“Regular,” “Short Throw,” “Ultra Short Throw” are terms to define how far out from the screen the projector has to be to project a suitably clear image. The traditional projector is required to be positioned a considerable distance away from the screen. However, this led to concerns about shadows obstructing image from the screen, and the obvious fact that projectors could not be used in spaces where there is inadequate room.
Best Short Throw Projector Complete Guide
In the search for a solution to the limited-space problem, the manufacturers birthed the short throw projectors first, and after much improvement moved on to Ultra Short Throw projectors. In the table below, we compare projectors in the three throw distance groups.
|Throw Distance Group||Throw Ratio||Projected Diagonal Image||Screen-Projector Distance|
|Regular||1.5:1||5 feet (60 inches)||7.5 feet|
|Short Throw||0.6:1||5 feet (60 inches)||3 feet|
|Ultra Short Throw||0.37:1||5 feet (60 inches)||1.4 feet|
Before we discuss the benefits and detriments of short and ultra-short throw projectors, let us enumerate instances where they would be necessary.
- Small Home Theaters
- Trade Show Booths
- Small Conference Rooms
For use in a small space, it is important to look out for projectors with quieter fans are they are more desirable.
Short Throw and Ultra Short Throw Projectors: Good and Bad
- Can be placed only a few feet from the screen, which is great for owners/users of small spaces
- Prevents unintended manipulation of the equipment, for example kids in a classroom
- Prevent the common complaint of shadows obstructing projected image on the screen
- Elimination of the common complaint of discomfort resulting from light, from the projector, shining in a presenter’s face
- Elimination of unclear, out-of-focus images that result from adjusting the focus at a distance
- Limited flexibility during setup
- Most require a fixed distance between the top of the projector and the bottom of the screen, referred to as a fixed offset
- Lack of zoom and fixed lens are common configurations
The brightness rating of projectors is measure in lumens. As a rule of thumb, it is recommended to go for projectors that have high brightness ratings. This is because; a brighter image will still be visible in a space where there is ambient lighting, say the lights are on, or it is difficult to restrict daylight from trickling in.
To understand the relationship between image/screen brightness and ambient lighting better, try reducing the screen brightness of your smartphone while you are outdoors and notice the visibility of images in your screen reduce.
Throw ratio refers to the ratio of the width of the projected image to the screen-projector distance. The throw ratio and the screen-projector distance are directly proportional, which means that as the throw ratio decreases, the screen-projector distance decreases as well.
Since, the conventional display of the throw ratio is “X:1,” for example 1.5:1 (the throw ratio for regular projectors), it is possible to ditch the ‘colon’ and ‘1’ in the depiction and refer to just the ‘X’ value. Therefore, for regular projectors, the throw ratio is 1.5. The best short throw projectors, accurately referred to as ultra-short throw projectors are capable of an impressive throw ratio of as low as 0.38.
The lamps or light bulbs on the inside of DLP (digital light processing) projectors have a life cycle. In addition to needing replacement every occasionally, they also tend to lose their brilliance over time. LED and/or Laser systems are preferable in that they do not need replacement nor does the brightness level degrade over time.
With that said, DLP projectors have certain advantages in image processing and are usually the most cost-effective choices, so if you are stuck with making a DLP projector choice, do not sweat it. The lamp life cycle of top-grade DLP projectors is 5000 hours anyways. On average, that would get you about half a decade of usage before the lamp needs changing. To check degrading brilliance over time, premium manufacturers routinely include software optimizations in their models to limit the wearing out effect massively.
Best Short Throw Projectors Reviews
The HT1085ST is primarily a home entertainment projector. With a throw ratio of 0.6, it fits well into the short throw projectors click. Where the HT1085ST shines forth is in its exquisite image quality and superb brightness levels, which allow it to outperform the competitor and bag the illustrious best short throw projector spot.
On top of the HT1085ST’s offering is the BenQ Kit. It is BenQ’s answer to the WirelessHD feature spotted in premium Epson products. What the kit does points down to convenience. The Kit includes a transmitter that serves as a hub in that it receives video streams from one or more sources, and then transmits received media content (video and sound) to the projector wirelessly. Everything is seamless; it helps streamline connectivity, and no doubt eliminates the ‘clutter’ problem that is always the case with wired connectivity on standard projectors.
BenQ goes one step further to bring it home, the receiver unit (another tool in the kit) is a standalone device. This is unlike on Epson projectors where the receiver unit is built into the projector. To appreciate this feature, it is important to understand how the receiver unit works. The receiver unit receives video signal from the transmitter and then modulates the signal so it can be interpreted right by the projector’s internals. BenQ’s receiver unit sports a HDMI port, through which you can connect the receiver to virtually any projector with a HDMI port using a HDMI cable.
Flexibility is not all to love about the BenQ Kit. The official range is capped at 100 feet in a line of sight connection. In our testing, we placed the transmitter on one floor, and then we placed the projector and receiver on the floor below. The distance between them was 30 feet, and the video content stream seamlessly without glitches. That was terrific performance, which demonstrated flexibility, reliability, and convenience all rolled into one amazing package.
The HT1085ST has a built in audio system—a 10-watt mono speaker. It is basically the standard on major models. Sound quality is decent, and the volume can fill up an average-sized living space. For better sound quality, you would have to connect a dedicated audio system, which is pretty much a given on all projectors in the market.
The HT1085ST has an exuberant image quality. Delivery of everything from color quality, skin tones, to shadow detail was top-notch. Rainbow artifacts were also reduced to a bare minimum. Rainbow artifacts, which display as flashes of red, blue, and green, are unintended consequences of the DLP technology that plague DLP projectors. Eliminating them is out of the question, but limiting their occurrence is possible, and that is what the HT1085ST does well.
Brightness levels bolstered image quality, and it is possible to lower or increase brightness using any of the available brightness presets, including the Eco mode.
3D support is available on the BenQ HT1085ST. 3D image quality was splendid in our tests. Crosstalk and motion artifacts were absent, and motion was smoother than on most 3D projectors. It offers 3D support, so you will need a pair of 3D glasses— such as these 144-Hz DLP-Link glasses found on Amazon.
