Why these made the list
The pool started as every BenQ projector in the catalogue, which came to 3 priced listings. Because the pool holds fewer than a dozen entries, this guide covers all 3 and drops none. Each pick was chosen against the same rules: resolution tier, lumen range, throw type, and smart capability, all taken from the seller's listing data. Prices shown on the page are live and read at the time the page loads, which is why the text never quotes dollar amounts. No one on the team has tested these projectors; the comparison is based on the stated specifications, the maker's published information in the names, and the catalogue data.
Things to weigh before buying
Resolution: 4K versus 1080p
The pool splits into two resolution tiers. The W4100i and TK710STi are listed at 4K, while the TH671ST is listed at 1080p. If your content and sources are 1080p, that tier is enough; if you stream 4K material, the 4K tier handles it directly. All three models sit in the 3000 to 5999 lumen brightness range, so brightness alone does not separate them.
Brightness: the 3000 to 5999 lumen class
Every pick in this list is rated between 3000 and 5999 lumens, the range stated in the listings. That puts them in a similar brightness class for rooms with some ambient light. The two 4K models are listed at 3200 lumens, and the 1080p model at 3000 lumens, so differences in brightness between picks are small. Choose on resolution and throw distance before brightness.
Short throw versus standard throw
Two of the three picks, the TK710STi and the TH671ST, are short throw models, meaning the listing states they can sit close to the screen and still fill it. The W4100i does not state a throw type, so for a tight room the short throw picks are the safer choice. Short throw also helps in living rooms where the projector has to share the space with furniture.
Smart features: what built in means here
Only the W4100i is listed with smart capability in this group. A smart projector is designed to run streaming apps without an external device, though the specific app support is not stated in the pool. The TK710STi and TH671ST do not state smart features, so plan for an external streaming device with those two if you watch internet video.
HDR and color: reading the model names
The W4100i and TK710STi both state HDR in their model names; the TH671ST does not. A projector that lists HDR is designed to accept high dynamic range signals, which matters with 4K sources. Dolby Vision is one HDR format, and Dolby describes it as dynamically optimizing the image based on the service, device, and platform. The pool does not state which HDR formats these three projectors support, so this guide does not claim Dolby Vision or any other specific format for a particular pick.
Connectivity: HDMI and USB
Sources reach a projector through HDMI, and the HDMI organization's specification defines the standard as well as optional gaming features such as Variable Refresh Rate and Auto Low Latency Mode on newer versions. USB ports are also common for media playback, and the USB Implementers Forum maintains those standards. The pool does not state which HDMI version or which USB standards these three projectors use, so confirm the ports on the listing before you buy.
Questions
Which BenQ projector in this list has the highest resolution?
Two picks are listed at 4K: the W4100i and the TK710STi. The TH671ST is listed at 1080p. If 4K is a requirement, either of the 4K models matches it; the W4100i adds smart features, and the TK710STi adds short throw.
Do all three projectors have the same brightness?
All three sit in the 3000 to 5999 lumen range stated by the listings. The W4100i and TK710STi are named at 3200 lumens and the TH671ST at 3000 lumens, so brightness is similar across the group.
What does short throw mean for these projectors?
A short throw projector is designed to produce a large image from a short distance between the unit and the screen. The TK710STi and TH671ST are both stated as short throw; the W4100i does not state a throw type, so it is less certain for tight rooms.
Which pick has built in smart features?
Only the W4100i is listed with smart capability in this group. The TK710STi and TH671ST do not state smart features, so with those two you would connect an external streaming device such as a stick or set top box to watch app content. If built in apps are important, the W4100i is the only pick that matches.
Is HDR available on all three?
The W4100i and TK710STi both state HDR in their model names. The TH671ST does not. The listings do not specify which HDR formats are supported, so this guide does not claim a specific format such as Dolby Vision.
