What CRT Colors ACTUALLY Look Like Up Close (4K Macro)
How do CRT colors work up close? In this video, we zoom into a real CRT monitor screen to see how an electron beam and phosphor dots create the colors you see. If you love retro gaming tech and want to understand the science of spatial mixing and additive color on a real tube TV, this close-up look reveals the secret of how red, green, and blue stripes trick your brain.
We also look at how adjusting brightness and contrast changes the electron gun bias voltage and video signal amplitude to create pure white, gray, and bright neon colors.
