After smartphones replaced personal computers as the most commonly used Internet devices for mainstream users, the entertainment attributes and professional office attributes of desktop computers have been elevated. Both of these requirements have large requirements for the size of the display, and they are pursued in entertainment. The sensory stimulation brought by the large screen; the pursuit of multitasking efficiency with large size in office.
Therefore, the mainstream display sizes in recent years have also been quietly changing, and there is now a trend of development from 27 inches to larger sizes. And what we want to understand today is a very representative 40-inch led monitor --- Hopestar 40A2 40 INCH 4K Gaming Monitor.
Performance: AMD IPS panel
It comes with a 40-inch IPS panel, which supports the maximum 144hz refresh rate and 3440 ×1440(4K) resolution.
Officially, it is said that the typical brightness is 350 nits, the peak brightness is 400 nits, the contrast can reach 1200:1, and supports the color display output of up to 8bit.
The gamut coverage of 99% sRGB, 89% Adobe RGB and 89% dci-p3 were measured in the display cal. This performance is good in such a large screen and IPS LED monitor, especially sRGB with almost 100% coverage can meet most of the needs of daily entertainment and office in the mainstream windows system.
In terms of color standards, 40A2 performed well in 48 color tests, with an average value of delta e 1.23. The maximum value is delta e 4.68; The minimum value is delta e 0.11. It can be seen that MICROSTAR's color adjustment for this panel is quite good, so that it can restore the display content more accurately and let users feel a more real color display.
In terms of movie viewing, the visual enjoyment brought by the large screen is more obvious. Whether it is the immersion of the picture or color details, 40A2 can bring a flagship feeling. 4K resolution makes the HD native film source no longer limited by resolution, and the display is more delicate and realistic.
Practical experience: IMAX giant screen on the desktop
In the actual experience, the 40 inch 21:9 IPS screen can play a better visual experience in entertainment and office. For example, in the game, the screen content will be much wider than the traditional 16:9 display, which can better find the enemy and observe the surroundings. In addition, the g-sync technology of 40A2 and the game auxiliary collimation make the overall picture of the game more smooth, and the aiming and shooting more convenient and accurate.
