The LG 27GP950-B is a 27 inch 4k monitor with a fast 160Hz refresh rate. It's part of LG's UltraGear lineup of gaming monitors and is one of the first monitors on the market to support HDMI 2.1 bandwidth, making it a great choice for next-gen console gamers. It delivers an excellent gaming experience with low input lag, a fast response time, and support for both NVIDIA and FreeSync Premium Pro variable refresh rate technology. Unfortunately, it has disappointing reflection handling, and like most IPS monitors, it's not a great choice for a dark room, as it has low contrast and poor black uniformity. It also has a local dimming feature, but it doesn't do much to improve the picture quality.

Our Verdict

8.1 Mixed Usage

The LG 27GP950 is a great monitor for most uses. The large, high-resolution screen is great for office use or media creation, and it has a superb color gamut in SDR and incredible gradient handling. It's an excellent gaming monitor with low input lag and a fast response time. It's also decent for HDR, with a wide HDR color gamut and high peak brightness, but blacks look gray in dark rooms.

Pros
  • Image remains accurate at an angle.
  • Low input lag.
  • Great peak brightness.
Cons
  • Disappointing reflection handling.
  • Low contrast and poor black uniformity.
8.2 Office

The LG 27GP950 is a very good monitor for office use. The high-resolution screen delivers outstanding text clarity, and it has excellent gray uniformity. It has wide viewing angles, great if you often share your screen, but the stand can't swivel.

  • HDMI 2.1 for next-gen console gaming.
  • Low input lag.
Cons
  • Disappointing reflection handling.
  • Low contrast and poor black uniformity.
7.6 Media Consumption

The LG 27GP950-B is a very good monitor for watching videos. The large, high-resolution screen delivers a more immersive movie-watching experience, and the wide viewing angles are great for watching videos with a few friends. Unfortunately, it doesn't look as good in a dark room due to its low contrast ratio and poor black uniformity.

Pros
  • Good gray uniformity.
  • Low input lag.
  • Great peak brightness.
Cons
  • Disappointing reflection handling.
  • Low contrast and poor black uniformity.
8.3 Media Creation

The LG 27GP950 is a great monitor for media creation. The large, high-resolution screen makes it easier to see more of your workflow at once, and the wide viewing angles are great if you often share your screen.

The LG UltraGear 27GP950 has a very similar style to the other 2021 LG UltraGear monitors. The chevron-shaped stand is pretty wide but doesn't take up a ton of space, and it supports the monitor fairly well. There's a ring of RGB bias-lighting on the back of the monitor, which can be synced with video or audio playing on your PC.

Build Quality

The LG 27GP950 has decent build quality overall, very similar to the other UltraGear monitors we've tested. It's almost entirely plastic, and there's some flex on the back, but nothing concerning. The stand is fairly stable, but as you increase the height extension there's more and more wobble.

The LG 27GP950 has decent ergonomics. It has a good height adjustment and an okay tilt range, so you won't have trouble placing it in an ideal position unless you need to turn the screen as it doesn't offer swivel adjustment. Also, you can only rotate to portrait orientation in one direction, so the inputs will always be on the top.

The back of the monitor is pretty plain overall. There's a ring of RGB bias-lighting, which LG calls Sphere Lighting 2.0. You can sync the lighting with audio or video from your PC. You can also customize it yourself through LG's software or the physical wheel on the bottom of the monitor. There's a ring of vents around the bias-lighting ring, and there's a fan built-in, which is quiet. There's a hook on the back of the display for cable management, but it's not very effective overall.

As expected for an IPS monitor, the LG 27GP950 has mediocre contrast, and blacks look gray in a dark room. Unfortunately, the local dimming feature is ineffective at boosting contrast with our checkerboard pattern due to the large zone size.

Unfortunately, although the LG 27GP950-B has a local dimming feature, it's terrible. It has about 16 zones, so each zone covers a relatively large area of the screen. Due to the large size, any object on the screen causes an entire column of the screen to light up, resulting in significant blooming. With most real content, this isn't that noticeable, as all zones are usually lit up. On the other hand, there's absolutely no black crush, with no loss of fine details in some scenes.

The speed of the local dimming feature can be adjusted between three different settings. We did our testing with it set to 'Faster', as this mode delivers the best results with fast-moving objects, but the zone transitions are quite noticeable and can be jarring in some cases. Lower settings average out the backlight across more zones, so this isn't as noticeable, but the local dimming feature isn't as noticeable or effective then.

The LG 27GP950 has great peak brightness in SDR, and it's bright enough to overcome glare in most bright rooms, despite its disappointing reflection handling. Unfortunately, with local dimming enabled the monitor dims our 25% window briefly. This isn't noticeable with regular content, and even with the test pattern, it returns to normal quickly. With local dimming disabled, there's almost no variation in brightness with different scenes or over time, and all scenes are around 400 cd/m². Sadly, its minimum brightness is high, which isn't ideal if you want to use it in a completely dark room and you're sensitive to bright lights.

These measurements are from after calibration in the 'Gamer 1' Picture Mode with Brightness set to max, and Local Dimming set to 'Faster'.

The LG 27GP950-B has great peak brightness in HDR. It's bright enough to deliver an impactful gaming experience in HDR, and it's bright enough for some video content. However, it can't maintain a high brightness level with large, bright scenes, and there's a significant decrease in brightness over time. The EOTF follows the target PQ curve perfectly until the peak brightness, where there's a slow roll-off, so you don't lose too many details in bright highlights.

These measurements are in the 'Gamer 1' Picture Mode with HDR enabled, Local Dimming set to 'Faster', and Brightness set to max.

The LG 27GP950-B has excellent accuracy out of the box. It has an sRGB mode that clamps the colors to the sRGB color space, so they're not over-saturated, and most colors are accurate. The white balance is a bit more off though, which affects the shades of white and gray. The color temperature is cold, giving the image a blue tint, and the gamma isn't the best as most scenes are darker than intended. The sRGB mode locks most picture settings, and if that bothers you, you can use the Gamer 1 Picture Mode, but that results in a less accurate image as the colors are too over-saturated and the color temperature is even colder.

The LG 27GP950-B has outstanding accuracy after calibration. Gamma follows the sRGB gamma curve well, but some scenes are still a bit off. Colors and white balance are nearly perfect, and any remaining issues aren't noticeable without a colorimeter. Unlike the vast majority of monitors, the 27GP950-B supports hardware calibration through LG's Calibration Studio, so you can get an accurate image from any source, even if the source doesn't support ICC profiles.

The LG 27GP950 has an excellent response time at the max refresh rate of 160Hz. Like most monitors, the pixel overdrive can be adjusted, and the best setting is 'Fast'. It has a quicker total response time than 'Normal' and much less overshoot than 'Faster'. It still does have overshoot, and 'Normal' is better at lower refresh rates, so if you want a 'set an forget' mode, use 'Normal'.

The LG 27GP950 has remarkably low input lag, resulting in a very responsive gaming experience. We encountered a strange issue during testing. For the overclock to work properly, Adaptive Sync has to be enabled in the OSD and on your PC. With VRR disabled on the PC, the monitor appears to actually be running at 80Hz and doubling every frame. This issue is only noticeable at the max refresh rate, even with the overclock enabled. The issue isn't there at a lower refresh rate, even if the overclock is still enabled. Running the overclock with VRR disabled causes the input lag to increase to 7.8ms.

The LG UltraGear 27GP950 has two HDMI 2.1 ports that support the full bandwidth HDMI 2.1 of 48 Gbps. It has even higher bandwidth than some other HDMI 2.1 monitors like the Gigabyte M28U, so you can use any HDMI 2.1 compatible graphics card to achieve high-frame-rate signals, and you won't have to worry about whether or not it supports compression. This is particularly an advantage for PS5 owners because the console doesn't support compression, so it displays chroma 4:2:2 signals instead of 4:2:0, which results in clearer text.

When connected with a recent Mac computer, the LG 27GP950-B has a max refresh rate of 144Hz, but it can't be overclocked to 160Hz. There aren't any issues with the VRR and HDR support, and when you're not gaming and still have the VRR support enabled, the refresh rate stays at 144Hz. When waking up a MacBook from sleep, sometimes the windows would all move to the laptop, and other times it would stay on the monitor. Also, the default resolution is 1920 x 1080, so you need to adjust it to get a 4k resolution.

The LG 27GP950 has a very similar interface to the other LG monitors we've tested recently. You can navigate most of the on-screen display using the joystick located under the bottom bezel of the monitor.

There's also a wheel controller that you can use to adjust the backlight setting. Note that some of the backlight settings require the LG Ultra Control Center software on your computer, and the monitor must be connected to your computer with the USB upstream cable (included) for the control software to work.

Differences Between Sizes And Variants

We tested the LG 27GP950-B 27 inch gaming monitor, which is part of LG's UltraGear gaming lineup and is the only one with HDMI 2.1. There are many other monitors in LG's UltraGear lineup with various configurations, some of which you can see in the table below. As they each have different specs, we don't expect our review to be valid for any of the other models.

Model Size Panel Type Resolution Max Refresh Rate
34GP950G 34" IPS 3440 x 1440 180Hz
34GP83A-B 34" IPS 3440 x 1440 160Hz
32GP850-B 32" IPS 2560 x 1440 180Hz

If someone comes across a different type of panel or their LG 27GP950 doesn't correspond to our review, let us know and we'll update the review. Note that some tests, like gray uniformity, may vary between individual units.

Our unit was manufactured in July 2021; you can see the label here.

Compared To Other Monitors

The LG 27GP950-B is an impressive gaming monitor, and one of the few currently available that support HDMI 2.1, making it an especially great choice for console gamers. It doesn't stand out much for PC gamers, though, so if you're not interested in console gaming, there are better choices available.

Check out our recommendations for the best gaming monitors, the best monitors for Xbox Series X, and the best monitors for PS5.
