Overview

The LG 27GR83Q-B is a 27-inch IPS gaming monitor running at 2560x1440 (QHD) with a 240Hz refresh rate and 1ms gray-to-gray response time. Those three specs together define its value proposition: QHD provides 78% more pixels than 1080p for noticeably sharper text and textures at a screen size where the density difference is clearly visible, while 240Hz nearly doubles the frame throughput of the 144Hz panels that dominated this segment until recently. The IPS panel covers 95% of DCI-P3 with VESA DisplayHDR 400 certification, delivering color reproduction that's meaningfully above sRGB-only gaming monitors. Both HDMI 2.1 and DisplayPort 1.4 support the full 240Hz at native resolution, and the panel carries both NVIDIA G-SYNC Compatible validation and AMD FreeSync Premium certification — a practical advantage for users who switch between GPU brands or run mixed systems.

In real-world use, this monitor targets competitive and enthusiast gamers running modern GPUs capable of pushing QHD past 200fps — think RTX 4070 Ti, RTX 4080, or RX 7900 XT class hardware. Below that tier, you'll still benefit from adaptive sync smoothing at lower frame rates, but you're paying for headroom you can't use. LG's gaming-specific features include Dynamic Action Sync for reduced input lag, Black Stabilizer for dark-scene visibility, an on-screen FPS counter, and crosshair overlay — standard competitive tools that work as expected. The DTS Headphone:X integration through the 4-pole headphone jack adds spatial audio processing, though serious competitive players will likely bypass this for dedicated audio. For the segment, this panel hits the intersection of speed, color accuracy, and adaptive sync compatibility that makes it a compelling all-rounder for high-refresh QHD gaming.

Pros & Cons

👍 Pros

  • 240Hz refresh rate at 2560x1440 QHD resolution delivers high frame rates without sacrificing pixel density
  • 1ms GtG IPS panel provides fast pixel response while maintaining the wide viewing angles and color accuracy IPS is known for
  • Dual adaptive sync support (G-SYNC Compatible and FreeSync Premium) ensures tear-free gaming on both NVIDIA and AMD GPUs
  • 95% DCI-P3 color gamut coverage with DisplayHDR 400 produces vibrant, high-fidelity visuals beyond standard sRGB
  • HDMI 2.1 and DisplayPort 1.4 both support the full 240Hz at QHD, providing flexible connectivity for PC and console

👎 Cons

  • DisplayHDR 400 certification is edge-lit with limited local dimming — HDR content lacks the contrast depth of HDR600 or HDR1000 displays
  • IPS panel technology means black levels won't match VA alternatives, which is noticeable in dark game scenes and movie viewing
  • 27-inch QHD at 240Hz demands a high-end GPU (RTX 4070 Ti or RX 7900 class) to consistently hit frame rates that justify the panel
  • No mention of USB-C or KVM switching, limiting versatility for users who want to share the display between a gaming PC and a work laptop
  • DTS Headphone:X spatial audio via the 4-pole jack is software-dependent and won't replace dedicated audio hardware for competitive players

Frequently Asked Questions

Yes. It supports 240Hz at 2560x1440 via both HDMI 2.1 and DisplayPort 1.4, so you're not locked into one connection type. Both inputs deliver the full refresh rate without resolution compromise.
Yes. It carries official NVIDIA G-SYNC Compatible validation and supports AMD FreeSync Premium. Regardless of your GPU brand, you get tear-free variable refresh rate gaming without needing to choose sides.
The IPS panel covers up to 95% of DCI-P3 (typical), which is strong for a gaming monitor. It supports VESA DisplayHDR 400. While it's more than capable for content consumption and game visuals, dedicated creative work may demand higher-tier HDR and factory calibration.
The 1ms GtG spec reflects the panel's fastest pixel transitions on the IPS panel. In fast-paced titles, ghosting is minimal compared to standard IPS monitors, though VA panels still offer deeper blacks in dark scenes. The 240Hz refresh rate works in tandem with the response time to keep motion clarity high.
The product listing emphasizes panel specifications. Verify stand adjustability (tilt, height, swivel, pivot) in LG's detailed spec sheet for this model before purchase if ergonomic positioning is critical to your setup.
