As people’s demand for large-screen experiences continues to increase, large-sized TV products are becoming more and more popular. At the same time, projection TVs that can more easily acquire a large-screen experience have gradually become a new choice for some consumers. And like smart TVs, smart projections that incorporate TV boxes and projection capabilities are also gaining attention. Hami no screen TV H1 is such a similar smart projection, its biggest feature is the brightness of 900 ANSI lumens and built-in Harman Kardon sound system, priced at 4,999 yuan, known not pull curtains can also get good As a result, instead of TV, then let's take a look at its actual experience.
First of all, let's code the hardware parameters of the screenless TV H1:
Processor: Mstar 6A928 (Cortex-A17 architecture, 4-core 1.75GHz)
GPU: Mail-T760 MP4
Memory: 3GB DDR3
Body Storage: 16GB eMMC High Speed ​​Flash
Standard output resolution: 1080P (19201080)
Operating System: Android 5.1.1 System
Others: 3750 lumens (900 ANSI lumens)
Appearance atmospheric interface 
As a home projector, Hami no screen TV H1 in the appearance of the use of a rounded cube design, compared to the previous generation product Z4 flat style, this gives a feeling of steady atmosphere, it looks like a lot of belly.
At the same time, the combination of gray brushed metal and black plastic panels is used as a whole. At first glance, it also looks more refined. The whole machine also has a large number of cooling holes. Workmanship is also good, seams and edge trims are handled more delicate, no burr, good texture. 
Concise interface rich in resources 
Audiovisual shock but still have to pull curtains
In the actual viewing experience. I conducted related tests by online on-demand and local 4K source playback. 
The first is the online video section. The selected film source is the “Shan Hai Jing†featured in the movie and TV column. In actual experience, the screen effect is still excellent, the sound is quite shocking, and the loading is smooth and the playback experience is good. 
In the local source test, I chose the 4K sample “Beauty and Roast Duckâ€. Although the Hami H1 only has a 1080P resolution, it can easily decode the 4K source, and it is also very smooth during playback. It is also worth noting that it is not fast when fast forward. 
We also experienced the darkness and the blinds separately. It can be seen that the effect of the dark picture is still very shocking, after all, the picture size is still very large, while the quality and sound effects are also good. However, in the end of the day, it still feels like we need to work hard and the effect is general.
In terms of heat dissipation, the No-Screen TV H1 performed well and did not overheat after two hours of use in the test. A large number of fan holes and dual fan designs do have a good effect.
summary:
After a period of trials, the deepest impression on the H1 screenless TV is that the picture quality is excellent and the sound is shocking. Compared with the TV, it can be easily moved to make its application scenario have a lot of imagination. Second, online resources are rich, interaction is smooth, and the quality of related content is also good.
Of course, if you want to get good viewing results in daily situations, you need to turn off the lights or pull the curtains. However, this issue is not limited to only meters. Almost all current products in the market have stagnated on this issue. It has been considered that the K1 H1 can evolve from the previous Z4 Aurora 580 ANSI lumens to 900 ANSI lumens. However, the revolution has not been successful. Comrades need to work hard. At present, it is still difficult to replace television. At the same time, the price of 4,999 yuan is less advantageous than TV, and you can already buy a 55-inch 4K smart TV that works well.
In general, Mimi calls its smart TV a screenless TV, and the target users are still more renters and young white-collar workers. Although it is still inferior to the picture quality of TV in the daytime environment, the display effect in dark conditions is still satisfactory. At the same time, it is better than being portable and practical. Just give it a wall and it will take up less space. Still very convenient. For renting, space is limited and there is a demand for large screens, it can be considered for people who are less sensitive to price.
The projection screen of the meterless screen TV H1 is on the front side of the camera with a resolution of 1080P (1920×1080), a brightness of 3750 lumens (900 ANSI lumens), a contrast ratio of 10,000:1, and a light source of LED, which is used by Texas Instruments. DLP technology, compatible with 4K decoding, support 3D, can be trapezoidal correction up and down.
As a major feature of Nomi screenless TV, is the addition of Harman Kardon Audio, this H1 is no exception. Equipped with a 45mm dual speaker unit, located on the bottom of the fuselage, increased by 50% compared to the Z4 aurora. At the same time, due to its increase in size, the size of the sound cavity has reached 6 times that of the Z4 aurora.
The lens itself does not provide focus knob, but through the operation of the bottom of the fn button after the power button to adjust.
As a smart projector, the HMI no screen TV H1 is equipped with a rich interface, in the lower back is a USB 2.0 and a USB 3.0 interface, 2 HDMI 2.0 interface, 1 SPDIF interface, 1 HDMI ARC interface , 1 headphone jack and Ethernet port. In addition to the traditional projection function of the screenless TV H1, these interfaces also help to improve its scalability, such as external U disk and mobile hard disk for local playback.
There is a physical power switch on the body of the screenless TV H1, as well as a volume control button that can be swiped and a common fast-forward, rewind, and favorite button. It is very easy to get started. At the same time, the key reaction is also very sensitive, and the feedback is good.
The UI of the main interface adopts the Metro style interface that is commonly used in mainstream boxes on the market. The overall design is very concise. Film and television, music, games, and applications are the top ten sections, which also cover other basic functions for easy search and selection.
At the same time, the remote control is still relatively handy and responsive, the experience is very smooth, and the appearance is also in tune with the body. However, if the buttons can be slightly larger and the layout is not so tight, it should be more convenient to operate.
As a smart projection, resources are surely indispensable, and the cooperation of the polar meters in content is mainly mango TV, and its video resources are still very rich.
Since it is in cooperation with Mango TV, the exclusive variety show is naturally a major feature, and its quantity and quality can be guaranteed.
In terms of games and applications, it is similar to other boxes and TVs that use the Android system. Currently, they are simple casual games and everyday applications.
Observe the effect in the dark
Watch the effect during the day
At the same time, I also simulated the viewing effect in the non-drawing curtain environment. It can be seen that even if the brightness of the Himi H1 is nominally 900 ANSI lumens, the overall effect will still be seen if the light is indoors during the daytime. Hit some discounts.
