Understanding Your Screen Resolution

This tool instantly detects your monitor's current display settings. The big blue numbers above represent your Screen Resolution (Width x Height in pixels). Knowing this number is critical for gaming performance, graphic design, and troubleshooting display issues.

What do the other numbers mean?

Pixel Ratio (DPR): This measures pixel density. If you see "2.0x" or higher, you are likely using a Retina Display (Mac) or a high-end smartphone. These screens pack more pixels into the same physical space for sharper text.
Color Depth: Most modern screens are 24-bit (True Color). If you are a professional photographer or editor using a 10-bit HDR monitor, you might see "30-bit" here.
Viewport: This is the actual "usable" area inside your browser window. It is almost always smaller than your full screen resolution because of scrollbars, toolbars, and browser borders.

⚡ IS YOUR MONITOR FAST ENOUGH?

Having a high resolution (4K) is great for visuals, but it can kill your speed in competitive games. Make sure your full setup is balanced:

Check your Hz: Is your monitor actually running at 144Hz or is it stuck at 60Hz? Test it now with our Monitor Refresh Rate Checker.
Test your Aim: A slow mouse sensor can ruin your accuracy. Verify your sensor speed with the Mouse Polling Rate Test.
Check your Keys: Ensure your keyboard isn't "ghosting" during complex combos with the Keyboard Ghosting Tester.

Does Resolution affect FPS in Gaming?

Yes, significantly. The higher your resolution, the harder your graphics card (GPU) has to work.

1080p (1920x1080): The standard for competitive gaming (CS2, Valorant). Offers the highest FPS.
1440p (2K): The sweet spot. Good balance between sharp visuals and performance.
2160p (4K): Extremely demanding. Requires a top-tier GPU to maintain 60 FPS, often introducing input lag.

If you are experiencing lag or stuttering in games, try lowering your game resolution to match a standard format like 1920x1080.
