It has a brilliant output of 4000 lumens and a contrast value of 20,000: 1. The Optoma maintains its interactivity Ultra short throw projector through its Touch Beam finger-touch technology. It makes it particularly interesting for schools and also in the business sector. With an ultra-short distance projector, the presenter creates almost no shadows and not blinded by the light beam. To its projection ratio of 0.25: 1, the EH320USTi creates an image up to 100′ (corresponds to 2.54 meters) from a distance of 55 cm.


Interactive TouchBeam Function

The Interactive TouchBeam Finger-Touch technology integrated into the Optoma EH320USTi, which allows several people to work simultaneously. And all without a pen. With the technique, you can draw and rotate and zoom pictures. Several so-called touch points ensure a natural and catchy way of designing the lessons.

The Optoma EH320USTi offers Full HD resolution with 1920 x 1080 pixels in one format from 16: 9. In the so-called bright mode, the light output is bright 4000 lumens, and the contrast ratio is 20,000: 1. The Dark Chip3 from Texas Instruments is responsible for imaging technology. When displaying tables and fonts, they must stand out well from the canvas. Texts often shown, graphics explained, and tables are taught, especially in schools and businesses. The excellent image of the projector was convincing in an Optoma EH320USTi test.

The presentation of 3D content often used in the classroom and the business area. The Optoma EH320USTi is directly 3D capable, and over one of its HDMI Corresponding 3D content can display at the inputs. PCs, Blu-ray players, and gaming consoles can use as players. The image refresh rate in 3D mode is a high 144Hz, which ensures smooth image reproduction. It would best if you also had optional 3D shutter glasses. Not only in the school but also the design area, objects can be represented more vividly. If you put that 3D in class, it takes on a new dimension.



The Optoma EH320USTi is also conveniently positioned on the connection side – it contains the following interfaces: 2 x HDMI (1.4a 3D support), 2 x VGA (YPbPr / RGB), Composite, 2 x Audio In 3.5mm, Audio Out 3.5mm, VGA Out (together with VGA2), RJ45, RS232, USB mouse control/service, 12V trigger, mic in, USB-A power and 3D-Sync.



Control by an administrator makes sense, especially when several devices are out of date. It can choose between three options: First, it can be via RS232 Taxes. It is also AMX compatible, and the associated Dynamic Discovery protocol allows easy installation with AMX control systems. The third control option controls via LAN. The administrator can use a compatible RoomView software to switch on and off, monitor, and manage many projectors simultaneously via the web interface. Emails can also send automatically if, for example, the lamp needs to replaced.


Save Energy

In this context, the so-called ECO-AV-Mute function. The presenter can then draw the listener’s attention again by hiding the image. As a side effect, electricity consumption is also reduced by around 70%. In addition, this extends the life of the lamp. If the projector accidentally turned off, you can turn it back on using the Quick Resume function.

Also on board is the Eco + technology, which has high contrast, extended Lamp life, and energy-saving features combined. Overall, this ensures lower power consumption, which is also supported by unique lamp modes, leading to longer lamp life. Ultimately, the automatic shutdown feature also saves energy: the projector shuts down after a set time when it is not in use.


Wireless Connection

The projector has a function of an optional connection to a signal source. Connect the WPS wireless adapter (sold separately) to display presentations and videos directly from your laptop, personal computer, or mobile phone.
