Overview
This guide uses Selection Logic so you can choose by need and evidence. Key traps: 8K hype; panel type confusion; claimed vs peak brightness.
Theory anchor: T1 Matching Theorem—good choices match your needs, not "objectively best" configs.
Step 1 → Need clarification (M1)
Use M1 Need Clarification to define real usage and constraints.
Scenario analysis
| Scenario | Primary considerations |
|---|---|
| Movies & series | contrast, black level, HDR, size |
| Gaming | latency, VRR, refresh rate |
| Sports & news | motion clarity, brightness |
| Living room & distance | size, brightness, viewing angle |
Example need list
- Must-have: key metrics for main scenario
- Nice-to-have: experience and convenience
- Bonus: support, brand, expansion
Step 2 → Allocate cognitive budget (T2)
These products are typically medium-to-high value and low reversibility. Use T2 Cognitive Budget and Decision Reversibility to allocate time.
Suggested time: need clarification 30 min; evidence gathering 2–2 h; comparison 1 h.
Step 3 → Multi-dimensional evaluation (M2)
Use M2 Multi-Dimensional Evaluation. In this guide, stress: Stress: 8K hype—limited benefit with current content and viewing distance; panel type—OLED/QLED/LCD trade-offs by scenario; claimed vs peak brightness—rely on sustained brightness measurements.
Evaluation dimensions
| Dimension | Sub-items | Evidence sources |
|---|---|---|
| Image quality | contrast, gamut, HDR, brightness | reviews, measurements |
| Panel & tech | OLED/QLED/LCD, local dimming | specs, reviews |
| Gaming & ports | latency, VRR, HDMI 2.1 | measurements |
| Size & distance | inches, viewing distance | recommendations, need match |
Weight example
Per T1, set weights by your needs, e.g. Image quality 40%%; panel & gaming 35%%; size & distance 15%%; price 10%%.
Step 4 → Bias & persuasion hazards
- Anchoring effect: don't anchor on high-end prices; fix budget and needs first.
- Confirmation bias: write criteria before browsing; avoid justifying a favorite.
- Halo effect: brand and marketing carry value assumptions—see T1.2.
- Specs and claims: rely on measurements and third-party data; beware claimed vs actual.
Step 5 → Decision + validation (M5)
Apply M5 Decision Validation.
Checklist: core needs met (fit score); within budget; satisficing threshold (T4.2); still satisfied after cooling-off.
Post-purchase: Need consistency—after 1–3 weeks, check real usage vs expectations, key metrics, regret points.
