Hands-on writing about displays — how to inspect them, what the results mean, and when a flaw is genuinely worth acting on. Every guide is written from real testing on real panels, not rewritten spec sheets.
Tell a real defect apart from dust and IPS glow, run the colour sequence in the right order, and find out what your warranty actually covers before you start a return.
Most guides here pair with the free fullscreen screens on this site. You can jump straight into a pure white screen online for dust and dead-pixel checks, a black screen for backlight bleed and hot pixels, or a grey screen for uniformity and banding. Nothing to install, no account, no ads.
