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 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
Der XGIMI MoGo 4 ist ein mobiler Full-HD-Beamer mit eingebautem Akku, der im abgedunkelten Raum ein scharfes, farbkräftiges Bild zeigt und sich fast von selbst einrichtet. Netflix läuft offiziell unter Google TV, im Eco-Modus reicht der Akku für einen langen Film. Der Haken: nur bei Dunkelheit wirklich brauchbar, dazu graues Schwarz und ein zeitweise träges Menü.
Pros
- Scharfes Full-HD-Bild von der Mitte bis zum Rand
- Akku hält im Eco-Modus knapp 200 min bis gut 3 h
- Netflix als offizielle App unter Google TV, kein Stick nötig
- Bild steht nach rund 15 s dank Autofokus und Trapezkorrektur
- Input Lag von gut 22 ms im Spielmodus
- Klare Sprachwiedergabe ohne Verzerrung bei voller Lautstärke
Cons
- Braucht abgedunkelten Raum, bei Tageslicht saufen dunkle Szenen ab
- Kontrast von rund 320:1, Schwarz wirkt dunkelgrau
- Menü reagiert zeitweise verzögert, etwa beim App-Wechsel
- Im Akkubetrieb nur 150 bis 250 Lumen im Eco-Modus
- HDR10 nur in Apps, nicht über HDMI
