Product Features:

1.Brilliant color technology, vivid picture displaying

TI’s newest DDP4421 chipset is used, three technology advantages are provided:

Ø Picture quality is more detailed;

Ø More powerful compatibility of resolution;

Ø More powerful compatibility of 3D video. Brightness and color expression are improved and more fluent video effect is provided.


Blue ray 3D directly reading, DLP Link 3D and IR 3D technologies are supported. With 3D glasses, users can enjoy 3D movies and most authentic 3D visual feeling is provided to education and business users.

3.Automatic off with no signals

If there is no signal input in a designated time period and with no operation, the projector is shut off automatically, intelligent and environment friendly and saving the energy. (When the parameter of energy saving mode is set to be “0”, the projector will not be automatically off).

4.USB display

Contents in USB disk can be displayed by USB wireless adapter.

5.Power-off protection function

The optimized heat dissipation design of the lamp host enables the lamp heat can be cooled fast naturally when the power is off and there is no fan, damages from heat to the lamp is decreased. Once the power is on again after sudden power off, the project detects the lamp temperature and internal temperature of projector. If the temperature is too high, the fan is turned on automatically until the internal temperature is decreased to a suitable level, ensuring the safety of projectors and prolonging the lamp life.

6.Upper cover opening, fast lamp replacing

The upper opening system for the lamp replacing makes maintenance of projector more convenient, especially for the ceiling installation in classrooms, decreasing the overall cost of users and saving the education resources.

7.One-key switch for application mode

Humanized design, different mode is switched by pressing one key, fast and convenient.

8.Double layer filter for dust protection

Double layer filter can filter the dust of different sized; bigger ones will be filtered by the outside filter and small ones will be filtered by the inside filter, the dust protection result is improved greatly. Such design not only improves the filtering result, but also ensures the ventilation of cooling air flow and the normal operation of projector.

9.Fast on/off function

The image is projected after the equipment is on for three seconds. Automatic heat dispersion and protection is on when the machine is turned on again after an abnormal power off, the life of the machine is prolonged; no need to wait after the machine is turned off and the power cable can be removed immediately.

10.Energy saving and environment friendly

Standby power consumption is less than 1W which can save more resources for users.
