Guides
What the tools on this site are actually for, written by people who have cleaned a lot of monitors and lit a lot of video calls with them. Each guide explains the mechanism, gives the honest limits, and links the screen or tool that does the work.
How to clean a monitor screen
Microfiber, distilled water, and nothing else. How to clean a monitor or TV screen without stripping the coating, and how to check your work with a white screen.
How to test for dead pixels, and what can actually be fixed
Cycle white, black, red, green and blue to find dead and stuck pixels, tell the two apart, and hear the honest odds on fixing each before you try.
Use your screen as a key light for video calls
A display filled with warm white is a genuinely good soft light. Where to put it, how bright to run it, and why a big dim panel beats a small bright bulb on camera.
Bias lighting: why the light belongs behind the screen
A soft light behind the display eases eye strain and deepens blacks. The mechanism, the right color, and how to try it tonight with a screen you own.
OLED burn-in, without the panic
Burn-in is uneven wear, not damage from a single image. What actually causes it on OLED, how retention differs, and the habits that make it a non-issue.
Green screen setup without a studio
Why keying uses green, why fabric beats a monitor for people, and the lighting that makes a cheap backdrop key cleanly. Honest advice from a color site.
Check a new monitor before the return window closes
Fifteen minutes of color fields and one gradient find dead pixels, backlight bleed, banding and uniformity problems while a return is still free.
Blue light and sleep: what screens actually do
The melanopsin mechanism is real; the panic is oversold. What evening screens do to melatonin, why dim beats warm, and where red light earns its place.
