Before turning to the survey, we need to make one clarification. In the test lab came Monitor ASUS PA279, while on sale in Russia and the world will fall Monitor ASUS PA279Q. In fact it is – one and the same monitor, and the presence or absence of the letter Q in the name of the model will depend on the region where the monitor will be sold
Overview Monitor ASUS PA279 (PA279Q): Plug-and-Play. According to the specifications, we have another monitor with the matrix AH-IPS, 27-inch and a resolution WQHD. At first glance, nothing special, unless you consider the type of lighting – is GB-LED (that is, we will talk about later). It is thanks to her producer matrix AH-IPS was able to get an extended color gamut, which can not be achieved with the same matrix and backlight type WLED.
A couple of words about what GB-LED (another name – GB-R LED) is different from other types of LED-backlit LCD screen. The most primitive version – WLED, the so-called white LEDs (actually they emit blue light passing through the yellow phosphor). The spectrum of the “white” LED has a pronounced peak in the wavelength range corresponding to the blue color. Brightness in other bands have WLED enough to reproduce the panel could really saturated red and green colors. As a consequence, from the panel on the basis of WLED can expect at best coating colors within sRGB (or even less, that very often occurs in low-cost laptops and tablets).
RGB-LED backlighting is based on the triad of red, green and blue LEDs and allows to achieve such rich colors that are unattainable even for the WCG-CCFL (cold cathode lamps wide color gamut, 98% Adobe RGB and 102% NTSC 1931 ). Used RGB-LED is extremely rare for several reasons: the high price, size, power consumption and non-uniform degradation of LEDs of different colors.
GB-LED – a completely new technology that LG is introducing in panels of type AH-IPS. As follows from the abbreviations used here blue and green LEDs, partially covered with red phosphor.
The spectrum of such illumination forms three peaks at wavelengths corresponding to the primary colors of RGB, of which the “red” peak is less pronounced than the other two. Like RGB-LED, GB-LED matrix gives color gamut, superior performance panel with lamps WCG-CCFL, namely – 99% Adobe RGB and 104% NTSC 1931.
Of course, there have new lighting and no minuses – it still end, unlike the RGB-LED, which is an array of LED triads, distributed behind the polarization layer films and filters. So, the monitors with GB-LED can meet overexposed area at the edges of the screen and all the other cons end backlighting. In addition, at the time of this writing monitors GB-LED sale occurs less than two dozen, and they are not cheap – 20 thousand rubles. Average price ASUS PA279 is around the mark of 33 thousand rubles, which is quite a lot compared to the bulk of the 27-inch monitor with a resolution 2560h1440 pixels, but quite acceptable for a professional model with an extended color gamut.
⇡ # Specifications
Judging from the information that we found on the Internet, in the ASUS PA279 set matrix LG LM270WQ3-SLA1. The same matrix is used in the other monitor c resolution 2560×1440, such as Dell U2713H. Brightness subpixels LM270WQ3-SLA1 encoded by 8 bits, but through the use of technology A-FRC (Advanced Frame Rate Control) color coding accuracy increased to 10 bits per channel. AFR many years is not new and is also applicable to the 6-bit TN-matrices, in order to obtain a standard 8 bit. AFR also called “temporary dithering,” as additional gradation achieved by sub-pixel flicker at high frequency. To emulate the sRGB mode and adjust the gamma curve monitor uses a 14-bit LUT.
The stated maximum brightness in our guinea is 350 cd / m2, which is considerably above the average in the market. Special attention is given response time GtG – 6 ms, which is an excellent indicator for the IPS-matrix (TN-panel with a refresh rate of 60 Hz are in the range of 2-5 ms). However, in the ASUS somehow did not specify a static contrast ratio, bringing it a dynamic value, 100,000,000: 1. However, looking ahead, we can say that with a static contrast ratio of our experimental procedure is complete. Also, the potential buyer must bribe the extended color gamut and factory calibration of the display, whereby Delta E value should be less than two units.
A few things worth mentioning. Firstly, this connector Daisy-chain DisplayPort – it is suitable for the creation of multi-monitor configurations, when one monitor can be connected to a nearby display, and not to the video (including in games using AMD Eyefinity or NVIDIA Surround). It will also be interesting built-USB-hub and a huge number of USB 3.0 type A, provided by the manufacturer. The monitor their whole six pieces – even on gaming laptops universal ports occurs less. At the same time one of the universal connector can be used for fast charging of mobile gadgets due to the increased current. Also have a pair of built-in speakers total capacity of 6 W, a signal which is applied on the interface HDMI.
The last highlight of the monitor will be built in card reader (MMC / SD / SDHC / SDXC / Memory Stick PRO / Memory Stick PRO Duo / Memory Stick PRO-HG / Memory Stick XC). It turns out that when you buy ASUS PA279 can be a good idea to save on a few accessories. Of course, if you need them.
⇡ # Package Contents ASUS PA279
Delivered to monitor large and brightly colored cardboard box with a small handle. On the packaging of the monitor, as usual, shows all his strengths.
Package at ASUS PA279 received almost royal: the box has even visor to protect from glare – all as adults. That’s just to get rid of bad “almost” in the box is not enough corporate calibrator. While, on the other hand, his absence can be justified by the fact that such devices are quite expensive – from 5000 rubles, and the price of the monitor they can increase accordingly.
The cables have been found in the box with the monitor:
Dual-Link DVI-D to Dual-Link DVI-D;
DisplayPort to DisplayPort;
DisplayPort to Mini DisplayPort
USB type B to USB type A;
Audio cable mini-jack to mini-jack.
Separately want to mention cable DisplayPort to Mini DisplayPort. Usually it is very difficult to find in retail stores, not to mention the monitor box. He, by the way, is compatible with the “MacBook” and other computers with Thunderbolt ports in view of the fact that the latter can output a signal DisplayPort.
In addition to the cables, complete a driver disk and a variety of papers, warranty card, manual and test report basic parameters of the monitor. For example, there is written that the middle parameter Delta E at this cooler has to be at least two units. But, of course, this report does not refer to our instance, and all monitors ASUS PA279. However, the measurement of Delta E is part of our new technique of testing monitors, so this option, we’ll check.
⇡ # Appearance
Looks ASUS PA279 strictly and tidy – at first glance it is clear that this is not just one of hundreds of conventional monitors, but a real working tool. Even the red bar at the bottom of the display does not violate the serious kind ASUS PA279, but rather underlines it.
professional use monitor displays range in increments of 1 cm, located along the edges of the screen. OSD is activated with adjustable grid cell size – centimeters or inches. You can also display images on top of the frame corresponding to the physical size of standard documents and photos – A4, Letter, 4×6, 3×5 and so on.
The main body of the monitor is not a drop of gloss, and the assembly of any of claims is not. Monitor collected qualitatively, and all mechanisms are working smoothly stand – raise, lower the screen or rotate it 90 degrees, you can, without putting much effort. In all of this monitor will stand firmly on the table thanks to its broad base, and its screen will not wobble at any careless touch. In addition, the monitor was attached to a stand still at the factory, so it is not required to collect. If you want to fasten the monitor to another stand or bracket, you can unscrew the complete leg and use the mount VESA 100×100. At the same time can be chained to a nearby monitor large heavy piece of iron with a lock Kensington – unless, of course, have a desire or need.
Another important feature of the monitor-for-work, professional displays – it controls. In such devices, they try to make as simple and convenient for the owner, since it implies that in the menu of the monitor will have to go more often than usual in the monitor menu. Perhaps that is why the ASUS installed in the lower right corner of the screen a small five-way joystick – perhaps this is the best option for navigating the OSD. All other keys ASUS PA279 mechanical, no sensors (including a light sensor or presence) is not here.
On the left side ASUS PA279 are three ports USB 3.0, and a slot for memory cards (“nine to one”). But on the right side there is nothing interesting.
Often the reverse side of the monitor is not remarkable, but in the case of ASUS PA279 on it is worth paying attention to. At the point where the leg is connected to the housing of the display, there are round, but not numbered degree scale. Thanks to it, you can turn the monitor to the desired angle. Although in practice often have to rotate it 90 degrees. The same scale and have to supply the display – for the convenience of turning ASUS PA279 to the desired angle in the horizontal plane.
All ports and connectors are positioned perpendicular to the screen and directed downwards. Alas, the headphone jack is located “in the common heap”, although in our view, it would be much better if it is placed on the left side of the monitor, along with a card reader and ports USB.
Tilt screen can be in the range of -5 to 20 degrees and rotate – 60 degrees to the left or right.
As we wrote above, complete with monitor has a plastic visor, designed to protect against glare and excessive light. Apparently, ASUS thus want to emphasize professional direction, because such accessory is found in sets only the most expensive displays. Visor attached to the body of the monitor by using double-sided tape. Scotch already glued at the factory, so the entire installation procedure takes no more than a few minutes.
The right side of the visor has a sliding panel – it is needed in order to get easy access to the keys monitor control. Especially strongly it is useful if you have to use the joystick. And they, as shown, will have use for any action.
Also, in the upper part of the visor has a closed hole, which is useful when calibrating the monitor. Through it, you can stick a colorimeter or spectrophotometer cable.
⇡ # monitor menu
For those who have already had to deal with monitors ASUS, the appearance of the OSD will not be a revelation. It remains as simple and concise as before.
In the first tab, you can select one of the modes of operation of the monitor. Also here you can reset any mode to those installed by default.
In the next menu item contains all the other picture settings. In our case, part of the setup was not available – to twist them all, will have to choose one of two user profiles. Well, if you do not deal with the settings you want, you can include one of the predefined profiles: Standard, sRGB, Adobe RGB, as well as “theater” and “landscape”. The last two profiles listed – as it always does – show a very strange picture on the fan.
The other menu items are the same as that of the mass of the other monitors. Here you can enable the PIP (“PIP”) or PBP (picture from two sources side by side), find information about connecting, and if necessary, turn off the white light of the monitor.
If you noticed a mistake – select it with the mouse and press CTRL + ENTER.
