LG UltraGear OLED 32GX870A-B 32"

Manufacturer: LG

The LG UltraGear OLED 32GX870A-B is a 31.5-inch monitor designed for both gaming and photo or video editing use cases. Built around an OLED/AMOLED display panel, it delivers a native resolution of 3840x2160 pixels at a pixel density of 140 ppi, paired with a matte, anti-glare coating surface. The stand supports tilt, swivel, height adjustment, and portrait mode rotation, while VESA mount compatibility adds further placement flexibility.

On the performance side, this monitor runs at a 240Hz refresh rate with a 0.03ms response time, and supports AMD FreeSync Premium Pro, Nvidia G-Sync, and VESA Adaptive Sync for variable refresh rate operation. Connectivity includes two HDMI 2.1a ports, one DisplayPort 2.1 output, two USB ports, and a 3.5mm audio jack. The panel covers 1070 million colors, supports color calibration, and has a typical brightness of 275 nits. Stereo speakers are built in, and operating power consumption is rated at 56.3W.

Pros
  • The OLED/AMOLED panel combined with a 240Hz refresh rate and 0.03ms response time makes this a genuinely capable display for fast-paced gaming without motion blur
  • A 3840x2160 resolution at 140 ppi on a 31.5-inch screen produces a dense, detailed image well suited to photo and video editing work
  • Support for AMD FreeSync Premium Pro, Nvidia G-Sync, and VESA Adaptive Sync means the monitor works with a wide range of graphics hardware for smooth variable-rate output
  • The stand supports tilt, swivel, height adjustment, and portrait mode rotation, offering considerable ergonomic flexibility for different working setups
  • VESA mount compatibility gives users the option to use third-party arms or wall mounts instead of the included stand
  • Color calibration support is a meaningful inclusion for users working in color-sensitive editing workflows
Cons
  • At 275 nits typical brightness, the panel is on the dimmer side, which may be a limitation in brightly lit environments
  • There is no USB Type-C port, which rules out single-cable connectivity for laptops and devices that rely on that interface
  • The absence of PiP means users cannot display two sources simultaneously on screen
  • With no Ethernet or Wi-Fi, the monitor has no network connectivity of its own
  • Dolby Digital, Dolby Digital Plus, and DTS Surround are all unsupported, limiting the audio capabilities of the built-in stereo speakers
  • There is no ambient light sensor, so the display cannot automatically adjust brightness based on room lighting conditions
Who is this for?

This monitor is a strong fit for users who need a display that handles both competitive and immersive gaming and color-sensitive creative work at the same desk. The 240Hz refresh rate and 0.03ms response time suit fast-paced gaming scenarios well, while the 3840x2160 resolution with color calibration support and 1070 million color output addresses the demands of photo and video editors who rely on accurate, detailed imagery. The ergonomic stand with tilt, swivel, and portrait mode support also makes it practical for users who frequently adjust their setup or work across different orientations.

Who is this NOT for?

Users who work in brightly lit environments may find the 275 nits typical brightness insufficient for comfortable viewing, as the panel does not get particularly bright by modern standards. This monitor is also a poor match for those who depend on USB Type-C connectivity for single-cable laptop use, since that port is absent entirely. Additionally, users looking for network-connected smart display features, multi-source PiP functionality, or advanced surround audio from built-in speakers will find this monitor lacking in those areas.

Final Verdict
