Frequently Asked Questions

Your screen resolution describes the width and height of your display in pixels. Whats My Reso shows the screen dimensions reported by your browser, helping you understand the measurements associated with your current display.

Open Whats My Reso in your browser. The screen checker automatically displays supported screen dimensions and related information without requiring you to download software.

1920 × 1080 means a display format with 1,920 horizontal pixels and 1,080 vertical pixels. This resolution is commonly called Full HD.

These terms describe common display resolution formats. HD is commonly 1280 × 720, Full HD is 1920 × 1080, QHD is 2560 × 1440, and 4K UHD is 3840 × 2160.

Not necessarily. Higher resolution can provide more detail, but visual quality also depends on screen size, pixel density, panel quality, viewing distance, and scaling.

You can check the display specifications in your operating system or manufacturer documentation. Browser-reported screen dimensions can provide useful clues, but they may not reveal the physical pixel resolution accurately when scaling is applied.

Browser viewport size is the width and height of the area available for webpage content inside your browser window. It can be smaller than the overall screen dimensions.

Screen resolution refers to display dimensions, while viewport size refers to the available webpage viewing area. Resizing a browser window can change its viewport size without changing the display resolution.

Device Pixel Ratio describes the relationship between physical display pixels and CSS pixels, as reported by the browser. It helps explain how logical web dimensions map to the physical display.

Many high-density displays and scaled desktop configurations use multiple physical pixels for a CSS pixel. Browser zoom and operating-system scaling can also influence the reported DPR.

Screen orientation indicates whether the display is currently being used in portrait or landscape orientation. Browser support and platform behavior can affect how orientation is reported.

Color depth is browser-reported information about the number of bits used to represent pixel colors. It does not necessarily describe the full color gamut or every capability of the display panel.

Operating-system scaling, browser zoom, and device pixel ratio can affect browser-reported screen dimensions. These values may differ from your monitor's physical pixel specifications.

Your browser viewport changes when you resize its window. The screen's physical resolution normally stays the same, even though the area available to the webpage becomes larger or smaller.

Mobile browsers often report logical CSS pixel dimensions rather than the physical pixel count advertised for the device's display. Device pixel ratio helps explain this difference.

The viewport measures the webpage's available viewing area. Browser controls, window dimensions, and other interface elements can reduce that area relative to the screen dimensions.

Unexpected measurements can result from display scaling, zoom, browser differences, orientation changes, or device-specific behavior. Compare the results with your system display settings and try reloading the page.

No. Standard browser APIs do not reliably reveal the exact physical pixel resolution of every monitor, especially with display scaling or multi-monitor setups.

Whats My Reso is a browser-based screen resolution checker that helps visitors view screen dimensions and related display information in an easy-to-understand format.

The tool uses browser-provided information to display supported screen and viewport measurements. These values are presented in an organized interface for quick reference.

No. The screen resolution checker works directly in a compatible web browser without requiring additional software installation.

Yes. The website is designed for compatible desktop, tablet, and smartphone browsers. Available measurements may vary by device and browser.

The homepage checker provides a copy feature for supported resolution values, making it easier to save or share the dimensions.

No. Whats My Reso is an informational checker. It displays browser-reported measurements and does not change your operating system's display settings.

Yes. The existing screen resolution checker on the homepage is free to use without requiring account registration.

No. You can access the free screen checker without creating an account.

A Pro offering is being considered for advanced reporting and productivity features. Availability, features, and pricing have not yet been finalized.

Pro concepts include downloadable display reports, saved measurement history, structured data exports, and device comparison tools. These are proposed capabilities and are not currently advertised as available.

Yes. Businesses and teams can contact Whats My Reso to discuss potential custom requirements. Any solution depends on technical feasibility, scope, and agreement.
