Exterior:
Appearance, the pole meter Z3S continues the previous generation product design, the fuselage surface is made of tempered glass, its size is 232x132.8x40mm, thickness is about 31mm, body weight is 0.8kg, easy to carry.
In front view, there is not much change, the lens is still hidden under the magnetic shield, both beautiful and dust-proof. 
The top view is that the center of the white acrylic panel is the metre brand LOGO and the carcass brand. The right side of the screen is the focusing knob and the main function virtual buttons. 
Rear panel, interfaces are all concentrated in the rear panel, from left to right are TF card slot, power interface, two USB2.0 interfaces, one USB3.0 interface, two HDMI input interfaces, hardware switches, audio fiber interfaces, AV Interface, wired network port and headphone port. Compared with the Z3M, a USB 3.0 interface and an HDMI input interface are added, one VGA interface and an external antenna are missing. 
system interface:
The boot enters the homepage of the Z3S system. As shown in the figure, the Z3S system interface consists of recommendations, video, local, settings, games, and applications. Swipe right to display more content. It is more intuitive and more user-friendly. With the included remote control, you can freely select the appropriate page and use the application. 
Brightness test:
The measured, peak meter Z3S projector peak brightness of up to 447 lumens, the maximum brightness of 413 lumens, the measured ANSI brightness of 333 lumens. The peak brightness, especially in the brightest mode, the highest brightness that a single point can reach, generally occurs at the center point; the maximum brightness refers to the brightness that can be reached on average in the brightest mode. The reference value of this value is even higher. high. 
Color test:
The color demonstration effect is also one of the weight standards for considering the performance of the projector. The accurate and vivid color effect is a powerful guarantee for the positioning of the miniature projector in the home area. Let's take a look at the color performance of the Z3S. 
Through the actual test, because the pole Z3S uses LED light source, a wide color gamut, from the effect of real shot to see the color effect is still good, G, B, Y three pure color effects are more natural, red slightly pink.
HD movie effects:
Finally, let's take a look at the performance of the Extreme Z3S in practical applications. The most important purpose of home projectors is to play videos, and HD movies are undoubtedly very testable for product details and color performance. In the following tests, we all selected high-definition pictures to take shots of fixed scenes. Through detailed comparisons, we demonstrated the effects of Z3S. 
Extreme Z3S has better performance in the overall demonstration performance. The color display is bright and the dark details of the screen are well preserved. It is very suitable for personal home theater enthusiasts to build a private theater. Its high brightness performance also reduces the environment. The impact of projection screen
to sum up:
Extreme Z3S has a qualitative improvement over its predecessor in hardware level and firmware optimization. The use of dual-band Wi-Fi signals is beneficial to high-speed and stable viewing of high-definition video in the LAN, and the transmission of data will be smoother. This is undoubtedly a major positive news for the majority of HD enthusiasts, but the premise is that preparation is needed. A dual-band wireless router is supported.
