Mars 3
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 BenQ TK705i ist ein kompakter 4K-LED-Beamer für Tisch oder Decke, der ab Werk natürliche Farben zeigt und mit rund 12 ms Input Lag schnell auf Konsolen reagiert. Google TV mit Netflix ist eingebaut, Motorzoom und Automatik erleichtern die Aufstellung. Die Haken: Schwarz wirkt dunkelgrau, und der Ton verlangt eine Soundbar. Fürs Wohnzimmer mit Restlicht passt er gut, fürs dunkle Heimkino weniger.
Pros
- Natürliche Farben ab Werk, BT.709 nahezu vollständig abgedeckt
- Input Lag rund 12 ms, mit Gaming Boost 9,3 ms
- Google TV mit offizieller Netflix-App, Chromecast und AirPlay
- Optischer Motorzoom 1,0 bis 1,3:1, 100 Zoll aus 2,21 bis 2,88 m
- Autofokus und Trapezkorrektur richten das Bild nach dem Verrücken neu aus
- Kompakt mit 3,8 kg, LED-Lichtquelle ohne Lampenwechsel
Cons
- Nativer Kontrast um 788:1, Schwarz wirkt in dunklen Szenen grau
- Lautsprecher 2 x 8 W klingen dünn und schrill bei höherer Lautstärke
- 4K nur mit 60 Hz trotz HDMI 2.1, kein VRR
- Farbtreu nur rund 1.400 Lumen statt 3.000, an Sonnentagen zu schwach
- Kein Lens Shift und kein LAN-Anschluss
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
