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 Mars 3 ist ein heller Akku-Beamer für draußen: 1000 ANSI-Lumen in nativem Full HD reichen im Garten schon ab der Dämmerung, der Akku hält bei voller Helligkeit rund 2 h. Er passt zu dir, wenn du Filmabende ohne Steckdose willst. Der Haken: nur 400:1 Kontrast, gut 4,5 kg Gewicht und Netflix nur über Umwege.
Pros
- 1000 ANSI-Lumen im Akkubetrieb, draußen schon ab der Dämmerung nutzbar
- Natives Full HD, scharf bis etwa 120 Zoll
- 185-Wh-Akku: rund 2 h bei voller Helligkeit, 4 bis 5 h im Eco-Modus
- Robust für draußen: IPX3, sturzfest aus 0,5 m, Anschlüsse hinter Gummilippe
- 40 W Lautsprecher mit kräftigem Bass, auch als Bluetooth-Box nutzbar
- Android TV mit Chromecast, lädt Handys per USB-C mit 15 W
Cons
- Nativer Kontrast nur 400:1, Schwarz wirkt bei Restlicht grau
- Netflix nur über Nebula Play, hakelig mit der Fernbedienung
- Mit gut 4,5 kg und klobigem Netzteil nichts für den Rucksack
- Autofokus und Trapezkorrektur sitzen oft nicht genau, Nachjustieren nötig
- Menü reagiert mit 2 GB Arbeitsspeicher träge
Der XGIMI Horizon 20 Pro ist ein heller 4K-Laserbeamer fürs Wohnzimmer, der auch bei Restlicht trägt und dank Zoom und Lens Shift nicht mittig stehen muss. Statt 4.100 liefert er ab Werk rund 2.800 Lumen, für Tageslicht reicht das. Der Haken ist der erhöhte Schwarzwert: Dunkle Filmszenen bekommen einen bläulichen Schleier. Für ein dunkles Heimkino ist er nicht die erste Wahl.
Pros
- Rund 2.800 ANSI-Lumen ab Werk, mit Luminanz-Boost gut 3.500 Lumen
- Optischer Zoom 1,2 bis 1,5:1 und Lens Shift bis 120 % vertikal
- Google TV mit offizieller Netflix-App, dazu Chromecast
- Mit Super Frame bei 120 Hz praktisch kein Input Lag
- Farbstark mit 85 bis 92 % DCI-P3
- Laserquelle mit 20.000 Stunden, ohne Lampenwechsel
Cons
- Erhöhter Schwarzwert, Kontrast nur rund 1.250 bis 1.400:1
- Beworbene 4.100 Lumen erreicht nur der grünstichige High-Power-Modus
- Geringer Input Lag nur in Full HD, 4K höchstens 60 Hz
- Projektor-Menüs schlecht erklärt, Zoom und Lens Shift erst nach Einrichtung
- Regenbogeneffekt und Laser-Speckle auf Kontrastleinwänden sichtbar
