LG 34GK950G Front

The LG 34GK950G is proving itself to be one of the top G-Sync monitors on the market right now.

Like it’s FreeSync sibling monitor (the 34GK950F), reviewers are making it clear that the UltraWide QHD nano-IPS panel these monitors come with make your gaming experience the best money can buy.

While the refresh rate is slightly less than on the FreeSync version because of software limitations – it seems possible this can be updated in a future firmware update of NVIDIA’s G-Sync module, since this is the thing holding it back. It shares the same panel as its FreeSync sibling, meaning the panel is capable of a slightly higher refresh, at 144hz. LG has not stated whether this will ever happen, since it relies on NVIDIA to update the G-Sync module – so don’t hold your breath.

Aside from a slightly lower refresh rate, the G-Sync does come with the extra feature of sphere backlighting to entice buyers who may feel disappointed.

The LG 34GK950G will try to beat the established competition with its beautiful nano-IPS display, but its overall performance and extra features will determine whether or not that will happen.

Image Quality

The LG 34GK950G comes with a 34-inch nano IPS panel with a native 3440 x 1440 resolution, maximum 120Hz refresh-rate and ultra-fast pixel responsiveness of 1ms with G-Sync MBR (Motion Blur Reduction) mode on. The monitor supports only 120Hz in overclock mode, but the G-Sync module forces the monitor to work at 100Hz with overclocking at 20Hz with the controller.

To confirm what we have noticed when viewing this display, reviewers from Amazon are mentioning fantastic colors and excellent color uniformity, something that is notable for curved displays. Color representation on a curved panel is important, since we have seen other curved displays have issues with the panel giving a “rainbow effect” during normal viewing.

Gaming Performance

There have been many fast-refresh UltraWide monitors from LG in recent months, including the FreeSync version of this monitor, the native-144Hz UltraWide QHD 34GK950F.

The current version of the integrated G-sync module only supports 100Hz natively at the full resolution of the monitor. Even though the installed IPS panel can technically support a higher refresh rate, the G-sync module is what’s holding it back. LG very kindly has enabled support for 120Hz mode using the monitors overclocking feature, since technically for the G-sync module, this is above what it can support from a software standpoint.

From the panel’s perspective, it should have no trouble keeping up since it’s still below the native 144Hz it can cope with (like on the FreeSync version of this monitor). Unfortunately it cannot be overclocked more than 120Hz currently, because the v1 G-Sync module only supports DisplayPort 1.2, which can’t handle the heavy data needed to reach 3440 x 1440 @ 144Hz. Who knows if they will update this in the future.

Standout Features / Design

The 34GK950G is very similar to the 32GK850G in terms of design aesthetics, with the exception of the UltraWide display at a 21:9 ratio, which determines its considerable width.

This monitor will be supplied in black with several red accents on some parts. It comes with a cool RGB LED circular strip light neatly integrated into the back of the display.

Players will be able to customize this “Sphere Lighting”, as LG calls it, to match an array of different colors and lighting modes to enhance the gaming experience. This includes matching the colors being displayed with the rest of your gaming PC’s colors via software, to provide an immersive gaming experience.

The face has a frameless, thin-bezel design, which is made possible by a two-stage application consisting of a thinner outer layer and an even smoother inner edge. The front of the screen is matte finish which helps provide easier daytime play, even if it comes at the expense of giving darker blacks.

View / Ports

LG 34GK950G Rear

There are many ports on the back of this monitor, including a DisplayPort 1.2, two HDMI 2.0 ports, two USB 3.0 ports with fast-charging capability, and a headphone jack.


The LG 34GK950G is a great example of how LG continues to push the gaming market forward with beautiful and unique displays. We can thank LG for pushing the gaming scene towards curved, ultrawide and even 4K monitors. Even though it was not the company’s first ultrawide curved monitor, it has pushed the capabilities as far as possible to apply such a beautiful display towards a gaming audience.

While even 2 years ago, we only saw curved ultrawide monitors catering towards the graphic artist and editing community, its nice to see this technology being adapted with gamers in mind. I have no doubt many people will prefer these monitors to the flat-panel ones.

In short, the LG 34GK950G is a fantastic offering for being the G-Sync varient of this UltraWide monitor. With colorful features, a truly beautiful screen, and solid build quality, it can easily surpass many of its G-Sync competitors. Out of the box, the screen may require a bit of tweaking to make it comfortable for your gaming preference, but after tuning; the product easily becomes one of the best in its segment.
