Introducing EIZO "4K displays" that meet the needs of high-definition and large screens
Full HD LCDs, which used to be high-end, have come down in price significantly over the past few years. 23-inch full HD models have now become mainstream in the domestic market. Since the shift to digital terrestrial broadcasting in 2011, the shift to full HD displays has accelerated, and although there was a feeling that the evolution after that had been stagnant for a while, the “next wave” has finally arrived. That is, of course, the rise of “4K displays”.
"4K" refers to a resolution of around 4000 pixels in the horizontal direction. "K" means kilo (1000). At present, most 4K displays are 3840 x 2160 pixels (4K UHDTV), which is four times the number of pixels compared to full HD 1920 x 1080 pixels. Separately, 4096×2160 pixels (DCI 4K) for movies is also called 4K.
Two types of "4K"
・3840×2160 pixels (4K UHD)
4K UHD is 4K defined by the ITU (International Telecommunications Union). The resolution is double the height and width of full HD, and is used in the TV industry.
・4096×2160 pixels (DCI 4K)
DCI 4K is 4K defined by DCI (an organization of film production companies). Higher horizontal resolution than 4K UHD. This resolution is double the height and width of the 2048 x 1080 pixels used in movie projectors and is used in the film industry.
In recent years, against the backdrop of high-resolution photos of digital cameras, high-resolution content such as 4K-compatible home video cameras, and high-definition displays installed in smartphones and tablets, displays for PCs are about full HD. I'm starting to run out of things. On the other hand, in order to improve the efficiency of multitasking, which is indispensable for PCs, attention is also increasing for large screens and multi-screens that can expand the work space.
In the midst of this, EIZO launched the new display "FlexScan EV3237". It is the company's first general-purpose display product that supports 4K resolution of 3840 x 2160 pixels, and is a flagship model with a large screen of 31.5 inches wide (visible area diagonal 79.9 cm). It is a high-end display for a new era that meets the two needs of "high definition" and "work space" with the highest specifications.
EIZO's 31.5-inch "4K" display "FlexScan EV3237"However, there are those who think that 4K has just started coming out, so it's still too early to buy. Not a few. So, this time, I would like to introduce you to the problems and problems that are common in recent display environments, and how the 4K display FlexScan EV3237 can solve them in a Q&A format. You should be able to understand that the FlexScan EV3237 is a display that you should consider as a purchase candidate now.
Eizo's "4K" smartly solves common problems with displays!
Q Once you get used to the high-definition display of your smartphone, tablet, or mobile PC, the external display screen will look rough and untidy. What can I do?
A The precision of the display display is expressed in words such as "pixel density" and "definition", and the degree is expressed numerically as "~ppi". ppi is an abbreviation for pixels per inch, which indicates the number of pixels per inch. If the distance between pixels (pixel pitch) is shortened while the screen size of the liquid crystal panel remains the same, the ppi will increase, and the higher this number, the higher the definition of the display.
The pixel density of smartphones is increasing at a tremendous rate, and currently many smartphones have a pixel density of 300ppi or more. This is a smooth display at a level where grains of pixels and jagged diagonal lines cannot be seen even if you bring your eyes close to the screen. There are also high-end terminals with overspecs that exceed 500ppi.
On the other hand, PC displays are mainly products with a pixel density of about 96ppi, in line with the display density of 96dpi (dot per inch), which has been the standard for Windows desktop UIs for generations. Modern UI such as the new start screen of Windows 8 and later uses 135dpi as the standard (automatically switches to 100%, 140%, and 180% depending on the pixel density of the display device), but the standard for desktop UI inherits 96dpi. ing. It is not surprising that the display looks rough compared to smartphones.
Difference in appearance due to pixel density. The upper image is an enlarged display of a small 10pt font, and the lower image is an enlarged display of a photo thumbnail. At 96ppi, the pixel roughness is noticeable, but at 192ppi it is greatly improved, and at 384ppi it becomes smooth so that grains of pixels and jagged diagonal lines cannot be seen. The display density (dpi) of the display has become variable, and it is now possible to smoothly enlarge the display by scaling according to the pixel density of the display. The Windows OS has been designed to allow the display density to be changed since the days of Windows XP, but it was after Windows 7 that it evolved to be usable at a practical level without greatly disrupting the screen layout.On Windows 8.1 or later, when multiple displays are connected, different display density settings can be applied to each display, reducing discomfort in a multi-screen environment where displays with different pixel densities are mixed (however, , the combination of display densities cannot be customized in detail, and the number of setting steps is limited).
Mac OS X also adopts a design that allows variable display density for high-definition displays (Apple calls them Retina displays) that were introduced ahead of Windows, and since OS X Mavericks 10.9.3, external displays It also supports changing the display density in .
Support for a high pixel density display environment in such a PC OS is said to support "HiDPI". Along with the support on the OS side, the support on the application side has progressed, and the PC environment surrounding HiDPI has reached a practical level, so PC displays with high pixel density are increasing.
This FlexScan EV3237 is one such product, and as an external large-screen display, it has a high-definition pixel density of approximately 140ppi. Although it is considerably lower than the pixel density of smartphones mentioned above, it should be noted that the distance used by smartphones and PC displays is significantly different.
In the case of the 31.5-inch display FlexScan EV3237, it is used from a distance of about 50 to 60 cm, so the display is as smooth as a smartphone. Moreover, the display size is much larger than that of a smartphone, so the amount of information that can be obtained at once is inconsistent. You can enjoy both photos and videos with overwhelming force.
The FlexScan EV3237, a 31.5-inch display, is farther from the viewing distance than smartphones, tablets, and notebook PCs, so even with a pixel density of about 140ppi, you can enjoy a smooth and high-definition display. It's hard to tell from a photo, but the 31.5-inch wide screen with a diagonal of about 80 centimeters displays detailed 4K resolution images, which is an impressive experience that you can't experience with a full HD class display.Q I want to improve work efficiency, but multi-display is difficult due to the installation space. I'm also curious about the frame that connects between the screens. Can't you improve work efficiency with one screen?
A There are roughly two possible patterns for an environment where multiple displays are arranged side by side. One is the case where multiple displays are connected in order to secure a large working space with one PC. The other is a case of displaying information from multiple PCs and working in parallel.
With the FlexScan EV3237, it is possible to operate for both purposes. First of all, in the former case, a large working area can be secured with a 4K resolution 31.5-inch wide liquid crystal panel (however, it is necessary to consider the enlarged display due to scaling. Details will be described later).
In the latter case, a total of 4 video inputs (DisplayPort x 2, HDMI x 1, DVI-D 24 pin x 1) and PbyP (Picture by Picture) and PinP (Picture) that can display multiple video signals simultaneously in Picture) functions are effective.
Input terminal of "FlexScan EV3237". DVI-D, HDMI, DisplayPort 1.2 × 2 from the left. To the right of it is the USB 3.0 hub function up port, line input. It also has a built-in power supply unit and a main power switch that cuts power consumption when not in use. In addition, the left side has a USB 3.0 hub function down port x 3 and a headphone outputIf you use the PbyP function, you can display images from multiple sources side by side on a large screen. It is possible. PbyP has a wide variety of display modes, split horizontally (2 screens of 3840 x 1080 pixels), split vertically (2 screens of 1920 x 2160 pixels), and divide the left half (or right half) horizontally. It supports display such as splitting into 2 (1920 x 2160 pixels + 2 full HD screens) and splitting vertically and horizontally into 4 (4 full HD screens).
In any setting, there is no dividing line between screens, and it is easy to use because it can display a completely frameless multi-display. By the way, the 4-screen display is similar to arranging four full HD displays of about 15 to 16 inches without gaps.
With the PbyP function, video signals from multiple PCs can be displayed side by side on one screen at the same time. You can choose from 5 different layouts. It is also expected to be used like a digital signage that simultaneously displays videos, advertisements, information, etc.An example of displaying three video signals side by side using the PbyP function. The left half is 1920 x 2160 pixels, and the top right and bottom right are each 1920 x 1080 pixels. Taking advantage of the 31.5-inch large screen and 4K high-definition, multi-display display without frames between screensOn the other hand, if you don't mind displaying on a small child screen, you can use the PinP function. By using it, you can "work while" while making the most of the large display area. The size of the child screen can be selected from two sizes, and the placement can be set to the four corners.
A PinP function is also provided, and small screens can be superimposed and displayed. While day-trading on the main screen, you can also play the streaming video of the general meeting of shareholders on the sub-screen. The child screen is smaller than the minimum size of PbyP, and the main screen can be used widely, so it is suitable for applications such as working while playing videosQ Full HD or WUXGA for editing high-pixel photos and videos That's not enough. Is WQHD or Ultra Wide (Cinesco) OK? "Or should I choose 4K now?" 1|2|3Next page
