A Review of the LG 27MU67-B 27″ Class 4K UHD IPS LED Monitor – 27MU67
LG is no stranger to assembling some absolutely excellent display screens, whether they be in TVs, smartphones or PC monitors, and the LG 27MU67-B 27" Class 4K UHD IPS LED Monitor is no exception to this tendency. While certainly not the finest 4K PC display on the market and perhaps not up to the standards of certain fully professional displays, the 27MU67-B nonetheless delivers some truly outstanding features that make it into a 4K display almost worthy of being classified as a pro model.
An IPS display, excellent color gamut coverage and some interesting workspace enhancement technologies are also promised in the 27MU67-B and combine together to deliver a monitor that looks like an all-around solid, if not excellent piece of 4K PC display technology for both casual use and professional work needs.
Furthermore, while not having the much faster response times of a TN display, the IPS panel design of the 27MU67-B 27" does include both excellent display color and AMD FreeSync technology for a more robust 4K PC gaming experience similar to the Samsung U28E590D.
LG doesn’t always get its display technology just right and some of their older 4K TVs (pre-OLED) are downright disappointing to behold but this isn’t the case with the 27MU67 27". Here, the company offers one very interesting gaming and graphics work tool.
The LG 27MU67-B 27" comes loaded with goodies that promise some superb visuals and gaming quality specifically. This is a monitor that has been built with a semi-professional grade of display specs that make it rather useful for graphic design work and PC gaming at 4K resolution as well.
To start with, there is the combination of IPS display technology and an sRGB coverage of more than 99%. This means a maximum of picture clarity with color accuracy and color at minimal levels. The extremely high sRGB and CMYK color gamut range coverage in the 27MU67-B 27" ensures some very high realism and vibrancy to the colors on the screen, while the IPS panel means that contrast, vibrancy and clarity stay high even at off-center viewing angles. For this reason, the 27MU67-B 27" is a particularly useful model for designers who want to edit photos and graphics without spending more than $1000 on professional-grade 4K monitors.
Next, there is AMD’s FreeSync technology, which has been built into the 27MU67-B’s DisplayPort 1.2 settings. AMD FreeSync --designed to work with higher-end AMD gaming GPUs and particularly the company’s 4K-ready gaming GPUs—is designed to minimize tearing and stuttering on the screen by synchronizing display frame rates with those of your PC’s graphics card. The result is fluid movement even at heavy gaming resolutions and settings. FreeSync in the 27MU67-B puts this specific model a high cut above most 4K PC displays as a choice for 4K and even HD gamers.
To top things off even further with the gaming chops of the 27MU67-B, there is also a built-in Game Mode that LG has included with the monitor. Three programmed gamer modes exist in the 27MU67-B. Two of them are first-person shooter modes and a third is an RTS pre-set option for choosing something a bit more flexible. Some gamers not like any of the three modes but they do offer some cool optimized features and their inclusion shows that LG is definitely aiming at the gaming market as well with this particular monitor.
Finally, there are four screen split and Dual Link Up features built into the 27MU67-B with an eye to creating an optimal digital workspace experience. The four screen split is a big booster on productivity and by now a rather common feature in 4K monitors. It can be activated from a drop-down menu list by simply re-sizing your screen to any one of 8 pre-configured screen splits that break down into anywhere from 2 to four windows for whatever scenario and work arrangement you need. As for the Dual Link Up, it allows you to connect two different compatible devices like phones, cameras, Blu—ray players and other computers to the same monitor and use both in their own separate screen at the same time. However, the Dual Link Up must be used with one DisplayPort connection while the other device connects via HDMI.

The 27MU67 from LG is of course also far from perfect and a few notable deficiencies are worth mentioning, though none of them are serious enough to warrant ignoring this monitor.
First of all, there are no USB ports on the 27MU67. This is a bizarre and gross oversight on the part of LG and while yes you do get dual HDMI, Display Port 1.2 and mini Display Port 1.2 ports, USB is a crucial extra that a lot of users wouldn’t want to go without.
Secondly, the IPS panel, while excellent for visual quality does also mean a slightly slower response time when it comes to PC gaming controls. Furthermore, it adds to the price of this monitor just enough to make it slightly more expensive than other models with the same specs that we’ve seen on the market.
Finally, the 300cd /m2 brightness level of the screen isn’t actually quite that high in practice, registering somewhat less at 290 cd/m2 or below in some cases. While this will be fine for most users, there are cheaper 4K PC monitors that come with superior 320 or 350 cd/m2 brightness ratings.
The LG 27MU67-B 27" Class 4K IPS Monitor is a solid piece of 4K PC display technology but its only excellent feature is its display color quality. Connectivity is below average and the physical design lacks adjustability options. That said, we do recommend it for PC gamers since it comes with AMD FreeSync and this is still a less than common spec in many 4K monitors.

The main highlights of the LG 27MU67-B revolve around its FreeSync technology and array of work-enhancement additions.
The FreeSync technology was a real bonus in the 27MU67-B. This feature is designed to work with AMD’s higher-end and 4K-capable gaming GPUs and if our PC happens to have one of these, then this is a monitor that’s definitely worth considering. FreeSync synchronizes the frame refresh rate of the 27MU67-B with that of your PC’s GPU to create a much smoother gameplay and video viewing experience which is free of tear, juddering and stutter. This is particularly useful technology for anyone who wants to use the 27MU67-B for gaming at 4K resolutions. It might cause your monitor to show a slower frame rate as it adjusts itself to the refresh rate of your GPU but your general gameplay experience will definitely flow more smoothly.
FreeSync only works with AMD GPUs and must be used through the 27MU67-B DisplayPort 1.2 connections, so bear this in mind since the monitor comes with only one DP 1.2 and one Mini DP 1.2 port.
Moving along, we have to say that the work- enhancement technologies in the 27MU67-B are very useful for professional tasks that require a bit more efficiency and flexibility. The four screen split technology offers enough different screen splitting options for anywhere from 2 to four screens that it is genuinely interesting to work with, particularly for projects that require comparative tasks. Likewise applies for the Dual Link Up feature. By letting you connect two different PCs or other devices to the same 27MU67-B monitor, Dual Link Up can be a useful tool for working on projects from two different PCs at the same time –or from a PC and a tablet or smartphone or even an external media player.
Finally, the physical design of the LG 27MU67-B is worth mentioning. This is a good looking piece of technology with a robust black body and a sturdy design. However, while pivot and height adjustability is there, the display can’t be rotated or tilted and this is a bit disappointing.

Thus, LG’s excellent reputation for high performance and clarity at 4K and high definition in general is further reinforced with the 27MU67-B thanks to a powerful, vibrant and highly realistic color spectrum on the screen. The 99.5% sRGB coverage is further combined with a high level of CMYK color range coverage to offer 10 bit color that shows 1.07 billion different colors for maximum accuracy. No, you’re not getting the same absolutely superb professional color coverage you might find in select pro 4K monitors for visual editors, and the 27MU67-B doesn’t come with a certified AdobeRGB coverage, which is a telling sign that this isn’t a true professional 4K display. However, what you do get in terms of color accuracy and range is more than great for the price at which this display is selling.
The IPS panel technology only improves things further by introducing maximum brightness, clear and wide 178 degree clear off-center viewing angles.
Finally, LG has included a “Black Stabilizer” feature that actually works to increase brightness during gameplay in darker scenes. This can be deactivated but it’s rather amusing to see it included when one considers that most display devices today want to promote exactly the opposite: how deeply dark they can make their on-screen dark spaces. Black Stabilizer aside, the contrast level of the 27MU67-B is decent. It’s not superb or as good as some PC monitor contrast levels we’ve seen but it’s also not so bad that it might cause serious annoyance.
The connectivity of the LG 27MU67-B can best be described as just below average and is in fact one of this monitor’s weakest aspects. You do get most of the modern basics via two HDMI 1.4 ports, a DisplayPort 1.2 port and a Mini DisplayPort 1.2 port but the lack of USB ports of any kind is a major defect of the model and the HDMI could definitely have been of the 2.0 variety for more options for connecting external 4 video sources at 60 frames per second. This is a relatively new 4K monitor after all.
The FreeSync technology of the 27MU67-B can only be used via the monitor’s DisplayPort 1.2 connection.
The price of the LG 27MU67-B is sitting at $519.45 on amazon.com. This isn’t a bad price for the display quality of this monitor but neither is it particularly great considering the weak connectivity features. The more professional version is the LG 31MU97-B.

To summarize briefly, the LG 27MU67-B suffers worst from a lack of serious connectivity options and the exclusion of HDMI 2.0 and USB ports is a major deficiency here. That aside, the contrast levels on the screen could have been a bit better and LG could also have included better stand adjustability options.
