Form factorBasic form of the projector, in this order: if it sits right in front of the wall as an ultra-short-throw unit, it is a laser TV. If it has a built-in battery, it is mini & portable – even with a stand. A swivel stand or gimbal without a battery means compact with swivel stand. Everything else is classic, for table or ceiling.

Verdict

Pros & cons

Der JMGO N1S 4K ist ein kompakter Triple-Laser-Beamer mit Schwenk-Ständer und Google TV samt offizieller Netflix-App. Für Filmabende im abgedunkelten Raum liefert er ein scharfes, sehr farbkräftiges Bild und bleibt mit 26 dB im Betrieb kaum hörbar. Der Haken: Schwarz wirkt dunkelgrau, das Menü reagiert zäh, und es gibt nur einen HDMI-Eingang. Bei Tageslicht reicht seine Helligkeit nicht.

Pros

  • Scharfes, sehr farbkräftiges Laserbild bei 4K per Pixel-Shift
  • Mit 26 dB auch in leisen Filmszenen kaum hörbar
  • Google TV mit offizieller Netflix-App, kein Streaming-Stick nötig
  • Gimbal mit 127 Grad Neigung, Autofokus und automatische Trapezkorrektur
  • Input Lag von 17 ms für Konsolenspiele
  • HDMI 2.1 mit eARC für Soundbar oder AV-Receiver

Cons

  • Schwarz wirkt im dunklen Raum dunkelgrau, feine Schatten laufen zusammen
  • Nur ein HDMI-Eingang, keine Klinkenbuchse
  • Menü hängt teils sekundenlang, Bildeinstellung während des Films zäh
  • Grauer Lichtsaum um das Bild nach der Trapezkorrektur
  • Fernbedienung unbeleuchtet, Tasten im Dunkeln schwer zu ertasten

Der Nebula Mars 3 Air ist ein mobiler Full-HD-Beamer mit Akku und Google TV, der im dunklen Raum überzeugt. Netflix läuft offiziell ohne Streaming-Stick, Fokus und Trapez stellt er selbst ein. Der Haken: 400 ANSI-Lumen reichen nicht bei Restlicht, und am Akku bleiben nur 145 Lumen.

Pros

  • Natives Full HD, scharf bis etwa 90 Zoll im dunklen Raum
  • Gemessene 399 ANSI-Lumen, fast exakt die Herstellerangabe
  • Netflix offiziell unter Google TV, ohne Streaming-Stick
  • Modus Standard zeigt ausgewogene Farben bei nur 4 % weniger Licht
  • Autofokus und Trapezkorrektur richten das Bild in Sekunden aus
  • 2 x 8 W Lautsprecher mit verständlichen Dialogen und sauberem Bass

Cons

  • Am Akku nur rund 145 ANSI-Lumen im automatischen Eco-Modus
  • Bei Restlicht oder Sonne wird das Bild schnell blass
  • Rund 45 ms Input-Lag, zu träge für schnelle Konsolenspiele
  • HDR-Spitzlichter wirken matt, nativer Kontrast nur 400:1
  • Laden nur per Netzteil, keine Objektivklappe und kein IP-Schutz
