Who it fits
Good fit for
This monitor suits competitive gamers who prioritize frame rate and responsiveness. The 300Hz refresh rate and 1ms GtG response time help you react faster in fast-paced titles. The QHD resolution on a 27-inch screen offers a good balance of clarity and performance. If you use both NVIDIA and AMD GPUs, the G-SYNC compatibility and FreeSync Premium support ensure smooth visuals. The USB-C port and adjustable stand also make it a practical choice for multi-device setups.
Who should skip it
You should look elsewhere if you need high-end HDR performance. This monitor has VESA DisplayHDR 400 certification, which is entry-level and may not deliver the deep contrast or bright highlights you expect from premium HDR displays. If you require true cinematic blacks or intense brightness for media consumption, this IPS panel may not meet your standards. Additionally, if you prefer a 4K resolution for text clarity or detailed work, the QHD panel might feel less sharp than higher-resolution alternatives.
Verdict: The LG 27G640A-B is a solid choice for gamers seeking high refresh rates and reliable sync technology. It delivers the speed and clarity needed for competitive play without unnecessary frills.
Key specs explained for you
Panel Type: IPS
IPS panels offer wide viewing angles and consistent color accuracy from almost any position. You get vibrant visuals even if you sit off-center. This makes it ideal for shared spaces or multi-monitor setups. Unlike VA panels, IPS avoids dark smearing in dark scenes, ensuring clearer images during fast-paced gaming sessions.
Resolution: 2560 x 1440
QHD resolution provides sharp, detailed images on a 27-inch screen. You see more workspace and clearer text than 1080p, without the heavy GPU load of 4K. This balance suits competitive gamers who need clarity without sacrificing frame rates. It is the sweet spot for most modern gaming PCs.
Refresh Rate: 300Hz
A 300Hz refresh rate updates the image 300 times per second. You experience smoother motion and reduced input lag in fast shooters. This high speed benefits competitive players who react to split-second changes. Compare this to 144Hz or 240Hz models, which feel slightly less fluid in intense action sequences.
Response Time: 1ms GtG
1ms Gray-to-Gray response time minimizes ghosting and trailing behind moving objects. You see crisp edges during rapid camera turns. This speed complements the high refresh rate for fluid gameplay. It ensures that fast-moving visuals remain distinct, which is critical for tracking enemies in competitive multiplayer titles.
Sync Technology: G-SYNC Compatible, FreeSync Premium
These technologies synchronize the monitor's refresh rate with your GPU's frame output. You eliminate screen tearing and stuttering for a seamless experience. G-SYNC Compatible works with NVIDIA cards, while FreeSync Premium supports AMD GPUs. This versatility ensures smooth visuals regardless of your graphics card brand, enhancing overall immersion.

According to the listing, the LG 27G640A-B features a slim-profile display with narrow bezels. The monitor is finished in black, matching typical gaming setups. You get a 27-inch screen that balances desktop footprint with visual immersion. The dimensions are 24.2 inches wide, 21.2 inches high, and 9.4 inches deep. It weighs 12.1 pounds. This weight suggests a sturdy base, though the listing does not specify the exact stand material. You can place it on standard desks without worrying about excessive bulk.

Ergonomics are a key part of the build. The listing highlights adjustable height, tilt, swivel, and pivot controls. These adjustments let you customize your view for long sessions. You can raise the screen to eye level or tilt it to reduce glare. The pivot function supports vertical orientation, which is useful for coding or document review. This flexibility means you can adapt the monitor to your posture, not the other way around.

The slim profile and narrow bezels help it fit neatly into multi-monitor arrangements.

It provides 15W of power delivery. You can connect devices and charge them simultaneously. This reduces cable clutter on your desk.
In daily use, the 300Hz refresh rate and 1ms GtG response time are key. These specs minimize motion blur and ghosting. You experience fluid motion during fast-paced scenes. The IPS panel ensures consistent colors from wide angles. This is useful if you share your space or adjust your seating position.

Before You Buy This Monitor
Before you buy this LG 27G640A-B, verify your PC can actually drive 300Hz at QHD resolution. The dual HDMI 2.1 ports help, but DisplayPort 1.4 is often required for maximum refresh rates on NVIDIA cards. You should also ensure your graphics card supports G-SYNC Compatible or FreeSync Premium to prevent screen tearing. Since the monitor lacks built-in speakers, plan for a headset or external audio setup. The USB-C port provides only 15W of power delivery, so it will not charge high-power laptops quickly. Keep the IPS panel clean with a microfiber cloth; avoid harsh chemicals that might damage the coating. This model fits best in a fast-paced competitive setup. It differs from wider ultrawide options by offering a more standard aspect ratio, which many shooters prefer. Check your desk space, as the adjustable stand requires room for height and pivot adjustments. Ensure your current cables match the required ports to avoid unnecessary purchases.
Check before you buy
- Verify your GPU supports 300Hz at 1440p via DisplayPort.
- Confirm your graphics card is G-SYNC Compatible or FreeSync Premium.
- Check if your desk has space for the adjustable stand.
- Ensure you have external audio since speakers are absent.
