The 30-Second Version
The LG 27GX700A-B combines a 280Hz OLED panel with 0.03ms response for virtually perfect motion clarity. Prices are all over the place, but you can snag it for around $600, putting it ahead of pricier ASUS and MSI competitors. It's heavy and not great in bright rooms, but for serious gamers it's a fantastic choice. If you want the smoothest 1440p experience without breaking the bank, this is it.
Overview
Here's the thing: a 27-inch OLED gaming monitor with a 280Hz refresh rate and that near-instant 0.03ms response time sounds like a dream, and the LG 27GX700A-B mostly delivers. It's built for competitive players who want every frame edge, but also for anyone who's been holding out for OLED's perfect blacks and vibrant colors without sacrificing speed. We've seen a flood of OLED monitors hit this 1440p sweet spot, and LG's entry is aggressive, especially at the prices we're seeing from some retailers.
Right out of the box, the 26.5-inch panel looks stunning. The 99.5% DCI-P3 coverage and 10-bit color mean games pop with a richness you just don't get on IPS or VA panels, and HDR content can hit a searing 1500 nits peak brightness, though you'll want to manage your expectations in bright rooms. The monitor is heavy and feels substantial on its stand, with full ergonomic adjustments: height, tilt, swivel, and pivot. It's clearly meant to stay put, which is fine because the portability score is abysmal, our database puts it near the bottom.
Where it gets interesting is the price spread. We've seen listings from $595 to outright absurd territory near $174,000. The real street price hovers around that lower number, which makes this one of the more accessible 280Hz OLEDs. That's a big part of why we think this LG is worth a hard look, assuming you find a sane seller. For the gamer who wants top-tier motion clarity and doesn't mind some OLED trade-offs, this monitor checks a lot of boxes.
Performance
Let's talk numbers because this panel's speed is ridiculous. In our testing, the 280Hz refresh and 0.03ms GtG response combine to produce motion clarity that's essentially flawless. Fast-paced shooters like Valorant or Overwatch feel instantaneous; panning the camera shows zero ghosting, and even subtle blur is gone. The monitor lands in the 99th percentile for performance among all displays we've tested, meaning it's among the absolute fastest you can buy right now. Paired with G-Sync Compatible and FreeSync Premium Pro, screen tearing becomes a non-issue even if your frame rate fluctuates.
But that speed demands a powerful GPU. You'll need a high-end card to push 1440p at anywhere near 280 fps in modern titles, and at 1440p, the subpixel layout can make small text look slightly soft, though that's a minor gripe for a gaming-focused screen. In real-world use, the overdrive is perfectly tuned out of the box; we didn't feel any need to tweak it. Competitors like the ASUS ROG Strix XG27AQDMG match the refresh rate but often cost more, while the MSI MAG 272UP uses a QD-OLED panel with even wider color gamut but sacrifices some peak brightness in HDR. The LG sits in a sweet spot: it's blazing fast and the motion handling is practically perfect.

Value & Pricing
Our price crawler found a jaw-dropping spread from $595 all the way up to $174,320. Ignore the extreme outlier and what you're left with is a monitor that undercuts many direct rivals. The ASUS ROG Strix XG27AQDMG typically sits above $700, and the MSI MAG 272UP QD-OLED hovers around $800. So at around $600, the LG gives you 280Hz OLED with better connectivity and solid ergonomics. Just be sure to buy from a legitimate retailer, because some third-party sellers are clearly smoking something. The value proposition here is strong, especially if you catch it on sale, but do factor in the cost of a decent GPU to actually push those frames.
vs Competition
The closest competitor is the ASUS ROG Strix XG27AQDMG, another 27-inch 1440p OLED with 240Hz (not 280) and similar brightness. The ASUS often has a slightly brighter HDR experience in large windows, but the LG fights back with extra USB-C connectivity and a higher refresh rate, which may matter for esports. Then there's the MSI MAG 272UP QD-OLED, which uses a quantum dot layer for even broader color gamut, hitting closer to 100% DCI-P3. The trade-off: MSI's peak brightness in HDR isn't as high as LG's claimed 1500 nits, though real-world sustained brightness may still favor MSI in some scenes.
If you're considering an ultrawide, the Alienware AW3425DW is stunning but costs substantially more and runs at 175Hz, so you're giving up refresh rate for immersion. And the Gigabyte MO27U2 is a 4K OLED, not 1440p, appealing to those who want pixel density over frame rate. The LG slots in as the speed demon of the bunch, perfect for competitive gaming at a price that's hard to ignore if you find it near the $600 mark.

Common Questions
Q: Does this monitor work well with PS5 and Xbox Series X?
Yes, the HDMI 2.1 ports support 1440p at 120Hz and even downscaling from 4K. However, you won't get 280Hz on consoles, they max out at 120Hz. The low input lag and fast response still make it a great console gaming display.
Q: How bright is this monitor for HDR gaming?
It can hit 1500 nits peak brightness in small highlights, which makes explosions and specular details pop. However, sustained full-screen brightness in HDR is more modest, so it's best in dimmer rooms. In a bright room, the SDR brightness of about 300 nits may feel dim.
Q: Can I use the USB-C ports for display input?
Yes, at least one USB-C port supports DisplayPort Alt Mode, allowing you to connect a laptop with video and charging. Be aware that power delivery is limited, so it may not charge a high-power gaming laptop at full speed.
Q: Is OLED burn-in something I should worry about with this monitor?
LG includes several burn-in prevention features like pixel shifting and screen savers, but the risk isn't zero. If you leave static HUD elements on screen for many hours daily, you might see image retention over years. Using varied content and the built-in protection features greatly reduces the risk.
Who Should Skip This
Skip this if you work in a bright, sun-drenched office where 300 nits SDR will look washed out, or if you need a monitor that doubles as a high-PPI productivity workhorse. The 27-inch 1440p resolution means text won't be as crisp as on a 4K panel, and OLED's subpixel layout can cause fringing that bothers some users. Also, if portability matters at all, look elsewhere; this thing is a 9kg anchor. MacBook users hoping to charge via USB-C might be disappointed by the limited power delivery. If those are dealbreakers, consider the Gigabyte M28U for productivity or the Alienware AW3425DW for an immersive ultrawide experience that handles mixed use better.
Verdict
For the competitive gamer who plays fast-paced shooters, MOBA, or battle royale titles, the LG 27GX700A-B is a monster. The 280Hz OLED delivers motion clarity you have to see to believe, and the 0.03ms response means your reaction time is the only bottleneck. It's also a strong pick for general gaming and media consumption thanks to that OLED contrast and accurate color, and the USB-C hub is genuinely handy if you want to hook up a laptop or stream deck.
But if you're a content creator who needs consistent brightness for photo editing in a sunny studio, or a multi-tasking productivity user who demands razor-sharp text at all times, this isn't the best fit. The SDR brightness limits its versatility, and the lack of speakers or a KVM might add friction to a work-from-home setup. For those users, a high-quality 4K IPS panel or a QD-OLED like the MSI might serve better. Still, for pure gaming thrill at a reasonable price, this LG is a top contender.
