LG UltraGear 27GX704A-B – 240 Hz OLED Gaming Monitor

About the LG UltraGear 27GX704A-B

The UltraGear 27GX704A-B is a 240Hz OLED gaming monitor built for competitive players who want both speed and stunning visuals. At 1440p resolution, it hits the sweet spot between sharp detail and high framerates. The OLED panel delivers perfect blacks and infinite contrast that IPS monitors simply cannot match. Whether you're grinding ranked matches or editing stream highlights, this 240Hz OLED gaming monitor handles it all.

What This LG UltraGear 27GX704A-B Does for You

That 0.03ms response time is among the fastest available, eliminating ghosting in games like Apex Legends and Valorant. No more blur when enemies strafe or when you flick shots. The 240Hz refresh rate keeps motion buttery smooth, giving you split-second advantages in competitive play. Both G-SYNC Compatible and FreeSync Premium Pro support mean no screen tearing, whether you run NVIDIA or AMD. The 98.5% DCI-P3 color coverage with factory calibration makes this a solid choice as the best monitor for gaming and programming.

Display Quality That Stands Out

This 1440p OLED monitor delivers true HDR with VESA DisplayHDR 400 True Black certification. Unlike LCD monitors with edge-lit zones, OLED lights each pixel individually. Dark scenes in games like Resident Evil or Alan Wake 2 look incredible with perfect blacks. The panel switches pixels in 0.03ms, so fast motion stays sharp without trailing. LG includes Black Stabilizer and Dynamic Action Sync features to optimize visibility in dark corners without washing out the image.

Is 240Hz at 1440p better than 4K at 144Hz for competitive gaming?

Yes, the LG Singapore warranty covers panel defects including burn-in. LG also includes pixel protection features like screen shift and logo dimming to prevent burn-in.
