The LG 27GK750F is a rapid 27″ 1080p 240Hz 1ms TN gaming monitor with FreeSync and MBR. However, nowadays you can find an equally fast IPS variant at the same price.
Looking for a 240Hz gaming monitor with backlight strobing for the smoothest fast-paced gaming performance? Let’s see how the LG 27GK750F stacks up.
As expected, in order to get the best performance out of something, you’ll have to sacrifice something else – in this case, the picture quality.
The LG 27GK750F monitor is based on a TN panel with a 400-nit peak brightness, a 1,000:1 static contrast ratio, 160°/170° viewing angles, 1080p resolution, and 8-bit color depth for 16.7 million colors.
You can find almost identical specs in ~$100 budget monitors, so keep in mind that you won’t be quite blown away by colors, details, and viewing angles of the LG 27GK750F.
However, if you’re a serious gamer, you won’t mind all that as in return, you get a rapid 240Hz refresh rate and quick response time.
As far as the resolution is concerned, 1080p may be low for most users, but if you want to reach anywhere near 240 FPS (Frames Per Second), a lower resolution is preferred anyway.
Lastly, the 27″ screen of the LG 27GK750F 240Hz monitor is fairly large for 1080p, which results in a low pixel-per-inch ratio meaning that the picture will be somewhat pixelated.
But there’s a silver lining here as well. Because the image is so pixel-y, everything will be larger, which can raise your precision in FPS games.
Alternatively, you can get a smaller 24″ or 25″ 240Hz monitor with clearer image quality. The advantage with smaller screens is that you won’t have to move your eyes/head as much as you would with a larger 27″ screen.
The LG 27GK750F has an advertised response time speed of 2ms (GtG) in the ‘Fast’ overdrive setting. This option, however, introduces pixel overshoot (inverse ghosting).
There are four overdrive options: Off, Slow, Normal, and Fast.
Using the ‘Normal’ setting, the pixel transition time is quick enough to keep up with the 240Hz refresh rate, and it doesn’t introduce overshoot, which is why we recommend using this option instead of ‘Fast.’
The LG 27GK750F input lag performance is top-notch as there are only ~3ms of delay, which is imperceptible even by high-end professional gamers.
While the jump from 144Hz to 240Hz isn’t as noticeable as going from 60Hz to 144Hz, it’s definitely impactful – given that your GPU/CPU can output adequately high frame rates.
So, if you’re still on a 60Hz display and on the fence between 240Hz and 144Hz, we recommend getting a 144Hz gaming monitor and spending the rest on upgrading your PC system.
In case you don’t need to upgrade your PC or just want the best motion clarity and responsiveness in competitive games, 240Hz is definitely the way to go.
Additionally, the LG 27GK750F boasts the 1ms Motion Blur Reduction (MBR) technology. This feature uses backlight strobing to decrease perceived motion blur.
It only works at select fixed refresh rates, including 120Hz, 144Hz, and 240Hz. For the best results, your frame rate should be on par with the set refresh rate.
Note that enabling this feature also lowers the display’s maximum brightness (from 400-nits to ~200-nits) while it’s activated. So, use this feature only when playing fast-paced video games.
Alternatively, you can use AMD FreeSync if you have a compatible AMD graphics card. FreeSync will make the display change its refresh rate dynamically, which entirely removes screen tearing and stuttering with only minor input lag penalty (~1ms).
However, FreeSync only works within a specific FPS/Hz range, which in this case, amounts to 48-240Hz. Note that you cannot use FreeSync simultaneously with 1ms MBR.
FreeSync also works without any issues when using a compatible NVIDIA G-SYNC graphics card as the LG 27GK750F is certified as G-SYNC Compatible.
Other gaming features include customizable crosshairs, picture presets (two FPS, one RTS, and two customizable modes), Black Stabilizer, which increases the visibility of objects in dark surrounding in video games, and Dynamic Action Sync which causes the monitor to bypass certain image processing for minimal input lag.
Design & Connectivity
Connectivity options are abundant and include DisplayPort 1.2, two HDMI 2.0 ports, a dual-USB 3.0 hub with fast-charging and a headphone jack.
The matte-black design offers versatile ergonomics including 100x100mm VESA mount compatibility, up to 110mm height adjustment, 90° pivot, tilt and -/+ 20° swivel.
Price & Similar Monitors
The LG 27GK750F price amounts to around $330.
At this price, we highly recommend the ViewSonic XG2431 instead. It has a 24″ IPS panel that’s just as fast, but has better colors and wider viewing angles. Moreover, it has an exceptional backlight strobing implementation.

All in all, the LG 27GK750F is an excellent monitor for competitive gaming, but there are better options available at the same price range.
