. Users simply need to enter the URL, and the tool immediately loads the website across the available device screens. 

 Users can also scroll the entire website on the desired device from the available devices. Additionally, they can also view their websites in Portrait and Landscape mode.
