What to Look For During This Test
Contrast Gradient Steps
Verify smooth transitions across all 32 grayscale bars without visible quantization steps, posterization, or banding.
Subpixel Sharpness & ClearType
Ensure fine 1-pixel alternating line patterns render crisply without moiré fringe or halo artifacts around typography.
SMPTE Standard Color Bars
Check color alignment and clipping across 100% and 75% saturated primary and secondary color fields.

Testing Questions & Answers
Adjust your monitor contrast slider until the brightest step (97-100% white) is distinguishable without clipping into a solid white block.
