Commercial projectors can also be so high-quality Ricoh PJ RU220 high-brightness commercial projecto

With the continuous pursuit of high-definition display image quality, projection products are also constantly developing and improving in terms of resolution, performance, etc. Not only are projectors required to have high brightness, but also high resolution and rich functions, which is also an engineering projector market. Brings new vitality.

Today, we got an all-round 4K laser engineering projector, the inASK V series 3LCD laser projector VLK600, let us experience it together.

First, let's first understand the basic information of the VLK600. The biggest highlight of this machine is the 4K resolution (3840 2160), which makes the picture quality more delicate. It adopts a combination of 3LCD+ laser light source display technology. 3LCD technology can restore bright colors more realistically, and the service life of the laser light source reaches 20,000 hours. The brightness of this product was tested to be 6000 lumens. The comprehensive indicators of this machine are very suitable for use in various large-screen display scenarios such as exhibitions and conference halls. It has lens displacement, multiple trapezoid corrections, multiple image modes, and rich interfaces. and other functions. Let's explore the experience one by one.

1. Appearance experience

1. Model appearance

The moment I took it back and unpacked it, it was absorbed by its high-end. It is simple white, and the user-friendly button design also has a technological digital feel.

Compared with models of the same level, it is lighter in weight, indicating that it has better heat dissipation and is easier to transport and install. You can also easily enter a narrower space and expand more application scenarios.

2. Control panel

Its control panel is located on the top of the fuselage, so we can very conveniently perform common operations such as power switches, menu operations, trapezoidal correction, lens displacement, and sound and picture input. It is very practical.

The lens displacement knob can be easily controlled and can easily adjust the screen installation position. The entire adjustment process is very convenient and the operation is simple and quick.

3. Interface aspects

There is an interface area on the back of the projector's body, which is very rich in interfaces: two HDMI interfaces, audio interface, two USB interfaces, network interface, RS232 interface, etc., allowing simultaneous access of multiple signals for presentation, and the silky connection is enough to cope with the needs of professional engineering.

It is worth noting that this machine also has an optional HDBaseT interface to meet long-distance engineering transmission.

Let us experience performance and image quality

2. Performance experience

1. Image quality and experience in multiple image modes

Picture texture is a major advantage of this engineering projector and its essential basic performance. Here are some test pictures and videos to experience its projection effect immersively.

Based on its powerful image scene analysis capabilities, the inASK VLK600 has a dynamic contrast ratio of up to

5000000:1, you should know that in the same type of projector, this dynamic contrast ratio reaches an extremely high value. The higher it is, the more you can ensure that every detail of the picture, including the dark part of the picture, can fully express its level, bringing rich and delicate visual enjoyment.

I may not be intuitive enough to say this. The following picture shows: You can see that some small stripes are very clearly different, and the differences can be seen in similar colors. It is no exaggeration to say that they are much clearer than looking at the original picture on a computer.

Secondly, the color brightness of 6000 lumens and 3LCD projection technology can make color reproduction more realistic and the picture quality softer.

Here we can look at the restoration of the character's skin color: personally, it is very soft and natural, not stiff, the visual effect is great, it feels particularly like the feeling of a person standing in front of it, and the restoration is extremely high.

The key point is that the requirements for high-definition image quality are getting higher and higher, especially for engineering projectors. Its 4K resolution can be said to be the image quality of the first echelon of high-definition projectors. It can present ultra-high-definition video images, even on large screens. When projecting, clear and vivid details can still be maintained without blurring problems, giving us a vibrant visual experience.

In my test picture, you can see that the rugged texture of the rock and the details of the animal hair are all displayed in detail. The transparent effect appears on the screen, which is pleasing to the eye.

Let's take a closer look at its image setting function. First enter the main menu, you can see very professional option settings, including screen settings, as well as a series of functions such as installation and debugging.

In the image settings, the adjustable options are really rich, and we can make rich matching and fine-tuning. Not only are the image modes preset, but the color temperature, color space, etc. are also preset values. You can directly switch and select them, and then use brightness, color, chroma, sharpness and other parameters to achieve the desired final effect.

I usually turn down the brightness when turning on the light to keep it clear and bright, but in fact, even if the light is turned on, it will not affect the projected picture at all. After all, in exhibitions with more complex lighting conditions, this projector can still maintain reliable display effects in environments such as exhibitions.

I have to say that the image quality of the inASK VLK600 engineering projector is quite good. Whether it is steep mountains and rivers, lush forests, or artistic exhibition halls, it can be clearly presented. At the same time, the picture texture is delicate and exquisite, bringing us A refreshing visual experience.

It is worth mentioning that the depth of field and detail presentation of the projection quality of the inASK VLK600 engineering projector have been further enhanced, presenting a clearer and more realistic image effect.

Actual film and television tests also verified the power of this laser projector and brought a shocking experience like a live scene.

2. Test experience of trapezoidal correction and multi-point correction

It has built-in multiple screen adjustment tools such as horizontal trapezoidal correction, trapezoidal distortion adjustment, hexagonal correction, and multi-point correction adjustment. It can easily create the C-position focus of the venue and ensure that it can be achieved on all kinds of irregular projection surfaces. Super positive imaging effect.

The most intuitive thing is that I place the projector on the side and tilt it for projection. After multi-point correction, I can still harvest a complete and front picture. I don't have to find a suitable position for the projector to flatten the picture. Indispensable features in the engineering field.

3. Lens displacement testing experience

The lens design of this product includes lens shift and optical zoom. It can pan the picture without loss. When the projector is too high, you don't have to worry that it will not be able to project into the ideal position. Just move the lens downward to the position you want. In addition, it is also more friendly to achieve splicing and fusion functions. There is a range of lens displacement here, which is from 0% to +66% vertically and +29% horizontally. When operating lens displacement, the screen will display the displacement value, which can be accurately debugged and is very intuitive; it can also be operated like I do below., it is more convenient to directly rotate the button above the fuselage to adjust.

Zoom and focus are also adjusted manually. There is a black rotating ring next to the lens, which can be adjusted by dialing. It is very convenient and agile to operate, and the experience is very good.
