IRIS Ultra Max
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 JMGO IRIS Ultra Max ist ein heller Kurzdistanz-Laser für Bilder ab 120 Zoll und schnelles 4K-Gaming mit 120 Hz bei nur 5,5 ms Verzögerung. Im Filmmodus bleiben gut 4.300 Lumen, mit Blende F5.0 gibt es tiefes Schwarz bei 2.500 Lumen. Optischer Zoom, Lens Shift und Motor-Ständer erleichtern die Aufstellung. Der Haken: verschachtelte Menüs und wackliges Dolby Vision mit externen Playern kosten dich Zeit beim Einrichten.
Pros
- 4K mit 120 Hz an zwei HDMI-2.1-Eingängen, Latenz um 5,5 ms
- Gut 4.300 Lumen im farbtreuen Filmmodus, genug für Restlicht
- Dual-Iris hebt den Kontrast bei F5.0 auf 5.100:1 bis 8.600:1
- Optischer Zoom 0,88 bis 1,7:1 und Lens Shift ohne Schärfeverlust
- Motor-Ständer dreht 360 Grad, speichert bis zu zehn Positionen
- Google TV mit offizieller Netflix-App und kräftigem 25-W-Ton
Cons
- Dolby Vision von direkt angeschlossenen Blu-ray-Playern kommt nicht immer an
- Bildmenüs unübersichtlich, einfache Profile für Raumlicht fehlen
- Automatische Ausrichtung trifft an wechselnden Flächen nicht immer
- Lüfter rauscht mit rund 30 dB statt versprochener 26 dB
- Regenbogeneffekte bei schnellen Bewegungen für Empfindliche sichtbar
