Stunning Gaming Projector
After speaking to a Projector retailer, i decided to go for this gaming projector as i wanted to get the full potential out of my PS5, I wasn't disappointed, the image is absolutely stunning. There are a few minor details that i didn't like but can live with. PRO's - Image quality amazing for both gaming and movies 3 gaming settings, RPG, FPS,SPS Fan noise Low Built in APPs for streaming Movies Easy to set up once in the correct position Option to pay over 6/12 months Can project upto a 300" screen CONS - NO X,Y keystone for changing screen size, which means you need to get the projector in the exact position to match you screen which can be tricky. I had to buy a ceiling mount as the throw projects at an upward angle and not straight Speaker volume not great but i have a small room so is enough for me, a larger room would need a soundbar. Turning off the projector takes about 2 mins to power off. The Price is high but you won't get a 4K 90" Tv for less than £1100 Would i recommend this projector? YES, Although it has some cons, they don't outweigh the pro's. Before you buy i recommend that you study the projector scale so that it can be positioned in the right place as i said you can't change the screen size through the settings, screen size is determined from the distance you have projector from the screen

Your in-home cinema experience is ready to go in moments
As a long-term ‘4K refusenik’ I decided to take the plunge with this projector in combination with a 100-inch screen. I'm very glad I did. This projector was very easy to set up. The keystone adjustment ranges made it easy for me to position the projector exactly where I wanted it. The brightness was impressive. The focus was simple to get to pixel sharpness in moments. It recognised my computer input easily and was able to show very many possible resolutions I might want to use.

wont load iplayer
good picture and reasonably bright but unfortunately has two annoying issues: 1) keep telling us to optimise for gaming mode and that holiding ok for 2s will stop it asking but then the same issue comes back every time you turn it on. 2) the chromecast that is built in won't allow bbc iplayer to be installed.

Amazing value, fantastic picture.
I bought this as a main screen for the house. We mostly watch TV on devices and projector is used for movies and video games, which we only really do at night. The picture quality in a dark room is astounding, even projected directly onto a white wall. I wont bother getting a screen. Having worked in media for 20 years I wasn't overly hopefully and bought this as a "proof of concept" to see if a projector would work for us. Happy to say I am blown away. Even at a 2.75m wide image, quality is superb. In a lighter room (curtains drawn but with plenty of ambient light during day and a window without curtain in adjoining room) the image is still bright enough for games or regular TV. Dark images suffer compared to using it in a dark room though. Setup was trivial. About as plug and play as it gets. Unnoticeable input lag for games. If you intend to use this mostly at night or in a dark space, you will be extremely impressed. Top 5 lifetime purchase. 11/10. Would purchase again.

The best projector under 2k you can buy for roof mounting
I buy a lot of projectors. I use them exclusively for TV and cinema in two rooms of my house and I've tried quite a few of the ones on Amazon before settling. While this isn't a projector I kept it certainly was one I wanted to. The picture is really massive for the throw distance and the best quality of all projectors I've seen and tried. Its fan noise is comparably very quiet and the overall look and feel is premium and brilliant. The reason I didn't keep it is that the throw angle means it needs to be roof mounted. Its possible to have it on a stand by severely angling it (and I was very tempted), or by having a much smaller picture and putting it on a table low and in front of the wall but you lose a lot of the reason for buying it. Correctly fitted this will fill an entire wall with gorgeous quality picture. If you can roof mount then I wouldn't hesitate to recommend this.

Richer Sounds poor and product faulty within 5 months
5 months old and now when I plug it in and it won't power up. I've changed the fuse and checked the plug and socket. There's just no power. Richer sounds say as bought through Amazon need to go through them and out with the 30 days. The worst service and would never buy with Richer Sounds especially through Amazon again. I’m left with nowhere to turn just now

Garage cinema
Bought this for my small garage cinema room and its awesome, been using it for over 6 months now for both 4k movies and Xbox gaming and has been flawless, found the price to be great for what it can do and kids love sitting watching TV shows and movies.

Does not support arc
I have returned this product, not because it is a bad product. I set it up and it works great, however it does not support Arc audio where amazon says it does. The projector itself is great though and I have returned it to swap for the tk710 that does support arc.

Si vous n'avez pas besoin d'un éco système ave style android TV, etc, que vous pouvez d'ailleur acheter à part pour une poignée d'euro, il est presque parfait, déjà j'avais un Benq 1070W, toujours fidèle mais il faisait du bruit et pour une grande image l'UHD c'est mieux, la presque plus de buit, on l'entend à peine, l'image est nette et très lumineuse, attention quand même c'est pas une télé, sur 3 mêtres de base si vous voulez des noirs plus profond il faudrai éteindre les loupiottes, tout petit bémol, pour les film 3d il ne switch pas forcément en 1080p en SBS ou TBB, idem pour les jeux venant d'un ordinateur, j'ai pas encore bien regardé si il y a pas un moyen, car sur le Freebox Pop il faut revenir sur le menu de base et se refere le réglage manuellement, sur PC c'est plus pratique en deux tois clique, en R/P c'est impattable, je n'ai pas vue non plus d'option de compensation de mouvement tellement à la mode sur les dernières télés, l'effet filmé avec un camescope mais super fluide, après idem pour mes sources, c'est pas du bluray forcément en mode HDCP. Pour le son, sauf pour le voyage ca sert pas à grand chose, autemps mettre son enceinte connectés dessus. J'espèrere qu'il me fera 10 ans comme l'ancien quitte à remplacer la lampre pour 150€ max si perte de luminosité, bravo BenQ quand même, ah oui la télécommande non rétroeclairée, arrrgggggg :)

Absolument incroyable ! Bluffant ! Qualité de l'image est irréprochable, la qualité du son est très correcte !

Ich habe den Beamer erst seit einem Tag im Einsatz, es folgt sicher noch ein Update. Bis dato kann ich mich aber allen Rezessionen auf YouTube etc. Anschließen (The Hook Up, hat eine sehr gute und aktuelle Zusammenstellung hierzu gemacht). Tldr: genialer ShortThrow Gaming Beamer für einen angemessenen Preis. Positiv Erstklassiges Bild bei „nur“ 2200 ANSI Lumen Grandioser Kontrast Kein merklicher Input lag beim Gaming Super UI des beigelegten BenQ Sticks Für mich war es wichtig das es ein kurzdistanz Beamer wird, was einen deutlich breiteren Einsatz in allen Räumen ermöglicht Negativ Beamer / Lüfter Geräusche wirklich merklich im Vergleich zur Konkurrenz - jedoch nur bei 4K, bei 1440p/120Hz zB deutlich besser Neutral Größe ist zwar marktüblich jedoch aufgrund der Aktualität hätte ich mir etwas noch kompakteres gewünscht.

Nadie lo menciona, no siquiera los fabricantes pero este proyector permite utilizar lentes activos para imágenes en 3D. Baja latencia para jugar en línea, resolución 4K real, muy buen contraste qué permite una imagen clara en ambientes con luz. Es de corto distancia lo que me permitió instalarlo en el techo y lograr una imagen de 120" en escasos 3 metros. Soy un fanático de pe,islas en 3D, cuento con una tv pero sabiendo que un día dejara de funcionar decidí comprar este proyector que es algo caro pero no defrauda. La salida de audio es buena, pero yo utilizo la salida digital del reproductor para mandar el audio a un equipo y el resultado no tiene comparación.

Après plus d'un an d'utilisation, la qualité d'image n'a pas bougé. Le capuchon de protection de la lentille s'est casse très (trop) rapidement, du coup je ne peux plus la protéger quand le le range. Il me reste plus qu'à trouver une solution pour le fixer discrètement au plafond.
