●Acer XB280HK Feature introduction:
28-inch ultra-large display screen, with high-definition UHD, 3840*2160 @60Hz resolution. UHD extreme high-definition display can provide 4 times full HD pictures. Full HD (1080P)
NVIDIA G-SYNC technology can ensure that every frame of the GPU can be displayed perfectly. Its revolutionary picture performance is achieved by synchronizing the display's comfort rate with the GPU refresh frequency powered by GEFORCE GTX. G-SYNC can even eliminate screen tear when the user starts the gaming experience and minimizes the card frame and input delay of the display.
Through the ultimate motion gelatinization technology (ULMB), the stage in motion can be perfectly clear and there is no visual gelatinization effect to be displayed. ULMB technology refreshes each pixel when the display backlight is turned off. Once all pixels have been updated to the latest value, the backlight will light up for a short time. If this is done at very high frequencies, you won't see any screen flashing.
1ms (grayscale) Quick response time can enhance the player's in-game experience. No matter how fast the movement is or how intense the transmission is, the ACER gaming monitor can provide a smooth picture without any interference.
Although the screen flickering is not noticeable, it will increase the burden on the eyes and even damage your vision health. ACER non-splash display eliminates annoying screen flickering, thus providing a more comfortable visual experience.

Admiral XB280HK monitor appearance and details appreciation:
As a gaming monitor positioning professional players, Acer XB280HK uses a 28-inch matte screen, and the stylish and atmospheric appearance design presents a professional atmosphere.
On the back of the monitor, the Acer XB280HK is made of matte plastic, which feels comfortable and fine and durable, and the "acer" in the upper right corner is particularly conspicuous. What is more eye-catching is the red embellishment on the base, which makes the overall display look less dull. The round base is not light in weight, providing good guarantee for the stability of the 28-inch large-screen monitor.
XB280HK display details
The overall border of the monitor is still relatively narrow, providing players with a broader field of view.
This monitor uses physical OSD keys. When adjusting the menu, the screen will have a function corresponding to the key position, making the display more simple appearance.
video interface only uses one Displayport 1.2 interface, which is related to 4K resolution and G-Sync function. Currently, only DisplayPort interface has an input standard that can drive 4K displays with sufficient bandwidth, so it is reasonable to cancel other video input interfaces.
This monitor is also equipped with 4 USB 4.0 ports, and 2 are provided on the side and back of the body, which can be used as a USB hub.
monitor ergonomics is more common on high-end monitors and can provide a more comfortable viewing experience. This monitor offers 150mm height adjustment, which lowers the display to desktop height.
XB280HK monitor supports vertical rotation of the screen 90°, and can provide vertical display of the monitor, providing convenience for browsing web pages and vertical screen games.
Acer XB280HK monitor tilt angle is -5° to 35°, and the base supports rotation around 120°. Users can get the best viewing angle of the monitor at any angle without moving the monitor.
Since this monitor supports 4K resolution and supports special gaming technologies such as G-SYNC and NVIDIA-ULMB. Then you must experience gaming at 4K resolution on this "4K+G-SYNC" monitor.
has the resolution of this monitor that can reach 3840*2160 and can provide a refresh rate of 60Hz. A 60Hz refresh rate is not uncommon for general monitors, but due to the resolution limitations of 4K monitors, monitors that can maintain a 60Hz refresh rate are already at the top level.
K resolution display effect experience:
In the video playback experience of 4K film sources, the 4K ultra-high resolution of Acer XB280HK is ultimately reflected. Whether you look from a distance or close up, you can detect the presentation of each pixel on the screen, and the screen display effect is very delicate and realistic.
K resolution gaming experience:
NVIDIA control panel
Under hardware configuration conditions such as graphics card, connect to Acer XB2810HK to enable the G-SYNC function in the NVIDIA control panel. Make sure to test with G-SYNC turned on.
's latest large-scale games basically support 4K output. The game screen at 4K resolution is much more realistic than 1080P, and the details can be presented perfectly, and the fine picture is comparable to the cinema picture quality. In addition, this Acer XB280HK monitor also has an extremely fast response speed of 1ms, and the fast screen can be presented smoothly without any smear or blur.
G-SYNC is NVIDIA's new technology for picture coherence. It can make the screen fully synchronize with the GPU no matter how fast the picture update rate is. G-SYNC technology not only solves the problem of picture tearing, but also fundamentally solves the problem of picture visual lag that has plagued vertical synchronization technology for a long time.
Open G-SYNC's Acer XB2810HK, which is visually smooth in the game screen, saying goodbye to the scene tear, shadowing and other phenomena.Since the smoothness of the picture is not reflected in everyone's photos, but during the actual test, after turning on G-SYNC, the smoothness of the game screen is greatly improved, which has a certain effect on improving the game experience.

NVIDIA-ULMB function is to sharpen one-click for high-speed sports game screens to solve the phenomenon of fuzzy and smos. After turning on ULMB mode in the menu, the most intuitive change is that the brightness is reduced a lot. However, through actual experience, we can find obvious changes, the objects in the bright spots are clearer, the contrast is higher, and the picture is sharper.
Smooth 4K gaming experience has a high demand for graphics cards:
Although the current high-end games support 4K resolution, a smooth 4K gaming experience will test the players' computer hardware configuration. Let's use the GTX980 monitor to test it to see how the performance of graphics cards is at the 4K resolution of mainstream games?
Judging from the above test results, high-end graphics cards seem to be very difficult to deal with 4K resolution. For example, "Crisis 3" has only a frame rate of 17, so it is basically impossible to play. It can be seen that 4K has a very high demand for hardware, and ordinary players can only sigh.
●Grayscale test
Grayscale refers to the brightness hierarchy relationship between the darkest black to the brightest white of the monitor. The clearer the image, the more natural the transition, the better. On the gray scale, the performance of 32-level gray scale and 256-level gray scale are mainly used for testing.
32 Grade Gray Level (the more grids can be displayed, the better)
Monitor 32 Gray Level Performance: Poor Poor Medium Good Excellent
256 Gray Level (the more grids can be displayed, the better)
Monitor 256 Gray Level Performance: Poor Poor Medium Good Excellent
Acer XB280HK monitor uses TN panel, which makes the real shots look better in grayscale comparison. It can be seen from the 256-level gray scale that most squares can be clearly identified, with a wide range of excessiveness and a high black and white contrast.
●Color Saturation Test
In terms of color saturation, the brighter the picture displayed on the monitor, the more transparent it is, and the smoother the transition, the better the performance, and vice versa.
Color saturation (the more colorful the color, the better the transparent the better)
Monitor color saturation performance: poor, poor, medium, good, excellent,
The picture above shows that the color transition of this monitor is relatively smooth, the color saturation is good, and the overall color performance is good.
●Backlight test
On the backlight, the display effect of the display pure white picture and the real-time picture display image adjustment threshold effect screenshots are mainly used to display.
pure white picture display (the more uniform the color, the better)
backlight distribution performance: poor, poor, medium, good, , excellent,
28-inch large screen backlight distribution is also quite uniform, and no obvious dark parts are found.
light leakage test (pure black display real shot)
light leakage: Excellent light leakage control
pure black picture real shot, it is difficult to find light leakage, and has excellent light leakage control capabilities.
●Picture restoration effect comparison test
The following chart is the comparison picture between the real photo and the original picture. From this, we can basically see how the color restoration effect of a monitor is.
Note: Due to the camera shooting, the obtained real photos will suffer some losses, and due to different cameras, the style of the obtained pictures will also be different. This is for basic reference only. The color display of the screen made of
TN is obviously not as bright as that of the IPS screen. From the comparison picture of the color restoration effect of the picture above, it can be seen that the three primary colors are restored in a relatively average way. The red color is yellow, and the blue color is slightly purple. The color accuracy is weak. In the colorful real photos, the red color reproduction and yellowing imagination is more obvious. High contrast. In the renderings of the characters, the skin color is restored well and the overall performance is good.
●Acer XB280HK visual angle measured
Acer XB280HK visual angle is good, and there is no obvious brightness attenuation in the left and right viewing angles. However, there is a serious color deviation at the upper and lower angles. The character's color is white when viewed from the bottom, and the color distortion of the picture at the bottom is serious. The pursuit of the game's high responsiveness and adopting the TN screen has made some sacrifices and compromises in the visual angle. However, the Acer XB280HK monitor uses an ergonomic bracket to solve the problem of insufficient visual angle, allowing users to obtain the best screen display effect under any circumstances.
● Acer XB280HK brightness|contrast|color gamut|color temperature|color accuracy|brightness uniformity
Below are objective data about this monitor tested through the Aiseli i1 Publish Pro2 professional monitor screen color correction instrument.

| NTSC color gamut | 72% | 77.6% | 5.6% | ||
| color temperature | 6500K | 6582K | color temperature standard |
After testing, it was found that the center of the display was 233 cd/㎡ basically meets users' needs for brightness in various daily use. The black level is 0.357cd/m2 and the static contrast is 652:1. The NTSC color gamut of the monitor is higher than the standard 72%, making it a wider color gamut. The color temperature of 6582K is quite standard and the display effect is quite comfortable.
●Brightness uniformity test
After the brightness uniformity test, it was found that the center of the display was the highest brightness, 233cd/m² and the lowest was 181cd/m², with a brightness difference of 22%. The brightness distribution uniformity of the Acer XB280HK monitor needs to be improved. The color temperature is relatively uniform, with a small difference from the standard color temperature, and excellent color temperature uniformity.
●Color accuracy test
In terms of color accuracy, ΔE value is regarded as a key indicator for measuring the quality of a product. The closer ΔE is to 1, the more accurate the color is. The average ΔE of this touch monitor is only 1.07, which meets the standards of professional monitors and has a very high overall color accuracy. Only some colors have the maximum ΔE of 7.50, and some colors need to be restored.
When △E≤1, the human eye can hardly distinguish the difference between the two colors;
When 1△E3, the human eye needs to compare the difference between the subtle color differences;
When △E5, the human eye can distinguish the difference between the colors and think it is two similar colors.
When △E5, most human eyes can see the color difference and think it is a completely different color.
