What is used to test a monitor's spatial resolution?

• A. SMPTE test pattern
• B. Moire pattern
• C. Spinning top test
• D. Star pattern-type resolution test

Answer: (A)

Testing a monitor’s spatial resolution focuses on how well it can render fine details. A pattern that shows progressively tighter lines lets you see the point at which those lines blur together, giving a practical measure of how finely the display can resolve detail. The SMPTE test pattern is built for this purpose: it presents multiple groups of high-contrast vertical and horizontal bars at known spacings, so you can identify the smallest pattern that remains distinct on that monitor. This makes it a reliable, standard reference for evaluating resolution and also helps with checking alignment and geometry. Other patterns aren’t as direct for measuring true resolution. A moire pattern arises from interference between grids and sampling and isn’t a clean measure of how many line pairs the screen can resolve. A spinning top pattern mainly checks geometry, focus, or distortion rather than resolution. A star-pattern type resolution test exists in some kits but is less standardized and not as straightforward to interpret for exact resolution limits as the SMPTE pattern.
