Key features: a 45-inch 5K2K (5120×2160) OLED panel with an 800R curve. The headline is its dual mode — switching between 5K2K 165Hz (for sharpness and work) and WFHD (lower resolution) 330Hz (for high-refresh competitive play), with a 0.03ms GtG response. HDR is DisplayHDR True Black 400, with ~98.5% DCI-P3 coverage. Ports include DisplayPort 2.1, HDMI 2.1, and USB-C with 90W power delivery; it supports both NVIDIA G-SYNC and AMD FreeSync. Unveiled at CES 2025, on sale within 2025.
Our take: the 45GX950A tackles an old conflict — big curved immersion and esports-grade refresh rarely coexist. Its dual mode is clever: run 5K2K 165Hz for story-driven games and creative work, then switch to WFHD 330Hz for lower latency in FPS and competitive titles. OLED's true blacks, near-zero ghosting and wide gamut, paired with DisplayHDR True Black 400, deliver contrast and immersion IPS/VA can't match; DP2.1 and 90W USB-C cover next-gen bandwidth and single-cable laptop connection. The trade-offs: this is a flagship — it's expensive; feeding 5K2K 165Hz demands a heavy GPU; OLED still carries some burn-in concern with prolonged static content (despite protections), and full-white highlights won't blaze as bright as Mini-LED. In short: for players who want one screen to cover both AAA immersion and competitive refresh, it's nearly dream-spec — provided your GPU and budget can keep up.
An honest note: 5K2K at high refresh is GPU-intensive, so assess your hardware; OLED still carries burn-in risk with prolonged static content (mitigations exist but can't fully eliminate it). Pricing, availability and warranty follow LG's regional sites.
Pros
- Dual mode: 5K2K 165Hz immersion / WFHD 330Hz esports in one screen
- OLED true blacks, 98.5% DCI-P3 and True Black 400 deliver top-tier image
- DP2.1, HDMI2.1 and 90W USB-C cover bandwidth and power
Cons
- 5K2K high-refresh is very GPU-intensive
- OLED still carries burn-in concern with static content
- Flagship positioning means a high price
