Conas a ríomhtar é seo?
Leithead 4800mm÷Páirc 2.5mm=1920px
1Determine pitch: Based on viewing distance 6.0m, auto-recommended pitch P2.5 (1 arcmin model: PPD≈45 → P = D ÷ 2.58)
2Calculate resolution: Leithead an scáileáin 4.80m ÷ pitch 2.5mm = 1920 px/row, height yields 1080 sraitheanna
3Assess quality: 1920 × 1080 = 2.07M pixels, meeting HD Iomlán caighdeán

Golden rule: Distance first → P = D ÷ 2.58 (PPD≈45 sweet spot). D ÷ 3.44 = retina (PPD 60).
📋 Latest Update Log
V1.1 — Replaced empirical formulas (P×2.5 / H×30) with 1 arcmin visual acuity model: PPD (Pixels Per Degree), SMPTE RP166, THX 5° FOV criterion. Added retina distance (PPD 60), expanded pitch library (P0.9–P15.6) with industry-standard classic values.
