Ever wondered why speakers, amplifiers, projectors etc. come with a slightly heftier price tag in India compared to their overseas counterparts? Well, part of the answer lies in our country's Goods & Services Tax (GST).

But here's the kicker: Don't let that GST input slip through your fingers! Especially when some of the products we supply carry a GST rate of 18% and 28%.

At AVStore, we provide you with a GST compliant invoice for every purchase.

The TK850i uses XPR technology to project 4K UHD resolution onto the screen with compatible content and features HDR10 and HLG compatibility to produce a wide color gamut for vivid colors. It outputs up to 3000 ANSI lumens of brightness and has a 30,000:1 dynamic contrast ratio to help produce details even in dark areas of the image, which is particularly useful for dark movie or video game scenes.

The projector has two HDMI inputs for connecting your digital HD devices such as a gaming console, Blu-ray player, or cable/satellite box. Its two built-in 5W speakers eliminate the need for external speakers if none are convenient. The TK850i includes an IR remote control for additional convenience.

Powered by Android TV

The included Android TV adapter keeps your favorite content easy to access. Enjoy over 5000 Android apps for quick access to movies, TV shows, live sports, news, games, music, and more. One-button access to Amazon Prime Video lets you watch Prime originals and a variety of 4K movies and shows quickly and easily. The included adapter also provides Wi-Fi connectivity for app access, Chromecast built-in, the Google Assistant, and Google Voice search.

XPR Technology Projects UHD Resolution

XPR technology combines image processing with the ability of the DMD's mirrors to shift at the microsecond level to allow each mirror to project two pixels per frame, creating a 4K UHD image on your screen from an otherwise non-UHD chip.

Enhanced Cinema-Optimized Tone Mapping Helps Preserve Dark Details

BenQ Enhanced Cinema-Optimized Tone-Mapping uses Dynamic Iris and Dynamic Black technology to help increase the perceived contrast ratio so you can see dark details more clearly. Dynamic Iris technology controls the amount of light via the optical system to augment contrast. Dynamic Black analyzes a scene's brightness levels to help optimize the light output and contrast, bringing out details in shadows and preventing bright scenes from washout.

HDR Brightness

HDR brightness helps keep the ideal contrast when projecting different image sizes and against various screen gains most commonly used in home theater to help ensure a greater contrast range and enhanced image quality when HDR Mode is activated.

Realistic Video Quality with HDR-PRO

HDR-PRO technology is engineered to enhance the 4K HDR viewing experience with a greater contrast range to bring out more detail.

10-Element, 8-Group Lens Array

The 10-element lens array is designed to provide greater light penetration for realistic image quality. The lenses use low-dispersion lens coatings to help minimize chromatic aberration to further enhance clarity.

Accurate Color and Image Integrity

With its single-DMD design to help avoid the alignment issues that arise in multi-panel systems, the TK850i provides sharp images and accurate colors devoid of artifacts, blur, shadowing, and interference patterns.

Custom Sport Modes

Sports Mode is engineered to provide realistic skin tones, balanced outdoor blues and greens, and warm wood grains for indoor sports action, while also accentuating the announcer's commentary and the roar of the crowd. The Sports Motion Enhancer (MEMC) helps eliminate jittery playback and blurry shadows by inserting 36 interpolated frames per minute in between individual frames for 60 fps videos.

Chambered 10W Speaker

A 10W chambered speaker helps enhance sound quality for gaming, movie watching, or streaming.

Bright, Accurate Color

The TK850i balances 98% of Rec.709 color accuracy and 3000 lumens of brightness for quality viewing of your favorite show or sport.

Flexible Adjustment for Screen Alignment

The TK850i features 1.3x zoom with 10% vertical lens shift to help provide hassle-free installation. Vertical keystone correction adjusts the image to help you achieve a properly squared image, countering the trapezoid effect that occurs when a projector is placed off-center.

USB Type-A 3.1 Gen. 1

The USB port can transfer data at speeds up to 5 Gbps. You can also project video, audio, and photos from your compatible USB drive directly without a cable or computer. You can also update the firmware of the projector via USB to help keep it operating at peak efficiency.
