BlackScreen.live
The Lab Behind the Tools
BlackScreen.live is built by two display hardware engineers who got tired of testing monitors with compressed YouTube videos. Here's who we are, how we work, and why we built everything for free.
How This Started
In 2023, Marcus bought a high-end IPS gaming monitor and suspected it had backlight bleed. He tried the usual approach: play a dark YouTube video in fullscreen and judge from there. The problem was immediately obvious — H.264 compression was crushing the blacks, making it impossible to tell the difference between the monitor's actual performance and the video codec's limitations.
— Marcus Chen, co-founder
Daniel joined shortly after, bringing his background in OLED panel research. What started as a single black screen page became a full diagnostic suite: a guided display test, a stuck pixel fixer using chromatic agitation, a screen cleaning mode, a PPI calculator, and a growing library of technical articles grounded in display physics.
Everything on this site is rendered natively by your GPU — no video compression, no streaming artifacts. When you select a color, that hex value goes directly to your pixels. That is the entire point.
Who We Are
Marcus has spent seven years reviewing monitors for hardware enthusiast forums and independent review communities. He has personally tested over 200 panels across IPS, VA, TN, and OLED technologies, developing standardized testing protocols used by the community.
He leads tool development and the display test methodology at BlackScreen.live, and writes the majority of the Wiki articles on panel defects and diagnostic techniques.
Daniel's background is in display material science, with a focus on OLED degradation mechanisms and long-term panel longevity. Before co-founding BlackScreen.live, he contributed to OLED burn-in research in the consumer electronics space.
He leads the scientific content on this site — including the OLED longevity guides, the pixel physics articles, and the panel coating chemistry research — ensuring everything is grounded in verifiable display science.
Our Testing Methodology
Every article and tool recommendation on this site comes from a consistent, controlled testing approach. We document our setup so you can reproduce our results or adapt them for your own evaluation.
| Test Condition | Our Standard |
|---|---|
| Warm-up period | 30 minutes from cold start before any measurement. Panels exhibit different thermal behavior when first powered on. |
| Room lighting | Fully dark room for backlight bleed and IPS glow tests. Controlled ambient (200 lux) for color and uniformity evaluation. |
| Test signal source | Native browser rendering at the display's native resolution. No video decoding, no scaling, no post-processing pipeline. |
| Camera for documentation | Fixed exposure, ISO 1600, f/4, 1/30s — consistent across all panel documentation to allow side-by-side comparison. |
| Defect classification | ISO 9241-307 Class II standard as the baseline for dead pixel tolerance. We note where panels exceed or fall below this specification. |
| OLED longevity testing | Panels run under controlled workloads (8 hours/day, static taskbar, 150 nits) with periodic uniformity measurements over 6-month periods. |
Why Trust This Site
-
First-hand testing, not aggregated opinions We do not republish specs from manufacturer datasheets. Every claim about panel behavior on this site comes from units we have tested under the conditions described in our methodology.
-
Grounded in published standards We reference ISO 9241-307 for pixel defect classification, VESA DisplayHDR for HDR performance tiers, and peer-reviewed display science literature for OLED degradation data. Sources are cited in each article.
-
Tools built for accuracy, not engagement Our diagnostic tools produce native GPU-rendered output. There is no video compression, no streaming pipeline, and no image processing between the hex value we set and the pixels on your screen.
-
We tell you when something won't work Our Dead Pixel Fixer documentation explicitly states it cannot repair truly dead pixels — only stuck ones. We would rather give you accurate expectations than overclaim tool capabilities.
-
Free, with no data collection No account required. No usage tracking beyond standard anonymized analytics. The tools run entirely client-side in your browser. We are monetized through display advertising, which is disclosed in our privacy policy.
Questions or Corrections?
If you spot an error in our methodology, have a monitor you'd like us to include in our database, or just want to share your test results — we read everything.
