LG UltraGear 27GS75Q Power Efficiency and Display Review

In a country where "loadshedding" is part of our daily vocabulary, every watt counts. South African gamers are constantly balancing the desire for elite performance with the need for an energy-smart setup. What if you didn't have to choose? The LG UltraGear 27GS75Q enters the chat, promising buttery-smooth gameplay without punishing your electricity bill. This monitor aims to deliver the best of both worlds, but does it succeed? Let's dive into the LG UltraGear 27GS75Q's power efficiency and display performance.

A Closer Look at the 27GS75Q's Display Performance

First things first, a monitor lives or dies by its panel. The 27GS75Q boasts a 27-inch QHD (2560 x 1440) IPS display, which many consider the sweet spot for modern gaming. You get a significant jump in sharpness over 1080p without needing a top-of-the-line graphics card to push decent frame rates. ✨

The real magic for competitive players is the 180Hz refresh rate paired with a 1ms (GtG) response time. This combination ensures incredibly fluid motion and virtually eliminates ghosting, giving you a critical edge in fast-paced titles like Apex Legends or Valorant. Colours pop with 99% sRGB coverage, making everything from the vibrant landscapes of Tsushima to the gritty corridors of a space station look stunning. It's a testament to the quality we've come to expect from the fantastic range of LG monitors available today.

Analysing the LG UltraGear 27GS75Q's Power Efficiency

Now, let's talk about the rand-and-cents issue: power consumption. This is where the LG UltraGear 27GS75Q's power efficiency becomes a major selling point for South Africans. With a typical power consumption of just 33W, it's remarkably frugal for a high-performance gaming display.

What does this mean for you?

  • Less Strain on Your UPS: During loadshedding, a lower-wattage monitor means your Uninterruptible Power Supply lasts longer, giving you more time to finish your match or save your work.
  • Lower Electricity Bills: While one device won't slash your bill in half, every bit helps. Consistent, efficient energy use from your most-used peripherals adds up over a year.

Compared to older or larger 4K displays that can easily draw double the power, the 27GS75Q proves that top-tier gaming performance doesn't have to come with a high energy cost. If you're looking to build an efficient yet powerful setup, it's a smart component choice when you browse our full selection of PC monitors.
