The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the LG 27GX704A-B is positioned as the natural 1440p counterpart to the larger 4K OLEDs — same panel-class advantages (0.03ms response, TrueBlack 400 HDR, 240Hz refresh) at a meaningfully smaller size and price. RTINGS' broader coverage of LG's UltraGear OLED line consistently rates these panels as top-tier for PC gaming, and Best Buy listings cross-reference the model alongside LG's flagship UltraGear OLED options. Reviewer signal is thinner here than on the larger ASUS and Samsung OLEDs simply because the model is newer, but the spec pattern and Amazon's 4.6/181 verified-purchase rating align with what high-trust outlets have measured on sister panels.
What reviewers liked
- 240Hz OLED at 1440p with 0.03ms response is the spec consensus high-trust outlets associate with best-in-class motion clarity
- DisplayHDR TrueBlack 400 delivers meaningful HDR per general RTINGS coverage of LG UltraGear OLEDs
- G-Sync Compatible and FreeSync Premium Pro provide flexible adaptive sync
- 4.6/181 Amazon rating corroborates positive expert signal
Where it falls short
- Less independent expert-tier coverage of this specific SKU than older LG UltraGear OLEDs
- 27-inch 1440p means lower pixel density than 4K alternatives — reviewers note text clarity vs. IPS
- OLED burn-in risk on static UI elements is a recurring community concern
- Smaller screen size than 32-inch OLEDs for the same price tier in some cases

Reviewer signal is thinner here than on the larger ASUS and Samsung OLEDs simply because the model is newer, but the spec pattern and Amazon's 4.6/181 verified-purchase rating align with what high-trust outlets have measured on sister panels. Where reviewers caution: 1440p at 27 inches is a different value proposition than 4K — competitive players love it, but anyone doing color-critical work or heavy productivity may prefer higher resolution or a non-OLED panel that's safer with static content.
The synthesized verdict: if you want OLED motion clarity and contrast at a more accessible price point than the 4K flagships, and don't need the extra screen real estate of a 32-inch panel, reviewers point to this as a strong 1440p OLED choice.
