LG 27GL83A-B 27 inch Ultragear QHD IPS 1ms Nvidia G-sync compatible gaming monitor black review


Does it support faster gaming? A ultra-fast speed of 144Hz allows immediate action on the screen. Objects are rendered more clearly for smoother gameplay and an almost surreal visual fluidity. The LG 27GL83A display is based on an IPS panel with wide 178-degree viewing angles, 10-bit color depth support, 1ms (GtG) response time, 1440p resolution, and a 350-nit peak brightness, while its static contrast ratio varies between 700:1 and 1,000:1, depending on the unit.

LG 27GL83A-B 27 inch Ultragear QHD IPS 1ms Nvidia G-sync compatible gaming monitor black review


The stand is sturdy and offers decent ergonomics, including up to 110mm height adjustment, 90° pivot, -5°/15° tilt, and 100x100mm VESA mount compatibility. You cannot swivel the stand to the left/right, though.

There’s no RGB lighting of any kind, while the monitor has a low-haze anti-glare matte coating, which effectively eliminates reflections, but doesn’t make the picture appear grainy.


 It measures 24.2 x 22.6 x 10.8 inches with the stand. Even with the modern design, the display is quite thick, at 2.3 inches at its widest point. The screen offers tilt, height and pivot adjustment, so you can adjust the vertical angle both upward and downward.

It’s mainly black with a red circle on the back, and the stand has wide-set feet. It’s designed as a gaming monitor but fits nicely into any office environment. The bottom bezel is slightly thicker, just like on the LG 27GL850. It’s mostly made of plastic but there are no gaps or loose ends.

Viewing angle

The LG 27GL83A-B has excellent horizontal viewing angles, which is expected from an IPS panel. You won’t lose image accuracy when viewing from the side, which is great if you need to share your screen with a coworker or for co-op gaming.


1440p resolution ensures crisp details and plenty of screen real estate on 27″ sized monitors thanks to the ideal pixel-per-inch ratio of ~108 PPI, which eliminates the need for any scaling.

Color gamut

The LG 27GL83A-B has a good HDR color gamut. It has great coverage of the DCI P3 color space used in most current HDR content. The coverage of the wider Rec. 2020 color space is only decent, so it’s not as future-proof.

Refresh rate

The LG 27GL83A-B has an amazing response time at 60Hz, which is great for console gaming. Unlike at its max refresh rate, the recommended Response Time setting is ‘Normal’, so you might have to change your setting while gaming. This setting has less overshoot and motion blur than the ‘Fast’ setting, but both perform very similarly.


The LG 27GL83A-B has a fast 144Hz refresh rate. It supports AMD’s FreeSync variable refresh rate, and it’s certified by NVIDIA as G-SYNC compatible, but G-SYNC only works over DisplayPort. You shouldn’t have any issues using it with a recent NVIDIA graphics card.

Over HDMI, the 27GL83A-B only supports FreeSync up to 100Hz, but with VRR disabled 144Hz @ 1440p is supported over HDMI.

LG 27GL83A-B 27 inch Ultragear QHD IPS 1ms Nvidia G-sync compatible gaming monitor black Performance review

Playing Resident Evil 2 Remake is exciting, as the monitor makes zombies – the slow, shambling, groaning type – incredible again. You are easily immersed in the shuffling lumps of bloody meat battering down, and the tumble through broken windows and lunge from the shadows is brought to life than before. And, in a game that’s certainly opposite in terms of tone and color palate, Scavenger looks amazing, with all its blue them and fluid movement. Simply put, no matter what game you throw at this monitor, it looks amazing.

In some games like Metro Exodus, you’ll be getting around 50 fps, but thanks to G-Sync, everything feels like you’re playing at the native framerate. G-Sync, for as long as you have a compatible Nvidia graphics card, is basically like cheating and that’s how we all love it.

Great for HDR Gaming

Started off using it with a usb c to hdmi cable coming from my laptop definitely do not recommend that. Switched to hdmi and order a Display Port cable. HDMI worked great but in hdr the image was to dark and a very noticeable yellow tint to the whole screen. Finally got the DisplayPort cable and everything worked way better. HDR was better, imagine was a lot better. Still have a yellow tint but not as noticeable. Definitely need a display port cable for its full potential especially if your buying it for g sync. It has a couple picture modes my go to was vivid. You can adjust black levels and response time or just cycle through game modes. Definitely happy with this monitor HDR to me is a lot better then other monitors. Almost TV quality. The only thing I don’t like is the anti glare layer having that yellow tint but once the game is playing I hardly notice it. I played in both light and dark settings and had no issues

Dell’s 4K monitor is stunning inside and out. We love it’s woven arctic white design that lends to its unique elegant look, allowing it to stand out against the sea of black and gray monitors out there. Its display is impeccable as well. On top of that 4K resolution is a contrast ratio of 3,000:1, support for 1.07 billion colors, up to 4ms response time, and a 178/178 viewing angle that altogether produce stunning, crisp and vibrant visuals that are just as excellent for gaming as they are for media consumption and productivity. It isn’t the cheapest 4K option out there, but the price of entry isn’t bad either. And, considering what you’re getting, you’ll be glad to spend just a little more.
