LG UltraGear OLED 27GX700A-B 27"

Manufacturer: LG

The LG UltraGear OLED 27GX700A-B is a 27-inch gaming monitor built around an OLED display panel with a native resolution of 2560 x 1440 pixels. With its glossy panel surface and 178-degree horizontal and vertical viewing angles, it delivers consistent image quality across a wide range of positions. The stand supports tilt, swivel, height adjustment, and portrait mode rotation, while VESA mount compatibility adds further flexibility for different setups.

Running at a 280Hz refresh rate with a 0.03ms response time, the display is designed to handle fast-paced content with minimal motion blur. The panel covers 1.07 billion colors and achieves a contrast ratio of 1,500,000:1, with a typical brightness of 335 nits. Adaptive sync support spans VESA Adaptive Sync, AMD FreeSync Premium Pro, Nvidia G-Sync, and Nvidia G-Sync Compatible certifications. Connectivity includes two HDMI 2.1 ports, one DisplayPort 1.4 output, three USB ports, and a 3.5mm audio jack, with standby power consumption rated at 0.5W.

Pros
  • The 280Hz refresh rate combined with a 0.03ms response time makes the display well-suited for fast-paced gaming where motion clarity matters
  • A contrast ratio of 1,500,000:1 alongside 1.07 billion colors allows for deep blacks and a wide tonal range across the panel
  • Adaptive sync support spans VESA Adaptive Sync, AMD FreeSync Premium Pro, Nvidia G-Sync, and Nvidia G-Sync Compatible, covering a broad range of graphics hardware
  • The stand supports tilt, swivel, height adjustment, and portrait mode rotation, offering considerable ergonomic flexibility
  • VESA mount support gives users the option to replace the factory stand with a third-party arm or wall mount
  • Two HDMI 2.1 ports and a DisplayPort 1.4 output provide multiple high-bandwidth video input options
Cons
  • The glossy panel surface without any anti-glare coating may cause distracting reflections in brightly lit environments
  • There are no built-in stereo speakers, meaning a separate audio solution is required for sound output
  • USB Type-C connectivity is absent, limiting options for single-cable setups with compatible devices
  • No Ethernet or Wi-Fi support is present, so the monitor cannot be used for any network-dependent smart features
  • PiP functionality is not available, preventing simultaneous display of multiple input sources on screen
Who is this for?

This monitor is well-matched for competitive and fast-paced gaming, where the 280Hz refresh rate and 0.03ms response time work together to keep motion rendering sharp and fluid. The broad adaptive sync compatibility — covering AMD FreeSync Premium Pro, Nvidia G-Sync, and Nvidia G-Sync Compatible — makes it a practical fit for users across different GPU ecosystems. Those who value ergonomic flexibility will also benefit from the stand's full range of adjustments, including tilt, swivel, and portrait mode rotation, alongside VESA mount support for custom desk setups.

Who is this NOT for?

Users who work in brightly lit rooms or near windows may find the glossy panel surface problematic, as it has no anti-glare coating and can produce noticeable reflections under direct or ambient light. The absence of built-in speakers, USB Type-C, and PiP functionality makes this a poor fit for users seeking an all-in-one workstation display that handles audio output, single-cable laptop connections, or simultaneous multi-source monitoring. Those looking for a display with smart TV capabilities, a front-facing camera for video calls, or network connectivity will also find this monitor lacking in those respects.
