Review: 34-inch LG 5K2K UltraWide Thunderbolt 3 Display – Was it Worth the Wait? [Video]



With almost perfect timing over Apple's major MacBook Air and Mac mini update, the LG UltraWide 34WK95U screen was landed at the office last week. Would you rate this highly anticipated end of hardware release? See our LG 5K UltraWide Review for details.

Synology RT2600ac: AirPort Extreme replacement.

Note: Please note that there appears to be a compatibility issue with ] 2018 MacBook Pro with 560X GPU . This may be a temporary appointment switch for 15-inch 2018 MacBook Pro owners until this issue is resolved. There is a report on the LG website that states that last macOS 10.14.2 beta solves the problem. We have also noticed a problem with audio output to the speakers via Thunderbolt 3 connections. Both issues are highlighted below. We have reached LG for comments and will update this post with no response.

The LG UltraWide 5K screen was revealed at CES in early 2018, and I've watched for the release like a hawk. This Thunderbolt 3-enabled screen measures 34-inch diagonal, has a wide aspect ratio of 21: 9, and has a resolution of 5120-by-2160. On paper it sounds like a compelling companion for MacBook Pro, Mac mini or MacBook Air.

    More like 4.5K …

    The LG UltraWide 5K screen is not a real 5K screen because it only has 5K resolution (5,120 lines) on the horizontal x-axis. On the y-axis it has 2160 lines of vertical resolution, which are more like the one with a UHD 4K display.

    The LG UltraWide is more like a 4.5K screen than a true 5K display. It has a vertical resolution of 4K, combined with the horizontal resolution of 5K. To illustrate this, take a look at the following GIF animation:

    What conclusions can we draw from this comparison? If you're currently using a 4K screen, the LG 34WK95U is a significant upgrade in horizontal resolution, making it particularly attractive for apps with horizontal timelines like Final Cut Pro X and Adobe Premiere Pro. If you're used to a traditional 5K display – such as 5K iMac or the LG UltraFine 5K Display (hands-on) – the LG 34WK95U is actually a downgrade in usable resolution; It has less vertical property.

    It's interesting because LG used to market this screen as a "5K" display, but in updated marketing material it is noted that it is a "5K2K" display. I suppose LG realized that customers would quickly know that this screen provides less resolution than a typical 5120 × 2880 screen. With this in mind, we refer to the screen as a 5K2K display from here.

    The amount of real estate displayed on 4K screens

    Of course, a 21: 9 screen is a completely different animal than the typical 16:10 or 16: 9 display, as it is on traditional displays . With that in mind, LG's 5K2K UltraWide will not be for everyone, but for those who come from a 4K or less resolution, especially after a wide-screen experience, LG's hardware delivers to a large extent.

    LG UltraWide 5K2K Screen Provides Much More Horizontal Resolution

    What seems to me the most about this screen is that it has enough pixel real estate to support pixel diverting, lenders users an effective widescreen standard "Retina" Resolution of 2560 x 1080. For timeline-heavy apps, there's only enough vertical resolution to get things done and be comfortable for your eyes. I would never dream about running this, or any other 4K or 5K screen at original resolution, as the assets and text on the screen are any small when done.

    Nano IPS

    One of the buzzwords surrounding the Launch of the 34WK95U is Nano IPS, a new LCD technology developed by LG. While LG does not go deep into the specifications of Nano IPS, it is noted that the technology results in improved color for consumer displays. In fact, the 34WK95U has 98% coverage of the DCI-P3 color space, resulting in enhanced wide color support.

    LG 5K2K UltraWide passes WebKit Display P3 wide color test

    Released in 2017 with the release of 32UK950 32-inch UHD 4K screen, this is not the first excursion for Nano IPS. LG notes that Nano IPS involves an application of nanometer size particles to the monitor's LED to absorb excess lightwavelengths. The result, according to LG, is greater intensity and purity of color on the screen. It also results in displaying VESA certified DisplayHDR 600 compatible brand for enhanced high dynamic range support.

    LG34WK95U is not as bright as the 5K iMac display, but stays at 450nm maximum brightness. The device has a light sensor on the surroundings at the top of the display (due to the small settings) for auto brightness, which can change in settings.

    Ambient Light Sensor Location

    The display panel is not shiny like 5K iMac, which helps reflections and ambient light, but I feel that anti-reflective properties should be stronger. With my pancake studio lights placed several meters behind the screen, I found myself having to turn up the brightness quite a bit, which could be a side effect of the strangely placed ambient light sensor.

    Angles that you should expect from an IPS panel are good. As long as the backlight of the display sweeps out enough lumens to compensate for ambient light, Off-Axis View displays readable on screen properties.

    34WK95U has a contrast ratio of 1200: 1, and for this unschooled eye, black levels work well. With a backlit IPS screen this wide, I was not surprised to see background illumination on the edges of the screen in a dark setting.

    Although LG does not go into detail, the UltraWide screen supports local dimmering with different zones around the panel. Using a simple local dimensional test on YouTube, I could bring a noticeable difference to black levels with local dimmering active against being inactive.

    A single test confirms that LG's display has more local dimming zones

    Many inputs and power supplies

    LG's 34-inch UltraWide has both DisplayPort 1.4 and HDMI inputs, but this screen was designed with Thunderbolt 3 connection in mind. As such, you will benefit from the easy connectivity offered by modern Mac with Thunderbolt 3 in tow. As it stands now, the LG 34WK95U will work with the following Macs via Thunderbolt 3:

    For laptops like MacBook Pro and MacBook Air, the display's power supply via the Thunderbolt 3 cable is another benefit to consider. It provides up to 85 watts of power, enough to charge a 15-inch MacBook Pro machine at full speed.

    Full Power Supply via Thunderbolt 3

    It's not to say that LG's new screen will not work with other computers because it will. You can still utilize the DisplayPort or HDMI inputs for devices that lack Thunderbolt 3 ports.

    LG 5K2K display offers a range of I / O

    You can take advantage of the display's original resolution using DisplayPort 1.2 or higher. However, HDMI 2.0 connections are covered by a 4K resolution of 3840 × 2160, with ugly column boxes on both sides of the image. The default resolution for HDMI 2.0 connections is 3440 × 1440, which fills the entire screen but is an obvious downgrade on the screen display.

    It's unnecessary to say that LG does not have an HDMI cable in the box. You will stick with Thunderbolt 3 if possible or if you use an eGPU without Thunderbolt 3 passwords, such as Razer Core X (review), you will use DisplayPort.

    LG contains a white 2-meter Thunderbolt 3 cable

    Together with the individual DisplayPort and dual HDMI ports, there is a USB-3.0 3.0 port and a pair of USB-A 3.0- gates – both available through Thunderbolt 3. If you do not use Thunderbolt 3, the 34WK95U can still be used as a USB hub if you connect to the Mac via the USB B port.

    There is also a white DisplayPort cable that comes with

    If you need even more I / O, you'd rather connect your Mac directly to something like CalDigits TS3 Plus Thunderbolt 3 Dock in a daisy-chain setup. Using a Thunderbolt 3 Dock gives you plenty of extra I / O, while enjoying single cable connectivity and power.

    The last paragraph I / O as you & # 39; I find at the back of the screen is a 3.5 mm headphone jack, which lets you listen to music sent via the screen via HDMI or DisplayPort. For whatever reason, I could not send music via the monitor speakers or 3.5 mm headphone jack via the Thunderbolt 3 connection. Hopefully, this is just an error that can be solved through a software update.

    Unboxing and setting up

    The setup can be achieved in just a few minutes thanks to the fast-mounted mounting plate on the back of the screen. Simply connect the stand to the arm via the built-in thumb and lock the lever in place using the quick-release plate.

    LG delivers a white 2 meter long Thunderbolt 3 cable used to connect the monitor to your Mac of your choice. The obvious candidates – MacBook Pro, MacBook Air and Mac mini – all work well, but it can also connect to iMac or iMac Pro via Thunderbolt 3.

    The power cord of the monitor is just that – a cable. In other words, it is not a disgusting power to fight. And the cable is long enough to accommodate most reasonable setup scenarios.

    34WK95U rests on top of a metal frame that has a curved design, but the screen itself is flat. For a pro-oriented product, I'm glad that LG has a flat screen, as arched monitors introduce small amounts of distortion.

    Adjustments

    One of the most important features of any good display is adjustability; The more adjustments the user can make, the better. 34WK95U is not the most versatile screen for adjustments, but it has enough to make most users happy.

    The arm swings up and down to change the display height, up to 110 mm, and it is also -5 ~ 15 degrees tilt. There is no rotation for the screen, which would be almost impossible, regardless of its screen shape factor, but there are a few degrees of play to ensure that the screen is aligned parallel to the rest area.

    [19659042] For those who are not satisfied with the adjustability of the tripod, the 34WK95U includes VESA mounting holes behind the tripod panel for mounting on a third party screen arm, tripod or wall mount.

    Building Quality

    It's no surprise that LG's display is worse than the quality of the Apple Thunderbolt Display and 5K iMac. As is the case with almost all third party displays, the device consists primarily of plastic.

    The base is metal but the arm and everything else is plastic

    Even the arm that holds the display on the stand is made of plastic that is painted to look like the metal. The only metal component contained in the package is the base frame, which needs the weight that the metal provides to prevent it from leaving.

    I want actors to make more efforts to cut the build quality, but it's hard to turn on LG to make a plastic monitor when almost everybody else does.

    It's mostly plastic, other than high-quality plastic

    Like most monitors that can be raised, the LG screen becomes more wobbly, the higher you go. For best possible stability, you will keep the monitor as close to the base as possible. At the highest, only keyboard features can cause the screen to move subtly, but this phenomenon is mostly eliminated at lower heights.

    I appreciate the small bracelets of LG 5K2K UltraWide, which really makes the wide screen pop. The device uses a design similar to the edge of the edge glass design found on the MacBook Pro. Unfortunately, the design of the LG34WK95U is not as clean as you can see where the edges meet in the corners of the display. It's a small detail that you really need to look for, but I have to be honest and say it looks low budget.

    Notice the line where the edges meet

    Adjust display settings

    All display settings are controlled via the clickable four-way joystick nub on the bottom of the display. LG's OSD is relatively intuitive and easy to use. Moving around the display interface is done with four way joystick while a click on the joystick confirms your selections.

    You can quickly adjust the speaker volume by clicking left or right on the joystick. When you click forward on the controller while the volume controls appear, switches off. Like most monitors with built-in speakers, the 34WK95U's two 5W speakers are just good enough to get by, but you'll definitely choose headphones or a dedicated standalone speakerphone.

    When you click on the joystick, you get up the popup menu, which allows you to jump directly to important areas, such as input, image mode, settings and turn off.

    Select Settings brings up the entire sword of screen settings, which includes things like local dimming, auto brightness, PBP, DisplayPort version and more.

    Unfortunately, as mentioned at the beginning, there appear to be known compatibility issues with the 15-inch 2018 MacBook Pro, which I've heard that LG is working to address. I do not own a 2018 MacBook Pro, so I have not managed to see these issues to myself. All my other Macs, a 2017 MacBook Pro, 2017 Mac Mac Pro and 2018 Mac mini. Everything works fine with LG UltraWide when connected via Thunderbolt 3 with DisplayPort 1.2.

    If you regularly work with content that benefits from a wide display area, and you are currently using a 4K resolution or below screen, the LG UltraWide 34WK95U is a significant workplace upgrade. Having extra horizontal real estate can go a long way towards improving your productivity, and the overall sense of working in programs like Final Cut Pro X, Premiere Pro and Logic Pro X is enhanced.

    From a 4K screen, 34WK95U is an upgrade

    This screen really shows the tool when it is connected to a Thunderbolt 3 enabled Mac, especially MacBook Pro or MacBook Air, so it can leave these the machines together to function as primary or secondary display. It's not very useful when connecting HDMI sources, but DisplayPort is a good secondary option that provides full resolution if necessary.

    As good as the Thunderbolt 3 connection, I'm astonished at the lack of audio output for the screen speakers when using Thunderbolt 3. This is something that will hopefully be resolved through a future software update. We have reached LG for comment.

    Thunderbolt 3 is the Preferred Connection Method

    It is annoying that third-party manufacturers continue to manufacture products made mainly of plastic, especially at this price, but to consumers vote with the wallet, I see not this trend changes.

    Almost everything … is plastic

    With its 21: 9 ratio, the LG UltraWide 34WK95U is for people who work with content enhanced by a broader field of view. If it's not you, you'd like a screen with a 16: 9 or 16:10 aspect ratio.

    But if you are a creative professional who knows what you get into, this screen shows a significant property upgrade from 4K. Just make sure you understand that this really is a 4.5k screen, and it does not provide any resolution advantage over a true 5K screen like that found in 5K iMac or iMac Pro.

    As long as you know that this screen is practical limitations and can take advantage of its strengths, it's a valuable investment that can improve your productivity if you are properly.

    You can find LG 5K2K UltraWide on B & H sales for $ 1399. What are your thoughts on this screen? Would you consider adding it to your desktop, and if so, which Mac are you planning to pair it with? Sound down below in the comments.
