Lg 34wk95u

The LG 34WK95U-W monitor is in our recommended guide, and we wanted to do this review to see first-hand the benefits of its powerful 5K2K resolution Nano IPS panel. A monitor whose use is clearly design-oriented, in fact having a TIPA award for best monitor for photography.

Among its most outstanding features we have Thunderbolt 3 connectivity, 98% DCI-P3 coverage, a large factory calibration and a refined design with ultra panoramic flat panel ideal for working. Without further ado, let's start with the review!

Before, we thank LG for having trusted us to temporarily give us this monitor and to be able to do its analysis.

LG 34WK95U-W technical characteristics

Unboxing

We begin this analysis as always with the Unboxing of the LG 34WK95U-W, a monitor that will arrive in a rigid cardboard box of considerable dimensions, especially long. In it we do not have any handle to transport it, but we do have two typical side grips. The outer part is decorated in a very striking way with the monitor showing a landscape on a white background to denote that it is design-oriented.

We open the box at the top, finding an expanded polystyrene mold (white cork) made up of two pieces. These hold the monitor from above and below, thus preventing it from breaking during transport or with a blow. This method allows us to better unpack the components than the sandwich type, so well done by LG.

The bundle in this case has the following elements:

• LG 34WK95U-W display Feet Hydraulic bracket DisplayPortUSB Type-C Thunderbolt 3 cableUSB Type-B data cable 230V power cable

The monitor in this case comes with the three parts disassembled to optimize the measurements of the box. In this case, the USB Type-B cable should come in the bundle, since in its specifications it counts as included. We say these because it does not appear in our captures. This cable will give us support for the LG OnScreen Control software, which we can also use with Thunderbolt 3.

Otherwise we have what was expected, although we would have liked to see a panel calibration report. Perhaps this comes on the monitors for sale to the public, which we also do not know. In any case, that's what we are for, and we will discuss the calibration in the corresponding section.

Bracket design and mounting

As the LG 34WK95U-W monitor is disassembled, we will take the opportunity to see in detail the support that LG has designed for it.

Starting at the base, we have a design exactly like the LG 27UK850-W that we recently purchased for our facilities. This is understandable since they are ultimately from the same generation so to speak and also design-oriented. It is a half-moon design base entirely made of aluminum, very light and with the assembly mechanism in the central part.

The support arm is also made of aluminum in the shape of a hollow cylinder with two diameters to allow one to fit over the other when we modify its height. And it is that inside we have a hydraulic mechanism with a total travel of 110 mm relatively smooth and easy to handle.

We assemble these two pieces with a simple manual thread screw integrated on the base, and which will keep the two elements well fastened and without rocking. The support takes up quite little space, having a depth of 234 mm due to the design of its legs mainly. In addition, it is very light as a whole, just over 1 kg, so the entire step falls on the screen.

We only have to see the support mechanism for the screen of the LG 34WK95U-W, which is a VESA variant of 100 × 100 mm with a quick installation system and without screws thanks to two upper tabs and two lower tabs that fit over a lock automatically. To separate the two elements again we will only have to move down a button located on the back of the support and that's it. Outwardly it has a white plastic trim.

Ultra Wide 5K display: package design

Well, we already have the LG 34WK95U-W mounted, leaving an aspect that inevitably reminds us a lot of the MSI Prestige PS341WU, then we will study that the image panel is very very similar in performance.

The monitor stands out mainly for its ultra wide or ultra wide design that offers a 21: 9 image format. For better comfort in the field of design, it has been chosen to keep it completely flat, the usual thing in these cases being a curvature, especially in gaming monitors. This will give us an image without distortion and better control over measurements if we are working with CAD or BIM drawings.

The panel is designed with ultra slim frames, which in turn are directly integrated into the screen glass measuring about 10mm on all four sides. So we don't even have a plastic frame on the bottom, thus improving its finishes and the useful surface by more than 90%. The anti-glare finish of the panel is quite good, blurring the lights that directly affect it well.

Focusing now on the back of the LG 34WK95U-W, we have opted for a thick plastic housing entirely in matt white and with an angular design and straight faces that are not common in these times. One positive thing about accessibility is that the port panel is located on the main face, and not on the bottom edge like most. It is good for being very accessible, thus avoiding physical frames at the bottom, although we must be careful with the ports and do not pull on the cables, since they could bend when they have a horizontal orientation.

In the monitor support we have a small router for these cables that will allow them to be hidden as possible. What we do have in the lower frame is the joystick to control the OSD and turn the equipment on and off, being in fact the only button there is. In the upper frame we have the ambient light sensor for the automatic brightness mode.

We see that in general it is a fairly minimalist design, based on light colors as is usual in monitors not optimized for gaming and where its shallow depth stands out, ideal for narrow desktops. We only see improvement in the grip of the support and screen, since it has been reduced to the minimum expression and the truth is that it wobbles quite a bit, and its width does not help.

Ergonomics

We are not finished with its design, because now we dedicate a small section to the ergonomics of the LG 34WK95U-W, which will be good considering the proportions of the panel.

The aluminum hydraulic support gives us a vertical movement range of 110 mm, being relatively wide and of which we have no complaints. It is well designed and really discreet, but as we've discussed before, it wobbles a bit.

The other degree of freedom that we will have unlocked is that of the horizontal orientation or X axis if we prefer to call it that. We can orient the screen down about 5 ^or up a total of 15 ^or being a fairly standard range and enough to adapt to all kinds of high or low desks.

Along the way the vertical orientation of the Z axis has remained and of course the screen rotation is physically impossible. The just and necessary we can say, and the needs of the user are covered. It supports VESA 100 × 100 mm mounts so we can place the monitor on a generic support for example for double or triple monitor setups.

Wide connectivity

Another aspect that we consider an advantage of the LG 34WK95U-W is the wide connectivity that we have, also located in a place that is quite accessible to the user.

We will then have:

• 1x DisplayPort 1.42x HDMI 2.0b1x USB Type-C Thunderbolt 3 (83W load) 2x USB 3.1 gen1 Type-A1x USB 3.1 gen1 Type-B 3.5mm jack as audio output 3-pin 240V power input

First of all, we have the possibility to connect the monitor with 3 different video sources, with HDMI supporting the 5120x2160p resolution at 30 FPS in principle, and DisplayPort 1.4 at the 5120x2160p resolution at 60 FPS both in the dedicated connector and in Thunderbolt 3 for being the same version of the interface.

Thunderbolt also offers us an 83W charging power that is great for laptop connections. The two normal USB ports will work if we connect the monitor through Thunderbolt 3 or with USB-B to our equipment.

LG 34WK95U-W display features

Now we are going to continue analyzing all the characteristics of the screen of the LG 34WK95U-W, one of the few with 5K2K resolution on the market.

LG is one of the main manufacturers and suppliers of panels on the market, and for this reason we find equipment with similar benefits such as the aforementioned MSI Prestige where assemblers do their bit for optimization. In this case, it is a panel with 34-inch Nano IPS LED technology and an ultra panoramic design with a 21: 9 image format. In it we have a resolution of no less than 5120x2160p or 5K2K as one of the highest available, which would be like having 4 monitors in Full HD plus 33% extra space in width.

Thanks to this we have exceptional image sharpness even if we rescale to 3440x1440p, since the pixel size is only 0.1554 x 0.1554 mm which would be the equivalent of a 27-inch 4K monitor. Nano IPS technology is the most advanced in terms of LCD panels. It will offer us a priori optimal performance for precision work, since it has particles capable of filtering light waves, especially with regard to red and its range of tones. And the quality shows a lot, being an experience.

The features that LG introduces in it are a typical 1200: 1 contrast and a typical brightness of 450 nits. It also has DisplayHDR 600 certification, so in HDR mode it should give us brightness peaks equal to or greater than 600 cd / m ². With this resolution it is normal that we find a refresh rate of 60 Hz, while the response time in fast mode is 5 ms GTG, although an ultra-fast mode that speeds up this response a little more, but never comparable to the panels optimized for clear gaming. Later we will check whether or not there is ghosting. In this case, neither FreeSync nor G-Sync dynamic refresh technology is implemented, although it offers integrated Flicker-Free function as usual.

And since it's built to deliver image quality, let's focus more on these features. Because the LG 34WK95U-W has a color depth of 10 although using 8 bits + FRC, that is, an internal palette that raises an 8-bit panel to 1.07 billion colors. In this way it offers a color coverage of 98% in DCI-P3 and 100% in sRGB. The viewing angles will be 178 ^or both vertically and laterally, with an impeccable result. In the OSD we have many predefined image modes, including DCI-P3, sRGB and Rec-709, of which we will verify its calibration in the next section.

Integrated in the OSD we have the PIP mode, with which we can place a second signal in the form of a window in the corner on the main video signal. As well as the PBP mode, to place two video signals on the same screen simultaneously, come on, what has been a split screen. This can also be managed from the LG OnScreen Control software if we connect the monitor with USB-B or Thunderbolt. To this we add the DAS or Dynamic Action Sync function, although no specific gaming function such as black stabilization, game mode or crosshairs.

We do not want to skip the section without mentioning the good audio system that we have integrated, with a double 5W speaker with Rich Bass technology. A pair of speakers with surprisingly high volume and surprisingly good bass. So many as to be at the level of typical flat-panel televisions of medium and high range and that will be quite useful for a standard user in demands.

Calibration and performance tests

We will analyze the calibration characteristics of the LG 34WK95U-W, verifying that the manufacturer's technical parameters are met. For this we will use the X-Rite Colormunki Display colorimeter together with the DisplayCAL 3 and HCFR software for calibration and profiling, verifying these properties with the sRGB color space and also DCI-P3.

Flickering, ghosting and other image artifacts

We have conducted several tests with the UFO test set to 960 pixels per second and a 240 pixel separation between the UFOs always with the Cyan color background. The images taken have been tracked with the UFOs at the same speed at which they appear on the screen in order to capture the trail of ghosting that they may leave.

We only have the 60 Hz resolution available, although a total of 4 response modes for the pixels, so we have verified the result in all of them. The capture of these images is somewhat complicated and the camera also makes its own mistake in the movement.

The images are ordered as the response modes come, from Off mode to the Fastest mode. And the truth is that the experience has been at least positive, since we expected more ghosting and we have found an extremely good panel in this regard.

In fact, we only have this appreciable phenomenon in the Off mode, while the best image quality and without a trail are found in the fastest and fastest mode, although in the latter we can see a very slight blank trail indicating that we are already a little past.

Yes we see a slight blur that improves the better the response speed we have, this is normal, although we must consider the error made by the camera. It is a very good panel both in this and in other aspects, with total absence of flickering and bleeding.

Contrast and brightness

For the contrast and color tests of the LG 34WK95U-W we have used 100% of its capacity, as well as the HDR effect mode predefined in the OSD.

Measurements	Contrast	Gamma value	Color temperature	Black level
@ 100% gloss	1056: 1	2140	6157K	0.2342 cd / m 2

We have found the typical contrast level a little low, as it has been 1, 000: 1 while in the specifications 1200: 1 was promised. The gamma value we see quite well adjusted, as well as the color temperature, although tending to warm tones for being less than 6500K. In fact, it is interesting to note that, in addition to the control in 6 color axes independently, we have a section to select the desired color temperature between 6000 and 9000K.

As for the brightness, with this predefined HDR mode it is not too good in power, although it is in uniformity. The maximum power is obtained in the center of the panel with about 383 cd / m ² (nits) that does not even exceed the typical brightness established by the manufacturer of 450 nits. The truth is that in this specific aspect we expected something more.

SRGB color space

Delta sRGB mode

Delta Default mode

In this regard , the expectations are fully met with coverage in the space of 100% in relative terms and almost 145% in absolute values, being therefore much higher and perfectly covering all the most saturated values ​​of red, green and blue.

By having a specific image mode for sRGB, we wanted to compare the calibration of this mode with the standard mode and see which one fits best. And indeed in sRGB the Delta E improves a little to 2.51 on average compared to 2.85 in the standard mode, but the gray adjustment worsens slightly. Finally, the HCFR graphics show a slight luminance mismatch and a Gamma lower than the ideal space, in the same way the RGB is somewhat improvable and consequently the color temperature to tend to more neutral colors.

DCI-P3 color space

Delta mode DCI-P3

Delta Default mode

It is noted that this panel is calibrated for this DCI-P3 space, since the average Delta E is 2.14 for the specific image mode and 2.16 for the standard mode, very similar in this case. Likewise, the coverage in this space is 98.2%, thus covering what was promised, even with a very good 84.7% in Adobe RGB, a space specialized in photography.

We still see room for improvement on the grayscale, with somewhat elevated deltas that will surely improve with a good profiling and calibration now later. The graphics also improve in the space-specific sections, obviously staying the same in RGB and color temperature.

Calibration

The calibration of the LG 34WK95U-W has been carried out with DisplayCAL with the monitor at 5K2K resolution with the 10-bit color palette and the response time in "fast" mode. The rest of the values ​​have been kept at the factory and with the default image mode so as not to modify the pre-established ones.

The results that we have obtained in the Delta E after the calibration will be the following:

sRGB

DCI-P3

We knew well that the capacity of this panel was very wide, which is demonstrated by these excellent results after adjusting the RGB bars to an ideal temperature and recalibrating the color profile. In this way we achieve that the average Delta E in the LG 34WK95U-W is less than 1 in the two tested spaces (and in the rest) and with maximums of only 1.2-1.3 in warm tones.

OSD menu

The OSD Menu in this case is very simple and fast to operate, since we only have a button in the form of a 5-way joystick (cardinal points + pressure in the center) with which to take out both the quick menus and OSD, such as turning off and turn on the LG 34WK95U-W.

With just one press we will get a wheel with a quick menu for the image mode, another for the selection of the video input and a third for the main menu. Pressing directly on the arrow keys we will see the volume bar and the current connection, nothing more.

The main menu is divided into only 4 sections, although they are well-stocked with options since it occupies the entire height of the panel just to the right of the screen. We have a section for quick adjustments, input selection, image section and general adjustments, practically all of them being important, especially the third one.

From the quick settings we can modify brightness, or activate its automatic mode, contrast and volume. Curiously, in the second section we have the PBP or PIP mode integrated in the monitor for when we have several sources connected, as well as the modification of the aspect ratio.

In the third section we find almost everything important, such as the image modes having a total of 8, the personalized image and color adjustment and the response time with three speed levels or disabled. In the last section we will have the general settings, such as the language, the energy saving mode, and little else.

It seems that we will not be able to modify the situation of the OSD nor do we have any gaming functions of any kind, being a fairly normal menu, although very easy to follow and manage.

User experience

After seeing practically everything the LG 34WK95U-W offers us, we reach the final stretch where we tell you about our experience with it and the final evaluations.

Multimedia and gaming experience

The nano IPS panel that has been used is good enough to give us a good gaming experience, since the color quality and the support for HDR are a good guarantee in this case. Obviously it is not a competitive gaming monitor, this is more than evident with its enormous resolution and its discreet frequency and response time.

We see it suitable for those users who want to have an experience in campaign mode at high resolution, for example, 3440x1440p with a high-end or enthusiastic level PC. At the end of the day 60 Hz is viable in 4K for RTX 2070 Super card and Radeon RX 5700 XT up.

We have not found almost any ghosting in fast and ultra fast mode, so it is perfectly valid and has sincerely surprised us in this regard, although you should expect a monitor of almost 1000 euros. Yes, we expected a better brightness due to its DisplayHDR 600 certification, but we have found a somewhat more discreet one. A positive aspect of its HDR imaging mode is that it offers good color balance without tending to overexposure of whites.

Design and work

We believe that it is its main strength and for what it is ultimately designed. For now, the Nano IPS panels are an almost exclusive option for design, for offering color quality and above all a very good fidelity to what our eyes see in reality, thanks to the filtering that the nanoparticle layer performs.

For a professional of both photographic editing and CAD design, the LG 34WK95U-W will come in perfect, due to its wide color coverage for the first case and the huge desk available in the second. Let's think that this type of creators use images at high resolutions and very wide scenarios for the design of plans and even simulations and rendering. Teaming up with an Nvidia Quadro will be a remarkable team.

The PIP and PBP modes will also give us great versatility in the case of having two or more computers connected, since it will facilitate the workflow with several users. Another element that comes in handy if we have a compatible laptop is the Thunderbolt connector, although it is true that 83W of power is not too much if the laptop has a dedicated graphics card, at least it will be enough to not worry about autonomy.

Perhaps in this aspect we have lacked a Pantone certification or something of the style, good enough to give us a Delta E less than 1 already from the factory. We believe that it would be a good guarantee for the almost 1000 euros that this team is worth. Not that it is bad, but we have seen that a colorimeter can work wonders, and not everyone has one of these devices.

The best of all has undoubtedly been the image quality, extremely precise, crystalline due to the pixel density and a flat panel that I sincerely like more than the curved one to work with. Something that seems important to note is that the panel does not present problems in the representation of characters as it did in the Ultra Wide of MSI with identical resolution and in other 4K and 3440x1440p. Here they look perfect for reading and editing even at very small sizes.

Final words and conclusion about the LG 34WK95U-W

We come to the end of this analysis where we have got to know in depth the LG 34WK95U-W, a monitor oriented mainly for design and professional and content creators.

Its main asset is the Nano IPS technology panel that it mounts, perhaps the most advanced technology in LCD type panels that gives it a very wide coverage with almost 99% in DCI-P3 and 5K2K resolution in an ultra panoramic flat format of 34 inches. Of course, due to lack of a desk it will not be, and also with a quite competent and useful 2x5W sound system.

The calibration has seemed good but not excellent, although it is true that it rotates at around 2.5 the average Delta, on a monitor of these characteristics and price a Pantone certification or previous hardware calibration would have been an extra for the user. However, the margin that the panel has is very large, dropping the average Delta practically to 0.5 without too much effort with a mid-range colorimeter.

We have also looked at the representation of the text and in this panel we did not find the sharpness problems that we did see in the MSI 5K2K panel, showing the text much smoother. Only the brightness seems to us to be improvable, since it is far from the specifications around 380 nits to the maximum.

The design has seemed very good, both in construction and in the choice of materials with a very minimalist appearance. Both base and support are made of aluminum, taking up little space at depth and giving us sufficient ergonomics to adapt the monitor in height and orientation. In addition, its small frames of only 10 mm make it have a large useful surface.

The connectivity is very good, since it does not give up HDMI, DisplayPort or Thunderbolt 3 ideal for working on laptops, since it also delivers 83W power. The PBP and PIP function are active for this monitor, as well as the possibility of managing it from the brand's own OnScreen Control software.

It is not a monitor optimized for gaming, but the truth is that it has very well controlled ghosting and it is something that we must highlight. It is normal to find 60 Hz at this relatively high resolution and response, but its support for HDR is a good option to consume multimedia and game content, as extra clear.

Finally, the price of the LG 34WK95U-W is about 930 euros, which for example is almost 100 euros less than the MSI Prestige PS341WU offering practically the same thing in every way. However for this price you could still refine a little more in the aspects discussed, but it is undoubtedly one of the best options in the price range.
