LG UltraGear 27GS75Q-B 27"

Manufacturer: LG

The LG UltraGear 27GS75Q-B is a 27-inch gaming monitor built around an IPS LCD panel with a resolution of 2560 x 1440 pixels at 108 ppi. Designed specifically for gaming use, it features a 180Hz refresh rate paired with a 1ms response time, making it a capable option for fast-paced gameplay. The stand supports tilt, swivel, and portrait mode, and VESA mount compatibility is also included for those who prefer an aftermarket arm.

The display covers 99% of the sRGB color space and renders 16.7 million colors at 8-bit depth, with a typical brightness of 300 nits and a contrast ratio of 1000:1. Both Nvidia G-Sync and AMD FreeSync adaptive sync technologies are supported, offering flexibility across GPU platforms. Connectivity includes two HDMI 2.0 ports, one DisplayPort 1.4 output, and a 3.5mm audio jack, though there are no USB ports, no USB Type-C, and no built-in speakers. Operating power consumption sits at 28.92W, with standby draw of just 0.3W.

Pros

The 180Hz refresh rate combined with a 1ms response time suits fast-paced gaming where motion clarity matters
Simultaneous support for both Nvidia G-Sync and AMD FreeSync gives flexibility across different GPU setups
Stand adjustments include tilt, swivel, and portrait mode, allowing meaningful ergonomic customization
99% sRGB coverage at 8-bit depth provides consistent and accurate color rendering for the sRGB color space
VESA mount support allows the monitor to be used with a wide range of third-party arms and wall mounts
Standby power consumption of just 0.3W keeps idle energy draw very low

Cons

No anti-glare coating and neither a matte nor glossy panel classification may make screen reflections harder to manage in bright environments
The absence of any USB ports limits the monitor's utility as a desktop hub
HDMI is capped at version 2.0, which restricts bandwidth compared to newer port standards
No built-in speakers or audio features means external audio equipment is required
Color calibration is not supported, which limits accurate color adjustment for users who need precise display tuning
The EU energy label of F indicates relatively lower energy efficiency during operation

Who is this for?

This monitor is well suited to gamers who prioritize smooth, responsive gameplay, as the 180Hz refresh rate and 1ms response time together reduce motion blur and input lag in fast-paced titles. The dual support for Nvidia G-Sync and AMD FreeSync makes it a practical fit for users across both GPU ecosystems. The stand's tilt, swivel, and portrait mode adjustments also make it a reasonable choice for users who value ergonomic flexibility at their desk without relying on a third-party arm.

Who is this NOT for?

Users who need a monitor to double as a desktop hub will find the complete absence of USB ports a significant limitation. Those working in color-critical fields such as photo editing or graphic design may be held back by the lack of color calibration support, even with 99% sRGB coverage. Additionally, anyone requiring built-in audio output — whether speakers or Dolby-based decoding — will need to source a separate audio solution, as the monitor offers none of those capabilities.
