0.21:1 Throw RatioUItra short throw ratio,100"image just need 14cm away from the screen
High Quality SpeakerChanghong is a 61 years old traditional TV manufacturer, our mainboard solution is same as high end LED/LCD CHIQ TV. It is completely different from traditional projector manufacturer.
60Hz refresh rate, Support 2.4G / 5G wifiScreen refresh rate determines the speed of screen response, the higher the refresh rate, the better the image stability, changhong TV uses
60hz ultra-high refresh rate and combines with ultra-hd resolution and motion compensation to present smooth TV images for you, rejectting the phenomenons, like standstill, dragging tail and so on.
Intelligent processor, 3GB+64GB Big MemoryCPU: Cortex 73/Dual Core Cortex 53/Dual Core (1.7GHz)
GPU: Mali-G51/Duo Core
The projector uses the main board of the TV set, is better than other projector.
Dual Core processor with 3G RAM+64G ROM, running smoothly without jamming.
Multiple InterfacesHDMI 2.0 specification can support maximum 18Gbps transmission bandwidth. This version conforms to the current market and greatly enhances the transmission bandwidth and speed. HDMI2.0 improvesframe rate up to 50/60Hz, supports 4k signal transmission, makes image more clear and sound more stereo, keeps strong compatibility, and enrichse users' visual-audio experience.
Why Choose the B5U?Traditional TV : Screen too small / It's bad for eyes to watch too long
Traditional Projector :It needs to be long enough to project a large enough picture. If the room is too small, you can't enjoy the big screen
B5U : You can choose any size screen that you want. no need care the room size. no limit.

Q & AQ1: B5U is not as bright as TV
A1: LED TV uses same light source of LED light: Light Emitting Diode, if we stare at TV screen, just like we stare at LED glare, our eyes get exhausted easily, which causes near sight. Staring at projection screen is like staring at natural views, they are reflecting light.
Q2: What is the difference between LED and laser light source?
A2: LED Light Source: wavelength 415-450nm VS Changhong Laser Projector: wavelength>455nm. LED's polarized light accelerates visual Fatigue, reflecting laser light brings natural color.
Q3: What is MEMC?
A3: Motion Estimation/Motion Compensation, an algorithmic technique used to predict a frame in a video, given the previous and/or future frames by accounting for motion of the camera and/or objects in the video.
Q4: Why MEMC is a must for a giant screen above 65"?
A4: It is hard for human eyes to tell the difference W/O MEMC when the screen is below 65” and playing fast moving images. When it comes to above 65”, like for 100”, MEMC is able to make animation more fluid, to compensate for display motion blur, and for fake slow motion effects.
Q5: What is 115% BT.709 Color Gamut?
A5: If we take BT.709 as a triangle, square meter=1. Then B5U’s square meter=1.15 BT.709 represent total color numbers in the triangle.
Q6: Why we need an ALR screen for B5U.
A6: Black grid screen optic gain is 0.6, it loses 40% brightness which escapes to left, right and bottom directions, but it rejected ambient lights, without ambient light influence, the image’s color, color temperature, contrast…get better.
White wall(PVC screen) optic gain is 1.0 Fresnel screen optic gain is 1.3, which means it gathers 30% more lights to one direction, in the meaning time, the color, color temperature, contrast are much better.
Q7: Why HDR is important to a movie?
A7: High Dynamic Range, used in imaging and photography to reproduce a greater dynamic range of luminosity. Simply speaking, without HDR, you can’t see details in the dark, and you find some white smog covers the bright part.
Q8: Why we need better configuration in a projector.
A8: Like a computer, projector is required to calculate when it is working, 3+64G configuration projector’s working speed is far better than 1.5+8G, 2+32G…We can’t tolerate lag in games, surely we can’t tolerate lag in movie.
CPU: Cortex 73 /Duo-core+ Cortex 53/Duo-core(1.7GHz)
GPU: Mail-G51/Duo-core
RAM+ROM: 3+64G
Q9: What is TR 0.21: 1
A9: TR=Throw Ratio, is the ratio of the distance from the lens to the screen (throw) to the screen width. For 16:9 ratio screen 100” width 2214mm, B5U TR 0.21. Then the distance from lens to screen=2214mmx0.21=464mm. The distance from lens to projector back=272mm. Then the distance from projector back to screen=464mm-272mm=19.2mm.
Q10: Why heat-dissipating is important?
A10: Too much heat radiation will reduce laser light source lifetime, will decrease brightness, will make people uncomfortable. CHIQ guarantee: anytime you touch B5U, it is cool.
Q11: Energy Saving Optic Engine?
A11: 31lm/W high efficiency optic Engine VS Industry Average 18lm/W
B5U 260W VS VAVA 360W
B5U: 95W laser light source, which supports 95Wx31lm/W=2850lm. But Pico 0.47 chip’s can’t tolerate the temperature which 2000lm and above brings.
Q12: Why Changhong Develop Fresnel Screen Optic Gain >1.3?
A12: The effect is achieved by positioning the projector and screen in such a way that the projector's light is bounced towards the audience, while the other light in the room is reflected back in some other direction. So that B5U+S100FX can reach 350nit@100”, to ompete with LED/LCD TV. With advanced technologies, CHIQ S100FX reaches optic gain >1.3 which means brightness, contrast, color performance reach a new level
