Review & Evaluation Policy
How we compare portable monitors and establish practical workspace recommendations.
Comparison Criteria
Our product evaluations focus on the practical failure points of mobile dual-screen working environments:
- Cable Logistics & Power Handshake
- Distinguishing monitors that run on single-cable USB-C DisplayPort Alt Mode from those requiring a dedicated auxiliary wall adapter.
- Panel Usability & Finish
- Evaluating anti-glare matte treatments versus glossy screens for variable coffee shop and transit lighting.
- Stand Mechanics & Packed Mass
- Weighing integrated kickstands against magnetic folding cases that slip on narrow cafe tables, plus total carry weight.
- Host Battery Impact
- Analyzing how high refresh rates (120Hz+) or 4K panel draws drain the connected laptop battery during transit.
Evidence Scope & Limitations
AltMode Index operates under a specification-research evidence model. We do not conduct destructive teardowns, custom luminance meter calibrations, or colorimeter lab tests. Evaluations reflect comparative analysis of verified seller manifests, engineering documentation, and reported user trade-offs.
Package Content Auditing Standard
We explicitly audit retail listings for missing essentials, such as absent USB-C 3.1 Gen 2 cables, omitted mini-HDMI adapters, or the lack of an external power brick, warning readers before purchase.
