LG UltraGear 27GS75Q-B 27" Black
The 27-inch IPS panel delivers a 2560 x 1440 resolution at 180Hz with a 1ms response time, making motion crisp for fast-paced gaming, and it supports both G-Sync and FreeSync. Its 99% sRGB coverage and HDR10 add color accuracy for mixed use, while the ergonomic stand with height, tilt, swivel, and pivot adjustments suits long sessions. Best for gamers who want a high-refresh QHD monitor for competitive play and occasional office work, though its 300-nit brightness is modest for bright rooms.

The proof
Performance
The 180Hz refresh rate is the headline here, and it delivers. Paired with the 1ms response time, motion is buttery smooth, and both G-Sync and FreeSync support means you're covered whether you're team green or team red. What surprised us most is how well the IPS panel handles the jump from 1080p. Owners consistently describe it as night and day, and our data shows the performance sits in the 82nd percentile for this category. That's strong, especially for the price. The 300 nits brightness isn't going to blow you away, but for a desk setup it's plenty.

vs Competition
Stack this against the Samsung Odyssey OLED G6 G60SF or the Alienware AW2725D and you're looking at OLED panels that cost significantly more and deliver better contrast and HDR. But here's the thing: if you're not ready to drop OLED money, the LG gets you 90% of the gaming experience for a fraction of the price. The ASUS ROG Strix XG27UCDMG and MSI MPG 271QR QD-OLED X50 are also in the conversation, but they're chasing 4K and OLED territory. For 1440p IPS at 180Hz, the LG is the value king, and the only real trade-off is HDR performance and peak brightness.

Value & Pricing
At $325, this is a no-brainer. You're getting a 180Hz QHD IPS panel with G-Sync and FreeSync for less than what many 1080p high-refresh monitors cost a year ago. The value score from our database puts it in the 72nd percentile overall, but for pure gaming dollar-per-frame, this thing punches way above its weight. Buy it.

Overview
The LG UltraGear 27GS75Q-B is the monitor you buy when you're done squinting at 1080p and ready to see what your GPU can actually do. At $325, this 27-inch QHD IPS panel hits 180Hz with a 1ms response time, and it's the kind of upgrade that makes you wonder why you waited so long. The one thing to know: this is the best value 1440p gaming monitor we've seen in a while, and the 4.7-star rating across 382 reviews backs that up.
Common Questions
Q: Can I adjust the height of this monitor?
The spec sheet lists height adjust, tilt, swivel, and pivot, but some owners mention the stand feels basic. If you need serious ergonomic flexibility, grab a VESA mount since it's 100x100 compatible.
Q: What's the color gamut coverage?
LG lists 99% sRGB coverage, which is solid for gaming and everyday use. It's not a wide-gamut panel for pro photo work, but colors look vibrant and accurate out of the box.
Q: Does this monitor actually do HDR?
It supports HDR10, but with 300 nits peak brightness, don't expect OLED-level HDR. It's more of a compatibility checkbox than a feature you'll notice in games.
Who Should Skip This
If you're chasing true HDR performance or deep blacks, this isn't it. The 300 nits brightness and IPS panel can't compete with OLED options like the Samsung Odyssey OLED G6 or Alienware AW2725D. Go grab one of those instead if HDR matters more than saving money.
Verdict
The LG UltraGear 27GS75Q-B is the monitor we'd recommend to anyone still on 1080p who wants a massive upgrade without selling a kidney. The 180Hz refresh rate, QHD resolution, and dual sync support make it a fantastic gaming display, and the 4.7-star owner rating confirms it's not just spec-sheet hype. The brightness adjustment quirk is annoying but hardly a dealbreaker. If you're in the market for a 1440p gaming monitor under $350, stop scrolling and buy this one.
