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 Hisense C3 ist ein kompakter Triple-Laser-Beamer mit Schwenksockel, der im abgedunkelten Raum ein farbstarkes, scharfes 4K-Bild zeigt. Optischer Zoom, Autofokus und offizielles Netflix machen ihn flexibel an wechselnden Orten, mit 2.050 bis 2.150 Lumen reicht er für Bildbreiten bis 4,20 m. Der Haken: Schwarz bleibt grau, und für helle Wohnzimmer ist er zu lichtschwach.
Pros
- Triple-Laser deckt Rec.709 voll und Rec.2020 zu rund 99 % ab
- Ehrliche Helligkeit: kalibriert 2.050 bis 2.150 von 2.500 Lumen
- Optischer Zoom 1,0 bis 1,3:1 per Fernbedienung ohne Schärfeverlust
- 4K mit 60 Hz bei 20 bis 25 ms Input Lag
- Schwenksockel und Autofokus richten das Bild in Minuten ein
- Netflix offiziell unter VIDAA, dazu Dolby Vision und HDR10+
Cons
- Schwarzwert schwach: Schachbrett-Kontrast nur 372:1, Balken bleiben dunkelgrau
- Lüfter bei warmem Raum laut: bis 39 dB bei 35 °C
- Kein Lens Shift, Trapezkorrektur kostet Schärfe
- 4K nur mit 60 Hz, 120 Hz erst in Full HD
- Werbung auf der VIDAA-Startseite lässt sich nicht ganz abschalten
Der Nebula Cosmos 4K SE ist ein bequemer 4K-Allrounder fürs abgedunkelte Wohnzimmer: Google TV mit offiziellem Netflix, kräftige 30-W-Lautsprecher und Autofokus stecken in einem tragbaren Gehäuse. In den Filmmodi kommen rund 1.300 statt 1.800 ANSI-Lumen an. Der Haken ist graues Schwarz bei nativ 400:1, dunkle Thriller verlieren Details. Bei Tageslicht oder für Kinopuristen taugt er nicht.
Pros
- Netflix, Disney+ und Mediatheken laufen offiziell über Google TV
- Helles, farbkräftiges Bild mit rund 1.300 ANSI-Lumen in den Filmmodi
- Kräftiger 30-W-Ton füllt ein 30-m²-Wohnzimmer ohne Verzerrung
- eARC gibt Dolby Atmos an Soundbar oder AV-Receiver weiter
- Autofokus und Trapezkorrektur richten das Bild zwischen 1,5 und 4 m selbst aus
- Mit 4,5 kg und Griff schnell in einen anderen Raum getragen
Cons
- Nativ 400:1 Kontrast: dunkle Szenen werden grau und verlieren Details
- Nur rund 1.300 statt versprochener 1.800 ANSI-Lumen in Filmmodi
- Lüfter mit rund 45 dB statt angegebener 28 dB in leisen Szenen hörbar
- Kein optischer Zoom und kein Lens Shift
- Dolby Vision macht dunkle Szenen dunkler, HDR nicht abschaltbar
