Brightness is sufficient to highlight
The human eye is dynamic for brightness, and most important is to match the ambient light. With the progress of the projector technology, the time to watch the movie first, the era of pulling the shuttle has passed. So let's take a look at the brightness effect of this projector. And the performance of this projector 3300 lumen believes that everyone is paying attention.
Full black environment picture screen
Open the room in the room
After opening the lights, the color has no effect, and the overall view is called excellent. Vivitek H658F projector has 3300 lumens brightness, and actual tests have also found that the brightness of the picture is better than the general machine in the case of opening up indoor lamps.
The test of this night scene we can see that Vivitek's projection is also in place. If the brightness and contrast are insufficient, the details of the body are difficult to see, and even the outline can not see. The H658F benefits from 3300 lumens and 15000: 1 contrast, showing the overall dark portion detail.
In terms of brightness, we also tested E580 using TES136 illuminance, peak brightness of 3142LM, about 95.21% of the official nominal brightness of 3300LM. In general, if the peak brightness can be close to 95% of the nominal value or even exceeding the marking value is optimal. Vivitek H658F can be said to be completely relieved in terms of brightness.
On the importance of color reduction and the visual enjoyment
Color is the most critical factor in the performance of the projector, and the user needs a true restore color, the clear and delicate picture, how is the Vivitek H658F? We use the OPPO UDP-203 as a signal source to perform a series of screen photos.
Vivitek H658F has a 6-segment color wheel technology of an upgraded version, optimizes the color ratio of color wheel, which greatly enhances color saturation, making each pixel point of 256 color changes, but it not only improves color accuracy Sex, simultaneous mixing color is more bright and true.
From the screen view, we can see that this projector adds color saturation through the intensiveness of the intermediate tone, making the picture color more realistic and more active. The items in the above picture, the color is bright but not too full, the transition is natural, distinguishable, no color overflow is found.
The real scene in the figure above the sky, the color of the blue sky and the color of the sea, the clouds of the cloud, and the yellow color of the wheat is very good. On the control of the color, Vivitek (Li Xun) H658F is satisfied.
Compared to TV, the projector picture is closer to the taste of the cinema, which may be one of many people have a unique reason for the projection machine. In addition, the projector is different from the liquid crystal TV, the latter is subject to the liquid crystal molecular deflection speed, which is not ideal when expressing dynamic scenes, such as high-speed sports football easy to produce a trailing. Vivitek's dynamic performance of H658F is excellent, football trajectory is very clear, which is hard to see on the LCD TV.
As the saying goes, the details are true. We can see from the screen, the picture level is clear, the transition is very nature. In the picture, the performance of the details is also very in place, whether it is the white clouds on the top of Fuji, or the fireworks burning in the firewood, the library is displayed, which gives people a true and natural feeling.
Objective testing truth from facts
First we have conducted color step testing, overall performance in expectations, except for the top 4, others can clearly distinguish.
In the movie preset image mode, the performance of the white field and the black field is also very good, and no additional adjustment can be made.
For a household projector, noise is a very critical index. After all, no one wants to watch in a noisy environment, but also affects the family's rest. In the living room of 32 decibels in ambient noise, the noise value measured at 1 meter from the machine is 37.7 decibels, almost noise generated by the machine, has no effect on the rest of the family.
Power consumption is also an important parameter of the home projector. It is measured by measurement. It will be about 265 watts after opening the energy-saving mode, and the overall energy can save 16%. While energy saving, we can see that the brightness of the picture is basically no change.
