LG 27GK750F Front

LG has climbed from being a lesser-known brand in computer monitors just 10 years ago, to now being one of the leaders in making home and business monitors in America.

While LG first started out targeting the home and business monitor display market, the LG 27GK750F is a great example of the company pushing its bounds to expand into other areas it thinks it can dominate also.

The LG 27GK750F is a great example of a product pushing the boundaries for what gaming monitors are capable of. As one of the first 240Hz monitors to hit the market, this product is aimed clearly at professional gamers who have powerful enough computers to push the maximum 240 FPS (frames per minute) limit of this display.

We have seen LG make great strides as a display company, with other products of theirs such as the X and X being rated as some of the best gaming monitors you can currently buy. As you will see in this review, LG continues to lead the pack with its release of the 27GK750F.

Image Quality

The LG 27GK750F comes with a 27”, 1920×1080 (Full HD) TN panel. This may not sound like much, considering you can find other 27” displays with this resolution and panel for next to nothing. But the technology of this display really shines when it comes to the refresh ratio; a whopping 240Hz.

This is a very new technology in monitors, with the first production 240Hz display for gaming only having shown up in 2015.

The LG 27GK750F display is a TN panel, which are not known for their color vibrancy, brightness or contrast ratio. Where they lack in some areas they make up for in uniform brightness, low light bleed for blacks, and very fast response and refresh times.

The particular TN panel that comes on the 27GK750F monitor comes with a peak 400 nits of brightness (pretty good), 1000:1 contrast ratio, max 170° viewing angle and 8bits of color (16.7mil colors). Considering this is a TN panel, these specs are pretty good, and you can thank LG for trying as hard as they could to bring the colors and brightness up to decent levels.

We have seen TN panels that look so bad it’s like it has a permanent grey-filter over the screen – and this monitor is far from that. Scroll down to the reviews to see consumer pictures for a good idea of color representation.

Gaming Performance

If the display is not adequate for some, just combine this fact with how the display has an input lag time of only 2ms (GTG w/FreeSync), or 1ms with MBR (Motion Blur Reduction) mode, and things really start to take shape why this monitor has so much potential as a pro gaming display.

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).

Keep in mind, the 2ms FreeSync response time is in the display’s “Fast” response setting, which some customers have stated can introduce inverse ghosting issues. This could appear as a white-ish trail left behind fast moving objects. It’s unclear if LG has plans to fix this in a future software update, but the current remedy is using “Normal” mode for the overdrive setting.

At this “normal” setting, the responsiveness is still fast enough to keep up with 240 frames per second, and doesn’t run into any stuttering issues some may suspect could happen.

Standout Features / Design

Some other notable features of this display include customizable crosshairs, Black Stabilizer mode (increases visibility of objects in dark scenes), and DAS (Dynamic Action Sync) mode, which cause the monitor to bypass certain image processing for minimal input lag. DAS has been proven to have minimal effect when in FreeSync or MBR mode, however.

Also worth mentioning is the display having a picture preset feature, allowing two FPS (First Person Shooter) settings, one RTS (Real Time Strategy) setting, and two completely customizable settings.

Design on the LG 27GK750F is minimal, yet aggressive – letting you know it is clearly a gaming monitor. We personally are fans of aggressive design on gaming products, it’s nice to have a visual reminder your computer/monitor is capable of something extra fast. Sort of like why a Lamborghini doesn’t look like a Saturn.

View / Ports

LG 27GK750F 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 27GK750F is a great example of how LG continues to push the gaming market forward with beautiful and capable displays. Even though it was the brand’s first 240Hz monitor, it was proven a capable contender for those seeking the fastest refresh monitors currently for sale.

We do wish the resolution were just a tad higher for a 27” display to future-proof this display for more powerful GPU’s eventually. That being said, I’m sure this monitor will serve as one of the youngest leaders in pushing the entire gaming industry to hyper-realistic 240 FPS refresh-rates in our near future.
