First Impressions: A Week With the LG 27GX790A-B Gaming Monitor

Have you ever upgraded from a regular car to a sports car? That's exactly how switching to the LG 27GX790A-B Gaming Monitor felt after seven days of intense gaming, work, and media consumption. If you're considering a monitor upgrade that won't break the bank but still delivers professional-level performance, you'll want to read about my experience.


Unboxing Experience: First Moments Matter

The moment I pulled the LG 27GX790A-B from its box, I noticed the premium build quality. Unlike many gaming monitors that scream "gamer" with aggressive styling, LG took a more subtle approach with sleek lines and minimal bezels. The stand assembly was surprisingly simple - I had it up and running within minutes without hunting for the instruction manual.

The package included:


  • The monitor (obviously).
  • A sturdy metal stand.
  • Power cable.
  • DisplayPort and HDMI cables.
  • Cable management clip.
  • Quick setup guide.

Display Quality: Where It Truly Shines?

After connecting the monitor to my gaming PC, the first thing that struck me was the crystal-clear image quality. The 27-inch QHD display (2560 x 1440) hits the sweet spot between full HD and 4K, providing sharp visuals without demanding a top-tier graphics card.


Playing through Elden Ring and Starfield revealed details I'd been missing on my old monitor. From sweeping landscapes to dark dungeon corners, the HDR support brought environments to life with impressive contrast between bright and dark areas.


Gaming Performance: Speed When It Counts

Let's talk about what serious gamers care about - performance. The 1ms response time and 165Hz refresh rate aren't just marketing numbers; they translate to buttery-smooth gameplay with virtually no motion blur. Playing competitive shooters like Valorant and Counter-Strike felt significantly more responsive.


The AMD FreeSync Premium technology eliminated screen tearing without the performance hit of traditional V-sync. Even when frame rates dipped during intense gameplay moments, the experience remained smooth and consistent.



Beyond Gaming: Productivity and Media

While gaming performance is impressive, I was pleasantly surprised by how versatile this monitor proved for everyday work. The sRGB 99% color accuracy made photo editing and design work viable without needing a separate professional monitor.


The ergonomic stand with height, tilt, and pivot adjustments helped maintain proper posture during long work sessions. I could easily switch between landscape and portrait orientations when coding or browsing long documents.


Movie watching benefited from the vibrant colors and wide viewing angles. The built-in speakers are serviceable for YouTube videos, but for immersive gaming or movie experiences, I'd still recommend dedicated speakers or headphones.


The Little Things: Features That Add Up

Several smaller features impressed me throughout the week:

  • The on-screen control panel made adjusting settings intuitive without fumbling with physical buttons.
  • Black Stabilizer technology revealed enemies hiding in dark corners.
  • Dynamic Action Sync minimized input lag in competitive games.
  • The flicker-free technology reduced eye strain during marathon gaming sessions.

Room for Improvement

No product is perfect, and after a week, I did notice a few minor drawbacks:

  • The built-in speakers are adequate but not impressive.
  • The USB hub could benefit from more ports.
  • Some might prefer a more aggressive "gaming" aesthetic.

Value Proposition: Price vs. Performance

At its current price point (around $399-449), the LG 27GX790A-B positions itself in the mid-range gaming monitor market. After using it for a week, it feels like it performs like monitors costing $100-150 more. For anyone serious about gaming without wanting to spend flagship money, this hits a remarkable sweet spot.



Final Thoughts: Is It Worth Your Money?

After seven days with the LG 27GX790A-B, I can confidently say it delivers exceptional value for serious gamers, content creators, and professionals who need a versatile display. The combination of sharp visuals, responsive gaming performance, and thoughtful features makes this monitor a standout choice in 2025.


Whether you're building a new setup or upgrading an aging monitor, the LG 27GX790A-B deserves a spot on your shortlist. It balances gaming performance, visual quality, and everyday usability better than most competitors I've tested.
