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 BenQ TK705STi ist ein 4K-Kurzdistanz-Beamer, der 100 Zoll aus knapp 1,8 m an die Wand wirft. Er passt in kleine Wohnzimmer, zu Konsolenspielern und zu allen, die Netflix ohne Stick wollen. Seine Farben sind ab Werk stimmig, der Input Lag ist kurz. Der Haken: Schwarz bleibt im Dunkeln grau, und ohne Zoom stellst du die Bildgröße nur über den Abstand ein.
Pros
- Kurze Distanz: 100 Zoll aus knapp 1,8 m Abstand
- Ab Werk farbtreu, Rec.709 zu 98 bis 100 % abgedeckt
- Input Lag von 9,6 ms in 4K mit 60 Hz
- Google TV mit offizieller Netflix-App in 4K HDR
- Hält die Helligkeit: 3.060 Lumen im hellsten Modus
- USB-C mit Bildsignal und 30 W für Switch oder Steam Deck
Cons
- Nativer Kontrast nur 570:1 bis 705:1, Schwarz wirkt grau
- Kein optischer Zoom und kein Lens Shift
- 4K nur bis 60 Hz, VRR fehlt
- Lautsprecher fast ohne Bass, laut gedreht scharf
- Fernbedienung ohne Tastenbeleuchtung
Der Nebula X1 ist ein transportabler 4K-Laser-Beamer, der Heimkino-Bild und automatische Aufstellung vereint: rund 2.100 bis 2.600 ANSI-Lumen reichen fürs Wohnzimmer mit Tageslicht, Gimbal und Zoom richten das Bild in etwa zehn Sekunden aus. Er taugt für dich, wenn du ohne festen Heimkinoraum 100 Zoll willst. Der Haken: graues Schwarz, Surren in leisen Szenen und eine träge Google-TV-Oberfläche.
Pros
- 2.100 bis 2.600 ANSI-Lumen in farbtreuen Modi, genug fürs Wohnzimmer mit Tageslicht
- Gimbal, Autofokus und Trapezkorrektur richten das Bild in rund zehn Sekunden aus
- Motorzoom mit 0,9 bis 1,5:1, 100 Zoll aus 2 bis 3,3 m
- Pixel-Shift-4K bis in die Ecken scharf, Ausleuchtung 90 bis 96 %
- Google TV mit offizieller Netflix-App in 4K und Dolby Vision
- 40-W-Lautsprecher füllen auch größere Wohnzimmer, 18,3 ms Input Lag im Spielmodus
Cons
- Schwarzwert mit Grauschleier, nur 1.400:1 On/Off und 250:1 ANSI
- Lüftersurren mit 27 bis 32 dB in leisen Szenen hörbar
- Google TV mit 2 GB RAM reagiert träge, Ersteinrichtung bis zu einer Stunde
- Gespeicherte Raumeinstellungen und Leinwanderkennung arbeiten nicht immer zuverlässig
- Nur 60 Hz: kein 120 Hz, ALLM oder VRR trotz HDMI 2.1
