The height of the H1 meter is as high as 900 Ansi Lumens, which is a 55% increase, and has a good viewing effect even during daytime viewing. Through our tests, we found that projecting a closer picture, the brightness of the picture would be a bit dazzling. In any case, I was deeply stunned. I suggest that you choose to project larger and farther pictures when projecting. This will not cause the eyes to hurt.
I use the meter-less screen TV H1 and the meter Z4 Aurora screen to make a comparison, in order to give everyone the most realistic visual experience: the following comparison chart without instructions is: left pole meter screenless TV H1, right pole meter Z4 aurora .
Color performance: 
Judging from the above color performance, the picture quality of the H1 screenless TV is more realistic and natural, and the white of the Z4 Aurora is biased towards blue.
Grayscale test:
Compared with the Z4 Aurora Polari, the display performance of the H1 Grayscale TV without screen TV is stronger, which means that the details of the H1 without screen TV are more detailed, especially the details in the dark part. 
4K HD contrast chart display: 
From the contrast picture of the polar meter H1 and the polar meter Z4 in the above figure, the screen performance performance of the screenless TV H1 is excellent, the color reproduction is real and natural, and the Z4 Aurora polar image is dark. The Hami No Screen TV H1 is worthy of a new height in the industry with a brightness of 900 ANSI lumens and a resolution of 1080P.
