Score formula
(Brightness & Usable Lumens x 0.25) + (Image Fidelity x 0.25) + (Portability & Setup x 0.20) + (Streaming Ecosystem x 0.15) + (Value per Dollar x 0.15)What each component measures
| Component | Weight | What it measures |
|---|---|---|
| Brightness & Usable Lumens | 25% | Rated output in the maker's own unit (ISO for XGIMI, ANSI for Anker and BenQ) judged against real-room usability — 300 ANSI to 5700 ISO across this field |
| Image Fidelity | 25% | Resolution (1080p vs true 4K), color gamut (up to 110% BT.2020), and contrast — how sharp and accurate the picture is for both text and film |
| Portability & Setup | 20% | Weight and form factor, internal battery, and auto focus/keystone/lens-shift — how fast you go from carry case to a square image |
| Streaming Ecosystem | 15% | Built-in Google TV vs a bundled dongle, officially licensed Netflix, and casting support — how self-contained the unit is |
| Value per Dollar | 15% | Delivered capability against current Amazon price — rewards units that cover the essentials without a premium for size or brand |
How to read the number
A 9.1 on the XGIMI Horizon 20 Max reflects the brightest, sharpest image in the field with reference-grade Dolby Vision, but its value factor pulls the composite below a hypothetical perfect score because $2,249 buys more projector than a home office needs. The 8.7 on the MoGo 4 Laser is the composite in action — it trails on brightness and resolution but wins on portability, color, streaming, and price, which is why it's the all-around pick. Brightness and image fidelity are weighted at 0.25 each because they're the two specs buyers most often misread. Scores synthesize manufacturer specifications from XGIMI, Anker, and BenQ with editorial coverage from RTINGS, Trusted Reviews, TechRadar, and Techaeris.

How DeskGearHQ scores anything
DeskGear Portable Projector Score is a category-specific composite. It sits on top of the site-wide framework: DeskGearHQ does not run a testing lab, and every score is an editorial synthesis of named expert sources, manufacturer documentation, and practitioner-community signal — explicitly not a laboratory measurement. The base DeskGear Score, its factor definitions, the full source stack, and the refresh policy are documented on the methodology page.
