This article takes a close look at the LG ゲーミングモニター UltraGear 27GN65R-B 27インチ (LG UltraGear 27GN65R-B, 27-inch). We go beyond the spec sheet and focus on whether it will actually work well in your setup.
Overview
The LG UltraGear 27GN65R-B is a 27-inch Full HD (1920x1080) IPS gaming monitor with a 144Hz refresh rate and a 1ms GTG response time. In short, it is a solid pick if your GPU handles 1080p well and you want a bigger screen than 24 inches at 144Hz.
If you care most about text sharpness, or you want 240Hz or more for competitive play, other models fit better.
It supports both AMD FreeSync Premium and NVIDIA G-SYNC Compatible, which reduce tearing and stutter when paired with a compatible graphics card. It also accepts HDR10 signals.
With 300 cd/m² brightness, though, treat HDR as something it can accept rather than a real highlight.
The appeal here is balance rather than raw speed. You get a stand with pivot, height and tilt adjustment, a three-side frameless design, and a three-year warranty with a zero bright-pixel policy.
Those are often missing at this price. The trade-off is pairing 27 inches with 1080p, which we cover in Before You Buy.
Compatibility Guide
The monitor has two inputs: one HDMI and one DisplayPort. DisplayPort is the recommended connection for 144Hz on a PC.
If you use G-SYNC Compatible on an NVIDIA GPU, connect over DisplayPort. A common mistake with monitors in this class is connecting over HDMI and never noticing that it is still running at 60Hz.
After connecting, check your software settings. In Windows, set the refresh rate to 144Hz under Advanced display settings, then turn on FreeSync or G-SYNC Compatible in your GPU control panel.
Also make sure FreeSync is enabled in the monitor's on-screen menu. If you skip any of these steps, you are using a 144Hz monitor at 60Hz.
1080p is a relatively light resolution for a GPU. Light competitive games can reach 144fps even on lower mid-range cards.
Demanding new AAA titles need a mid-range or better GPU and some tuning to hold 144fps. When fps falls below 144, variable refresh rate (VRR) keeps motion looking smooth.
FreeSync Premium requires low framerate compensation (LFC), which helps when frame rates drop sharply.
Game consoles connect over HDMI. Because there is only one HDMI port, you cannot keep several consoles connected at once without an HDMI switch.
Whether a console can output 120Hz depends on the console and the game, so check the manufacturer's specifications if that matters to you.
With the stand, the monitor measures 614 mm wide, 466 to 576 mm tall and 291 mm deep, and weighs 7.2 kg.
The stand offers 110 mm of height adjustment, -5 to 15 degrees of tilt, and pivot. Plan on a desk at least 60 cm deep to fit the 291 mm stand and still sit a comfortable distance from a 27-inch screen.
On a shallow desk, VESA 100x100 mounting lets you use a monitor arm instead. Check the panel weight without the stand on the product page and compare it with the arm's load rating.
There are no built-in speakers. PC audio needs headphones, external speakers or a USB audio device.
If you connect a console over HDMI, plan how you will get audio out. Check the product page to see whether it has a headphone jack.

The 27GN65R-B launched in 2022. In September 2026 it was ¥34,040 on Amazon Japan.
Prices change with sales and sellers, so check the current price on the product page before you buy. Also as of September 2026, Amazon Japan showed 4.4 out of 5 stars, but from only 17 reviews.
The score is good, but a sample that small says little about unit-to-unit variation or how support handles problems.
The box includes an HDMI cable and a warranty card. LG offers three years of free repair, and the zero bright-pixel policy covers repair if even one stuck bright pixel appears.
LG also lists 27-inch and larger monitors as eligible for on-site repair. Pixel-defect coverage is rare on gaming monitors, so this is a real plus.
Warranty terms and service areas can change, so confirm them with LG before buying.
300 cd/m² brightness and a 1000:1 contrast ratio are typical for IPS. They are fine in a normally lit room, but HDR content will not have much punch.
Response times like 1ms GTG are usually measured with strong overdrive. Pushing overdrive too far can add bright halos around moving objects (overshoot).
Try each response time setting in the on-screen menu and keep the one that looks cleanest to you.
27 Inches at 1080p: What It Means
A 27-inch 1080p panel has about 82 ppi. That is lower than a 24-inch 1080p screen (about 92 ppi) or a 27-inch 1440p screen (about 109 ppi).
At the same viewing distance, text and icons look softer. This is the complaint buyers raise most often after purchase.
In games, the screen is moving and you take in the whole picture, so the softness is less noticeable. Reading long web pages, working in spreadsheets or writing code makes jagged text easier to spot.
Sitting 60 to 70 cm back helps, so think about your desk depth too.
The upside of 1080p is a lighter GPU load. It has about 56% as many pixels as 1440p, so the same GPU delivers higher frame rates.
If you want high fps from your current GPU but find 24 inches too small, this combination makes sense.
Compared with Alternatives
| Model | Screen | Strength | Best for |
|---|---|---|---|
| LG UltraGear 27GN65R-B | 27-inch FHD IPS 144Hz | Flexible stand, zero bright-pixel warranty | 144Hz on a bigger screen without overspending |
| MSI MAG 272F X24 | 27-inch FHD 240Hz | 0.5ms, higher refresh rate | Higher fps at the same size and resolution |
| ASUS ROG Swift PG259QNR | 24.5-inch FHD 360Hz | Built for competitive play | Serious FPS players |
| LG 27UP600K-W | 27-inch 4K | Sharpness over refresh rate | Work and video with crisp text |
Among 27-inch 1080p monitors, the MSI MAG 272F X24 runs at 240Hz and suits players who put refresh rate first. The 27GN65R-B wins on its adjustable stand and warranty.
The ASUS ROG Swift PG259QNR is a 24.5-inch, 360Hz esports monitor, so it is a different kind of product.
The LG 27UP600K-W is also 27 inches but prioritizes sharpness, which makes it better for work than for games. Your choice comes down to speed, sharpness, or everyday usability and support.
The 27GN65R-B is the pick if usability and support come first.
Who It's For
- Gamers whose GPU can run around 144fps at 1080p and who want to move up from 24 to 27 inches
- Casual to mid-level FPS and battle royale players who do not need 240Hz or more
- Anyone who wants pivot and height adjustment without buying a monitor arm
- Buyers who value warranty coverage, including pixel defects
- People who want one screen for both gaming and video
It fits best for gamers with a modest GPU who want a bigger screen. Coming from a 60Hz monitor, 144Hz with 1ms GTG makes motion much easier to follow.
FreeSync Premium also smooths out stutter when frame rates fluctuate.
IPS viewing angles make it comfortable for video and quick photo checks. The frameless design works well in a dual-monitor setup.
With pivot support, you can also stand it vertically as a secondary screen for chat or documents.
Before You Buy
Can you live with softer text? At about 82 ppi, text work shows the limits of 1080p at 27 inches.
If you do a lot of reading or office work, look at a 27-inch 1080p monitor in a store first if you can. If you spend more time working than gaming, a 27-inch 1440p model is the safer choice.
144Hz is not automatic. You need DisplayPort, the right Windows refresh setting and VRR enabled on the GPU.
The included cable is HDMI, so you may need to buy a DisplayPort cable. Check the box contents on the product page and order one with the monitor if needed.
Keep HDR expectations modest. It accepts HDR10 signals, but brightness is 300 cd/m².
If you want real HDR contrast, look at brighter models or OLED. If HDR looks dim or washed out, turning HDR off in Windows can actually look better.
Black levels are typical IPS. At 1000:1 contrast, dark scenes look slightly gray, and in a dark room you may notice IPS glow in the corners.
If you mainly play horror or other dark games, decide whether you can accept that.
Two inputs, no speakers. One PC and one console fill both ports, and you need separate audio.
If you connect many devices, budget for a switch and audio gear.
For serious competition, go 240Hz or higher. 144Hz is smooth, but 240Hz and 360Hz monitors are a different class.
If you are chasing high ranks, buying a faster monitor now avoids replacing this one later.
Check the seller and price. The listing checked in September 2026 was sold and shipped by a third-party retailer (B-Surprise), not LG.
Warranty claims usually require proof of purchase, so keep your invoice or order history. The price in this article comes from Amazon Japan, not an overseas store.
Listing details can differ by seller, so confirm the photos and the model number 27GN65R-B before ordering.
The review count is small. 4.4 out of 5 is a good score, but 17 reviews could be skewed by chance.

FAQ
Q. Does it work with PS5 or Nintendo Switch? A.
Yes, over HDMI. There is only one HDMI port, so you need a switch for multiple consoles.
120Hz support depends on the console and the game.
Q. Does VRR work with NVIDIA GPUs?
A. Yes, it is G-SYNC Compatible. Connect over DisplayPort and enable it in the NVIDIA Control Panel.
Q. Why am I stuck at 60Hz? A.
The usual causes are an HDMI connection, Windows still set to 60Hz, or a cable that does not support the higher rate. Switch to DisplayPort and check your display settings.
Q. Can I use a monitor arm?
A. Yes, it supports VESA 100x100. Match the panel weight without the stand to the arm's load rating.
Q. Is it good for work? A.
It works, but text looks softer at 27 inches and 1080p. If you work long hours, compare 1440p or higher models first.
