LG 34GK950F Front

Update: Reviewers have confirmed this monitor is also G-Sync compatible.

As it stands, the LG 34GK950F could be one of the all-around best gaming monitors on the market right now.

It’s currently the first monitor to come with a native 144Hz refresh rate at the 3440×1440 QHD resolution, compared to the G-Sync only version of this monitor (the LG 34GK950G) being limited to 100Hz naively (120Hz overclocked).

In addition to that, the LG 34GK950F also comes with LG’s amazing Nano-IPS panel with a wide 98% DCI-P3 color gamut, Radeon FreeSync 2, 1ms Motion Blur Reduction, and VESA DisplayHDR 400-certified HDR10 support. The HDR support is notable, since this feature is something lacking on the G-Sync sibling.

Being G-Sync and FreeSync combative, having HDR support, and a 144Hz refresh rate make this monitor the better of the two siblings for most. Oh, then you also factor in that it is $300 cheaper on average (currently).

Image Quality

LG is including its nano-IPS panel with this monitor, something that has been well received by gamers and reviewers alike. This technology is similar to Samsung’s Quantum-Dot technology, where it is able to reproduce more vivid and accurate colors when compared to traditional IPS technology.

LG explains this technology a bit on their press release for the display:

“Makes bright and dark portions of the image even more so, while Nano IPS controls color better, covering 98% of the DCI-P3 color space, the film industry standard.”

For most, the 3440 x 1440 21:9 UltraWide resolution will provide plenty of pixels to achieve a much clearer picture than standard resolutions. While not quite 4K resolution, this is just a tad below it.

This monitor ships with HDR400 support, so gamers can be assured colors and contrast will be the best possible from the game you are playing, something that is noticeably missing on it’s G-Sync sibling.

Reviewers have mentioned that IPS bleeding for these premium models is much-lower than most other cheap IPS panels.

Gaming Performance

The LG 34GK950F has a standard GTG input lag of 14ms, but this drops to 5ms in FreeSync “Faster” mode. Or, gamers have the option to use MBR (Motion Blur Reduction) mode, dropping the lag even further to an almost unnoticeable 1ms.

Unfortunately this cannot be paired to FreeSync mode, so you need to compare 5ms FreeSync to 1ms MBR and determine which you prefer. It’s also worth mentioning that using MBR mode reduces the screen’s brightness, so it may be more suited for dark-room gaming.

The screen provides an impressive 178° viewing angle, in case you are planning on using this monitor for any multiplayer gaming. This is notable since curved monitors suffer from lower viewing angles than any other screen type.

Standout Features / Design

As noted before, the LG 34GK950F’s highlight feature is its FreeSync 2 support allowing the monitor to allow faster input times and a variable refresh rate for AMD GPUs and Xbox One gaming consoles. This means the frame rate will be synced to whatever the GPU on the console or computer is able to push out at that moment (stutter free gaming).

The LG 34GK950F’s FreeSync variable frame-rate range is 55-144Hz, meaning if the GPU is unable to push out more than 55FPS (for lower end GPU’s or intensive games), it will ensure you still experience smooth gameplay.

Other notable features this monitor comes with are Dynamic Action Sync, picture-presets (etc. gaming mode vs work mode), and Black Stabilizer (see enemies better in the dark).

It’s also worth mentioning the LG 34GK950F comes calibrated for the best picture straight out of the factory. While not everyone agrees with these settings, it’s nice that LG does this for their gaming monitors compared to their Home/Business monitors.

View / Ports

LG 34GK950F Rear

Because 144Hz at 3440×1440 (1440p) requires DisplayPort 1.4*, that’s what this monitor ships with, unlike the G-Sync model which comes with 1.2. The LG 34GK950F also has two HDMI 2.0 inputs, two USB 3.0 ports, and a headphone jack.

*Please note that your computer’s GPU output needs to support DisplayPort 1.4 to run 3440×1440 at 144Hz. If your GPU only has a DisplayPort 1.2 port, you will be limited to 3440×1440 and 120Hz.


The LG 34GK950F ranks in many of our lists as one of the best gaming monitors you can currently buy, for many reasons. It has a fantastic nano-IPS screen, the color coverage and accuracy is superb, and the included FreeSync and G-Sync support make this monitor perfect for most gamers.

The LG 34GKG950F is as good as it gets from LG – this is currently the best gaming monitor you can buy from them. For those looking for a dual FreeSync/G-Sync monitor, this is among the best monitors you can buy of any brand. With many features omitted from its G-Sync sibling monitor, the LG 34GK950G, many gamers will opt for this monitor instead.
