Key takeaways
- 240Hz plus OLED response gives outstanding, smear-free motion clarity
- Perfect OLED blacks and strong HDR contrast
- QHD at 27 inches is sharp yet easy for mid-range GPUs to drive fast
- WOLED panel handles reflections and text better than glossy rivals
What's inside
The LG UltraGear 27GX704A-B is a 27-inch QHD OLED gaming monitor running at 240Hz with a rated 0.03ms response time, G-Sync compatibility, and DisplayHDR True Black 400. It is LG’s play for the competitive-leaning sweet spot: 1440p resolution that a mid-range card can drive at high frame rates, paired with the motion clarity and contrast of an OLED panel.
It is aimed at players who prioritize speed and responsiveness but refuse to give up OLED image quality, and who find 4K OLED panels too demanding or too expensive. If you want a fast, punchy 27-inch display for a mix of competitive shooters and immersive single-player games in 2026, this monitor targets exactly that balance.

Design & Build
LG keeps the UltraGear styling clean and functional: slim bezels, a stable stand with tilt and height adjustment, and a restrained aesthetic with a touch of rear accent lighting. The panel uses LG’s WOLED technology, which favors sharper text rendering and stronger reflection handling than glossy QD-OLED rivals. Connectivity includes HDMI 2.1 and DisplayPort, and LG bundles its usual burn-in mitigation tools and a warranty that covers the panel. The build feels solid without straying into over-designed gamer excess.
Performance
At 240Hz with OLED’s effectively instant pixel response, motion is exceptionally clean, with none of the smearing that dogs LCD panels in fast scenes. This is where the monitor shines for competitive play: fast flicks and tracking feel crisp and connected. The QHD resolution on a 27-inch panel gives a sharp, dense image that is far easier to drive at high frame rates than 4K, so mid-range GPUs can actually hit that refresh ceiling.
Contrast is superb thanks to OLED’s per-pixel blacks, and HDR content looks rich, though like all current OLEDs full-screen brightness is modest compared with high-end LCDs. The WOLED panel’s text clarity is a practical plus if you also work at the desk. The main compromise is that 1440p is not as razor-sharp as 4K, which some buyers with powerful cards may miss.
Pros & Cons
- 240Hz plus OLED response gives outstanding, smear-free motion clarity
- Perfect OLED blacks and strong HDR contrast
- QHD at 27 inches is sharp yet easy for mid-range GPUs to drive fast
- WOLED panel handles reflections and text better than glossy rivals
- Full-screen brightness is modest next to premium LCDs
- 1440p is less crisp than 4K for those with high-end cards
- OLED burn-in remains a consideration for heavy static-content use
Alternatives to Consider
If you crave even faster motion, the LG UltraGear 27GX790A-B pushes the same 27-inch QHD panel to a blistering 480Hz for hardcore esports players. Buyers who want 4K sharpness and a dual-mode refresh trick should look at the LG 32GX850A-B, a 32-inch 4K OLED that switches between high resolution and high refresh. For a wraparound experience, the ultrawide LG 45GX950A-B curved 5K2K OLED offers a dramatically wider canvas at a much higher price.
Frequently Asked Questions
Is 1440p at 27 inches sharp enough?
Yes, for most gamers it strikes an excellent balance. The pixel density on a 27-inch QHD panel produces a crisp image, and the lower resolution than 4K means your graphics card can far more easily sustain the 240Hz refresh rate.
Do I need a top-tier GPU for this monitor?
No. Because it is 1440p rather than 4K, a capable mid-range card can drive high frame rates and take advantage of the 240Hz panel. This is a big part of the monitor’s appeal versus more demanding 4K OLEDs.
How does WOLED compare to QD-OLED?
LG’s WOLED panels generally offer better reflection handling and clearer text, while QD-OLED tends to have more saturated, brighter color. Both deliver perfect blacks; the choice comes down to whether you prioritize color pop or desktop clarity and glare control.
Is it good for competitive gaming?
Very much so. The combination of 240Hz, near-instant OLED response, and low input lag makes fast-paced shooters feel sharp and responsive, which is exactly the audience this panel targets.
Verdict
The LG UltraGear 27GX704A-B is one of the smartest OLED gaming buys in 2026, delivering elite motion clarity and gorgeous contrast at a resolution mid-range systems can actually push to 240Hz. You give up some outright sharpness versus 4K and the usual OLED brightness ceiling, but for fast, immersive gaming without a flagship GPU, it hits a near-ideal balance.
