LG launches the world's first 4K monitor with AMD FreeSync support

LG has quietly unveiled one of the best AMD FreeSync-supported displays. The 27MU67 is a 27-inch 4K monitor that features variable refresh rate ranging between 40 to 60Hz. The goal behind FreeSync — which is similar to NVIDIA's G-SYNC — is to reduce latency and screen tearing, delivering frames as soon as they are pushed out by the GPU. Much like NVIDIA's offering, FreeSync works with compatible Radeon video cards.

As for the monitor, the 27MU67 features a 27-inch 4K IPS display with a resolution of 3840 x 2160, a latency of 9.7ms (5ms (GTG)) and maximum brightness of 300nits. The 10-bit panel displays 99 percent Adobe sRGB color space, and is calibrated out of the box. Connectors include two HDMI 2.0 ports, which can individually drive 4K at 60Hz, HDCP 2.2, one DisplayPort 1.2 port and a headphone out.

While pricing for the U.S. and European markets is unknown, the monitor is listed in Australia (opens in new tab) for AUD799, or the equivalent of $614, £399 or €565. Regional pricing will be revealed once the monitor goes up for sale in the U.S. and Germany starting next week.


Latest 4K Monitor Entices High-Level Gamers with Immersive Experience Delivered by 4K IPS Display and AMD's Free Sync

SEOUL, Jun. 9, 2015 ― LG Electronics will help gamers take their experience to a new level with the new LG 4K ULTRA HD monitor (Model 27MU67) which will be rolling out this month in select markets worldwide. The 16:9 aspect ratio 27-inch class monitor, which is specifically designed to provide a premium gaming experience, boasts a large viewing area and a 3840 x 2160 screen resolution for an eye-popping 4K visual experience.

LG's newest monitor is intended for the graphics-intensive visuals and fast-paced action of today's 4K Real-time strategy (RTS) and First-person shooter (FPS) games. The monitor supports AMD's FreeSync technology with a refresh range of 40-60Hz. FreeSync eliminates image-tearing and stuttering, which occurs when the monitor and graphics card are out of sync. The result is a smooth and seamless gaming experience, with fluid motion and no loss of frame rate.

The LG 27MU67 offers both In-Plane Switching (IPS) panel and Dynamic Action Sync (DAS) mode, reducing input lag to only 9.7 milliseconds, making it among the fastest 4K monitors on the market today. With the Game Mode hot key, users can individually customize the monitor's settings for each game to optimize the gaming experience. Black Stabilizer illuminates dark scenes and helps to clearly define the black areas where objects and enemies could be hidden. What's more, the Flicker Safe function lowers the risk of eye fatigue during marathon gaming or work sessions.

In addition to its gaming prowess, the 27MU67 excels at delivering excellent picture quality thanks to its 4K Ultra HD resolution that provides increased clarity, sharper texture and more details. The monitor's specially designed IPS 4K panels provide consistent color reproduction from almost any viewing angle and is capable of displaying over 99 percent of the sRGB spectrum to deliver more accurate color reproduction than the competition. LG's newest monitor offers both factory calibration and factory presets and is equipped with HDMI 2.0 input to support 4K resolution at 60Hz.

"A monitor with sharp picture quality, high field of view and less input lag is a must-have for today's serious gamers," said In-kyu Lee, senior vice president and head of the TV and Monitor Division at LG Home Entertainment Company. "The LG 27MU67 not only delivers on all counts, it is an excellent 4K Ultra HD monitor for professionals and non-gamers alike who want to design, edit or just watch movies."

The LG 27MU67 will be available starting next week at select retailers in the United States, Germany and Australia followed by its worldwide rollout. Details of availability and pricing will be announced locally.

  • Forget 4k, where are the paperthin OLED monitors we were promised fifteen years ago!
  • Price of OLEDs will keep them off the masses for a long time (except for smartphones). Now this 4k monitor is one of the cheapest around, and that is with no drawbacks in specifications, which is wonderful. But I still don't get why they chose to ship it with free sync, and not G-Sync!
  • Freesync is a royalty free tech which is adopted as official standard by VESA. So, expect many more displays in future with freesync.
  • It's not world's first..... Apple launched 5k monitor before
  • The world's first with AMD Freesync technology
  • Samsung announced their 4K Freesync models a long time ago. The release shouldn't be too far off.
  • Both Dell and HP have 27" 5K monitors also.
  • I think Apple slightly edges out the competition in the 5k space, simply because their 5k monitor includes a computer built-in for the price that others charge for just the monitor. That, and also because 5k won't be very viable on external monitors until Intel Skylake and Thunderbolt 3.0 are a thing.
  • On the iMac, you can't use the display as an external monitor, so you can only use the display with whatever components are inside.
  • I understand. That's because DisplayPort 1.2 (the current version) has limited bandwidth, most current 5k displays work by combing the feeds from two separate DisplayPort feeds. iMore did a good write up, and while it's obviously biased to support Apple, they bring up a good point: Until Intel Skylake and Thunderbolt 3.0 come out, there isn't enough video bandwidth to support connecting a 5k display without a workaround. So for me, personally, I fell people can wait a couple more months for a solution that will work significantly better than what's currently on the market today. Feel free to correct me where I'm wrong, but to my understanding: People are better off just using an iMac for now, or waiting until later in the year.
  • Very true, however very few thinks are 5k ready.  It would be cheaper to simply buy a samsung 4k 500 buck monitor and put more powerful hardware inside it vs the mac.  IMO that is.
  • I'm not disagreeing with you at all. The iMac only works because the inside has a custom built dual-DisplayPort thing going on inside, which is why it can't be used as an external display. Which, again, is why I mostly support just waiting for Skylake and Thunderbolt 3.0. We're only a few months away, and the impacts will be massive (Which is why I especially hope Microsoft releases a Surface Pro 4 or 5 around this time, using the new Skylake chipset, new hardware for Windows Hello, and charging via Thunderbolt 3.0). So many radical changes in the pipeline, Windows 10 and all these new technologies coinciding. Late 2015 and early 2016 will be ana amazing time to upgrade, especially for those stragglers who haven't bought a new machine since XP.
  • Indeed that would be best, my friend has the 5k iMac and it is a beauty.
  • 4k oled is pure bliss
  • What has this to do with Windows?
  • Filed under General News!
  • You can use it with your WINDOWS PC? Continuum? WINDOWS PHONE?   
  • Xbox too
  • Everything. This is a gamer monitor that you connect to your gamer PC running your gamer OS. And what is the gamer OS? Windows.
  • Price is ok.
  • 3840x2160 is UHD, not 4k.
  • Exactly
  • I thought UHD was just retailer speak to differentiate it from HD and Full HD.
  • Hugo's right... LG's marketing is playing everyone: "DCI 4K should not be confused with ultra-high-definition television (UHDTV) AKA "UHD-1", which has a resolution of 3840 x 2160 (16:9, or approximately a 1.78:1 aspect ratio). Many manufacturers may advertise their products as UHD 4K, or simply 4K, when the term 4K is traditionally reserved for the cinematic, DCI resolution.[3][4] This often causes great confusion among consumers.[5]"

  • I understand your point, that 4k should include at least 4,000 pixels, but in any consumer oriented application, 3840x2160 is EXACTLY 4k. 4k as a term in commercial use refers to the TV industry's doubling HD in each dimension (4x total) where HD is 1920x1080. 1920x2=3840 and 1080x2=2160. I know the Wikipedia page is with you and says otherwise, defining it as 4096x2160, and I'll yield to that information for the film industry, but it is nearly inconceivable that there will ever be any mass market 4096x2160 screens. There is no interest in forcing TV screens to get any more rectangular than 16:9. On the other hand, a quad HD display scales perfectly from existing HD TV's. That's the market.
  • There are already monitors that exist in a cinema scope aspect ratio. The sooner all tvs/monitors go that way the better.
  • 4K: 4096*2160
  • If this comes in at £399 I'll be grabbing one of these bad boys.
  • A 9ms response time? Isn't that kinda slow? My current 1080p 27" display has a 2ms response time.
  • 9ms black-to-black, 5ms gray-to-gray. At 120Hz, you've got 8.3ms per cycle, which would be a problem for high motion high contrast scenes. But at only 60Hz (top speed of this monitor when running 4k), the pixels only need to refresh faster than every 16.6ms to keep up with the display. There may be additional factors that others can weigh in on (e.g., maybe there's some electronics and other latency factors to add to this), but I'd say that anything under about 10-12ms for 60Hz is probably visually equivalent.
  • I will take the IPS 4K Asus ROG G-Sync over this once it finally ships.
  • Get it down to 250 and ill do three.
  • While that would be nice the bezels on this are way to fat, come on LG you have some great TEC use it.
  • That's one thing I never understood. Sooooo many people complain about monitor bezels, esp for gaming, yet there's so few thin bezel displays. Esp ones meant for gaming on. Mean while tvs are getting ever increasingly smaller. And I hear no one complaining about tv bezels ever.
