takes you into the world of Samsung smart monitors Smart Monitor M7
First of all, I would like to thank the Samsung community, I am very honored to be selected for the evaluation of Samsung smart monitors. ) "The world's first "all-rounder" screen" Let's experience it.
As a 32-inch monitor, Samsung's packaging can even be described as a mini, only a mere 12cm thick, both are 32-inch monitors, and the AOC box is Samsung's 3 Double the thickness, BENQ is more than twice the thickness
It is still simple after unpacking, there are 3 large pieces of monitor body, stand and base, in addition to a remote control, a power cord, an HDMI, some manuals and other text papers quality and 3 screws and nothing else. takes you into the world of Samsung smart monitors Smart Monitor M7 First of all, I would like to thank the Samsung community, I am very honored to be selected for the evaluation of Samsung smart monitors. ) "The world's first "all-rounder" screen" Let's experience it.

Space-saving and environmentally friendly (of course, the Type-C video cable is not included, but it can be considered as a cost limit, after all, one supports 4K 60P, 100W power supply is also more than 100 Soft sister coins) Need screws to assemble a little bit of crotch Photo: Complete matte plane The random remote control details are good To control the display, when using the C2C line,An external keyboard and mouse can also be used to control the PC heat sink
is like a toy. The same webpage is displayed with such a big difference. To the pixel point
is a social animal related to pictures and videos as a sideline. The display quality of a monitor is still more important to me. Of course, different users have different needs: Accurate color is used for retouching and designing , high-brush is used to meet the stinky game, function is rich in daily office use and leisure and entertainment comparison , this Samsung monitor belongs to the latter
because I have always been interested in display devices, and there are friends around me who just happened to be The panel department of and of Hikvision has also asked for some relevant knowledge, so let’s briefly popularize several concepts that are closely related to the display:
1. color gamut
Parameters - color gamut
As long as the display is stained with wide color gamut , it means that the cost of the backlight increases, and the backlight module determines the upper limit of the display color, but after all, it is the photodiode , which is inherently insufficient for color reduction. of,If you want to improve the color display effect , the price of the display will not be too cheap.
Attached a network map, inaccurate and common different visible light spectrum maps, so the LED itself needs better technology to display more colors
And the color gamut is actually the collection of all the color ranges that the monitor can display, which usually cannot catch up with the range of the human eye—the black border range. (The color gamut picture is quoted from the first review and HDR in Call of Duty)
So in the end, we artificially delineated several common color gamut ranges, such as the most basic sRGB, as well as wide color gamut standards P3, Adobe RGB, etc. , the color ranges covered by several standards are more than one, and the price is naturally more expensive than one under the same conditions.
So do we need a wide color gamut? If you have thought about this problem in your mind, it means that you are neither from the printing industry nor the film industry, then you probably don't need a wide color gamut. For example, our cameras have supported the AdobeRGB color gamut many years ago, and our Samsung mobile phone also supports the P3 wide color gamut, but as long as we send it to the Internet, both pictures and videos will be converted to sRGB, and there is no professional use at all. It is necessary to spend more money on the color gamut. The streaming media of the entire Internet is basically sRGB. Of course, there are exceptions, fruit users. Because fruits have popularized Display P3 color gamut screens from mobile phones to notebooks and iPads, our Samsung mobile phones are naturally top-level screens that also support P3 color gamut (non-display P3, the standard represents P3 color gamut, but the gamma calculation method is different. No changes are made here. More explanations), but most of the time the content you watch is still based on sRGB display, because the Internet is not a place outside the law,As long as you watch Internet content, you can also display sRGB color honestly, so is the wide color gamut useful now? What do you think, it costs a lot of money and can't enjoy the actual service, it's unnecessary
So we evaluate a good screen The bad actually depends on the monitor's coverage of the sRGB color gamut , so we only need to see how much the Samsung screen's measured color gamut coverage in SRGB is
But when it comes to coverage, you may be worried Whether the coverage is sufficient or not will affect the display effect. On the contrary, the industry has developed to this day. Basically, the color gamut area that most monitors can actually display is larger than that of sRGB, which is close to 100%, but not many. It is precisely because it is too large that these monitors cannot display correctly. sRGB, the so-called promotion of 125% or even more than 130% of sRGB is actually the color volume, which does not have much practical significance. I'm not talking about it here. Cite a few legends about the color gamut.
The standard sRGB 100% display range is such a triangle. (For example, some monitors that claim 130% sRGB coverage (that's right, my AOC)), if you don't process it, it will cause when you want to display the most vivid green of the small triangle of sRGB, the monitor shows that it can display the brightest green. This results in oversaturated, inaccurate colors. Therefore, these wide color gamut monitors need to "restrict" the color gamut beyond sRGB. You can understand the word "restriction" as reducing a large triangle to a small triangle. This will lead to it being difficult to guarantee 100% coverage after shrinking, but for daily use,It's not too big of a problem.
The following two pictures are displays with more than 100% RGB coverage "restricted" to within 100%, and there is obvious color cast For monitors based on sRGB space, the actual coverage of 96% is good, the green point is slightly shifted, the blue point and red point are more accurate, and the accurate color can be displayed after slight correction. Just look at it, it does not belong to a high color gamut display, so the coverage does not match, it is normal A positioning is often sent when, because of the positioning accuracy, this positioning may deviate from the actual distance from me. When the monitor displays color, the coordinate difference between the actual displayed color and the target color is represented by △E, so △E is a unit of length. The (stylized) processing will improve our look and feel to a certain extent, but the display is more widely used, especially in the design category, and the color-related software has higher requirements for color accuracy. After all, no one wants to work hard to adjust the color that they want at all.
The measured △E of this Samsung monitor is 1.95, which is less than the industry-accurate value of 2. It belongs to the category of high-color-accurate monitors. The two monitors with a biased design are indeed weaker than the ones, but it can be determined that the colors are very accurate. After all, the uses are different.The price is only 1/3
Third, white :
In fact, white also belongs to the above color standard. The whites displayed are actually different. These three monitors display the same white color, which is also different.
Some people say that the color temperature of
The output image of the consistency test result is too long, and the community is not friendly to long image support, so I put it in the online disk.The picture link and the PPT link mentioned below are together. If you are interested, you can download it together. )
Compared with Samsung, Samsung's brightness is not so high. If it is in a strong backlight environment, Samsung may indeed have insufficient screen, but in general, with the blessing of Samsung's anti-emission film, the display effect is still good.
But don't look at the monitor. 100 brightness, but the production brightness of TV dramas and movies is only a mere 100nit, which means that no matter how bright the sky is or how dark the shadow is, they are compressed to the brightness of 0-100nit in the video, and the endless colors are also compressed to In the color space of BT709, this is the common SDR dynamic range. Now, if the display directly brightens the 100nit source, it may not be satisfactory, because the dark part is also brightened by the algorithm, which is not good. Panasonic is BT2100) deeper dark and brighter light, Samsung's M7 monitor supports HDR10, which can perfectly display a wider dynamic range, the picture effect is still good
There are many HDR sources on YouTube , you can use the device that supports HDR and the device that does not support to play it separately. You are not afraid of not knowing the goods, but you are afraid of comparing the goods. Put the two sides together to see the difference in the video. (If you can't find a screen that supports HDR around, our Samsung flagship mobile phone has long been a device that supports HDR10/10+, and you can compare it with the unsupported devices)
Here is an official original version of HDR ACTV by the way. ppt,Pure English, you can download it if you are interested, the PPT is about 300M, and the screenshot of the previous page is attached. The screenshot of the consistency test above is also in the network disk. If you are interested, you can download it on demand.
The above is the concept and measured data of display parameters :
As a smart display, Samsung is too capable. In this regard, the other two displays are slag and slag left,
① Traditional display functions:
Smart Monitor M7 has
C also support USB expansion. When connecting C After the port, the 3 USB ports on the back of the monitor can be connected to the mouse and keyboard, which solves the problem that some computers have insufficient USB ports or are too far away from the host to be inconvenient to plug in cables. Under the premise of high requirements, the overall satisfaction is
. As the standard configuration of the current mid-range and above monitors, Samsung must have it. The all-dark environment is not dazzling, the all-bright environment is clear and convenient, and the Shenma eye protection low blue light game mode is messy.However, as one of the world's leading panel manufacturers, Samsung's VA panel has been adjusted to a level close to IPS, with a viewing angle of 178 degrees, and there is basically no smear of VA. It is very friendly to our own Samsung mobile phone users. The wirelessDEX function is unique. The mobile phone that is often used in mobile office can be directly connected to the wireless dex after going home, and it can be seamlessly switched to the computer office experience. The TPA VIEW function can easily synchronize pictures and videos to the monitor. Is the Airplay2 function a hidden function, or a function that I found after consulting the product manual of the M7 sold in the HK region. It is necessary to flash the Hong Kong version of the system and switch to and in the Hong Kong region (not recommended, it will lose the warranty and cause the system to fail.) Stable, the internal area switching function is invalid, but you can install YouTube, Netflix and other mainland software that cannot be used, bring your own tomato), you can activate the AIRPLAY2 function supported by the display (perhaps this function may be blocked in the future?)
Wireless DEX :
DEX, as the cross-platform interactive experience function promoted by Samsung in recent years, allows you to seamlessly switch between mobile office and home office with just one mobile phone, and you can also have a similar experience with a computer when working from home. And this monitor directly supports the wireless DEX function, eliminating the trouble of wiring, and the monitor can also be directly inserted into the keyboard and mouse, which is more convenient.
· Smart TV function:
Samsung has equipped this monitor with a remote control for the first time, and it is the same remote control as Samsung TV. The function is simple and convenient. It also supports bixby. It is basically the same as the Samsung TV at home.The TV is placed in the office and is fine to peek at iQIYI. When the boss comes, it is perfect to switch directly to the secondary screen of the computer. The screen mirroring function through the DLAN protocol is also very convenient. The video application in the mobile APP can be directly displayed on the screen, and there is no audio delay in the audio and video synchronization. Its unique function, there is a high-performance PC at home, as long as this monitor has a network, you can use the home computer to complete the work remotely, except for some sacrifice of some display effects and some perceptible delay, it is really a perfect streaming media transmission The essence of the solution is similar to some cloud games that have already begun to exist. The computing is placed in the cloud (one computer in a different place), and the local is just a display and an operation controller.
However, yes, there must be. We are in a large public network environment as a whole. Basically, there is no independent fixed external network IP for individuals. Everyone has a dynamic IP. It is a big problem to access the internal network from the external network. The bandwidth requirements are also huge, and the degradation of image quality and delay is also a huge experience problem, just because of this! So this time I will not do the experience of this function, just attach the function entry and the corresponding pictures. This function is definitely a common function in the future IPV6 environment (face slaps are not accepted, it is still early) Multi-device linkage will be very convenient (but Samsung dad's smart home device is not cheap, this Versailles function can do what it can,Local tyrants are free)
Wifi supports AC 5G, temporarily does not support wifi6 AX Bluetooth is BT4.2 Overall, it is quite enough for a monitor It belongs to the middle and upper level, with obvious advantages and basically controllable disadvantages. But with the tizen system and a series of smart functions, the current price is simply for nothing!
So you have to ask me if this monitor is worth it, asks, buy it!
(The color gamut picture is quoted from the first review and HDR in Call of Duty)
So in the end, we artificially delineated several common color gamut ranges, such as the most basic sRGB, as well as wide color gamut standards P3, Adobe RGB, etc. , the color ranges covered by several standards are more than one, and the price is naturally more expensive than one under the same conditions.

Use, what do you think, spending more money and not enjoying the actual service, there is no need for
. So when we evaluate the quality of a screen, we still need to look at the monitor's coverage of the sRGB color gamut, , so we only We need to take a look at the measured color gamut coverage of Samsung's screen in SRGB this time. On the contrary, the industry has developed to this day. Basically, the color gamut area that most monitors can actually display is larger than that of sRGB, which is close to 100%, but not many.

This will cause it to be difficult to guarantee 100% coverage after shrinking, but for daily use, it is not a big problem. Inside, there is obvious color cast
and the picture below shows Smart Monitor M7 measured color space , this is a monitor based on sRGB space, the actual coverage of 96% is good, the green point is slightly offset, the blue point and red point are more accurate , it is very good to display accurate colors after slight correction, NTSC/P3/ARGB these three color spaces are good, it is not a high color gamut display, so the coverage does not match. The color accuracy, as the name suggests, is the color accuracy represented by △E. For example, we often send a positioning when we tell others where we are. Because of positioning accuracy, this positioning may deviate from the actual distance from me.

These two monitors that are biased towards design are indeed weaker, but it can be determined that the color is very accurate. After all, the usage is different, and the price is only 1/3
Third, white :
In fact, white also belongs to the above color standard range The most easily overlooked display color cast is actually white. Generally, it is the kind that does not hurt without contrast. The white color displayed by each display is actually different. These three monitors display the same white color, which is also different.
Some people say that the color temperature of

together. Fourth, brightness :
The brightness of the three monitors are: Samsung 250nit (measured 257nit), AOC 600nit (measured 615nit), benq450nit (measured 449nit)
In comparison, Samsung's brightness is not so high. If it is in a strong backlight environment, Samsung may indeed have insufficient screen.

Sixth, summary:
Samsung's display is still relatively capable, all parameters at this price belong to the upper-middle level, the advantages are obvious, and the disadvantages are basically controllable. But with the tizen system and a series of smart functions, the current price is simply for nothing!
So you have to ask me if this monitor is worth it, asks, buy it!
