In the past six months, the most high-end display products on the LCD display market have been Apple's Thunderbolt Display. However, on the official website of the mainland, we can only see the old LED Cinema Display. In terms of interfaces, the new Apple 27 has more Thunderbolt interfaces, as well as a Firewire 800 port and an Ethernet port.
Continental Apple's official website LED Cinema Display offer 7698 yuan RMB, while Hong Kong's upgraded version of Thunderbolt monitor offer 7688 Hong Kong dollars
Thunderbolt Display has been on sale for less than half a year, and the LED Cinema Display, which has been replaced, has already seen a significant decline in price, which is also reasonable. Now the price of this 27-inch display on the mainland official website has dropped to 7698 yuan, which is almost the same as the "price figure" of the Thunderbolt Display on the Hong Kong official website (of course, the exchange rate difference of 1,500 yuan has been neglected here).
On the other hand, if you take the LED Cinema Display to compare the iMac with the same size and low price of 12998 yuan on the mainland official website, the difference between the two 5300 yuan is obviously not the price range of the Apple mainframe. Some people say that the panel is different. Some people say that the same IPS panel is just a castration in power supply and signal transmission. This makes Xiaobian associate with many Apple screen LCDs that are popular in the market recently. Some are Taobao personal assembly models, and some are Apple screen LCDs produced under the company's name, just like the recently-sold Jeolla Asia E270IPS.
Seeing this picture, I believe the netizens have already understood that the LED Cinema Display and the iMac are different.
So, will the "Apple Screen" LCD use the iMac screen, and it is different from the Apple LED Cinema Display in terms of image quality? This issue will be revealed next week, but before this series of mysteries is revealed, we must first evaluate the LED Cinema Display that has just arrived. In fact, we have had detailed evaluations on foreign websites earlier, but we have not tested the actual results in China. Quality performance).
Original packing box! Apple LED Cinema Display
Just last week, Xiaobian got Apple's 27-inch LED Cinema Display from a distributor in Zhongguancun. Today, Xiaobian first tested its shape and basic image quality, and then thought about comparing it with the Lianya E270IPS. It should be noted that the Apple 27-inch LCD that arrived at PCPOP this time castrated the built-in speaker compared with the original product, so the store price is naturally much cheaper than the official website's 7698 yuan, only 6600 yuan, the warranty time is also One year, it is just a store insurance.

At the bottom of the box is the word "Cupertino", which refers to Cupertino, where Apple's global headquarters is located. From the point of view of the product packaging, although there is a slight difference from the original (no built-in speakers), the quality of the product is still certain, and the next page begins to unpack and check one by one.
The aluminum body is simple and beautiful! Apple 27 å‹ fuselage analysis
The Apple LED Cinema Display measures 27 inches and 16:9 with a resolution of 2560×1440. It is also a high-performance LED+IPS combination with a display source of Mini DisplayPort. The shape gives a feeling of living off the crafts, the screen itself is like the enlarged version of the iPad, the black border, the back, the bracket, the base and the screen are self-contained, and the all-aluminum body is built.
From the back view, it can be found that this product provides three sets of USB 2.0 interfaces, and the center of the bracket also has a round hole for the cable management frame. In addition to a power jack, there is a three-in-one cable that serializes the back of the screen by default, as will be mentioned later. The fuselage that is slightly raised back is very round and shiny. At the top of the stand, the "bitten apple" is naturally the common Apple Logo.
The display features an audio-enabled Mini DisplayPort, a universal MagSafe (up to 85W), a USB 2.0 three-in-one output cable, and a universal LCD power cord for powering it.
Apple's 27-inch LED Cinema Display has a large tilt angle of 5° from the top and 25° from the bottom. Regardless of the view from the top, its viewing angle is far better than the adjustment range of ordinary household LCD, especially in the view angle, many home LCDs can only be perpendicular to the desktop.
Camera + microphone Apple 27 å‹ body details
At the top of the front screen of Apple's 27-inch LED Cinema Display, there is a built-in iSight camera and ambient light sensor. The built-in camera is very convenient for video chat. Of course, for this Apple 27-inch LCD without speakers, you need to connect headphones or speakers to your host.
The small hole on the left side of the camera is an ambient light sensor that intelligently adjusts the brightness of the LED Cinema Display based on the room environment. This gives the best brightness in any situation while consuming the least amount of power.
The top hole is the microphone
After all, LED Cinema Display, only 3 x USB 2.0 interface on the back
The picture shows the interface cable part of the LCD monitor. In fact, there should be a white power cord that is not plugged in, and the default connected cable is what we call "three-in-one", which is the following picture:
LED Cinema Display with universal MagSafe power connector for charging a laptop (middle), easy-to-connect Mini DisplayPort cable (right) and USB 2.0 port (left)
It can be said that this three-wire cable has become the benchmark for the convenience of LED Cinema Display. You can connect LED Cinema Display with any current series of Mac laptops and desktops, including MacBook, MacBook Pro, MacBook Air, iMac, Mac mini and Mac Pro. However, if you connect a regular PC or notebook, you also need a graphics card with a miniDP interface or patch cord support, the interface convenience is reduced.
Black field white balance test Apple 27å‹ LED transparent feeling strong
Half an hour after preheating the display in the darkroom, we first connected a MacBook Pro and tested the product. However, the software that suffers from its i1 color calibrator and gamma test does not support the Mac platform, so only the brightness, black field, contrast, color gamut and power consumption are recorded. On the second day, Xiaobian found another set of Win7 platform for testing. The same picture was taken in a blackened closed environment:
In the all-white environment, Apple's 27-inch LED Cinema Display has a strong sense of transparency, but the brightness of the luminescence colorimeter BM7 is only 300 cd/m2, failing to reach its nominal 375 cd/m2. However, with its highly environmentally-certified mirror glass screen, the picture quality is significantly better than that of ordinary LCD.
The shortcoming is also obvious, that is, it is easy to reflect. Especially when the brightness of the lamp in the house is very high, when the light source is unstable, it should be noted that the brightness of the light in the home is not too high, and the light source is not complicated, and the screen is best placed in the room.
Friends familiar with the evaluation are clear that LCD monitors have now abandoned the test of brightness uniformity. This is because in the case of LED backlight, the difference in brightness uniformity of a liquid crystal is difficult for the naked eye to recognize subtle differences. . However, this is not the case in the all-black environment. We have seen a relatively obvious light leak on the left side of the lower border of this LCD.
However, the actual observations are not so obvious, which is also due to the fact that the camera exposure time is slightly longer. The overall uniformity of the screen during actual viewing is still satisfactory. If the full score is 10 points, the result of light leakage should be around 8 points. In addition, whether it is Mac or Win7 platform, the black field brightness value is 0.274cd/m2, and the black field value is very stable.
After the direct division by the brightness black field, the contrast of this LED Cinema Display is 1095:1, which is still much higher than the nominal 1000:1 level. It should be said that this is also related to its mirror screen. .
Red, green and blue three primary colors interpretation! Apple 27 å‹ color is good
The first thing to note here is that due to the adjustment of the parameters when the camera is photographed, the actual photographed color and the original image do not necessarily have a perfect color performance, but the relative performance is already very close to the actual performance, we will also record the time when the photo was taken. Feelings:
Red original pattern
Apple's 27-inch LED Cinema Display is darker than the original image, and the red color seems to be like a light-emitting red object.
Green original pattern
Apple's 27-inch LED Cinema Display's actual green performance is slightly yellowish and white compared to the original image. The color is naturally diluted compared with the green color in the original image.
Blue picture proofs
Apple's 27-inch LED Cinema Display's blue is slightly shallower than the original image
Maybe seeing it here, you will say that the actual color performance of the Apple LED Cinema Display is not at the same level as God. This is indeed the case. After all, we have actually tested it, its gamut range accounts for 83.67% of the NTSC 1953 range, and does not reach the wide color gamut level. It's no wonder that it uses white LEDs as backlights.
However, if you change to an ordinary LCD display, the original picture of RGB three primary colors will also be compared, you know that the color gamut of about 75% of the liquid crystal has a significant difference in color reproduction.
FAQ! Analysis of the color of Apple LCD panel
The panel data in the chart comes from the tftcentral website
The first page of the article has mentioned that the iMac uses the first row of the panel in the table above. Earlier, we also saw that the promotion of Lianya mentioned the use of Apple screen, supporting 102% of the color gamut performance, which is obviously a fallacy. Because the panel of the 102% color gamut in the above table has a response time of only 5ms, CCFL illumination is also used. The official promotion of Apple LED Cinema Display clearly shows the 12ms gray-scale response time, which means that the panel used by LED Cinema Display should be "LM270WQ1-SDDA", so 83.67% of the color gamut performance is its actual value. There is no 20% difference in the removal error.
However, some people will say why the color of the Apple LCD looks particularly bright and bright, which is of course not only the gamma color support, but also its gamma color transition, color temperature stability, and the mirror screen of the outer layer of the screen itself. , enhanced color saturation.
We see that the gamma of the Apple LED Cinema Display is excessively smooth, and the RGB three primary colors are almost completely coincident.
The shaded area in the figure is the color range of the LED Cinema Display.
Power Test / Final Summary Apple 27å‹ Personal Insights
In the actual test, according to the calculation formula of Eff=brightness×area/power consumption, we obtained that the energy efficiency is 300×0.2/77.50=0.77cd/w, and the standby state is 1.8w, which fully complies with the China Energy Efficiency Label Level 3 certification. However, the actual test found that the fuselage is hot, which is somewhat confusing. In terms of specific image quality and temperature, we will also compare the day with the United Asia E270IPS.
And when it comes to the product that the dealer sent the test itself (there is no built-in speaker compared with the licensed product), not to mention the many advantages of the manufacturer's manuscript, the actual feeling is that the shape and material of the fuselage are indeed called crafts, but also other brands. The trend of imitation. The camera and microphone also well interpret the SNS function of LCD for video call and chat, the three-wire interface on the interface, the high saturation color of the mirror screen, and the accurate color reproduction. The high resolution of 2560×1440 is Deserved to be respected. As for the miniDP, it is still relatively small, and Apple LCD is expensive. This is a matter of opinion.
