More and more personal computers are being outfitted with high-definition (4K) displays. Even if it sounds like science fiction, these displays tackle a variety of display issues and provide the greatest possible viewing experience. Particularly when considering display options in the long term, the FlexScan EV3237 from EIZO is a key competitor.

Enlarge your viewing experience with a high-definition 4K display from EIZO.

Full HD liquid crystal displays used to be considered high-end, but prices have dropped significantly in recent years, and today 23″ full HD devices have entered the domestic market and are now mainstream. The adoption of full HD monitors accelerated around the time of the switch to terrestrial digital broadcasting. The next wave has finally arrived, despite the sense of stasis following it. No surprise here: 4K TVs are to thank for this.

Horizontal resolutions of roughly 4,000 pixels are referred to as “4K.” K is the abbreviation for “kilo” (thousand). 3840 x 2160 pixel (4K UHDTV) resolution is the standard for most of today’s 4K displays, which is exactly four times the pixel count of full HD displays (1920 x 1080 pixels). The film industry uses 4096 x 2160 pixel (DCI 4K) screens, which are also referred to as 4K displays, as well.

Two types of 4K


3840 x 2160 pixels (4K UHD)

4K UHD is 4K as defined by the ITU (International Telecommunication Union). It has twice the horizontal and vertical resolution of full HD and has been adopted by the television industry.


4096 x 2160 pixels (DCI 4K)

DCI 4K is 4K as defined by DCI (Digital Cinema Initiatives). The horizontal resolution is higher than 4K UHD. This resolution is twice the horizontal and vertical resolution of projectors (2048 x 1080 pixels) and has been adopted by the film industry.

Full HD screens on PCs are getting less and less appealing in the face of ever-increasing digital camera photograph resolutions, ever-increasing content of home video cameras enabling 4K, and other such advances. As a result, interest is growing in wide screens and multi-screen setups that provide greater work areas to boost the efficiency of multi-tasking, which is vital for PCs.

This was the backdrop to EIZO’s much-anticipated new FlexScan EV3237 display. The first of its universal displays to enable 4K resolution of 3840 x 2160 pixels is this new flagship model with a big 31.5″ wide screen (visible diagonal size: 79.9 cm). With top-tier features, it’s a high-end display for the modern day that satisfies the twin demands of high definition and a big work area.

FlexScan EV3237

EIZO’s 31.5″ FlexScan EV3237 4K display

Having said that, there are certainly a lot of people out there who are curious about whether or not it is still too soon to get a 4K monitor. In this post, we’ll look at how the FlexScan EV3237 4K display can help solve problems and concerns that have become more common in display environments recently using a question and answer style. We are confident that you will come to the conclusion that the FlexScan EV3237 ought to be one of the potential acquisitions that you have on your list right this minute.

The EIZO 4K display is an intelligent solution to many of the typical problems regarding screens!

My eyes have become accustomed to the high-definition display on my smartphone, tablet, or laptop. As a result, the screen on my external display appears pixelated and lifeless to me. Is there no other way to explain it?

The level of detail that may be seen on displays is described in terms of the pixel density or definition, and the ppi unit is used to provide a numerical representation of that degree. “Pixels per inch” is what “ppi” stands for. The number of pixels per inch (ppi) can be increased without increasing the screen size of the LCD panel by decreasing the spacing between individual pixels, also known as the pixel pitch. The higher the number, the more detailed the display will be.

Many of today’s smartphones have pixel densities of 300 ppi or higher, and the rate at which pixel density is improving on smartphones is accelerating at a breakneck pace. Even if you look very carefully at the screen, you will not be able to make out any pixel grains or jagged diagonal lines since the display is so smooth. There are also some high-end gadgets that have a pixel density that is more than 500 ppi, which is virtually an overkill.

When it comes to personal computer displays, the majority of devices have a pixel density of approximately 96 ppi, which is designed to match the display density of 96 dpi (dots per inch), which is the standard for the Windows desktop user interface. The standard for the desktop user interface is still 96 dots per inch, whereas the standard for the new Start screen and other aspects of the Modern UI in Windows 8 and later versions of the operating system is 135 dots per inch (and will automatically switch between 100 percent, 140 percent, and 180 percent depending on the pixel density of the display device). Therefore, it should not come as a surprise that the display is not as smooth as those seen on smartphones.


Pixel density


Differences in appearance can be attributed to the varying density of individual pixels. The image on top is an enlarged version of a font that is 10 points in size, while the image below is an enlarged version of a photograph’s thumbnail. The roughness of the pixels is visible when the resolution is 96 ppi, but the quality is significantly improved when it is 192 ppi. The image is grain-free and smooth at a resolution of 384 ppi; the jagged edges of diagonal lines and pixel grains are no longer discernible.

The display density (dpi) of PC operating systems, on the other hand, is now flexible, which means that scaling according to the pixel density of the display makes it feasible to perform seamless magnification. Altering the display density on a Windows operating system has been feasible ever since Windows XP; however, it wasn’t until Windows 7 that it became able to do it in a way that was both practical and did not dramatically disrupt the screen layout.

Since Windows 8.1, it has been possible to apply different display density settings to different displays when multiple displays are connected, and the feeling of incongruity that is experienced in a multi-screen environment with displays of different pixel densities has been reduced. This feature was introduced to address the shortcomings of previous versions of Windows (however, the number of setting levels is limited, so the combination of display densities cannot be elaborately customized).

Display density on high-definition displays can be adjusted using Mac OS X, which was one of the first operating systems to do so after Windows adopted the concept (referred to as “Retina displays” by Apple). This support for external monitors has been provided for OS X Mavericks since version 10.9.3 of the operating system.

The term “HiDPI support” refers to the capability of the PC operating system to accommodate displays with a high pixel density. The PC ecosystem that surrounds high-dpi displays has reached a level where it is practical, and the level of support for high-dpi displays among operating systems and applications is continuing to improve. As a direct result of this trend, high pixel density PC screens are becoming increasingly common.

One of these products is the FlexScan EV3237, which is a high-definition external display with a pixel density of approximately 140 ppi and is designed for use with large screens. This is a very low number in compared to the pixel density of smartphones, which was discussed earlier; however, it is important to keep in mind that the distance at which cellphones and PC displays are viewed is considerably different.

People use the 31.5″ FlexScan EV3237 from a distance of approximately 50-60 centimeters, which is why the display looks to be as smooth as that of smartphones. In addition, the display size is far greater than that of smartphones, making it possible to view a great deal more information at the same time. Also more impressive are moving pictures and still photographs.

Because the 31.5″ FlexScan EV3237 is viewed from a considerably larger distance than smartphones, tablets, and laptops, the display seems smooth and high-definition while having a pixel density of approximately 140 ppi. It is difficult to tell from images, but viewing a high-definition video with a resolution of 4K on a screen that is 31.5″ wide (about 80 centimeters diagonally from corner to corner) is an incredible experience that cannot be had with a display that just provides full HD resolution.

I would like to improve the efficiency of my work, but I do not have enough room for a system that includes many displays. Having a frame in the middle of the screens is another thing that bothers me. Is there a way that one screen can improve one’s ability to work more efficiently?

When it comes to settings that include many monitors that are lined up side by side, there are basically two patterns to consider. One is an arrangement in which many monitors are connected to a single personal computer in order to create additional room for working. The other is a location where information is shown simultaneously from a number of different personal computers.

The FlexScan EV3237 is versatile enough to serve either function. To begin, the 31.5″ wide LCD display with 4K resolution that is used in the first scenario provides a substantial area for working (however, magnification via scaling also has to be taken into account; more details are provided later).

In the latter scenario, image input from four different systems (DisplayPort x 2, HDMI x 1, and DVI-D 24-pin x 1) together with functionalities known as PbyP (Picture by Picture) and PinP (Picture in Picture), which can show multiple image signals at the same time, come into play.

Terminals for input on the FlexScan EV3237. DVI-D, HDMI, and two DisplayPort 1.2 connectors may be seen moving clockwise from left to right. These are the upstream port and line input for the USB 3.0 hub, and they are located to the right of these. There is a power supply unit that is built in, and it also comes with a main power switch so that power consumption can be reduced while the device is not being used. In addition to that, there is a headphone jack on the left side of the device, as well as three USB 3.0 downstream ports.

The picture-by-picture (PbyP) function allows for the images from a number of different sources to be presented on the large screen in a side-by-side fashion. PbyP is compatible with a wide variety of display modes, including splitting the screen horizontally (two 3840 x 1080 pixel screens), splitting the screen vertically (two 1920 x 2160 pixel screens), splitting the screen horizontally across the left (or right) half (1920 x 2160 pixel + two full HD screens), and splitting the screen both horizontally and vertically into four screens (four full HD screens).

Because there are never any lines dividing the screens with any of the settings, the multi-display configuration is totally frameless, which means that it is very simple to use. This makes it very convenient. A side note: having a four-screen display is about equivalent to having four 15-16-inch full-HD displays lined up next to each other with no space in between them.

With the help of the PbyP feature, visual signals from a number of different personal computers can be shown concurrently and side-by-side on a single screen. There are five different formats for you to select from. A simultaneous display of films, advertising, and other types of information may also be possible if it is implemented in a manner analogous to that of digital signage.

With the help of the PbyP feature, visual signals from a number of different personal computers can be shown concurrently and side-by-side on a single screen. There are five different formats for you to select from. A simultaneous display of films, advertising, and other types of information may also be possible if it is implemented in a manner analogous to that of digital signage.



The PbyP function allowed for the viewing of all three image signals simultaneously. The pixel dimensions of the left half are 1920 by 2160, whereas the pixel dimensions of the top and bottom of the right half are also 1920 by 1080. It is possible to construct a multi-display arrangement with no frames appearing between panels by taking advantage of the huge 31.5″ screen and the high definition 4K display.

On the other hand, if you only need a small sub-screen, you can use the picture-in-picture (PinP) function to perform parallel work while still making use of the extensive display surface. There are two different sizes of sub-screens available for your selection, and you are free to position them in any of the four corners.




It is also possible to overlay a small sub-screen on top of the main screen using the PinP function. Streaming video of a shareholder meeting might be played in a sub-screen while the main screen is used for day trading.

FlexScan EV2736W


The 27-inch FlexScan EV2736W wide LCD from EIZO. It has a WQHD resolution, which is 2560 by 1440 pixels with 109 pixels per inch. This model of the FlexScan EV series was the flagship model before the FlexScan EV3237 came out, however if you are only now beginning to look at different items, you should make sure that you take into consideration 4K screens.

I recently purchased a laptop with a display that has an extremely high pixel density; yet, unless I use scaling to magnify the image by 150–200 percent, it is not feasible to use. Shouldn’t a 4K monitor offer the same experience in the end?

As was noted before, nowadays, a growing number of laptops are being manufactured with high-definition LCD displays since HiDPI has reached a level where it is practically usable. With the idea that scaling will be utilized for magnification, these devices leverage high-definition displays as their selling point. This means that high resolution does not necessarily require a huge work space, as it did in the past when display density was supposed to be constant.

The distance at which a laptop is viewed is closer than it is with external displays, so pixel density is higher (about 220ppi on a 13.3″ 2560 x 1440 pixel display), which means that pixel pitch is that much shorter. This has a significant impact on both visibility and legibility (approx. 0.12mm). The text and icon display is too small when magnified to one hundred percent without any scaling applied.

In addition, as a result of the high-definition display, the pixel pitch on the FlexScan EV3237 is quite small. For instance, if you wanted to maintain the same pixel pitch (approximately 0.27mm) as a currently mainstream 23-inch full HD display with a 4K resolution display, you would need to double the screen size with a 46-inch display. This is because the size of the pixels in a 4K display is much smaller than the size of the pixels in a full HD display. Due to the fact that this is packed into a panel that is 31.5 inches in size, the pixel pitch is naturally more compact.

Having said that, the enormous screen size of 31.5″ means that it is not as exceedingly fine as it would be on a 4K display measuring either 23.8″ or 28″. Because the pixel pitch is around 0.18 mm, it is possible to use it without scaling if the installation position is chosen carefully and the viewing distance is adjusted appropriately. However, utilizing a large screen like a 31.5″ one up close puts additional strain on the eyes and neck, hence it is recommended that the scaling option be utilized in these situations.

Because the pixel pitch is not overly tiny, an excessive amount of magnification is not necessary. It’s very useable from approximately “Medium – 125 percent” and up, which means you can have both a high-definition display and a huge work space. The DPI Display Size settings may be found in the Windows control panel. You can set it to “Larger – 150 percent” if you want it to be approximately the same text size as a regular 23-inch full HD display (approximately 96 pixels per inch). This will cause the display to be approximately the same size.

The phrase “Smaller – 100 percent” can be found on the left, while “Medium – 125 percent” can be found on the right. Alterations are made to the dimensions of both the icon and the text.

The text “Larger – 150 percent” can be seen on the left, while “Extra Large – 200 percent” can be found on the right. The user interface of the Windows desktop is comparable to the industry standard of 96 dots per inch when scaled to 150%. (103 percent compared to the standard 96 dpi).

The display area is currently set to “100% smaller.” This is the standard magnification, and all 3840 by 2160 of the available pixels in the 4K resolution can be used effectively. The pixel density comes in at roughly 140 ppi, and the pixel pitch measures somewhere around 0.18mm. This setting is not completely unusable; nevertheless, it is easier to see the screen when it is set to “Medium – 125 percent” or “Larger – 150 percent.”

The display area has been changed to “Larger – 150 percent.” When scaling is employed to achieve a magnification of 150%, the amount of available workspace is reduced; however, both the text and the icons become significantly easier to read. If you want the user interface of the Windows desktop to be about 96 dpi, this is the best setting to use. This environment strikes a good balance between the work space and the definition.

On the left is the FlexScan EV3237, which has a screen size of 31.5 inches and a resolution of 3840 by 2160 pixels, and on the right is the FlexScan EV2436W-Z, which has a screen size of 24.1 inches and a resolution of 1920 by 1200 pixels. When the FlexScan EV3237 is set to a magnification level of 150%, the look of the text and icons is comparable to the appearance they have when seen on the FlexScan EV2436W-Z when the magnification level is set to 100%. You are able to maintain a sizable working area even when the magnification is increased to 150% by utilizing the full width of the 31.5″ display.

Although the viewing distance also plays a role, regular use becomes more difficult at normal magnification if the pixel pitch is any narrower than approximately 0.2 mm. As a result, the magnification must be increased using the scaling setting if the pixel pitch is any narrower than that.

Isn’t it more straining on the eyes and shoulders to look at really large-screen, high-definition displays?


When working on a computer, it is vital to be attentive of a number of different factors in order to reduce the strain that is caused on the eyes, neck, and shoulders. Displays must meet a minimal set of requirements, including having a non-glare LCD panel surface to reduce the amount of reflection and having the ability to alter the brightness, height, and angle of the display.

Large-screen, high-definition display situations, in general, have a tendency to create stress on the eyes and shoulders; nevertheless, the FlexScan EV3237 includes numerous features that decrease the stress that is caused by these surroundings. Users of EIZO products are already familiar with the FlexStand, which boasts a wide range of motion and allows the user to tilt, rotate, and modify the height of the monitor. The high level of adjustability combined with the fluid motion ensures that it is suitable for every application setting.

The same may be said about adjusting the level of brightness. It begins with a very dark display so that it can be adjusted to match the level of brightness present in the surrounding environment. Nevertheless, the “Auto EcoView” function is by far the most useful. The display’s brightness is automatically adjusted to the ideal level by an illuminance sensor that is embedded right into the device. This means that the user does not have to worry about adjusting the display’s brightness even if they are in an environment where the level of illumination varies.

Because it also has a number of other features, such as “Paper Mode,” which significantly lessens the amount of blue light, and “EyeCare Dimming,” which controls the flickering caused by the LED backlight, a significant benefit is that it is possible to reduce the strain on the eyes without the user having to make any conscious efforts to do so.


Height adjustable


The height is highly adjustable, and the screen can be lowered just above the installation surface, so even the large models can be set up so that you naturally look down at the display.


Auto EcoView


Auto EcoView is a great way to conserve electricity while also providing some much-needed respite for your tired eyes. The OSD menu can be accessed by pressing the button on the LCD’s front panel (left). For the first time, customers will be able to set the maximum and lowest values for automatic brightness adjustment in this new model (right).

As soon as the button is hit on the front, the menu is shown straight above, making it simple to operate. Other from the power button, no indications are displayed in this menu.

I’m looking for a long-lasting, high-quality display that I can rely on for a long time. What’s the best option for me?

It’s understandable that you’d want to invest in a long-lasting, dependable large-screen monitor in this price range. The FlexScan EV3237 is an excellent choice for this.

A five-year warranty is included. When the warranty time on a 4K display expires in five years, it will still be functional and not become obsolete.

Connection instructions to the FlexScan EV3237 for PCs

Using a 4K display to connect PCs isn’t that tough. For 4K displays, a refresh rate of 30Hz is possible with HDMI 1.4 or later on your PC.

There are, however, some restrictions if you desire a refresh rate of 60 Hz (4K@60Hz). The DisplayPort 1.2 or later interface is a crucial prerequisite. A 16 Gbps bandwidth is needed to support 4K@60 Hz display. In terms of bandwidth, neither DVI (including DualLink) nor HDMI 1.4 can deliver this kind of performance


4K 60 Hz display is possible with DisplayPort 1.2.


However, the color depth is YUV 4:2:0 and there is color blurring with HDMI 2.0 Level B’s 4K 60 Hz transmission capability over HDMI 1.4’s transmission bandwidth. HDMI 2.0 LEVEL A will be required to transmit 4K 60 Hz signals over HDMI, so you’ll have to wait for that. Because of this, DisplayPort 1.2 is the only way to get a 4K 60 Hz display currently.

Other than the interface, there are no restrictions on 4K 60 Hz displays, but the FlexScan EV3237 is free of any issues in this regard. This is because the FlexScan EV3237 uses DisplayPort’s SST (Single Stream Transport) method of 4K 60 Hz transmission and can display 4K without any special settings. Although some graphics cards support DisplayPort 1.2 and SST, it’s a good idea to check at the time of purchase if your card does not support both features.

DisplayPort’s MST (Multi-Stream Transport) is used by some products from other companies, and this has some drawbacks. MST splits the 4K signal into two 1920 x 2160 pixel screens, which necessitates the use of an AMD EyeFinity graphics driver extension function to combine them into a single screen.


Status of GPU Support for Flex Scan EV3237 4K Display


However, whether so much emphasis needs to be placed right now on 4K 60 Hz display is open to question. It requires quite a large amount of power to playback 4K videos at 60 Hz, and there still are not many 4K 60 Hz video sources out there. For game use, performance on the PC side is unlikely to keep up. Still, daily operations like cursor movement and scrolling are smoother at 60 Hz than at 3 0Hz. There are no particular problems with 30 Hz display, but thinking about the future, a product compatible with 4K 60 Hz display will provide greater peace of mind.

After connecting, the next step is configuring the scaling setting. In the case of Windows 8.1, it goes “Appearance and Personalization” -> “Display – Make text and other items larger or smaller.” There are presets to start with: “Smaller – 100%” (96 dpi), “Medium – 125%” (120 dpi) and “Larger – 150%” (144 dpi), but there are also custom sizes: “Extra Large – 200%” and “Extra Extra Large – 250%.” The pixel density on the FlexScan EV3237 is around 140 ppi, so we recommend using “Medium” or “Larger.”


Don’t forget the scaling setting on high pixel density displays like the FlexScan EV3237.


The harmony between high resolution and a huge screen enables a level of comfort that was before unattainable.

As was just discussed, the FlexScan EV3237 by EIZO features a pixel pitch that strikes a fair compromise between displaying content in 4K high resolution and providing a great amount of usable area on a panel that is 31.5″ wide. As a result, it satisfies the requirements of both types of users. It offers the ideal display size for taking advantage of the high 4K resolution on a personal computer.

However, the FlexScan EV3237 use an IPS panel that has a wide viewing angle to reduce changes in contrast and color when viewed from a variety of angles. Recently, some 4K displays have been introduced that employ TN panels that have a restricted viewing angle to provide a lower pricing. Even if it did not have a 4K display or a particularly large screen, the basic performance of the LCD would be quite good because it is packed to the gills with EIZO’s unique technology that provides a better picture and reduces eye strain.

Regular business use, creative work that requires a high resolution environment even though color management isn’t quite necessary, and hobby use by intermediate to advanced PC users will all benefit from a level of comfort that is unquestionably superior to that offered by full HD class displays in a variety of contexts, including computer-aided design (CAD) and day trading, both of which can benefit from the high definition and large screen features of the monitor, as well as regular PC use.

The fact that the FlexScan EV3237 is a high-end device is excellent news for consumers who place an emphasis on both quality and ease of use. It is an excellent piece of hardware that comes complete with all the components that are necessary for a 4K display at this time.

The FlexScan EV3237 should be at the top of your list of potential purchases if you are in the market for a high-definition display that has a large screen and is of excellent quality and that you will be able to depend on for the medium to long term.
