Buying Guide
Check the Display Resolution
A projector described as “4K supported” may only accept a 4K signal before displaying it at 1080p or lower. Look for a 3840 × 2160 displayed resolution when 4K detail matters.
Use Standardized Brightness Figures
ANSI and ISO lumens are standardized measurements, although their values are not directly interchangeable. Avoid comparing them with vague figures such as “LED lumens” or unqualified brightness claims.
Plan the Placement
Optical zoom and lens shift preserve more image quality than strong digital zoom or keystone correction. Check the throw ratio and required distance before choosing a screen size.
Verify Streaming Access
Google TV or Android TV does not automatically guarantee licensed Netflix support. Look for explicit Netflix certification or plan to connect a separate streaming stick.
