ASUS PA248Q professional display first test
ASUS PA series has been committed to the field of professional services, to meet the professional photographers, professional video studios, professional graphic designers and so on the field of daily use requirements .In early this year, ASUS launched a new PA Series LCD, 24-inch widescreen, it is also located in a professional LCD display.
ASUS PA248Q not only uses a professional-grade IPS panel, also has LED backlight, 16:10 screen ratio, and design, and can support the fuselage lifting and rotating functions, almost meet the professional-level display in the user regulation and functional requirements In the interface, in addition to the traditional D-Sub, DVI-D interface, the ASUS PA248Q also provides HDMI, Displayport and multiple USB 3.0 interface, to meet the needs of the user connection.
In addition, the ASUS PA248Q allows the user to preview the image file with the exclusive 'QuickFit One Button Layout' function. The QuickFit function supports analog preview A4 paper, letter, 8 × 10 ', 5 × 7', 4 × 6 ', 3 ASUS PA248Q also has a 5-way navigation key, you can also customize the two shortcut function hotkeys, set the commonly used 10 OSD functions with support PIP (picture-in-picture ) And PBP (multi-screen display) function, allowing users to switch between video and audio.
According to ASUS officials, each ASUS PA248Q has been set in the factory before the optimization of color accuracy, the maximum degree of relief Delta E color difference. At the same time, the product can be a separate red, green, blue, cyan, orange And yellow for hue saturation adjustment.
Now, ASUS PA248Q LCD monitor has come to the ZOL monitor channel evaluation room, today let us use professional equipment to test, through the professional data and our explanation to show this professional display to combat the display capabilities.
Professional IPS color reproduction ability?
First of all, we passed the Spyder Elite 3 color instrument to test the accuracy of ASUS color reproduction.This indicator industry to use ΔE value to reflect, Δ E can restore the accuracy of color quantization as a value, it can accurately reflect the performance of the color accuracy.
Spyder Elite 3 Colormeter
Note: ΔE value reflects the difference between the display and the standard value of the size, so the smaller the value the better, the higher the score that the more color distortion.
The figure is ASUS PA248Q the performance of various colors on the accuracy of that, the left side of the picture on behalf of the right side of the rectangular box represents the color of the ΔE value, the smaller the value of its performance on the color of the more accurate. Test, ASUS PA248Q on these 23 colors The average ΔE value was 2.81 and the maximum value was 6.73, To a very good standard.
We can see from the figure, ASUS PA248Q for most of the color reduction ability are more accurate, ΔE values are below 3. But for some green, blue, brown and other color reduction ability is more general, ΔE value of 5 or more .
● ΔE value interpretation
ΔE value between 1.6 to 3.2, the human eye is basically not distinguish the color difference, where only a few professional-grade displays, such as the value of million EIZO, NEC 2690WUXi and other models can do;
Between 3.2 and 6.5, professionally trained people can distinguish the difference, but ordinary people are not observed in the difference, usually professional-grade LCD to achieve this standard, and a few excellent consumer-level LCD can also enter the interval ;
Between 6.5 and 13, the color difference can be determined, but the color itself is still the same. At this point the majority of consumer-level LCD display on the market in this grade;
In 13 to 25, you can determine the performance of different tones, but also identify the color of the subordinate;
More than 25 or more, on behalf of the other is a color.
PA248Q color display how?
Next, we come through the professional instrument to carry on the test to the ASUS color characteristic.In the test before we let ASUS PA248Q normal continuous use for more than an hour, and close the dynamic contrast function and all color enhancement technology.This test environment color In this test, our test environment light source color temperature 5000K, illumination 53Lux, fully in line with the standard.
Spyder Elite 3 Colors
Next, we have to do is to use the Spyder Elite 3 school colorimeter to produce this model of the original icc file, and its analysis of the color characteristics of ASUS PA248Q performance. The white closed curve in the picture below represents the sRGB color space, and the red closed curve represents the ASUS PA248Q color space.
In the above figure, theoretically, the red area if fully cover the white sRGB color space is the most ideal.Through the above picture, we can see on behalf of the ASUS PA248Q color space basically covers the entire sRGB color space , It is for the vast majority of colors can be very rich performance, only a small part of the color display performance is slightly inadequate.Overall, its performance is very good.
●The meaning of the sRGB color space is covered
The sRGB color space is a standard RGB color space developed by HP and Microsoft for use with the Internet, which defines the colors of the red, green, and blue primary colors, that is, when the other two color values are zero So if the monitor can fully contain sRGB color gamut, it can fully qualified for ordinary photography and print work, color display will be more accurate, and does not appear can not display the color, and if the monitor can not fully cover the sRGB color space, Note This monitor may not display some colors properly. For more details, see "".
Screen brightness uniformity performance right?
Next, we on the Asus screen uniformity test, the first screen brightness uniformity test.The screen brightness uniformity of the same test with the Spyder 3 Elite colorimeter to complete the screen, we will be divided into nine large areas of the screen, The distribution test calculates the screen's brightness at full white, black, and chromaticity coordinates, and finally draws the following conclusions (the following results are 100% IRE output, which is tested with maximum brightness and contrast output)
ASUS PA248Q brightness data in nine regions and the difference with the brightness of the center point
(The smaller the difference, the more uniform)
If the above figure boring data so that you can not on the ASUS PA248Q a more detailed understanding, then we can through the following screen brightness distribution to observe.
Through the above figure, we can see the ASUS PA248Q screen center is the highest brightness, the value of 286.9d / m2, and its upper right corner of the screen brightness is relatively low, about 14% lower than the highest point.In addition, ASUS PA248Q display screen Overall, the brightness of the central part of the screen is higher than the corner part of the uniformity of performance in the upper level.
Color temperature consistency and gamma curve optimization
●ASUS Color Temperature Consistency Test
The purpose of this test is to test the stability of the color temperature of the white point under different brightness, after all, the user will adjust the brightness of the display at any time, at this time the contrast and color temperature is not the same. Should be too much change.We will adjust the ASUS PA248Q screen brightness to 0, 25, 50, 75 and 100, test brightness and full black when the brightness and chromaticity coordinates to calculate the contrast and color temperature value.Under each brightness The color temperature value and the contrast ratio does not change is the most ideal.
ASUS PA248Q LCD color temperature consistency test
In the color temperature consistency, you can see the performance of ASUS PA248Q is not very stable, roughly 6500K to 6700K, we test the standard value of 6500K, so ASUS PA248Q in low brightness, the color is very accurate.In the high brightness, color slightly Partial cold.
●ASUS PA248Q liquid crystal display gamma curve optimization
Finally, we take a look at ASUS PA248Q LCD monitor how to optimize the performance of the gamma curve.
