Frequently Asked Questions
01 What type of panel does the LG 32GX870B use? ›
It uses an OLED panel, where each pixel generates its own light. This produces perfect blacks and near-infinite contrast — ideal for dark content and cinematic viewing. Response times are also extremely fast at under 1ms.
02 Is the LG 32GX870B good for competitive gaming? ›
✓ Yes. The 240Hz refresh rate is built for esports — it displays every rendered frame, reducing motion blur in fast games like CS2 and Valorant. The 0.03ms response time keeps pixels sharp between kills. FreeSync Premium Pro prevents screen tearing when GPU output fluctuates.
03 How good is the HDR on the LG 32GX870B? ›
OLED delivers the best possible HDR — each pixel switches off for pure blacks while bright highlights stay vivid. The contrast is effectively infinite, which is impossible to achieve with LED backlight panels. HDR films and games look exactly as intended.
