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 Dangbei N2 mini ist ein Mini-Beamer mit Schwenk-Ständer für dunkle Schlafzimmer und die Zimmerdecke. Er zeigt echtes Full HD mit lizenziertem Netflix, braucht mit 200 ISO-Lumen aber geschlossene Rollläden und volle Helligkeit. Schwacher Schwarzwert, unscharfe Bildränder, ein dünnes App-Angebot ohne Disney+ und kein Akku grenzen ihn deutlich ein.
Pros
- Natives Full HD, bis 100 Zoll im Dunkeln scharf
- Ständer neigt um 190 Grad, projiziert bis an die Zimmerdecke
- Netflix, Prime Video und YouTube laufen lizenziert
- Autofokus und Trapezkorrektur stellen das Bild in Sekunden ein
- Leiser Lüfter mit höchstens 39 dB im Betrieb
Cons
- Mit 200 ISO-Lumen nur in abgedunkelten Räumen brauchbar
- Nativer Kontrast 2000:1 verschluckt Details in dunklen Szenen
- Dünnes App-Angebot, Disney+, Max und Apple TV+ fehlen
- Bildränder etwas dunkler und leicht unscharf
- Kein Akku, Betrieb nur an der Steckdose
