🔍 Key Concepts

• Typical pixel density (pixels per inch, PPI) of modern LCD panels used in devices like smartphones, tablets, and modern navigation displays • The trend in display technology over time (older CRTs vs. early LCDs vs. modern high‑resolution screens) • Difference between practical common values and theoretical or extreme lab values for PPI

💭 Think About

• Think about the pixel density of common devices you use daily (phones, laptops, tablets). Would these usually be below 50 PPI, around 100–150 PPI, or much higher? • Consider how text and chart details appear on modern electronic chart displays—would that level of clarity be possible at only 50 or 125 pixels per inch? • Ask yourself whether a limit like "no more than 125 PPI" makes sense in light of advertising for "Retina" or high‑resolution displays you may have seen.

✅ Before You Answer

• Compare each option to real‑world examples you’re familiar with (e.g., smartphone, tablet, laptop screen specifications). • Eliminate any choice that conflicts with what you know about high‑resolution commercial displays currently on the market. • Be careful with extremes: check whether "no more than" or very high numbers like 1,000 PPI sound realistic for commonly available, modern LCDs used in navigation and consumer electronics.
