LG 27GN950 Review: Best 4K 144Hz IPS Monitor?


The LG 27GN950 is a new monitor from the technology powerhouse brand. While it’s catered towards gamers, this 4k IPS monitor performs well at just about everything. There’s a 144Hz refresh rate, 1ms response time and G-SYNC compatibility.

Additionally, this monitor has vibrant and accurate colours. If you’re someone who needs proper colour management, this might be a great choice for you. There’s also decent HDR picture quality with DisplayHDR 600 certification.

Lastly, the LG 27GN950 has a really fantastic design that makes it stand out from the crowd. It’s got a 4-side borderless design and RGB lighting technology – another touch catered towards gamers. But is it worth the $799.99 price tag?

Image Quality

LG’s Nano IPS panel is known for its fantastic quality, and is praised by reviewers consistently. With 1ms GtG pixel response time speed you’re unlikely to have any ghosting. Plus, the DCI-P3 color gamut (equal to about 135% sRGB) really brings colors to life. It’s incredibly rich and will wow you.

However, it can make things appear over-saturated at times, but that’s not an issue for general use or DAW software. There’s also an included sRGB color gamut clamp which provides a more accurate color reproduction.

During a quick Adobe Photoshop session, the colors appeared consistent and accurate in comparison to other benchmark screens. The included LG True Color Pro app also allows you to tweak things to your liking.

The monitor has a 178° wide viewing angles, so even viewing this screen from the side, the image looked crystal clear. In a music studio, it’s great if you have a bunch of people standing around looking at the session. It’s got a 400-nit peak brightness and a static contrast ratio of ~1000:1

With HDR content, there’s a 600-nits peak brightness, providing intense and vivid highlights. As mentioned, there’s VESA’s DisplayHDR 600 certification. Just make sure you use the appropriate cable. This wasn’t tested thoroughly, and the mileage seemed to vary.

The 4K UHD resolution provides a high pixel density of 163 PPI (pixels per inch) on the 27” screen. For day-to-day use, you’ll most likely have to scale things up in order to make things like text readable. However, in DAW software the additional resolution is a pleasure.


The LG 27GN950 has very minimal input lag and quick response time. As someone who isn’t a gamer, this was a nice touch, however it didn’t really matter too much. Watching media looked absolutely unreal.

If you’ve ever used an IPS panel before, you’ll know that IPS glow is an issue. In a dark music studio, it shouldn’t be problematic, however it is slightly noticeable in the bottom corners. IPS glow kind of looks like some parts of the screen are “glowing” – however it really has to do with the angle you are looking at.

To add, the LG 27GN950 uses a flicker-free backlight and has an integrated low-blue light filter, which is great when you’re in the music studio for long hours.

Monitor Features

This monitor has a bunch of nifty features. You can either use the on-screen keys or desktop application to control the monitor settings.

There’s also a small wheel on the monitor to control the 48 RGB LEDs located on the back of the monitor. It adds a pretty cool touch to any computer room or music studio. There’s a bunch of settings for this too – including synchronizing the lighting to music.

Design & Connectivity

The LG 27GN950 display is definitely a unique monitor to look at. It features a 4-side borderless design, unlike most monitors which have only a 3-side borderless design. There’s no branding on the front.

While the monitor provides a decent amount of pivot, and can also be VESA mounted, it’s unfortunate that you can’t swivel the monitor right and left.

The screen appears to have a matte anti-glare coating, which helps eliminate any reflections from sun that might be peeking in to your room.

The monitor has a number of suitable ports for connecting to your PC including a DisplayPort 1.4, two HDMI 2.0 ports, dual-USB 3.0, and a headphone jack. We wish there were newer HDMI 2.1 ports, as anything above 60hz at 4K via the HDMI (PS5/Xbox) is unachievable.

One thing to note, if you want to get the full 144Hz at 4K with 10-bit color depth, you need a decent graphics card that supports DisplayPort 1.4 DSC. If you’re using something older, you’ll be limiting yourself to 95Hz with 10-big color or 120Hz with 8bit color at 4K UHD.


For a newly launched monitor, the LG 27GN950 provides fantastic value for money at the moment. If you compare similar 27” 4K 144Hz IPS models, it’s got a faster response time speed, better HDR picture quality and DSC.


This new monitor from LG is absolutely fantastic. It will most likely become my daily driver. It’s definitely fair to say the LG 27GN950 might be the best 27” 4K 144Hz IPS monitor available at the moment. If you need HDMI 2.1 connectivity, perhaps wait a few months and see what comes out.
