The younger brother hasn't posted posts on the Internet for a long time. SMZDM and other forums have also gradually reduced their responses. The reason is not that the younger brother has become lazy. Instead, the keyboard of the Lenovo Zhaoyang K46A notebook computer that accompanied the younger brother for 7 years has had a problem. There are a few keys on the screen that are a bit less sensitive and the typing is very inconvenient. It seriously affects the enthusiasm of the younger students to send homework and posts (in fact, it is lazy). In order not to affect the work and Internet posting, it is decided that a long grass will have a DreamColor screen. HP Workstation (actually it is too lazy to repair the original computer keyboard).
About the DreamColor screen, the younger brother first saw that it was a few years ago that Lin Zhihu Great God wrote a post about DreamColor2 technology:
Billion-colored dream - HP DreamColor: First, on the other hand, he is also a chance to use 8770w, could not bear to revise the DC screen, there are some experience. In order to write something for himself, although taking the liberty to abruptly show off the West, Diyer, who is self-proclaimed with a light geek spirit, is not happy? The laughter is generous, only for the purpose of throwing bricks. People always hope to record and truly restore the beautiful things they can see. So there is a huge pit of photography. The demand for high-quality display terminals is also Lin Zhi Hu | Likes 163 Comments 69 Collections 191 View Details Although I don't understand the technical explanations, I feel that HP's DreamColor technology and Dell's PremierColor are basically at the top of the laptop display effect pyramid. Thinking about the younger brother's usual work, the time spent watching TV and playing at home is rare. In addition to being a productivity tool, the laptop is also the most used entertainment tool. The display effect of the display is directly related to the entertainment experience. Ever since, it has been wondering whether to start with an HP workstation equipped with DreamColor technology or a Dell workstation equipped with PremierColor technology, but PremierColor technology seems to gradually fade out of the public after the M6800, and now the screen that can customize PremierColor technology looks like It is not based on the color gamut and color scale, but on its resolution. . . So the only alternative is the HP Zbook Workstation that has evolved to third-generation DreamColor technology.
With the goal, the younger brother began a long and hard road to purchase. It can be said that this experience of buying a computer is the youngest brother has experienced the most troublesome shopping experience. The first is that the Zbook15 with the DreamColor screen is almost impossible to find on China's online shopping platform. The only option is the Zbook Studio, but the configuration is extremely high, the price is almost 4W, and the budget cannot be fully held. Later, through the official microblogging of HP workstations, they obtained the manager contact information for their custom workstations. They wanted to operate in a customized manner. However, the manager responsible for workstation customization later told the younger brother that the minimum number of machines for DreamColor screens was 8 , The younger brother or look at the 4W Zbook Studio. As the younger brother kept searching online for information on the DreamColor screen, he inadvertently saw a relatively low-end configuration at a certain mall. The Zbook Studio equipped with a DreamColor screen was sold. The owner said that he could offer discounts to the 1W9 seller. Watching the heart on the moment, but let the younger brother surprise is still behind him, the boss said that he is Hewlett-Packard in South China workstation senior agent, can help me customize the Zbook15 with DreamColor screen, according to my configuration requirements customized down costs only 16800, specific Configure as shown below:
Because the younger brother usually does not play games, usually work and office with Office series software, PS and the like, so the performance requirements are not high. The only thing that requires a higher screen is the screen. After negotiating with the owner of the shop, the younger brother immediately started to order. According to the boss, custom machines generally take 21 days to be ready and shipped. Anyway, at that time, the younger brother Zhaoyang K46A was able to make do with it, so he slowly waited for the 21 days to pass quickly. However, after 21 days, the logistics of a certain mall hasn't shipped the news. Ask the boss What happen. As a result, the owner came to DreamColor screen factory has not been stocked. Now, if the goods are transferred, at least 20 factories are required to apply. Tone.
After tossing for a month, the purchase of new notebooks feels back to the starting point, and the Zhaoyang K46A keyboard failure on hand is worse than before, and can no longer be dragged on. Ever since the younger brother went online to search to see if there are other spot DreamColor screen machine, and later to the United States HP official website to see, actually there is a Zbook15 G3 with DreamColor screen for sale, but the configuration is extremely high, the price is very affordable . The configuration and prices are as follows:
According to the exchange rate at that time, the price of the machine has not yet exceeded 1W5, and it was found that the US Emperor Hewlett-Packard was the conscience. So almost immediately contact Ma Yunjia's purchasing orders, but. . . . There is a problem, the former younger brother often used that purchasing and the younger brother said that HP Mall needs US and Mexico to order, they can not operate shop. No way, only to quickly find the United States and the United States and Canada in the United States and Ma card purchasing, the final to find that the total cost of purchasing my newspaper is 17,330, is not too expensive, do not want to toss the order quickly. but. . . . After the order was placed, things didn't develop very smoothly. The first thing was that the state where the delivery of goods was received had suffered snowstorms and traffic. The machine took him five days before sending it to him. Then when he made the transfer, the system of the transshipment company came out again. Failure, dragged on for almost five days. At last I arrived and I was caught by the Customs. Fortunately, the tax rate of the notebook was not high. Nearly 2W of computers were used, and the final tax was only 300 yuan. Think of the younger brother's $ 6,000 air purifier and made a tax of 700 yuan at the customs.
After 2 months of tossing finally, this HP Zbook15 G3 DreamColor finally finally reached the younger brother's hand.
Appearance GalleryConcerned about the long-distance transportation to destroy the sophisticated DreamColor screen, the younger brother specifically added a 180 yuan reinforcement package, so after the arrival of the two boxes, the outside of the box is reinforced with a lot of buffer foam inside
In the box inside HP, the foam was used to hold the machine in a black foam. The inside of the box was very tight and the protection was still quite in place.
Take out the machine and wrap it with a plastic bag with a fragile sticker
Excited to open the screen cover, I really worry that the screen will bump in the transport process, but this worry has not happened
The A surface of the fuselage consists of two materials, the middle one with a small dot of metal material and the black one with a plastic material. The value is not as good as the 8770w of the EliteBook of the year, but the new design should have advantages in receiving wireless signals.
Body B is a plastic material, the overall texture is good.
The B-side and OLUFSEN audio logo on the upper left side of B-side, this time HP puts a lot of effort into the sound of the Zbook workstation.
The Logo of DreamColor in the upper right corner of B surface indicates that the screen of this machine is by no means a good one.
After opening the screen as a whole, the C surface is made of metal material, which feels very solid. The keyboard has a numeric keypad, a very practical and convenient design.
On the left side of the C side, there is a small logo of the Zbook, which is sprayed up. I don't know if it will fade after a long time.
On the right side of C face is Intel's dog skin ointment and fingerprint recognition module. Fingerprint recognition module should be optically inductive. The experience of use is much better than that of Zhaoyang K46A.
The screen axis did not adopt the design of the metal hinge of the previous generation Zbook15 G2. Instead, it adopted the sunk design that the younger brother hated very much. This kind of sunken screen axis design is a trend brought by the apple, but it is very much for the workstation. There are three reasons for the brain damage design: The first screen opening angle cannot be 180 degrees (unless there is a special design)
The second is if the machine's heat vent is on the back, the hot air is blown directly onto the screen. I don't know if the current DreamColor3 screen is using an RGB-LED backlight system. If it is an RGB-LED backlight system, the speed of this failure is very touching.
The screen has just been covered with a protective film. The filming technique is obviously not an ancestral one.
The third problem with using sunken screens is that the support stability of the screen is reduced. The performance on the Zbook15 G3 is that the screen is shaken after the screen lid is opened, and at the same time, the rotating screen shaft can hear the plastic deformation sound of the beak.
Behind the fuselage there is a Mobile Wordstation word, not the color of the previous EliteBook that so deterrent, feel that the HP workstation shape design over the past few years have become increasingly. . .
This generation of Zbook15 is very rich in interfaces, there are two lightning interfaces, three USB3.0, one HDMI and one VGA, can be described as the interface between the old and new standards are taken care of, now many notebooks in order to do thin and cut corners, USB interface With one, but not with the optical drive, and now a lot of external optical drives are dual USB port power supply, if you take a CD to read, it really only left to dry eyes.
The power indicator is next to the power connector, but personally prefer the design of the indicator above the power transformer.
It is said that the previous generation of DreamColor2 power has 60W, not the workstation can not play this kind of electric tiger. This generation of DreamColor3 does not know how big the power is, but has been equipped with a 150W power supply at random, close to the power specification of low-end desktop computers.
The power transformer is manufactured by Delta. Because it is a US-made machine, the power plug that comes with it is also an American standard. In domestic use, it must be equipped with a conversion head.
Returning to talk about the fuselage, the fuselage status indicators are all in front, the angle is designed to be very unsatisfactory, and the lights are very dark, it is very difficult to see the lighting status of several status indicators in the end. Feel the HP workstation designers really should learn ThinkPad, Fujitsu, Sony these small Japanese design notebooks to see how others are humanized design.
Body D surface material is metal, the overall design is relatively simple, two cooling fans are hidden under the cooling grille. Unfortunately, the previously acclaimed tool-less design of the EliteBook has been eliminated. Nowadays, screws on the D surface are all very difficult to find the hex screws for the screwdriver. It is very difficult to open the cover by yourself.
This machine's non-slip rubber pad design is more interesting, is a full circle around the entire D surface, and there is a certain three-dimensional shape, it is estimated that the difficulty of processing is not low. However, there is no egg use. . . . On the glass surface, the anti-sliding ability of the Zbook15 G3 is not entirely against the Zhaoyang K46A used by the younger brother. Oh, right, the younger brother here started to talk about the previously used Zhaoyang K46A. The Zhaoyang laptop was a commercial notebook brand that Lenovo had before buying IBM's personal PC business. After Lenovo bought the IBM personal PC business, Zhaoyang laptops have many technologies. Is shared with the ThinkPad, such as anti-skid pad is used and ThinkPad similar.
The younger brother does not have a hex screwdriver so the disassembly session can not be carried out. The following is the disassembled Zbook15 G3 found by younger brother on notebookcheck.net: https://HP-ZBook-15-G3-Workstation-Review.162600.0.html
The internal structure of the fuselage and the materials used for workmanship are still relatively good. It is, after all, a workstation.
Say this machine is not so much, it should give it to promote a little "positive news", first of all is the BANG & OLUFSEN sound, sound quality is indeed quite awesome. The reason for the force is that HP has divided the sound of this notebook into two parts, the tweeter and the bass unit. The tweeter is located on the C side of the camera and above the keyboard.
Two bass units are placed in front of camera D
In addition, the sound card output thrust is also very enough, the younger brother Bose SoundTrue earbuds to listen to listen, tone, strength is much better than on a desktop computer.
At the software level, there are also BANG & OLUFSEN management pages that are intuitive and easy to understand.
It is no exaggeration to say that the DreamColor display of this Zbook15 G3 may not be the best notebook with the best picture quality, but this set of BANG & OLUFSEN audio is definitely the best one among the younger brothers.
Another commendable part of the Zbook15 G3 is the touchpad, which is very smart: It can automatically recognize whether you touch the touchpad by mistake or actually need to use it. If the touchpad is in the wrong state, the computer will Prompt whether to close the touchpad; if you touch the touchpad with the touchpad off, when the computer recognizes that you need to use the touchpad, it will automatically open the touchpad.
The touchpad's touch texture is also very comfortable, and the pointing stick in the center of the keyboard is also very easy to use.
In addition, the polished frame around the body is very eye-catching, is a good industrial design element
Originally for a notebook computer, especially workstation-class notebooks, CPU, memory, graphics and other performance should be the first to talk about, but because this machine is using the DreamColor screen, so the younger brother would like to talk about the display.
Before talking about the effect, the younger brother would like to talk about the development process of DreamColor technology of Hewlett-Packard's mobile computer. The content is mainly the younger brother's own finishing through the past few years. If there is any inaccuracy, please ask the gods to point out;
The initial generation: DreamColor1, the first generation of HP mobile computer DreamColor technology should appear around 2009, can be installed on the EliteBook workstation, the specific model of younger brother can not remember is 8730w or 8550w. RGB-LED backlight, TN material panel, 8bit color, 1920X1200. It is said that the NTSC color gamut can reach 130%, and many of the top LCD TV color gamuts of the same generation are still far from this value. (Note: At that time, the Japanese TV picture quality war, the era of flat-panel TVs can easily spike the current market For models such as the same RGB-LED backlight system, the NTSC color gamut of the Sharp XS1 using the higher-order 14-bit panel can only go up to 114%.
The second generation head: The DreamColor2 mobile computer screen should initially be available on the EliteBook 8770w with a resolution of 1920X1080 (a 16:9 screen with a fish screen), an RGB-LED backlight system, an IPS material panel, and a 10bit color bit. DreamColor2 can be said to be the pinnacle of notebook LCD technology, 10bit color LCD panel is the top panel of the desktop monitor standard, because the computer graphics card can not output such a high color digital signal, HP for this computer In addition, a decoder board was additionally installed to convert signals. DreamColor2 has a very good performance in the color gamut. At the same time, thanks to the 10bit panel and the independent decoder board for processing signals, DreamColor2 is almost in the notebook display in terms of color accuracy. It is basically the factory DeltaE is below 2. The color of the school can be reduced to 1 or less. Nowadays, besides the Microsoft Sophie Book and the Apple MacBook Pro 2016, no display screen has such a high degree of color accuracy, even if the true color accuracy can reach this level. The color space is terrible.
Three generations of orders: Zbook Studio, Zbook15 G3, Zbook17 G3 are optional. Resolution 3840X2160, GB-r LED backlight system (possibly), IGZO+IPS material panel (possibly), 8bit color (possibly), PSR self-refresh screen technology. There are very few technical descriptions about DreamColor3 on the Internet. Regarding its backlight system, the younger brother saw the backlight system description of DreamColor3 on the customized page of HP's official website Zbook Studio. It is a GB-r LED. GB-r LED can be regarded as It is a castrated version of RGB-LED. In terms of color performance, GB-r is definitely not as good as RGB. However, GB-r has lower cost and better attenuation than RGB. Unfortunately, this page is no longer visible on the HP official website in the United States. In addition to the material of the screen, the younger brother detected by Master Lu found that this panel comes from Sharp, the model is SHP1445
This screen does not find any data on the screen library. If it is based on resolution, size, and manufacturer inquiries, the matching panels are all IGZO materials. At the same time Dell's current Precision workstation can be equipped with PremierColor screen, in size, resolution and HP's DreamColor3 highly consistent, Dell's official website for PremierColor screen is annotated IGZO material, so the younger brother boldly speculated that DreamColor3 is using IGZO Material IPS arrangement screen
In addition to the color of the screen panel, the younger brother found in the screen library Sharp the same size and the same resolution of the panel are 8bit color panel, before the machine just arrived, through HP's own system software tool HP Performance Advisor The color space of the query screen is also 8bit, but unfortunately the software has recently revealed a failure when it is open. There is no screenshot before it can be opened. . . . .
From the literal data point of view, DreamColor3 has a step backwards from DreamColor2, but it is good or bad to know it beforehand. School color instrument brother is still looking for a domestic prodigal forum and God of the God of home appliances to borrow, so the color gamut, color accuracy, backlight uniformity there is no way to test, and the following screen shot is also not the color of the original DreamColor3 screen performance, Although there is no instrument-assisted testing, it can also explain the problem because the difference that the naked eye can feel is large enough.
The first is the comparison with Lenovo Zhaoyang K46A before the younger brother. Next to the HP Zbook15 G3 DreamColor, the Zhaoyang K46A was dubbed as a black-and-white TV. . .
Above is Girls Generation's "The Boys" 1080P MV, which uses STORM to open the left eye. The following are the “Land of the South, the Realm of the Sky, and the Stones of the Ancients†of Ding Da Shen, the Dajiang community.
Http://bbs.dji.com/thread-118107-1-1.html, playing at 1080P resolution:
Can clearly see that the two are not an order of magnitude rivals, and then compared with another mobile device - iPad Air, before watching the Internet that the iPad Air NTSC color gamut can reach 94%, color accuracy also has a good performance. The video of the comparison is still the "Great South America Line, the Realm of the Sky, and the Stones of Ancient Times" by Ding Daxin of Dajiang Community.
iPad Air is still not an adversary, and some brothers may say that the Zbook15 G3 DreamColor is reddish. In fact, this is not the case. This situation is mainly caused by the camera's camera being unable to use the correct white balance value at night. In fact, through the naked eye, Zbook15 G3 DreamColor should be somewhat yellowish.
The following is the link to the desktop device. The first one is the LG monitor of the younger brother's desktop computer. It looks like the picture quality of the LG monitor is better. In fact, it is because the brightness of the LG monitor is higher, when the screen is shot. More details of the screen are captured by the camera. If the naked eye is contrasted, the LG monitor's screen appears whitish and the color is too light.
The final appearance was a display device with the image quality closest to the Zbook15 G3 DreamColor, a Sharp BK7 LCD TV produced in 2008, a Guilin Sixth-generation ASV LCD panel, and a CCFL backlight. The following screen shot of “South America, Sky, and Ancient Stones†was shot at night. The hand was a little shaken and the picture was pasted. But from the color point of view, the two are relatively close, Sharp BK7 because of the high brightness, the camera shot after the color is slightly lighter, in fact, the two colors are very close.
The screen shot of “The Boys†below is much better in the daytime. It can be seen that the Sharp BK7 still has a very high picture quality. After experiencing the Japanese television quality wars, the picture quality has several brushes. . In some scenes, the Sharp BK7 even has a higher quality than the Zbook15 G3 DreamColor. After that, when you borrow the color correction instrument, you must also look at the TV school. I believe the sharp BK7 image quality after the school passes. Have better performance.
This generation of DreamColor screen relative to the previous two generations of DreamColor, the biggest place to improve should be the resolution, PPI has been on the 280, usually operating the computer can not see the pixels, there is no any jagged sensation, the following close to the screen to take pictures After zooming in, you still can't see the pixels and sawtooth. The picture is very delicate. 
However, high resolution has brought another problem - software compatibility, not all software can completely match the high resolution of the 3840X2160. In the software used by the younger brother, Mito Xiuxiu appears to be incompatible, and the displayed image is simply to blink.
The little boy who wears a presbyopic glasses can't see clearly. He wants to close it and it costs the boss. . . .
DreamColor3's management software is upgraded to HP DreaColor Assistant. The function page is much simpler than the previous HP Mobile Display Assistant.
The above mentioned that the younger brother did not have a high pursuit for the performance of the notebook, so the younger brother in the performance test did not do a very professional test on such PCMark, 3DMark, Cinemabench
More surprisingly, HP's Turbo Z SSD (in essence, Toshiba's PCI-e SSD) performs very well. In daily use, it also finds that the speed of loading is faster than that of the Intel 520 series SSD on the Zhaoyang K46A. Much faster. 
In terms of heat dissipation, Hewlett-Packard has fully enabled the design of dual cooling fans in this generation of Zbook workstations in an attempt to change the previous problems that have been criticized for poor heat dissipation. For the younger brother's use in the recent period of time, Hewlett-Packard has achieved his desired results. .
The temperature and pressure test was performed at a room temperature of about 23 degrees Celsius. The maximum temperature of the CPU was 72 degrees, and the temperature of the video card was 53 degrees. The fan noise during the temperature and pressure test was not high, which was lower than that of the Zhaoyang K46A with a single cooling fan. However, in the Zbook15 G3 DreamColor cooling fan, the noise is slightly higher than that of the Zhaoyang K46A.
At the same time, the thermal insulation of the C surface of the Zbook15 G3 DreamColor is very good. No matter how long the computer is used for a long time, the entire C surface is kept very cool.
Although the Zbook15 G3 DreamColor is equipped with a bunch of high-performance hardware, it also drags a large consumer--the 15.6-inch DreamColor screen, but the battery life is very powerful. Even when the high-performance mode is turned on and the screen brightness is maximized, there is no problem at all in supporting normal strength work in the morning or one afternoon. This is much better than the previously used Zhaoyang K46A, and the K46A's ideal state is estimated to support two and a half hours.
Although it was a computer that tossed the computer for two months, there was a place where the younger brother was satisfied, and a place where the younger brother was not satisfied. The following advantages and disadvantages are summarized by the younger brother based on his experience during the recent period of time. If he still finds new advantages and disadvantages during use, the younger brother will make up for it further.
Advantages: Powerful performance, excellent heat dissipation and heat insulation, there is a legendary one billion color DreamColor screen Gat. Spike BANG & OLUFSEN audio for ordinary laptop speakers, very smart touchpad, solid and reliable body.
Disadvantages: The position of the computer status indicator is not enough for humanization. The design of the sunken screen axis leads to the bad consequences of the hot air blowing from the heat vent to the screen and the screen is not stable enough. The anti-slip performance of the D-side mat is not good enough. The rate has caused compatibility problems in some software.
