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 Epson EH-LS670B ist ein Laser-TV, der mit rund 3.300 bis 3.800 lm auch bei Tageslicht ein großes Bild bis 120 Zoll an die Wand bringt. Google TV mit Netflix und 3LCD ohne Regenbogeneffekt machen ihn zum vollwertigen Fernseher-Ersatz. Der Haken: kleiner Farbraum, graues Schwarz und kein Dolby Vision – im abgedunkelten Heimkino fällt das auf.

Pros

  • Sehr hell: 3.323 lm im Modus Natural, bis 3.776 lm in Dynamic
  • Google TV mit offizieller Netflix-App, kein Streaming-Stick nötig
  • 3LCD-Technik ohne Regenbogeneffekt
  • Leise: kaum hörbar über 33 dB Raumgeräusch
  • Gleichmäßige Ausleuchtung mit 89 % am dunkelsten Punkt auf 100 Zoll
  • Drei HDMI-Eingänge, eARC mit Dolby-Atmos-Durchleitung

Cons

  • Kleiner Farbraum mit rund 76 % DCI-P3, Blau übersättigt
  • Kein Dolby Vision, kein HDR10+, helle Spitzlichter laufen weiß aus
  • Schwarz wirkt in dunklen Szenen als dunkles Grau
  • Zwischenbildberechnung erzeugt Artefakte bei Personen und Zeichentrick
  • Schlichte Fernbedienung ohne Beleuchtung und ohne Stummtaste

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
