Polar Z4 Aurora comes with two USB ports (one USB 2.0 and one USB 3.0). This function is very practical for smart projection. Users can rely on the network to obtain video and other resources. Without a network, With the expansion of USB external devices, many functions can still be achieved. When the user connects a USB device, the Z4 Aurora automatically recognizes the storage device and jumps to the external device operation menu for the user to select and operate. The picture above shows the real effect of the Z4 Aurora with demonstration. The Z4 Aurora supports 3D video playback. With the 3D function of the host computer and wearing random 3D glasses, you can feel the visual feast of the 3D movie.
4K/1080P local video projection real shot effect, the performance is very amazing.
In the test of the external storage device of the Z4 Aurora, the author mainly used the local movie player as the test object, because the use of projection to see the movie is the ultimate goal of most users to buy the projection, the visual impact and shock brought by the big screen. Not television can match. When the user selects the local video of the USB device, the system will use its own playback software, which can be operated according to the user's personal preferences, and other third-party players can also be installed later.
The Z4 Aurora Aurora relies on the host's high color gamut and high contrast (color gamut >=120% NTSC contrast ratio of 5000:1). The effect is very good in practical projection. Whether it is viewed from the front or from the side, the effect remains the same. It is actually in the home projection. High energy performance.
In the test, the author mainly used 1080P MP4 movie as a test object, and the local play effect demonstration was based on the high configuration of the Z4 Aurora hardware. It was easily completed for local 1080P playback, and the effect was very good on the wall. When using projection, the effect of projection, brightness, etc. is also very much related to the movie. If the movie has many bright scenes and high brightness, the details can be clearly seen even when the light is on. However, when there are more dim scenes and low brightness, the effect will be greatly reduced. Therefore, users are advised to turn off the lights when using the projector. As a movie fan, I chose to use projection to enjoy the big screen and feel the shocking effects of visual impact. Extreme Z4 Aurora has a strong native playback capability. In various formats, 2K resolutions at 1080P and above are basically all you need. This is also a function that needs to be enhanced as a projection. It can achieve the same effect for the network and on-demand Android box. The format is compatible with a wide range, and local playback is strong. It is the best gift for local control + large screen control.
