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 IRIS Ultra Max ist ein heller Kurzdistanz-Laser für Bilder ab 120 Zoll und schnelles 4K-Gaming mit 120 Hz bei nur 5,5 ms Verzögerung. Im Filmmodus bleiben gut 4.300 Lumen, mit Blende F5.0 gibt es tiefes Schwarz bei 2.500 Lumen. Optischer Zoom, Lens Shift und Motor-Ständer erleichtern die Aufstellung. Der Haken: verschachtelte Menüs und wackliges Dolby Vision mit externen Playern kosten dich Zeit beim Einrichten.
Pros
- 4K mit 120 Hz an zwei HDMI-2.1-Eingängen, Latenz um 5,5 ms
- Gut 4.300 Lumen im farbtreuen Filmmodus, genug für Restlicht
- Dual-Iris hebt den Kontrast bei F5.0 auf 5.100:1 bis 8.600:1
- Optischer Zoom 0,88 bis 1,7:1 und Lens Shift ohne Schärfeverlust
- Motor-Ständer dreht 360 Grad, speichert bis zu zehn Positionen
- Google TV mit offizieller Netflix-App und kräftigem 25-W-Ton
Cons
- Dolby Vision von direkt angeschlossenen Blu-ray-Playern kommt nicht immer an
- Bildmenüs unübersichtlich, einfache Profile für Raumlicht fehlen
- Automatische Ausrichtung trifft an wechselnden Flächen nicht immer
- Lüfter rauscht mit rund 30 dB statt versprochener 26 dB
- Regenbogeneffekte bei schnellen Bewegungen für Empfindliche sichtbar
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
