What can an ultra short throw projector be used for?
An ultra short throw projector can be used both at the office and in the home. Its name, ultra short throw, refers to the fact that the throw distance between the projector and the wall it will project on, is extremely short. Depending on how large of a picture you want on the wall, this ‘throw’ distance will vary between 4 and 15 inches.
Ultra short throw projectors can be used for work presentations, slide shows, or as a home media venture.
What features to consider while looking for an ultra short throw projector?
When looking for an ultra short throw projector to purchase, it’s important to know what all of the specifications mean. Here is a guide to the terms that you will see on the package together with their explanations.
To understand the throw ratio, you need to understand a bit of math. The throw ratio is how far the projector has to be placed away from the screen or wall in order to produce an image. The ratio starts with a screen that is one foot wide and then you can do a bit of math to understand the distance needed for the actual size of the image.
Traditional projectors will have a throw ratio of 1.5, which means that to project onto a 10-foot screen, you will need to place the device 15 feet back.
10 x 1.5 = 15
Ultra short throw projectors have a throw ratio less than 0.4. The LG HF85LA has a throw ratio of 0.19. For this device to project onto a 10-foot screen, you will need to place it 1.9 feet back
10 x 0.19 = 1.9
You can also get short throw projectors, which have a slighly larger ratio than ultra short throw ones, but still less than a traditional projector.
Screen size is an important consideration when buying an ultra short throw projector. Most screen sizes will be between 60 and 100 inches wide. Be sure to measure the location that you want to project an image upon to ensure that the projector you purchase will work for that space.
This is quite a technical term. Some projectors show images through LCD (Liquid Crystal Display) panels. This technology is fairly straightforward and it is easy to adjust the contrast and brightness with such projectors.
Other projectors use DLP (Digital Light Processing) technology. This uses tiny mirrors that reflect images. Advantages include high contrast, light weight, and a lack of pixilation.
It’s important to know the maximum size that an image can be displayed on a screen from an ultra short throw projector. This number appears in the native resolution, and it measures the number of horizontal and vertical pixels. The Optoma GT5500+, LG PF1000UW, and LG HF85LA have resolutions of 1920 x 1080 while the LG Electronics PH450UG has a smaller resolution of 1280 x 720.
Nobody wants to have to squint to see a movie, which is why the level of brightness is so important. For ultra short throw projectors, this is measured in lumens. This can range from the LG Electronics PH450UG which has a brightness level of 450 lumens to the Optoma GT5500+ with its 3500 lumens.
Another math term here. The contrast ratio refers to how much brighter a white image will appear on a screen than a black image. The higher, the better. The Optoma GT5500+ has the lowest contrast ratio on this list at 25,000:1. The LG PF1000UW and the LG HF85LA have the highest contrast ratios at 150,000:1.
If you’re not particularly tech savvy, then it’s important to have a warranty for your product. All of the products on this list have a one-year warranty, which is the industry standard. If you are worried about any future repairs with your projector, there are optional warranties that you can purchase.
The more you spend on an ultra short throw projector, the more features you should get. For example, the LG HF85LA has a laser lamp with a life of 20,000 hours. The Optoma GT5500+ has a 3D-sync port which is really cool as you can use 3D glasses. This is perfect if you’re into immersive gaming.
One important feature to look for is wireless compatibility. Even if you don’t always use wireless features at the moment, chances are you will in the future, and it is much easier to connect two devices wirelessly than fiddling around with a bunch of cables and wires.
However, don’t feel pressured to purchase a projector that has a bunch of fancy features. If these are things that don’t interest you, or you have no use for, then there is no point in spending extra money on them.
What are the advantages over other types?
Ultra short throw projectors have the unique advantage of taking up a lot less space than traditional projectors. While they are relatively small in size, you don’t need a large room, shelf, or ceiling mounts. This makes having an ultra short throw projector a lot more versatile. They are usually quite easy to set up and if they have wireless capabilities, then can be moved from room to room with ease and convenience.
If you are using an ultra short throw projector in the classroom or at the office, you can set it up and not have to worry about where you walk. Gone are the days of hastily walking through the image as you cross the room. Likewise are the tripping hazards of all the cables.
While ultra short throw projectors are slightly more expensive than traditional projectors, they are actually relatively affordable. The benefits that they provide are generally worth the bit of an extra price bump, especially if you know you will be getting a lot of use out of one.
What are the basic precautions when using an ultra short throw projector?
Be sure to treat your ultra short throw projector as you would any other electronic device. Do not pour water on or near the projector. Leave ample space around the fan and ventilation holes so that the unit won’t overheat. Be careful when handling the projector and don’t shake it or drop it.
An ultra short throw projector can seem like a novelty toy, but it is a sophisticated piece of technology and should be treated so.
