ViewSonic LX700-4K UHD 3500 Lumens Laser Projector Designed for Xbox with 4.2ms Response Time, 240Hz Refresh Rate, 1.36x Optical Zoom, Dual HDMI, and HDR/HLD Support

This 4K laser projector delivers vibrant colors and 3,500 lumens of brightness. After three months of use—averaging about three hours a day, three days a week—I have not noticed any degradation in picture quality. Even on a regular painted light off-white wall, I can comfortably watch movies during the day at around a 120" screen size, with standard basement blinds closed. At night, with dimmed lighting, the projector displays excellent 4K quality on the same wall in my home. I imagine it would perform even better with an ALR or higher-quality screen. Overall, this is an excellent 4K projector for its price range, especially when available with occasional discounts. I haven’t used the higher-end model, but if you have a larger budget and plan to watch 4K content in bright ambient lighting or at much larger screen sizes, consider the LS901-4K, which offers a brighter 5,500 lumens (according to the specs). That said, the LX700-4K is still very watchable in medium room lighting, though you may notice some image fading unless the lights are dimmed. Keep in mind I kept the eco mode on for prolonged projector life and did not find need to disable it for more brightness.

I've had this projector for almost a month, and I really like it. I'm projecting on to a 110" screen in a dark room and am seated about 10' away. The 4K image is bright and sharp. I have an Amazon Fire TV Stick 4K plugged into HDMI 1 powered by the USB port. In HDMI 2, I have a Sony BDP-S6700 Blu-ray player that up-converts 1080p to 4K. I don't use the built-in speaker. I have a 2.1 speaker system that connects directly to the Amazon stick using Bluetooth and digital coaxial from the Blu-ray player. Using some generic active 3D glasses I also purchased on Amazon, I've watched most of my 3D movie collection and have to say the experience is fantastic, an almost movie theater experience. Setup was very simple after getting it mounted to the back wall of the room. I turned it on, focused, used the manual zoom to fit the pattern image to the width of the screen. I then used the lens shift to bring the image in line with the screen vertically. Adjusting the mount I got the image as level as possible. I then manually zoomed so no edge was inside the perimeter of the screen. Using the corner adjustment in the projector menu, I was able to bring any side or corner of the image that was outside the screen edge to exactly align with the edge. I have not had to re-do this since setting it up a month ago. I keep the power setting in Eco mode and it's still plenty bright. If you use the other power mode, the fan speed clicks up a notch. I've made a few color adjustments using settings I found on the internet. And with these settings, to my eyes, the white balance looks best in the "Cold" setting. Pros: Relatively low cost for 4K, HDR, 3D. Very bright. Very sharp. Very quiet. Color is excellent. Cons: Not the best black level (black is always dark grey). Built-in speaker is very basic. A bit of "rainbow" effect can be seen if you move your eyes rapidly.

I bought this projector in December, 2025, after much reading and reviewing of many other projectors. I chose this projector because I specifically wanted a 4K laser projector to replace my older Epson 1060. I also chose it because I do play XBOX and this is specifically designed to work with it. I used a generic, universal mount to attach it to the cross beam, upside down, as seen in the photo. It projects onto my 100" screen. I do not have the technical details about darkness levels or anything like that. I turned it on, turned the brightness level up a little, and have not made any other adjustments to the picture. I use cinema mode all the time and the blacks look black to me while all the other colors and image details really pop. The upgrade to 4K from 1080p is noticeable. The fan is much more quiet than my Epson 1060. It is not noticeable even at lower volume levels from my soundbar. The mono speaker works fine for things that can't run through my soundbar, but it is a mono speaker without much base - which is to be expected. At the time when I purchased this in December it was lower than the current price, which I thought was great for a 4K laser projector. I've not noticed any "artifacts" or blurring or orange flashes or tints as some other reviews have noted. The projector comes on with an instantly bright picture, no warmup. I do not watch sports so I cannot say how a football or baseball game will look on it. For watching movies, TV shows and playing HALO on, I am very happy with the image quality and performance. Hopefully this will continue far into the future since I no longer have to buy bulbs!

We purchased this to replace the projector for a church. The picture is clear and bright. 4K gives a clear image for presentations and videos.

The ViewSonic LS901-4K is a wonderful projector and honestly a hidden gem at this price point. My screen is a 125-inch custom-built ALR, and the projector is positioned 12'10" from the screen. The high lumen output of the projector offers amazing viewing in both bright and dark settings.

Unable to get a stable HDR connection. I've had multiple HDR projectors and had no issue, but with this new projector I am unable to get reliable HDR. I have a custom built gaming PC and an nvidia shield pro and both cannot setup a stable connection to the projector when HDR is enabled. It constantly stutters and color shifts. Both of these devices connect to the projector through the Denon AVR-X6700H 8K Ultra HD 11.2 Channel (140Watt X 11) AV Receiver. Again I've used another Viewsonic HDR projector without issue in this same configuration and an LG HDR 4k projector without issue. I tried swapping out all HDMI cables, etc. I've been holding out hope they would release a firmware update to fix this, but that still hasn't happened. So, IF THEY FIX HDR then I would give it 5 stars, but for a projector this expensive, having to disable HDR is unnacceptable.

Ich hatte von November 2013 an einen 3D fähigen Acer P1500 DLP Projektor, der 1080P kann an der Decke hängen und diesen ca. 20.000 Stunden im Einsatz ( mit 4 Lampen) Der Acer Projektor läuft immer noch einwandfrei, aber es gab Gründe für eine Neuanschaffung: Was musste der neue Projektor erfüllen: - Höhere Auflösungen (4K statt FHD) - Höhere Helligkeit (Kein Abdunkeln mehr in einem Raum mit Dachfenster bei normalem Lichteinfall) - Geringere Lautstärke - Geringerer Energieverbrauch Nachdem ich mich für den Viewsonic LX700-4K entschieden habe, und diesen seit dem täglich einsetze sind nun 3 Wochen vergangen. Punkte die ich hervorheben muss: Wer einen alten AV Receiver hat, an der die Zuspieler angeschlossen sind, und der dann das Signal an den Projektor weitergibt hat möglicherweise einige Probleme - was aber nicht am Projektor liegt, sondern an der Tatsache das ältere AV Receiver die notwenigen HDMI Standards nicht mehr unterstützen. Ich hatte vor 3 Wochen noch einen DENON AVR-1513 welcher das Signal einer Playstation, eines Apple TV 4K und von einem Fire TV 4K an den Acer P1500 fehlerfrei übermittelten, was Bild und Ton beinhaltete. Nach der Installation des neuen Projektors gab die Playstation keinen Sound mehr über HDMI aus, auch der Amazon 4K nicht mehr. Das einzige Gerät das fehlerfrei Bild und Ton ausgab war das Apple TV 4K - jedoch war das Limit immer 1080p, also FHD. Die Playstation habe ich dann behelfsmäßig noch über ein optisches TOSLINK an den Denon AV angeschlossen - dann ging wenigstens der Ton beim zocken wieder. So weit so gut oder soweit so schlecht..Bitte denkt daran wenn ihr einen Projektor oder ein anderes Anzeigegerät an eine AV Receiver anschließen wollt an das schwächste Glied in der Kette. Das mal unabhängig vom Produkt, aber relevant für den Alltag. Zum Projektor selbst: Installation war einfach - Ich habe ihn an der Decke hängen und projiziere auf eine ca. 80" Leinwand. Auf diese Fläche gesehen ist die hohe Helligkeit für meine Anwendung zu hoch - ich habe dazu direkt auf den Eco Mode umgeschalten. Wenn der Raum abgedunkelt ist, ist auch der Eco Mode fast noch zu hell. Vergleiche ich den neuen Viewsonic mit dem vorher installierten Acer Projektor hinsichtlich Helligkeit ist der Viewsonic im Eco Mode ca. 30 % heller als der Acer im Standardmodus. Die Lüfterlautstärke im Eco Modus ist beim Viewsonic ca. halb so laut wie der Acer P1500 (wenn man diesen ebenso im Eco Modus betrieben hat) Da ich den vorherigen Projektor und auch den neuen an einer Energiemesseinrichtung hängen habe, kann ich den Energieverbrauch ablesen. Der Acer P1500 hat mit einer neuen Lampe im Eco Mode ca. 220-230 Watt verbraucht. Der Viewsonic LX700-4K zieht ca. 145 Watt was ungefähr 40 % Ersparnis bei deutlich höherer Helligkeit und geringerer Lautstärke bedeutet. Also ganz grob fast fast 100W weniger Verlustleistung und damit weniger Wärmeentwicklung. Mit der Möglichkeit deutlich größere Leinwände zu bespielen hat man aus Sicht der möglichen erreichbaren Helligkeit noch viel Spielraum - auch für Views im freien. Wer einen Smart Projektor erwartet mit: - Netflix - Wlan - Airplay ... ist hier falsch! Die an den AV Receiver angeschlossenen Geräte sind hier Spezialisten und spielen ihre Fähigkeiten aus - der LX700-4K seine in Sachen Bild - und das macht er gut - auch wenn ein LX700-4K RGB hier wohl in Sachen Farben noch einen draufsetzen kann. Der LX700-4K mit seiner Weißlicht Laserquelle bietet aber ein sehr schönes Bild,ist sehr lichtstark und kann kalibriert werden! Von mir eine Kaufempfehlung. Bei Fragen dürft ihr euch gerne an mich wenden! Der Lautsprecher ist auch nur eine Notlösung, und ich bin der Meinung ein solches Gerät sollte primär für ein gutes Bild eingesetzt werden Update nach ca. einem Jahr Nutzung, 18.08.2025: Nun stehen 1008 Stunden auf dem Zähler. Bisher keine Ausfallerscheinungen. Keine Bildfehler, Lüfter ist immer noch angenehm leise.

Im using this projector as an theatre/tv in dark and lit room but I noticed that even in a dark room the the brightest from new and now (less than 2 months) is notably less. Also the crispness of the image decreased a bit. With images of reds being just wild and gross. Wasn’t the case when I first bought it. Would not currently recommend.

What an amazing device, it's super quiet and the image is extremely bright. Almost looks like an actually tv.

super, très lumineux. Image très bonne

Uso questo proiettore da circa 4 mesi e sono molto soddisfatto. La qualità dell’immagine è incredibile: i colori sono vividi, i neri profondi e la risoluzione 4K rende ogni dettaglio nitido. Il laser garantisce una luminosità ottima anche con luce ambientale moderata e la messa a fuoco è precisa e veloce. L’installazione è stata semplice e il menù è intuitivo. Ho apprezzato anche la silenziosità durante l’uso: la ventola è poco rumorosa rispetto ad altri proiettori che ho provato. Perfetto sia per film che per gaming, offre un’esperienza immersiva simile a quella di un cinema a casa.
