In 2020, the conference tablet market is very active. Due to the emergence of the epidemic, the demand for remote meetings has surged. Traditional projectors and LCD TVs cannot effectively coordinate the two places. Conference flat panel products have become the first choice for meeting room upgrades. At the same time, innovative applications such as the whiteboard and projection screen of the conference tablet itself greatly increase the flexibility of the conference. Therefore, more and more people are paying attention to conference tablet products. But as a new category, many buyers still don't understand how to choose such products. To this end, we deliberately launched a Hengping review of five mainstream conference tablet products.
screen He Shengsheng Five conference tablets Hengping: Comprehensive display
This article focuses on the display capabilities of conference tablets. This point is often overlooked. In fact, high-quality color performance greatly improves the conference effect. Today we will test the display capabilities of these five products.
The five conference tablets we selected are MAXHUB V5 Technology Edition, Huawei Enterprise Smart Screen IdeaHub Pro 65 (Huawei Office is its "nickname"), NEC NETRIX NS651R, Haoli 75 M4 and Honghe ICB-V65P. They are all mainstream products on the market, and they are representative.
To investigate the screen, we must first start with the appearance design. The MAXHUB V5 technology version and Huawei IdeaHub Pro65 all use a fully-fit design. The full lamination technology eliminates the air between the screens, which helps to reduce the reflection between the display panel and the glass, which can make the screen look more transparent and enhance the display effect of the screen. However, the cost of a fully-fitted design is higher. Therefore, the MAXHUB V5 technology version and Huawei IdeaHub Pro65 are priced at 40,000 yuan, while NEC NETRIX NS651R is priced at only 20,000 yuan, and Haoli 75 M4 (same size price For 24,000 yuan).

At the same time, MAXHUB V5 technology version and Huawei IdeaHub Pro65 also adopt a narrow frame design, so that the screen is not only more beautiful, but also effectively reduces the volume of the product. It is also 65 inches, and the narrow bezel design makes the product look more lightweight.
We also used the professional color comparator Spyder X to test the color gamut and color reproduction ability of the screen. This instrument can truly and effectively test the screen quality of the conference panel. The following are the real test results of five conference tablet products.

color reproduction ability comparison of five products
In terms of color reproduction ability, the average value of Delta E should be as small as possible. Generally speaking, the value of this value is 1.5 or less for liquid crystal displays dedicated to graphics. According to the actual color measurement results of the five products, the smallest value is the MAXHUB V5 technology version 1.31. The Haoli 75 M4 and Huawei IdeaHub Pro 65 are at a slightly higher level than 3.0 and perform very well. It is necessary to know that the average value of Delta E of many gaming monitors is also above and below this level. Considering the price element, the color reproduction of the Haoli 75 M4 conference panel is the most "cost-effective". The MAXHUB V5 technology version has a professional color standard, which can be competent for more rigorous professional drawing and color matching scenes.
The color gamut effect comparison of five products
For office, the performance of sRGB color gamut is the most noteworthy, because the daily office materials and displayed videos are basically produced and presented under the sRGB standard. Through the color gamut comparison, we can find that the sRGB color gamut performance of the five products is good, basically at a level of 98% to 100%. In actual use, the gap is not obvious to the naked eye. Therefore, the color gamut of the five products can be used for conference display, which can meet the demand. Among them, the sRGB color gamut of Huawei IdeaHub Pro 65 performed best, while Honghe ICB-V65P performed slightly worse. The 99% sRGB color gamut of MAXHUB V5 technology version and other products is excellent.
The AdobeRGB color gamut is more suitable for the design field. The DCI-P3 color gamut is mainly used in the video production and film production industries. Under these two color gamut standards, Huawei IdeaHub Pro 65 and NEC NETRIX NS651R perform better, but the gap is MAXHUB V5 technology version and Haoli 75 M4 are not big.
Next, let's take a look at the brightness contrast of the five products. For this we use its brightness value of 50% for comparison. Because in general standard display mode, the brightness value is basically 50%. The brightest mode picture may show whitening and lack of picture detail.
Through data comparison, it can be seen that the brightness of the Haoli 75 M4 conference panel is the best, and the 50% level has reached 332.6 nits. The MAXHUB V5 technology version also has the level of 300 nits or more. For conference tablets, brightness performance is very important because they often have meetings during the day. At the same time, the purchase cost of brighter LCD panels is also higher. NEC NETRIX NS651R has a brightness of 280.4 nits, which is relatively high-quality. The brightness of the other two products is relatively different.
Just check the data, maybe you don't have a perceptual understanding of the color performance of the five conference tablets. We deliberately carried out a screen shot comparison. Compare the display effect of the same picture on the five products with the original picture, so that everyone has a clear understanding of the color performance of the five products.

real shot diagram verifies the results of the data test. First of all, let's look at the color gamut performance. The color problems of the five products are not big, and there is no obvious lack of color gamut. In terms of color reproduction capabilities, the MAXHUB V5 technology version, Haoli 75 M4 and Huawei IdeaHub Pro65 perform better and are closer to the original color effect. We can tell this from the color of the barbecue in the middle of the first screen shot. The three products mentioned above basically restore the true color of flesh.
In terms of brightness expression, it can be seen from the contrast image of the second screen that the brightness of the person's skin color is sufficient, the brightness of the Haoli 75 M4 conference panel is very sufficient, the person's skin color is very shiny, and the contrast of light and dark on the screen is very strong. The brightness performance of MAXHUB V5 technology version and NEC NETRIX NS651R is also very powerful. Relatively speaking, the screen brightness of Huawei IdeaHub Pro 65 is low. Comprehensive comments on
:
Appearance design and screen measurement results prove that the fully-fitted design can bring a thinner and lighter design, while also conducive to narrowing the frame and highlighting the integrity of the screen. In addition, full bonding is also conducive to the optimization of capacitive touch, which we will mention later in the application test. The full-fit design of MAXHUB V5 technology version and Huawei IdeaHub Pro 65 is more dominant in appearance design.
In terms of screen display, we can look at it separately. The MAXHUB V5 technology version has the most comprehensive performance, good color gamut, and the highest restoration accuracy. At the same time, the brightness data is also at the upper middle level. Especially the reduction ability is commendable, almost comparable to professional graphics monitors.
The color gamut and restoration capability of Huawei IdeaHub Pro 65 are good, but the brightness data is slightly worse. The screen display capability of Haoli 75 M4 conference tablet is also high-quality, with excellent color gamut and color reproduction capabilities, and its brightness performance is the best of the five products. Huawei IdeaHub Pro 65 is not a traditional conference tablet. It is an intelligent collaboration terminal that seamlessly integrates Huawei cloud services with Huawei's self-developed hardware, algorithms, and Huawei terminal application ecology. Today we are evaluating, mainly its built-in cloud native meeting capabilities. The screen display capability is just the basis. The color gamut of
NEC NETRIX NS651R is excellent, and the brightness performance is also at the upper-middle level. But its color reproduction ability is slightly worse, of course this is also a comparison. Compared to the average Delta E level of many LCD TVs above 7.0, NEC NETRIX NS651R 4.0 can also meet the basic meeting needs. After all, the price of this product is the most favorable.
Honghe ICB-V65P is a more conventional product in terms of display capabilities. Its color gamut, brightness, and color reproduction capabilities are all qualified. It can be said that there is no problem for conference display, but there is still room for improvement compared to similar products.
