LG UltraGear 27GX790A-B 26.5"

The LG 27GX790A-B is the fastest OLED gaming monitor we've tested, pairing a 480Hz refresh with 0.03ms response and stunning contrast. SDR brightness is lower than some LCDs, there are no built-in speakers, and the stand is huge, but in motion it's untouchable. Look for prices around $700 to $900 for the best value, and make sure your GPU can push those frames. Serious esports players should buy it yesterday; everyone else should weigh speed against versatility.

Here's the thing about the LG UltraGear 27GX790A-B: it's the fastest OLED gaming monitor we've ever tested, and if you're a competitive FPS player with a high-end GPU, it'll feel like cheating. LG stuffed a 26.5" 1440p OLED panel with a 480Hz refresh rate and an advertised 0.03ms response time into a clean, sturdy frame, then backed it with G-Sync and FreeSync Premium Pro. It's aimed squarely at people who obsess over frame times and want every possible edge without sacrificing the inky blacks and vibrant colors OLED brings to the table. Think Valorant, Overwatch, CS2, or any title where reaction time matters more than cinematic vistas.

Our database puts the 27GX790A-B's motion clarity and input latency at the absolute top of the charts, literally a 100th percentile gaming performer. That said, the display's 75th percentile ranking reminds us that not everything is about raw speed: the 2560x1440 resolution and 16:9 aspect ratio are solid but not revolutionary, and while HDR peaks at 1300 nits, SDR brightness is a modest 275 nits, which puts it behind many LCD rivals in a bright room. Still, for the target audience, those trade-offs fade the moment you see how fluid a 480Hz OLED looks in motion.

We've seen prices bounce between $694 and $1,380 across retailers, so shopping around matters. The user reviews are overwhelmingly positive, with an overall sentiment score of 92/100, and owners consistently praise the stunning picture quality and responsive feel. There are gripes, too: no built-in speakers, a large base that dominates a desk, and the perennial OLED burn-in anxiety. But if you've got the GPU muscle to push 480 frames per second, this monitor is ready to show you what modern esports hardware can really do.

We threw every fast-paced test pattern and real game scenario at the 27GX790A-B, and the numbers tell the story. The 480Hz refresh rate combined with the 0.03ms GtG pixel response effectively erases motion blur; there's no smearing, no ghosting, just pixel-perfect tracking even in high-contrast scenes. In our lag tests, input delay was virtually non-existent, which translates to shots landing more reliably in twitch shooters and every mouse movement feeling telepathically connected. This is the best gaming monitor you can buy if speed is your only metric.

OLED contrast does a lot of heavy lifting here, too. The per-pixel lighting delivers true blacks that make dark corridors in horror games terrifyingly deep and HDR highlights pop at up to 1300 nits. Color coverage hits 98.5% DCI-P3, which means games look rich and saturated without veering into unnatural territory. A note of caution: that SDR full-screen brightness ceiling is real. If you like to game with curtains wide open, the 275-nit typical output may wash out a bit compared to a good IPS panel. But for controlled lighting, the visual experience is breathtaking.

The value story is all about timing. At $694 from the right vendor, this is an absurdly good deal, undercutting many 360Hz LCDs while delivering superior contrast and speed. At $1,380, you're creeping into 4K OLED territory and paying a heavy early adopter tax. Currently, the sweet spot is finding it around the $800-$900 mark, which puts it roughly in line with MSI's 321CURX 4K QD-OLED at 240Hz or Alienware's ultrawide 34" QD-OLED, but those trade speed for resolution or size.

If you just want an OLED for casual gaming and content, the older 240Hz LG 27GR95QE or even the 360Hz options offer most of the beauty for a lot less cash. This monitor is a specialty purchase; it only clicks if you can use those 480Hz. If your GPU can't consistently push frame rates above 240fps at 1440p, you're leaving performance on the table, and that makes the premium harder to justify.

The most direct rival is the ASUS ROG Swift PG27AQDP, which uses the same LG Display WOLED panel with a 480Hz refresh rate and similar feature set. In our experience, they're nearly identical in motion performance and picture, so your decision often boils down to price, stand design, and which OSD you prefer. Both are phenomenal, but LG's software has been a bit more polished in recent firmware updates.

If you're willing to sacrifice some speed for higher resolution, the MSI MPG 321CURX offers a 32" 4K 240Hz QD-OLED panel with even wider color coverage and a sharper desktop experience, though at the cost of input lag and frame rates. The Samsung Odyssey Neo G9 is a completely different beast: a 49" super-ultrawide Mini-LED that's amazing for immersion and multitasking but can't touch the 27GX790A-B's motion clarity. For competitive gamers, all roads still lead back to this LG, unless you absolutely need 4K for mixed use.

Console gamers on PS5 or Xbox Series X won't see much benefit from a 480Hz monitor since those systems top out at 120Hz. You'd be using only a fraction of what this screen can do while paying a huge premium, so a 120Hz OLED TV or a 144Hz gaming monitor is a far better match. Similarly, if you do a lot of productivity work like coding or document editing, the low SDR brightness and typical 1440p text clarity might feel like a downgrade next to a good 4K IPS panel.

Mainstream gamers with mid-range GPUs should also look elsewhere unless you plan to upgrade. Pushing 480fps in demanding titles is unrealistic on anything below an RTX 4080 or RX 7900 XTX, and even esports games need a stout CPU. For those users, the LG 27GR95QE 240Hz OLED or an MSI 27" QD-OLED 360Hz will deliver 90% of the visual wow factor for hundreds less.

For the dedicated competitive shooter crowd running high-end GPUs, this LG is the new benchmark. The 480Hz OLED panel delivers motion clarity that has to be seen to be believed, and the support for both G-Sync and FreeSync means everyone gets a tear-free experience. If you're chasing every millisecond of advantage and have the budget, there's nothing better right now.

Casual gamers, content creators, and mixed-use buyers should think carefully. The SDR brightness isn't ideal for productivity in sunlit rooms, the text clarity at 1440p is merely okay, and the lack of speakers means you'll need a headset or desk speakers anyway. In those scenarios, a 4K OLED like the MSI 321CURX or even a quality 240Hz OLED ultrawide will feel more versatile. But if your world is Overwatch 2 and Apex Legends and you want the absolute edge, this monitor is a no-brainer.
