- 1 Two types of 4K
- 2 Notes concerning connecting PCs to the FlexScan EV3237
Enter the EIZO 4K display, which meets the needs of high-definition and large screen size
Full HD liquid crystal displays were once considered high-end, but in recent years, the prices have come down well, and today 23 ” full HD models have penetrated the domestic market to the point of becoming independent stream. Around the time of the passage to sublunar digital broadcasting, the stir to full HD displays accelerated. Although there was a perception of stagnation following that, the future brandish has ultimately rolled in. Of course, this was brought about by the raise of 4K displays .
” 4K ” refers to horizontal resolutions of around 4,000 pixels. The “ K ” stands for “ kilogram ” ( thousand ). As things stand, the majority of 4K displays come with 3840 ten 2160 pixel ( 4K UHDTV ) resolution, which is precisely four times the pixel count of entire HD displays ( 1920 ten 1080 pixels ). There are besides 4096 x 2160 pixel ( DCI 4K ) displays for the film diligence that are referred to as 4K displays.
Two types of 4K
- 3840 x 2160 pixels (4K UHD)
4K UHD is 4K as defined by the ITU ( International Telecommunication Union ). It has doubly the horizontal and upright solution of full HD and has been adopted by the television receiver diligence .
- 4096 x 2160 pixels (DCI 4K)
DCI 4K is 4K as defined by DCI ( Digital Cinema Initiatives ). The horizontal settlement is higher than 4K UHD. This resolution is doubly the horizontal and vertical resolution of projectors ( 2048 ten 1080 pixels ) and has been adopted by the film industry .
Against a backdrop of always higher digital television camera photograph resolutions, higher resolution capacity of home video recording cameras supporting 4K, increasingly high definition displays on smartphones and tablets, and other such developments, broad HD displays on PCs are becoming less and less attractive. At the lapp time, interest is increasing in big screens and multi-screen environments that allow larger ferment spaces to increase the efficiency of multi-tasking, which is substantive for PCs .
In the midst of these circumstances, EIZO introduced its much-awaited new FlexScan EV3237 expose. This new flagship model with a boastfully 31.5 ” wide sieve ( visible diagonal size : 79.9 centimeter ) is the inaugural of its universal displays to support 3840 ten 2160 pixel 4K resolving power. It ‘s a high-end expose for a raw historic period that meets the two needs of high-definition and a bombastic bring outer space with top-level spectacles .
EIZO ‘s 31.5 ” FlexScan EV3237 4K expose
That said, there are credibly many out there who wonder whether it ‘s still excessively early to buy a 4K display. In this article, we ‘ll take a look at how the FlexScan EV3237 4K display can solve problems and complaints frequently experienced in display environments of late in Q & A format. We think you ‘ll see that the FlexScan EV3237 should be one of the purchase candidates on your tilt right now .
EIZO’s 4K display intelligently solves common complaints about displays!
Q I ‘ve gotten used to the high-definition display on my smartphone, pad or laptop, and now the riddle on my external display looks rough and numb to me. Is this equitable how it is ?
A The detail on displays is expressed in terms of pixel concentration or definition, and the numeral representation of that degree is expressed in ppi. Ppi stands for “ pixels per edge. ” Reducing the distance between pixels ( pixel lurch ) without changing the screen size of the LCD dialog box increases the ppi, and the higher this number, the higher the definition of the display .
Pixel concentration on smartphones is increasing at a angered pace, and many smartphones nowadays have pixel densities of 300 ppi or more. The display is so politic that even if you look close at the screen you can not see pixel grains or jagged diagonal lines. There are besides some high-end devices that are about overkill and exceed 500 ppi .
When it comes to PC displays, most products have a pixel density of about 96 ppi to match the display concentration of 96 dpi ( department of transportation per edge ) which has been the standard for the Windows background UI. The standard for the new Start sieve and other aspects of the Modern UI of Windows 8 and subsequently is 135 dpi ( automatically switching between 100 %, 140 % and 180 % depending on the pixel density of the expose device ), but the standard for the desktop UI is still 96 dpi. So it ‘s no surprise that the display looks rough in comparison to smartphones .
|Different pixel densities create differences in appearance. The image on top is of an enlarge 10 platinum font, and the image below is an blow up thumbnail of a photograph. At 96 ppi, the crudeness of the pixels is apparent, but at 192 ppi, the timbre is greatly improved. At 384 ppi, the image is smooth, and the pixel grains and jagged edges of aslant lines are no longer visible .|
however, the expose concentration ( dpi ) of personal computer operating systems is now variable, so smooth enlargement is now possible with scaling according to the pixel density of the display. Since Windows XP, it has been possible to change the display concentration on Windows OS, but it was n’t until Windows 7 that it could be done at a hardheaded grade where the screen layout did not break down significantly .
Since Windows 8.1, it has been possible to apply different expose density settings to different displays when multiple displays are connected, and the sense of incongruity experienced in a multi-screen environment with displays of different pixel densities has been reduced ( however, the number of setting levels is limited, so the combination of display densities can not be elaborately customized ) .
Mac OS X has besides adopted a design even earlier Windows that allows expose concentration to be changed on high-definition displays ( referred to as “ Retina displays ” by Apple ). Since OS X Mavericks 10.9.3, this support has been available for external displays .
support for the high pixel density display environment in the personal computer OS is called HiDPI accompaniment. Along with support on the OS side, support by applications is besides progressing, and the personal computer environment surrounding HiDPI has risen to a practical level. consequently, high gear pixel concentration personal computer displays are on the ascend .
The FlexScan EV3237 is one of those products, and as a large-screen external expose, it has a high-definition pixel density of around 140 ppi. This is quite low in comparison to the pixel density of smartphones mentioned earlier, but note that the distance at which smartphones and personal computer displays are used is quite different .
In the case of the 31.5 ” FlexScan EV3237, people use it from a distance of around 50-60 centimeters, so the display appears a placid as that of smartphones. furthermore, the display size is dramatically larger than that of smartphones, so a lot more information can be seen at once. Photographs and movies are more impressive, besides .
|The 31.5 ” FlexScan EV3237 is viewed from a much greater outdistance than smartphones, tablets and laptops, so even with a pixel concentration of around 140 ppi, the display appears smooth and high-definition. It ‘s unvoiced to tell from photograph, but watching a high-definition video at 4K resolution on a 31.5 ” wide blind ( roughly 80 centimeters diagonally from corner to corner ) is an amazing experience that can not be enjoyed with a full HD display .|
Q I ‘d like to increase my work efficiency, but I do n’t have enough space for a multi-display apparatus. I besides do n’t like having a frame between the screens. Is there a way to increase work efficiency with a single screen ?
A There are basically two patterns when it comes to environments where multiple displays are lined up side by english. One is where multiple displays are connected to make more work quad for a single personal computer. The other is where information is displayed from multiple PCs to work in parallel .
The FlexScan EV3237 can be used for either purpose. First, in the former casing, the 31.5 ” across-the-board LCD jury with 4K resoluteness offers a bombastic ferment space ( however, magnification via scaling besides has to be taken into report ; more details are provided late ) .
In the latter subject, image input from four systems ( DisplayPort x 2, HDMI x 1 and DVI-D 24-pin x 1 ) coupled with PbyP ( Picture by Picture ) and PinP ( Picture in Picture ) functions, which can simultaneously display multiple image signals, comes into play .
|FlexScan EV3237 input terminals. From left to right : DVI-D, HDMI and two DisplayPort 1.2 terminals. To the right of these are the USB 3.0 hub ’ s upriver port and channel input signal. There is a built-in power add unit, and it is besides equipped with a independent baron trade to cut power consumption when not in use. It ‘s besides equipped with three USB 3.0 downriver ports and a earphone ojack on the leave side .|
Using the picture-by-picture ( PbyP ) routine, images from multiple Sources can be displayed side by side on the large screen. PbyP supports many display modes : horizontal burst ( two 3840 x 1080 pixel screens ), vertical divide ( two 1920 x 2160 pixel screens ), horizontally splitting the bequeath ( or correct ) half ( 1920 adam 2160 pixel + two broad HD screens ) and splitting both horizontally and vertically into four screens ( four wide HD screens ) .
There are never any lines dividing the screens with any of the settings, which means that the multi-display setup is wholly frameless, so it ‘s easy to use. Incidentally, with four-screen display, it ‘s like having four 15-16 ” fully HD displays side by side without any gaps between them .
|With the PbyP function, double signals from multiple PCs can be simultaneously displayed side by side on a single screen. There are five layouts to choose from. It ‘s besides conceivable that it could be used like digital signage for coincident display of video, advertisements and other information .|
With the PbyP function, double signals from multiple PCs can be simultaneously displayed side by side on a single screen. There are five layouts to choose from. It ‘s besides conceivable that it could be used like digital signage for coincident display of television, advertisements and other information .
|Three prototype signals displayed side by side using the PbyP function. The left half is 1920 ten 2160 pixels, and the lead and bottom of the correct half are both 1920 ten 1080 pixels. Taking advantage of the big 31.5 ” screen and high definition 4K display, a multi-display setup can be achieved with no frames between screens .|
On the other hand, if a little sub-screen is enough, using the picture-in-picture ( PinP ) function, you can do parallel cultivate while taking advantage of the large display area. There are two sizes of sub-screens to choose from, and they can be placed in any corner .
|The PinP function is besides available, allowing a modest sub-screen to be overlaid on the main large filmdom. One manner it might be used is to play a stream video of a general meeting of shareholders in a sub-screen while day trade in the main screen .|
|Sub-screen expose in the upper right corner using the PinP routine. The sub-screen is smaller than the minimum size offered by PbyP, allowing more of the main screen to be used, so it is suited to uses like working while playing a video .|
Q Full HD ( 1920 x 1080 ) and WUXGA ( 1920 x 1200 ) leave something to be desired when editing high pixel photograph and video. Should I go with WQHD or ultra-wide ( CinemaScope ) ? Or should I choose 4K already ?
A The gap of 4K may be faster than expected. From a broadcast point of view, there are major movements afoot in the United States, South Korea and other countries. In Japan, there is an accelerate road map being worked on for 4K/8K broadcasts. In the personal computer world, the environment has been prepared for HiDPI, and products have been hitting the shelves all at once. additionally, game manufacturers have begun talking about 4K accompaniment with new games ( even though the command spectacles are shockingly high ). In the orgasm months, there will be increasing requirement for 4K displays, and manufacturers will likely accelerate their product .
Going one notch down and choosing WQHD ( 2560 adam 1440 pixels ) or casting aside versatility and going with ultra-wide ( e.g. 21:9 aspect ratio/2560 ten 1080 pixels ) would not be ill-advised as an “ in-between ” until 4K becomes main current. These do not have the pixel density of 4K displays, so magnification with scaling is not required, and it ‘s easy to secure a large work outer space. At this steer in time, they besides have an advantage in terms of price .
however, if you already have a personal computer environment for 4K display at this compass point in time, and want a high-definition display that you will use for many years to come, there is no argue to hold off on the FlexScan EV3237. conversely, displays under 4K may promptly become disused, sol if you are thinking of medium- to long-run consumption, a 4K expose may work for you longer and, as a result, pay for itself over prison term .
|EIZO ‘s 27 ” FlexScan EV2736W broad LCD. The resolution is WQHD ( 2560 x 1440 pixels/109ppi ). Before the FlexScan EV3237, this was the flagship model of the FlexScan EV series, but if you are just immediately starting to look at different products, you should include 4K displays in your circumstance .|
Q I bought a laptop with a extremely high gear pixel density expose, but it ‘s not practical unless I use scaling to magnify the display 150-200 %. Wo n’t a 4K expose ultimately be the lapp ?
A As mentioned earlier, today as HiDPI has reached a practical degree, more and more laptops are being equipped with high-definition LCDs. These products offer high-definition display as the sell point with the assumption that scaling will be used for magnification, thus high resolution does not mean a large work space as it did when display concentration was assumed to be fixed .
Visibility and legibility are greatly affected by pixel cant, but the outdistance at which laptops are viewed is closer than it is with external displays, so pixel concentration is higher ( approx. 220ppi on a 13.3 ” 2560 ten 1440 pixel display ), which means that pixel pitch is that much narrower ( approx. 0.12mm ). At 100 % magnification without scaling, text and icon display is excessively very well.

At the same time, the pixel pitch on the FlexScan EV3237 is besides specialize owing to the high-definition display. For example, if you wanted to keep the lapp pixel flip ( approx. 0.27mm ) as a presently main stream 23 ” wax HD display with a 4K resolution display, you would need to double the riddle size with a 46 ” display. This is crammed into a 31.5 ” display, so the pixel peddle is naturally narrower .
That said, the big 31.5 ” filmdom means that it ‘s not indeed highly fine as it would be on a 23.8 ” or 28 ” 4K display. The pixel pitch is about 0.18 mm, thus if you pick the right installation placement and adjust the watch distance, it ‘s available without scaling. however, when using a large 31.5 ” screen up stopping point, it places more stress on the eyes and neck, so it ‘s advisable to use the scale sport .
The pixel pitch is not excessively narrow, sol not much enlargement is required. Under the Windows DPI Display Size settings, it ‘s pretty available from around “ Flickroom – 125 % ” and up, so you can have both high-definition display and a large shape outer space. If you want to have it around a standard 23 ” full HD display ( approx. 96 ppi ), you can set it to “ Larger – 150 % ” to get the display to about the same text size .
|On the leave is “ Smaller – 100 %, ” and on the mighty is “ Flickroom – 125 %. ” The size and definition of the picture and text changes .|
|On the leave is “ Larger – 150 %, ” and on the right is “ Extra Large – 200 %. ” When set to 150％, the Windows desktop UI is close to the standard 96 dpi ( 103 % compared to the standard 96 dpi ) .|
|Display area at “ Smaller – 100 %. ” This is convention exaggeration, and the 3840 adam 2160 pixel 4K solution can be used to the fullest. The pixel density is about 140 ppi, and the pixel pitch is approximately 0.18mm. This plant is not unserviceable, but the filmdom is easier to see at “ Flickroom – 125 % ” or “ Larger – 150 %. ”|
|Display area at “ Larger – 150 %. ” scale is used for 150 % enlargement, so the work outer space is smaller, but the text and icons are that much more visible. This set is optimum if you want the Windows desktop UI at around the standard 96dpi. This setting offers a counterweight between definition and oeuvre outer space .|
|On the exit is the FlexScan EV3237 ( 31.5 ” /3840 ten 2160 pixels/approx. 140 ppi ), and on the right is the FlexScan EV2436W-Z ( 24.1 ” /1920 ten 1200 pixels/approx. 94 ppi ). When the FlexScan EV3237 is set to 150 % enlargement, the appearance of the text and icons is about the lapp as on the FlexScan EV2436W-Z at normal enlargement. even at 150 % exaggeration, taking advantage of the 31.5 ” wide shield, you can secure a large function space .|

|Although the viewing distance besides comes into meet, if the pixel pitch is narrower than around 0.2 millimeter, regular practice becomes more unmanageable at normal exaggeration, so the magnification has to be increased with the scaling set .|
Q Are n’t very large-screen, high-definition displays harder on the eyes and shoulders ?
A It ‘s necessary to be mindful of diverse things to mitigate the effect placed on the eyes, neck and shoulders by working on a personal computer. The minimum necessity of displays is that the LCD panel coat is non-glare to minimize observation and that the brightness, acme and angle can be adjusted .
generally speaking, large-screen, high-definition display environments tend to place stress on the eyes and shoulders, but the FlexScan EV3237 has many features to reduce that stress. The FlexStand is familiar to EIZO users and features a large stove of motion, allowing rock, pivot, and up-and-down adjustments. The significant adjustability and polish movement makes it suited to any usage environment .
The same goes for brightness alteration. It starts from very dark expose, so it can be matched to the brightness of the environment. however, the most effective have is “ Auto EcoView. ” The built-in illuminance detector detects ambient brightness and automatically adjusts the display to the optimum luminosity, so evening in an environment where brightness changes, the exploiter does not have to bother with it .
It besides has assorted early features such as “ Paper Mode, ” which substantially reduces blue light, and “ EyeCare Dimming, ” which controls flickering caused by the LED backlight, so a major advantage is that the stress on the eyes can be mitigated without conscious effort on the region of the user .
|The height is highly adjustable, and the riddle can be lowered equitable above the initiation surface, so even the large models can be set up so that you naturally look down at the display .|
|The Auto EcoView have offers both energy savings and relief for banal eyes. It is easily configured using the OSD menu from the button on the presence of the LCD ( left ). Starting with this new model, users can customize the maximal and minimum values for automatic brightness allowance ( right ) .|
|When the button on the front is pressed, the menu appears right above, so it ‘s easy to use. This menu enables a simpleton appearance with no markings over buttons other than the power button .|
Q I want a high-grade display that I will be able to use faithfully for a long meter. Which one should I choose ?
A Large-screen displays in this course are not cheap, so it ‘s merely natural that you would want to choose a reliable one that you will be able to use for a retentive time. The FlexScan EV3237 meets this necessity solidly adenine well .
It comes with a long, five-year guarantee. Five years from now when the guarantee time period is up, a 4K display will still be available and will not be disused .
Notes concerning connecting PCs to the FlexScan EV3237
It ‘s not that difficult to connect PCs to a 4K display. If your personal computer has an HDMI port that supports HDMI 1.4 or former, 4K display is possible at a refresh rate of 30Hz .
however, if you want a refresh rate of 60 Hz ( 4K @ 60Hz ), there are some limitations. A major precondition is that the interface is DisplayPort 1.2 or by and by. 4K @ 60 Hz display requires a identical bombastic infection bandwidth of 16 Gbps. Neither DVI ( including DualLink ) nor HDMI 1.4 is able of this kind of bandwidth .
4K 60 Hz display is potential with DisplayPort 1.2 .
The HDMI 2.0 Level B standard is capable of transmitting 4K 60 Hz signals over the HDMI 1.4 infection bandwidth, but the color depth is YUV 4:2:0, and colors blur, so it is not suited to displays. so you ‘ll have to wait for HDMI 2.0 LEVEL A to transmit 4K 60 Hz signals over HDMI. For that reason, DisplayPort 1.2 is presently the only means of achieving 4K 60 Hz display .
As for early limitations on 4K 60 Hz display besides the interface, they vary depending on the display, but there are basically no problems when it comes to the FlexScan EV3237. This is because SST ( Single Stream Transport ) is the method acting of 4K 60 Hz transmittance used by the FlexScan EV3237 via DisplayPort, and it is capable of 4K display without any special settings. however, there are some graphics cards that support DisplayPort 1.2 but do not support SST, so it would be a good theme to check at the time of purchase precisely in lawsuit .
Some products from other companies use DisplayPort ‘s MST ( Multi-Stream Transport ) as the method of transmittance and this creates some limitations. With the MST method acting, the 4K sign is split in two ( two 1920 adam 2160 pixel screens ), so the graphics driver ‘s extension function ( such as AMD ‘s EyeFinity ) has to be used to combine them into a single shield .
|Status of GPU Support for Flex Scan EV3237 4K Display|
|Manufacturer||Product||DisplayPort (3840 x 2160 pixels/60Hz)|
|AMD||Radeon HD 7700 or later||Yes|
|Radeon R7 or later||Yes|
|Fire Pro W series or later||Yes|
|NVIDIA||GeForce GT x 650 or later||Yes|
|Quadro K series or later||Yes|
|Intel||HD Graphics 4200 or later||Yes|
|Apple||Mac Pro (Late 2013, OS x 10.9.3 or later)||Yes|
however, whether so much stress needs to be placed right now on 4K 60 Hz display is open to question. It requires quite a large amount of office to playback 4K videos at 60 Hz, and there placid are not many 4K 60 Hz video Sources out there. For game manipulation, performance on the personal computer side is unlikely to keep up. still, casual operations like cursor movement and scroll are smoother at 60 Hz than at 3 0Hz. There are no particular problems with 30 Hz expose, but thinking about the future, a product compatible with 4K 60 Hz display will provide greater peace of thinker .
After connecting, the next step is configuring the scale 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 ), “ Flickroom – 125 % ” ( 120 dpi ) and “ Larger – 150 % ” ( 144 dpi ), but there are besides custom-made sizes : “ Extra Large – 200 % ” and “ Extra Extra Large – 250 %. ” The pixel density on the FlexScan EV3237 is approximately 140 ppi, so we recommend using “ Flickroom ” or “ Larger. ”
Do n’t forget the scale setting on high pixel concentration displays like the FlexScan EV3237 .
As explained above, EIZO ‘s FlexScan EV3237 has a pixel sales talk that strikes a beneficial balance between 4K high definition display and a large work outer space on a 31.5 ” wide screen, so it meets both needs. It has the perfect shield size for enjoying the high 4K resolution on a personal computer .
recently there have been some 4K displays coming out that use TN panels with a narrow viewing slant to provide a lower price, but the FlexScan EV3237 uses an IPS dialog box with a wide-eyed viewing angle to minimize contrast and color changes at different angles. Of course, it ‘s chock full of EIZO ‘s proprietorship engineering for better video and relief of eye tire, so the basic performance as an LCD is gamey even without the 4K display and large screen .
You ‘ll undoubtedly enjoy a level of ease that army for the liberation of rwanda surpasses that of full HD class displays in respective scenarios, from CAD and day trade that can leverage the high definition and bombastic shield features, to regular business use, creative work that requires a high solution environment even though coloring material management is n’t quite necessary, and hobby use by intercede to advance personal computer users .
The FlexScan EV3237 is a high-end model, which is good news for those users that prioritize timbre and serviceability. It ‘s a high-quality device that comes with all the elements presently required of a 4K display .
If you ‘re looking for a high-quality, large-screen high-definition display that you will be able to use with peace of mind in the medium to long term, the FlexScan EV3237 is one of the leading candidates for your number .
|In accession to the boastfully screen and high definition, it besides has high-quality display, featuring an IPS panel with a wide view slant and offering politic grade with 10-bit gamma correction. The spectrum is equivalent to sRGB .|
