The tangled road of monitor purchase

The middle-aged uncle received a 27-inch 4K monitor (ViewSonic's vx2780-4k-HD3) on his birthday last year. It has been used as an external monitor of my laptop for nearly a year. There is one thing to say, the display itself is still good, with a resolution of 3840×2160 (4K), 10bit, 116% sRGB wide color gamut, 178° wide viewing angle, 4ms response time, three-sided micro bezel, support for rotating up and down, DC filter blue light There is no flicker, and the look and feel is good. The colors are neither particularly gorgeous nor too pale. The color temperature is slightly warmer. The look and feel of daily movies is still good.

So why did I get it out?

There are two main reasons:

1. The optimization and adaptation of win10 to 4k is indeed not very good. At 4k resolution, the fonts are too small. Enabling scaling can solve the font display problem of some software. However, the fonts of some software interfaces are still very small. A 60cm wide table makes it look blind. The heart is tired. . .

2. Occasionally, the uncle will open a black with old boys and friends, play a game, and play games at 4k resolution, which puts a lot of load on the heat dissipation and power consumption of the notebook itself. Every time I play, I feel that the notebook just takes off. It feels sour and refreshing.

So, on a certain day in June when the sun was burning the earth, I came out and accompanied my first 4k monitor in my life. After

came out, facing the white TN screen of my laptop,I still couldn't bear it, so I started my monitor purchase.

The process of buying things for middle-aged people. First, clarify their needs, then clarify their budget, and finally, place an order! ! !

Requirement:

Size: 27-inch size feels quite suitable, so I still choose 3: do not choose p27-inch _span_span_span4: The 27-inch 1080p is afraid that the display effect is not delicate enough, so I decided to choose resolution 2k

refresh rate: I have been using 60hz monitors before, this time I want to try high-brush monitor

Budget:

After having a baby, the budget for buying electronic products, eh. . . Brothers who have a family and a mouth should all know. . . The budget is relatively unsearchable, and the preliminary budget is composed of: the cost of selling vx2780 + a few hundred yuan (floating), and the whole is not more than 2,000 yuan. If you see a product that is particularly powerful, it’s not too much a problem~ Haha

Next, I will choose the monitor

.Some, some, Xiaopozhan, Du Niang, some treasure, and some Dong started to sweep away.

After half a month of major websites to look at the evaluation to see the sales, understand this price, the parameters of the high-brush display are similar to everyone, 2k resolution, 155hz-170hz refresh rate, 8 shake 10bit color or native 8bit color, 130% sRGB, 95% DCI-P3 or 98% DCI-P3, 1ms gray scale response time (GTG) or 1ms dynamic picture response time (MPRT).

The parameters are the same, can I buy the cheaper one? !

After half a month of research, I found that things are not that simple.

First of all, the difference between the display panels, although the parameters are similar, but the display panels at this price are still very rich, AUO's 2.B, 6.6, 8.2, Innolux's k7e and k7B, LG's first and second generations anoips screen.

The panel characteristics of different models of different manufacturers are also different. For each of the following, I will select a few products and briefly talk about the differences that I have learned during this period.

AUO's panel. I use the MSI e-sports series monitor to tell you the difference. The selected ones are pag272QR, pag272QR2, and mag274QF-QD, respectively. .b, 6.6 and the latest 8.2 panel. Looking at their introduction on their official website, there is a difference in the coverage of the color gamut, and the mag274QF-QD has 2 more usb ports, it seems that the difference is not big? However, the price difference between 272QR and 274QF-QD was over 600.

So what is the difference?

The brightness of pag272QR with 2.b is the highest among the three models. It has hdr400 certification and the color gamut covers 130% sRGB, but the response time of this model is dynamic response time (MPRT) 1ms, which corresponds to GTG time is about 4ms, while the other two models are gray-scale response time (GTG) 1ms, so, his actual gray-scale response time is the slowest among the three,

but its brightness is this is the highest among the three types of .

pag272QR

The biggest improvement of 6.6 compared to 2.b should be the improvement of gray-scale response time, the gray-scale response time increased to GTG1ms.

pag272QR2

Next, let’s talk about the mag274QF-QD with 8.2 panel and the color gamut coverage of 147% sRGB. Looking at the use of various evaluations on the Internet, there is a point mentioned , response The speed is very fast, the smear problem is well controlled, but the color oversaturation is more serious. The changes of

k7B and k7E are more intuitive. I mainly looked at the ASUS and AOCq AOC A Q27, V27G27G27G27G27G27, including two brands of products. , VG27aql1a),The difference is mainly reflected in two places:

(1) K7B has a higher color gamut coverage , which can reach 131% sRGB and 98% DCI-P3. K7E has a poorer color gamut coverage, which is 126 %sRGB and 95% DCI-P3

(2) K7E's panel response time has been improved to GTG1ms .

p0nap panel contrast difference between the two generations of span. During the past half month of surfing the Internet, I learned that the first generation of nano ips is characterized by a particularly high color gamut, strong panel permeability, which makes the look and feel very good, and the response speed is very fast. LG's). The disadvantage is that the contrast is only up to 800, and the brightness is only 350nit. The second-generation nano ips mainly enhanced the brightness and contrast. The full-blood version of the second-generation nanoips screens can reach 400 nits of brightness, and they are all full-blood DP1.4, which can be fully turned on 2K 165-180hz 10bit (the selected target models are Philips 275m1rz pro, Dell_ span2span's s2721dgf and AOC AG273QXP/D), but after looking at it for half a month, I found that there are still a lot of non-full-blooded versions, castration brightness, and castration interface. . . .

to understand the difference of a round of panel1,There are all kinds of things, but for myself, as a consumer, what difference does the difference between these parameters and the panel have on my perception of use?

Yes, I started the second step of understanding the influence of parameters on the senses.

First is color depth

What is color depth?

Color depth (Color Depth) can also be called color bit depth, which is a unit that expresses the number of colors in a digital image by bit number. Bit is the binary unit (or bit) calculated by the computer, that is, the most basic data or message that can be processed in the computer.

This price range is basically 8 shake 10bit or native 8bit. Everyone is the same. The 10bit color looks more natural and smooth, but the 8bit is still a lot worse. I will find for everyone Take a look at the comparison of 2 common pictures on the Internet!

10bit on the left, 8bit on the right (picture from the Internet)

Next is the color gamut

What is the color gamut?

The color gamut of a monitor usually refers to the color range displayed,The percentage in a certain color space.

What is sRGB?

Baidu Encyclopedia is defined as follows:

sRGB (standard Red Green Blue) is a color language protocol jointly developed by the Microsoft imaging giants, , Microsoft, and , Epson, HP, etc. A standard method to define color, so that various computer peripherals such as display, printing, and scanning, and application software have a common language for color.

After reading it, I know that this is a color protocol, or not very specific, so what exactly does he mean?

sRGB is currently the most widely used color gamut standard on the Internet. The default configuration of most software, web pages, browsers, projections, displays, etc. is sRGB. The translation is that the color standards we see on the Internet are all based on the sRGB protocol.

Personal understanding is this

The colors we can see on the Internet in daily use are based on the sRGB standard, and 100% sRGB color gamut coverage means that we can see the resources themselves. If you want to express the color, if the coverage is not enough, then the color you see will be partially missing. If the color gamut exceeds 100% sRGB, but the platform does not have a good color management mechanism, then we look at the pictures and videos on the Internet or web pages. color,There will be color oversaturation, the more the oversaturation, the more serious the oversaturation, and it will look more uncomfortable.

What about DCI-P3?

According to the information I have learned, DCI-P3 is a wide color gamut standard introduced by the American film industry, mainly film color standard, but over time, this color standard It is also used in the gaming industry. If we watch a movie in this color mode, we can see a different feeling from the sRGB mode. If you use this color mode to look at other Internet resources without special color adjustments on the platform, the look and feel will not be very good. Because we have also said before, all Internet resources are basically sRGB standards, and the color ranges covered by different color standards are also different. The yellow line in the figure below covers the sRGB color gamut, and the black line is the DCI-P3 color gamut. The DCI-P3 protocol has a wider color gamut than sRGB!

DCI-P3 and sRGB color gamut coverage (the picture indicates from the Internet)

The third point is the response time

Faster response time, the picture will be smoother, and the smear situation will be better. Due to limited resources, I could not find a physical machine perception comparison, but for the comparison of watching other people’s videos on the Internet, unless you start the test software to slow down, Otherwise, the daily use is really not strong for an elderly person like me. . . .

Summarize the panels of

AUO 2.b and Innolux k7b,The response time is slower and the color is more balanced. The k7e panel improves the response time on the basis of the k7b and reduces the color gamut coverage. The AUO 8.2 panel has fast response time and wide color gamut, but the color is oversaturated. , Nanoips panel, fast response time, wide color gamut, good color, over-saturation but not as serious as AUO 8.2, but low contrast, the picture is prone to reddish.

Although I want to experience a high refresh rate, the display feels comfortable is the first choice, so I first excluded the AUO 8.2 panel display.

nanoips Let's put it aside first, and talk about my entanglement later. . . Okay, so what's left is AUO's 2.b, Innolux's k7b and k7e. K7e currently has too few choices. I learned that there seems to be only and TPV’s Q27g2s/d in large factories. There are 2 panels left-2.b and k7b.

Then I started to learn more about the displays of these two panels. First of all, many of the 2.b and k7b appearances do not have the original backlight, so the quality of the backlight module largely determines the light leakage and brightness uniformity of the display. . . . Ips light leakage is a common problem, this average friend knows it, but manufacturers who work hard on the backlight module can do a good job of controlling light leakage, especially for some design displays of large manufacturers, light leakage control and backlight uniformity are all done. That's good. Like the BenQ that my own desktop is equipped with and the newly released ViewSonic, the light leakage is well controlled. Therefore, some of the models I looked at were basically products with good workmanship from major manufacturers or online reviews.

entered a Acer e-sports King Kong in the past two years. If the light leaks, you can’t see it, and the boot screen can leak into big pants.. . . Difficult to look directly. . . . At that time, I wanted to experience the refreshing feeling of the game brought by the high refresh rate, but it hasn't been used for 2 days. . . The color of the monitor screen suddenly became very gray. After returning to the factory, the manufacturer told me that it was normal! ! ! I was also stunned. Fortunately, it was bought by a certain company. After the sale was available, I directly refunded it. . . The unbearable past~~~[Making Face]

is far away. . . After a lot of selection and selection, the representative product of 2.b panel-Xiaomi's 27-inch gaming monitor, and the representative product of k7b product at the same price-ASUS VG27aq, these two look at the parameters, they are really on the same level. of. Comparing the two, I still prefer Xiaomi's model in my heart. There are three reasons:

1. The whole network is blowing up the workmanship of the Xiaomi display. Below 2000, it is unmatched

2. Xiaomi this The cheaper model is

3. Xiaomi has a 100% sRGB mode, the oversaturation situation will be better than the other model.

Mi Display 27-inch 165Hz version

Seeing here, do you think it’s a basic idea? Want to choose Xiaomi’s 27-inch gaming monitor?

is not hello. Remember the display of the nano ips panel we put aside first? The advantage of the nano ips panel is fast response time and bright colors. The disadvantage is that the contrast is low and the picture is reddish. For my uncle who likes not that rich picture, and the response time difference is so few ms, it is not obvious to give up. him?

However, this is the age of beauty and justice. Remember the Dell s2721dgf I mentioned earlier? Perfect appearance, exquisite workmanship, and good look! ! ! especially,I watched some evaluation and picture comparison videos. Although the picture has some redness, the overall oversaturation is not serious, and the look and feel is good. Although there is a black screen problem, but the small broken station has an up master to do an experimental analysis, and the black screen problem can be solved.

Uncle is really too good at Dell’s face. . . . Xiaomi's e-sports monitor is like an industrial cold-style suit, and Dell's s2721dgf is like a sunny and handsome fashion brand, it is difficult to choose.

Based on the idea that money should be spent on the blade and every cent should be spent worthwhile, I originally planned to order a 27-inch display for Xiaomi. However, I ran into several large local Xiaomi homes, but none of them When I touched the real machine, I just saw someone on the Xiaopo station posted a 1-year experience of using the 165hz version of the Mi Display 27-inch display, pointing out that the color was reddish; the magnetic cover on the back of the display after being used for a long time on the post bar, suction It becomes fleshy and can't be covered. . . (This is really the last straw that crushed the camel)

Yes, the uncle finally increased the budget and fell into the arms of Dell! ! !

is actually the result of comprehensive consideration. Both of the workmanship is at the top level in the same price range, and each has its own shortcomings. Considering Dell’s after-sales service, it is more secure that it is only replaced for three years. After the goods arrive, I will give you another one to open the box.
