Screen Test Pro — Introduction

Screen Test Pro is a quick, privacy-focused tool that runs right in your browser to check your display quality and device performance. No downloads, no accounts—just open it up and go. It's built as a simple static site that works smoothly on any device, from desktops to phones.

What you can do

• Pixel Test: Switch to full-screen solid colors to hunt down dead, stuck, or hot pixels. Use easy keyboard shortcuts or taps to flip through and inspect every inch of your screen.
• Performance Test: Run a fun particle animation benchmark that stresses your CPU and GPU, then get a straightforward score with simple breakdowns.
• Device Specs: Pull up key details like screen resolution, pixel density, color depth, available memory, and other basics in a snap.
• Test Pattern Cards: Check out our collection of classic test patterns to evaluate color accuracy, brightness, and more on your display. We've got three right now: EBU Colour Bars (100/0/75/0 Colour Bars), PM5544 (a common PAL test pattern), and SMPTE Color Bars (a standard NTSC test pattern).

FAQs

Do you collect any user data?
Nope, we don't collect a thing—not your data, not even device info. It's all handled right in your browser, keeping things super private and secure.

Why might my performance score vary?
Scores can change based on stuff like which browser you're using, your OS version, or if other apps or games are running in the background. It's normal for results to fluctuate a bit.

How accurate are these online tests?
No online tool, including ours, can give a perfectly accurate read on your device's real-world performance—they're all just for reference. Real benchmarks depend on way more factors.

I love the animations in the performance test—can I see more?
Absolutely! If those particle effects caught your eye, head to the Effect Gallery on our homepage. You can play around with them there anytime.

How can I give feedback or report issues?
Feel free to leave a comment at the bottom of the page! Share your scores, report bugs, or just say hello—we welcome it all.
