Bm-hd1080p
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 HAPPRUN Bm-hd1080p ist ein einfacher Full-HD-Beamer für dunkle Räume, den Autofokus und automatische Trapezkorrektur schnell aufstellen. Statt Tageslicht und 4K liefert er gemessen rund 250 ANSI-Lumen, nativ 1920 x 1080 Pixel und ein graues Schwarz. Für Filmabende im Schlafzimmer oder Garten nach Sonnenuntergang taugt er; dich stören aber der mit 45 dB hörbare Lüfter und schwache 8-W-Lautsprecher.
Pros
- Autofokus und automatische Trapezkorrektur stellen das Bild nach dem Einschalten selbst ein
- Bei Dunkelheit bis etwa 198 cm Bildbreite, rund 90 Zoll
- Natives Full HD, Untertitel in der Bildmitte gut lesbar
- Heller als viele Mini-Beamer der Billigklasse
- Bluetooth für Soundbar oder Kopfhörer, dazu Wi-Fi 6
Cons
- Gemessen rund 250 statt beworbener 1.500 ANSI-Lumen, bei Tageslicht unbrauchbar
- Kontrast im Schachbrett knapp 9:1, Schwarz wirkt grau
- Lüfter mit 45 dB in ruhigen Szenen ständig hörbar
- Nur ein HDMI-Eingang, kein optischer Zoom und kein Lens Shift
- Netflix und viele Mediatheken fehlen je nach Ausführung
