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 Dangbei DBOX02 Pro ist ein heller 4K-Laser-Beamer mit Schwenk-Ständer für abdunkelbare Wohnräume und das Heimkino mit Leinwand. Er zeigt ein scharfes, ruhiges Bild ohne Speckle, und Netflix läuft offiziell unter Google TV. Der Haken: mäßiger Kontrast mit grauem Schwarz. Fällt Sonne auf die Wand, fehlt Licht, und für Actionfilme brauchst du eine Soundbar.
Pros
- Scharfes Bild bis in die Ecken, Ausleuchtung bei 98 %
- Kaum Regenbogeneffekt und kein Laser-Speckle
- Netflix offiziell unter Google TV, flüssige Oberfläche
- 1.800 ANSI-Lumen im Alltag bei leisem Lüfter
- Gimbal-Ständer neigt bis zur Decke und hält die Position
- HDMI 2.1 mit eARC, optischer Ausgang und LAN
Cons
- Nativer Kontrast nur 880:1, Nachtszenen mit Grauschleier
- Autofokus braucht nach dem Einschalten oft einen zweiten Anlauf
- Lautsprecher für Actionfilme zu schwach
- Kein optischer Zoom und kein Lens Shift
- Im Modus Hohe Leistung laute 43 dB
Der Nebula Cosmos 4K SE ist ein bequemer 4K-Allrounder fürs abgedunkelte Wohnzimmer: Google TV mit offiziellem Netflix, kräftige 30-W-Lautsprecher und Autofokus stecken in einem tragbaren Gehäuse. In den Filmmodi kommen rund 1.300 statt 1.800 ANSI-Lumen an. Der Haken ist graues Schwarz bei nativ 400:1, dunkle Thriller verlieren Details. Bei Tageslicht oder für Kinopuristen taugt er nicht.
Pros
- Netflix, Disney+ und Mediatheken laufen offiziell über Google TV
- Helles, farbkräftiges Bild mit rund 1.300 ANSI-Lumen in den Filmmodi
- Kräftiger 30-W-Ton füllt ein 30-m²-Wohnzimmer ohne Verzerrung
- eARC gibt Dolby Atmos an Soundbar oder AV-Receiver weiter
- Autofokus und Trapezkorrektur richten das Bild zwischen 1,5 und 4 m selbst aus
- Mit 4,5 kg und Griff schnell in einen anderen Raum getragen
Cons
- Nativ 400:1 Kontrast: dunkle Szenen werden grau und verlieren Details
- Nur rund 1.300 statt versprochener 1.800 ANSI-Lumen in Filmmodi
- Lüfter mit rund 45 dB statt angegebener 28 dB in leisen Szenen hörbar
- Kein optischer Zoom und kein Lens Shift
- Dolby Vision macht dunkle Szenen dunkler, HDR nicht abschaltbar
