LG UltraGear 27" 26.5"

The LG UltraGear 27GX790A-B is the fastest OLED gaming monitor we've ever tested, with a best-in-class 480Hz refresh rate and 0.03ms response time that competitive gamers will love. The OLED picture quality is stunning, with perfect blacks, though SDR brightness is a bit low. You'll need a beastly GPU to push 480fps, and the price swings from $694 to $1,380, so shop around. If you live for esports and have the hardware, this is an easy recommendation.

LG's UltraGear 27GX790A-B is basically a flex. It's a 27-inch OLED gaming monitor that pushes a frankly ridiculous 480Hz refresh rate at 1440p, and it lands in the 100th percentile for performance in our database. That's not just top-tier, that's the absolute best right now. This thing is built for competitive players who want every possible frame advantage without sacrificing the gorgeous contrast and color you only get from OLED. If you're the type who plays fast-paced shooters, battle royales, or anything where motion clarity is king, this monitor was made for you.

But let's be real, this isn't a casual pickup. The price swings wildly between vendors, from $694 to $1,380, so you'll need to shop smart. And pushing 480 frames per second in modern games demands a seriously powerful GPU, we're talking RTX 4090 territory. The monitor itself is a stunner though, with a slim bezel, a sturdy ergonomic stand that does height, tilt, swivel, and pivot, and some RGB lighting on the back if you're into that. It's heavy at over 9kg, but that weight translates to a solid, premium feel on your desk.

There's a clear trade-off here compared to bright LCD panels. The SDR brightness is a modest 275 nits, which is a weak spot for OLEDs in general and something multiple owners mention. But you're getting true per-pixel blacks, a 1.5M:1 contrast ratio, and 98.5% DCI-P3 color coverage that makes games look incredible. It also packs DisplayPort 2.1 for future-proofing, two HDMI 2.1 ports, and a USB hub. It's a no-compromise speed machine that asks you to compromise a little on brightness and a lot on your wallet.

The headline spec here is 480Hz, and it's not just a marketing number. In our testing, this panel's motion clarity is the best we've ever recorded, landing it at the very top of the charts. The 0.03ms response time means there's virtually no ghosting or blur, even in the fastest twitch shooters. When you combine that with effective G-SYNC and FreeSync Premium Pro support, you get a tear-free, buttery smooth image that feels almost telepathic. It's a genuine competitive advantage if your reflexes are up to the task.

Here's the catch: you need the hardware to feed the beast. Hitting a stable 480fps at 1440p in demanding titles like Warzone or Apex Legends requires a top-of-the-line GPU, and even then you'll likely be dialing down some settings. For less demanding esports titles like Valorant or CS2, it's more achievable. The HDR performance, rated at True Black 400, looks fantastic in dark scenes thanks to the OLED panel's infinite contrast, but the peak brightness won't blow you away in a sunlit room. This is a monitor that performs best in a controlled lighting environment where those deep blacks can truly shine.

Pricing on this monitor is all over the place. We're seeing a spread of $686 across different vendors, with some listing it around $694 and others asking nearly $1,400. At the lower end of that range, this monitor is a screaming deal for the sheer speed and OLED quality you're getting. It undercuts many competitors with similar specs. At the high end, it's a much tougher sell, and you'd be wise to wait for a sale or price match.

Compared to the broader market, you're paying a premium for that 480Hz refresh rate. If you don't absolutely need the highest possible frame rate, you can save a significant chunk of change by dropping down to a 240Hz or 360Hz OLED. But if you're a competitive gamer who views every frame as an investment, the value proposition is clear. Just make sure you're checking multiple storefronts before you click buy, because the savings can be substantial.

The ASUS ROG Strix XG27AQDMG is the most direct rival, offering a similar 27-inch 1440p OLED experience but at a lower 240Hz refresh rate. The ASUS gets brighter in SDR, which makes it a better fit for mixed-use setups in brighter rooms. But it can't touch the LG's motion clarity. If you're purely a competitive gamer, the LG wins. If you split your time between gaming and media consumption in a well-lit space, the ASUS might be the smarter, often cheaper choice.

Then there's the Alienware AW3423DWF, a 34-inch ultrawide QD-OLED. It's a completely different beast, prioritizing immersion and color volume over raw speed. The Alienware is better for cinematic single-player games and productivity, but its 165Hz refresh rate feels sluggish next to the LG. For esports, the LG is in a different league. The MSI MPG 321CURX is another 32-inch 4K 240Hz option that splits the difference, offering higher resolution for detail but sacrificing the extreme motion clarity of the 480Hz panel. It really comes down to what you value more: pixel density or speed.

You should skip this monitor if you're not a hardcore competitive gamer. If your gaming diet consists of sprawling RPGs, strategy games, or immersive single-player adventures, a 480Hz refresh rate is wasted horsepower. You'd be much better served by a larger, higher-resolution display like the Dell UltraSharp U4025QW for productivity, or a brighter QD-OLED ultrawide like the Alienware AW3423DWF for immersion. The lower SDR brightness also makes this a poor choice if your setup is in a very bright room with lots of windows and you can't control the lighting.

Also, if you're on a tighter budget or don't own a flagship GPU, this monitor doesn't make sense. The cost of entry is high, and you won't see the full benefit without a system that can push extreme frame rates. A 240Hz OLED or a high-quality IPS panel will give you a fantastic experience for hundreds of dollars less, and you can put the savings toward a GPU upgrade that will actually make a bigger difference in your overall gaming experience.

If you're a competitive gamer who mainly plays fast-paced shooters and has a high-end GPU to push the frames, this is the monitor to beat. The combination of OLED contrast and 480Hz clarity is transformative, and there's simply nothing faster on the market right now. The low input lag and flawless VRR support make it feel like a direct extension of your mouse hand. Just be prepared to game in a room without harsh glare, and factor in the cost of a good pair of headphones since there are no built-in speakers.

For everyone else, this monitor is probably overkill. If you play a mix of single-player RPGs, strategy games, and some casual shooters, a 240Hz OLED or a brighter mini-LED panel will serve you better for less money. The LG's strengths are hyper-focused on competitive advantage. If you're not actively trying to climb the ranked ladder, you're paying a premium for speed you won't fully utilize. In that case, save the cash and put it toward a better GPU or a nice set of desktop speakers.
