The LK953ST is a rather interesting laser projector. It is perhaps the most expensive of the 5,000 lumen laser projectors focused on in this education report, but there are some good reasons for that. This 5,000 lumen laser projector sports DLP technology and uses pixel shifting to achieve 4K UHD.
BenQ traditionally promotes that they give great focus to producing the best color. I have to generally agree. Right out of the box, BenQ projectors seem to have better color than many other DLPs (most 3LCD and LCoS projectors are generally known for better color than many DLPs as well). Still, great to have a projector that starts out with a goal of excellent color, and delivers on that, which makes the LK953ST suitable for many applications beyond basic presenting including digital signage, photography and video production museum use, and scientific (i.e. false color, other color critical applications). Several of the modes offer very impressive color with little or even no adjustment at all. It also has a DICOM SIM. mode for medical films.
You will be hard-pressed to find another projector in the general price range endowed with more inputs and outputs, including 3 HDMI inputs (one is HDCP 2.2), and even an HDMI out. With the HDMI out, two projectors can be easily stacked for double the brightness, without any extra switching. Just connect the two and set the menus correctly! Count that as a real plus for auditorium use, signage, museums or even large lecture halls at universities. The 5,000 lumens of laser power from a single LK953ST should satisfy most other university rooms without stacking. No surprise that the LK953ST has both wired LAN networking and HDBaseT for longer distances! There’s also analog VGA Computer In and Out, an RS232 connector, two USBs and a 12 Volt Trigger, and even a wired remote connector for those special setups (like rear screen usage). A wireless presentation system is optional.
This is a short throw design with a very modest 1.1:1 ratio. Most projectors need to be at least 9.5 feet back from a 100” diagonal screen, whereas this projector can sit as close as 5 feet 10 inches. I point this out so as to not confuse short throw with very short throw (very short throw projectors for that sized screen usually sit 2.5 – 3.5 feet back, and therefore will work on telescoping wall mounts). The LK953ST could use one of those mounts with an 72” diagonal screen or less, but probably no larger. The projector does have quite a bit of lens shift – both vertical and horizontal, for good placement flexibility.
The ST design makes it a bit unusual, but overall, the BenQ LK953ST is exceptionally capable, has good color, and is fairly well-priced. Certainly, there are other 4K capable projectors (including some 1920 x 1080 x2 pixel shifters) priced less for 5,000 lumens, but the overall value proposition looks good. The full review of this BenQ projector should publish by mid-April.
