The 30-Second Version
A stunningly fast 300Hz IPS panel with killer color and a tank-like stand. It's the sensible, no-burn-in champion that makes OLEDs look like a risky splurge.
Overview
The LG UltraGear 27G640A-B is the monitor you buy when you're done messing around. It's a 27-inch, 1440p IPS panel that pushes a blistering 300Hz refresh rate, and it nails the fundamentals so well that it's become a top-seller for a reason. The one thing to know is this: it delivers top-tier competitive speed without forcing you to live with the washed-out colors of an older TN panel. You get genuine visual punch right out of the box.
We see this monitor sitting in the 95th percentile for social proof, and honestly, the buzz checks out. It's not trying to be a 4K OLED showpiece. It's a purpose-built tool for gamers who want high frame rates, excellent motion clarity, and a color-accurate IPS screen that's just as good for work as it is for fragging. The stand is a tank, the connectivity is modern, and it just works.
Performance
What surprised us most is how well this IPS panel keeps up with the 300Hz refresh rate. You usually expect some ghosting or blur when you push an IPS this hard, but the 1ms response time here is legit. In our database, its performance sits in the 91st percentile, which is outstanding. Scrolling through web pages and whipping around in Apex Legends feels instantaneous. The G-Sync compatibility is flawless on our test bench, completely eliminating tearing without adding input lag. It's not just fast on paper, it feels fast in your hands.

Value & Pricing
Pricing on this thing is all over the map, with a wild spread from $192 to over $87,000 from third-party scalpers. Ignore the noise. At its normal street price around $400-$500, it's a fantastic deal. You're getting a genuine 300Hz panel with great color and a premium build. If you see it dip toward the lower end of that range from a reputable seller like Newegg, it's a steal. Just don't pay a cent over MSRP.
Price History
vs Competition
The elephant in the room is the new wave of 1440p OLEDs like the ASUS ROG Strix XG27AQDMG and the MSI MAG 271QPX. Those will give you perfect blacks and instant response times, but they cost significantly more and come with burn-in anxiety. The LG's IPS panel is a stress-free workhorse. Against the Samsung Odyssey G7 G70D, the LG trades a curved VA panel's contrast for wider viewing angles and better color consistency. For a pure esports focus, the BenQ MOBIUZ EX271U with its higher refresh rate might tempt you, but the LG is the better all-rounder for daily driving.

Common Questions
Q: Can this monitor run 1440p at 120Hz on a PS5 or Xbox Series X?
Yes, absolutely. The HDMI 2.1 ports support 1440p at 120Hz, so you'll get a super smooth console experience. It won't do 4K 120Hz, but for 1440p gaming, it's perfect.
Q: Is the 300Hz refresh rate worth it over a 144Hz or 240Hz monitor?
If you're a competitive shooter player with a PC that can push 300+ FPS, the jump in motion clarity is noticeable and addictive. For more casual gaming, 240Hz is already great, but the price difference here is often small enough to just go for 300.
Q: Does the USB-C port work for video and charging a laptop?
It does carry a DisplayPort signal, so you can connect a laptop with a single cable. But the 15W power delivery is weak. It'll trickle-charge a phone or keep a tablet alive, but it won't power most laptops. You'll still need your laptop's charger.
Who Should Skip This
If you're a content creator who needs true HDR for video editing or a gamer who plays exclusively in a dark room and craves perfect blacks, this isn't your monitor. The HDR 400 is just a marketing badge, and the IPS glow will annoy you. Go get an OLED like the MSI MAG 271QPX instead and don't look back.
Verdict
Stop overthinking it. If you want a high-refresh 1440p monitor that's fast, colorful, and built to last, the LG UltraGear 27G640A-B is the easy button. It's a no-compromise gaming display that doubles as a solid productivity monitor, and it does it all without the premium price tag of OLED. This is the new standard for a reason.
