BenQ TH671ST 1080p Short Throw Gaming Projector

Higher brightness and the accurate colours, BenQ TH671ST, unveils the best reproduction of the colours to ensure they deliver the real-life images (with not just true colours BUT accurate ones.)

Known for delivering the unparalleled and unmatched picture quality as it comes with native and defaults F.H.D. (full H.D.) 1080p resolution with over 92 percent Rec.709 colour accuracy that ensures the images (and the motion content) throws out the real-life colours making you perceive you are seated into the middle of the scene.

Perfected with 3,000 lumens power and providing the powerfully-viewable higher native contrast ratio of 10,000:1 that NOT just gives the high-end delivery of the cinematic experience but boosts the avid gamers LOVE playing the games on selecting the highest of its graphical settings without blinking the eyes for long.

It does not matter to stream in the content with the best quality if it is DAY or NIGHT with that powerful lumens. Keep the blinds open or closed; you would not experience the degraded viewability at all.

Best crafted to enjoy the ultimate gaming experience and that too on the bigger-than-ever screen that is hard to have the level of enjoyment on the plain LED/LCD T.V. of any size.

As with the connectivity options, it got countless of them to expand and connect over multiple supported and the latest/modern devices without an alternation starting with HDMI, USB, VGA, Audio output (3.5mm), MHL, RS-232, and USB (service.)

So, hook either the latest available gaming consoles like Xbox 360, PS4s, Nintendo Switch, Google Stadia, and other such devices, including media players, P.C.s, Macs, and the smartphones to stream in your best content whenever you find the time to tune into watching with real-life experience.

Enough supportive refresh rate that enables this GAME-centric projector BenQ TH671ST does the best job in reducing the lag through its ultra-fast low input of over 16ms engineered to distribute the ultra-smooth gaming experience where it would bring NO motion blur, which is the killer of the creativeness and the enthusiasm to drop your interest into playing the game by matching with the maximum output offered by Xbox One X and PS4 Pro.

Go from projecting the image as much as 300” with the help of 1.2x zoom level, so to make it better, you understand the whole of its scenario as it would just take 5 to 6 feet to project over the content to gain over 100”.

It is all about the throw distances to set through to gain your optimum level of screen size given the fact you have been in the mode of turning your little room into a cinema OR got an outdoor gathering having over 50 to 100 folks excited to watch the favourite T.V. shows or just want to add in the music night into the party; gain the right throw distance, and it would take you to project over 300” of the screen (like we said earlier.)
