Most users who are looking for new projectors aim to improve their audiovisual experience at home, although of course there is also a segment dedicated to offering presentations in the workplace or study in a correct way . Today the protagonist of the analysis points precisely to that group and is called Epson EB-680 .
Epson EB-680 is an upper-mid-range projector that features a brightness level of 3,500 lumens and XGA resolution , while its small footprint design allows projection of large images from a very short distance with less shadows and glare. Here we go over everything this team has to offer.
A screen smaller than average
Reviewing the main specifications of the projector, it is necessary to indicate the use of a traditional 3LCD technology that makes it possible to appreciate high quality images with equally high white and color light emission levels to achieve vivid colors and bright images that are up to three times above the market average, even in broad daylight.
With a projection distance that only needs 40 cm, Epson EB-680 can generate a total screen size of up to a maximum of 93 inches , which a priori is less than the number seen in other equipment of the same brand or of the competition , but that ultimately should also be sufficient to clearly show the images to colleagues in the room.
The output resolution of the computer is XGA, which means a ratio of 1024 x 768 pixels with a native 4: 3 aspect ratio. This makes it clear that it will not be the most comfortable model for playing videos, movies or games at home, but rather aims to display documents and office presentations in a more formal way.
Also, as indicated above, it is possible to appreciate a very good general brightness through a maximum of 3500 ANSI lumens . This does not require completely darkening a room so that images or text can be seen clearly.
Some additional benefits
Epson EB-680 has the advantage of reducing the general costs of maintenance and replacement of parts, since for example its lamp promises a useful life superior to almost all the projectors on the market with a maximum of 10 thousand hours with the ecological mode activated (or half in normal use) .
On the other hand, among its additional functions, the presence of a split screen is appreciated to show two contents simultaneously without sacrificing quality. The moderator function allows teachers to always be in control choosing what content to show at any time.
Finally, although they are not included by default with the purchase of this unit, there is availability for an optional wireless connection to display content from smart devices and Google Chromebooks through the iProjection application, as well as being compatible with a document camera to easily present to all class images and 3D objects.
Connectivity, sound and comparison
To conclude with the benefits of Epson EB-680 we can mention the integration of a 16W power speaker to reproduce multimedia contents without using external audio equipment, while its generated noise level has an average of 35 dB (28 dB in eco mode).
For its connectivity, there are a total of three HDMI ports as well as another three D-Sub for older computers. There is also two USB 2.0 ports for external storage units, Ethernet for synchronization with the local internet network via cable, a classic 3.5 mm headphone output, composite video input and another audio input (R&D).
In case you are looking for a projector that is more effective to be able to use it for leisure activities, there are other “Premium” models that are better adapted such as the Epson EH-LS300B with support for Full HD image output in relation to 16: 9 aspect ratio and support for screens up to 120 inches .
