The BenQ TK850 is a native 4K (3840 x 2160 pixels) projector that works well for many home golf simulator installations where you have enough room length and the projector will be ceiling-mounted on the center line of the screen.

What makes it great:

• Lowest-price 4K projector on the market that is suitable for golf sim use
• Optical zoom allows flexible mounting location
• 0" vertical offset and vertical lens shift up to 10" up or down means you have flexibility in mounting height without needing to adjust digital vertical keystone
• Conservative lumen rating of 3000 ANSI lumens is very bright - typically brightness will need turned below 50% in a room that has ambient light well-controlled
• Vertical keystone adjustment is VERY high quality, so you won't notice any image degradation if you do need to put some adjustment in (can mount up to a few feet higher than top of screen if desired, as long as the top of your enclosure won't cut off the light beam)
• Relatively light weight for easy ceiling mounting, even if you're anchoring the mount to a drywall ceiling
• When combined with a PC with an Nvidia graphics card like the RTX 2080, it supports almost any custom aspect ratio, including the elusive square image - so golfers with 8x8 or 10x10 screens can fill their screens
• Image detail and quality is extremely high, even with the smallest text labels in TGC 2019 and E6 Connect, and focus is sharp from corner to corner. Pixels are nearly impossible to discern even when standing close to screen.
• Quiet fan and good sound quality from built-in speaker
• Great price:performance ratio for 4K!

These units we're selling are factory refurbished in like-new condition, which make them even more affordable. Factory refurbs were typically returned within 30 days by home theater or gaming customers whose room or screen size didn't work for some reason, or a case of buyer's remorse, and come with a full 1-yr Factory Warranty from BenQ and at least 80% lamp life remaining (most of them are in the 90+% range). Normal lamp life is 4,000 hours, and lamp replacement is easy and affordable.

If you see the Add To Bag button above, we have these units in stock and will ship them via UPS ground within 1 business day. Sales tax will be added for Texas residents only.

Before purchase, please be sure to check this projector's throw distance with your screen size here. This is NOT a short-throw projector, but it has a reasonably short throw distance of 18'1" with a 9' tall screen, and works without shadows as long as you have a reasonably high ceiling and enough ball-to-screen distance (see the two example images of setup without shadows).

Full projector specs are here.

The Crimson AV JR3 is our recommended ceiling mount, and we keep it in stock here: Crimson JR3 universal ceiling mount

Please note that to run golf simulator software like E6 Connect and TGC 2019 in 4K with good frame rates and highest level of detail, your computer will need a high-end graphics card, equal to or better than the Nvidia GTX 1080 (the RTX 2080 is a good choice).

If you have any questions about whether or not this projector will work for you, please contact Ron, and he'll be happy to help you figure it out!
