Lagom-style sharpness patterns
Each block is a 1px alternating black/white grid drawn at the device pixel ratio. On a correctly-scaled monitor with neutral sharpness, every block should look like a uniform mid-grey at arm's length. Visible banding, moire, or shimmer means OS scaling, monitor over-sharpening, or a non-native resolution is interfering with pixel-perfect rendering.
Text clarity at 8 sizes × 3 fonts
Read each block. Small text should remain crisp, not fuzzy. The same paragraph is rendered in serif, sans, and monospace at 12-64 px so you can compare hinting, stem thickness, and grayscale anti-aliasing.
Color fringing detection
Look at the edges of each character. If you see thin red, green, or blue halos along letter strokes, that is chromatic aberration from sub-pixel anti-aliasing on a non-RGB-stripe panel (e.g. RWBG, BGR, OLED PenTile). Black-on-white and white-on-black often render with different sub-pixel hinting.

Sub-pixel layout ruler
A 1px wide repeating pattern of pure red, green, blue, and black columns. Lean in close (or use a phone camera macro). On a standard RGB-stripe LCD you should see a clean R-G-B-K stripe; on a BGR panel the order reverses; OLEDs with PenTile arrangement will look mottled. This tells you the pixel layout your monitor uses for sub-pixel anti-aliasing.
