Frequently asked questions
- What's a normal amount of glow?
- Some IPS glow or OLED near-black glow is normal and shifts with viewing angle; backlight bleed stays fixed in the same spot regardless of angle.
- What room conditions should I use?
- A fully dark room gives the most accurate result - ambient light hides real defects.
