Save $570 on LG’s 32-inch OLED gaming monitor that switches between 4K 240Hz and 480Hz
LG’s UltraGear 32GX870A-B is $829.99 at Amazon, saving $570 against the retailer’s displayed $1,399.99 list price. The 32-inch OLED monitor offers a choice between 4K at up to 240Hz and Full HD at up to 480Hz.
The US Amazon listing showed a new unit sold and shipped by Amazon.com when checked. The 41% saving did not require a coupon or membership, and delivery availability and price can change.
That dual-mode feature is the reason to look closely at this model. You get the sharper 3840 × 2160 setting for games where detail matters, then can switch to 1920 × 1080 for a higher refresh ceiling in faster competitive games.

One OLED screen, two ways to play
According to LG’s specifications, the panel measures 31.5 inches diagonally and uses OLED technology. The company lists a 0.03ms grey-to-grey response time and VESA DisplayHDR True Black 400 certification.
Switching to the 480Hz mode lowers resolution to Full HD; it does not run 4K and 480Hz together. Your graphics hardware, game settings and connection also have to support the mode you want, so the monitor’s maximum is not a promise that every PC can produce that frame rate.
LG lists NVIDIA G-SYNC Compatible and AMD FreeSync Premium Pro support for compatible systems. The appropriate graphics hardware and connection are needed for adaptive sync. Its stand supports height, tilt, swivel and pivot adjustment, with a 100 × 100mm VESA mount if you prefer an arm.

Connections and practical considerations
The monitor includes two HDMI inputs, DisplayPort 2.1 and USB-C with power delivery. That gives a compatible laptop a way to send video and receive power through one connection, though support depends on the laptop and cable.
OLED is attractive for its per-pixel control and deep blacks, but buyers who leave static interfaces on screen for long periods should consider the panel-care features and applicable warranty terms. LG lists pixel-care tools for its OLED displays.
The $570 reduction is measured against Amazon’s listed comparison price, not a verified price-history low. Check that the listing still shows the 32GX870A-B in new condition and confirm the final price and seller before ordering.
