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 Acer H6546Ki ist ein heller Full-HD-Lampenbeamer für Wohnzimmer, die sich nicht ganz abdunkeln lassen. 5.200 ANSI-Lumen reichen für Sport bei Restlicht und für Präsentationen bei Deckenlicht. Der Haken: Der Lüfter ist im Normalmodus gut hörbar, Lens Shift fehlt, und Netflix läuft nur über einen zusätzlichen Stick. Für tiefes Schwarz im Heimkino passt er weniger.

Pros

  • 5.200 ANSI-Lumen, Bild bleibt bei Restlicht im Wohnzimmer gut erkennbar
  • Satte Farben und scharfes Bild mit nativ 1920 x 1080 Pixeln
  • Eco-Modus mit 4.160 Lumen, Lampe hält dann bis zu 10.000 h
  • Funkadapter für Bildschirmspiegelung von Handy und Laptop liegt bei
  • Full-HD-3D per Frame Packing über HDMI
  • USB-A-Anschluss versorgt einen Streaming-Stick ohne eigenes Netzteil

Cons

  • Lüfter im Normalmodus in leisen Filmszenen gut hörbar
  • Kein Lens Shift, Zoom nur Faktor 1,1
  • Kein Betriebssystem, Netflix nur über externen Streaming-Stick
  • 3-W-Mono-Lautsprecher reicht kaum für Dialoge
  • Lampe nach 5.000 h im Normalmodus fällig, kein 4K und HDR

Der TCL C1 ist ein mobiler Full-HD-Beamer für dunkle Räume: Er stellt das Bild selbst scharf und gerade, bringt Google TV mit offizieller Netflix-App und läuft rund 2 h per Akku. Der Haken sind nur 230 ISO-Lumen – bei Tageslicht wird das Bild blass, HDR bleibt wirkungslos. Für Filmabende im Schlafzimmer taugt er, als Fernseher-Ersatz im Wohnzimmer nicht.

Pros

  • Natives Full HD mit ruhigem, scharfem Bild ohne Regenbogeneffekt
  • Google TV mit offizieller Netflix-App, kein Streaming-Stick nötig
  • Autofokus und Trapezkorrektur richten das Bild in rund 15 Sekunden aus
  • Schwenkfuß mit 285 Grad und Stativgewinde, projiziert auch an die Decke
  • Akku für rund 2 h, genug für einen Spielfilm ohne Kabel
  • 8-W-Lautsprecher spielt auch laut klar und ohne Verzerrung

Cons

  • Nur 230 ISO-Lumen, bei Tageslicht kaum erkennbares Bild
  • Kontrast 1500:1, Schwarz wirkt in dunklen Szenen grau
  • Träge Bedienung: rund eine Minute bis zum Bild, verzögerte Menüs
  • Lüfter hörbar, in ruhigen Szenen teils störend
  • Ohne optischen Zoom, digitale Trapezkorrektur macht das Bild unschärfer
