4 sources2 derived$1,051as of Aug 1

The LG 34GN850-B is a high-performance ultrawide gaming monitor praised for its fast 144Hz refresh rate, 1ms response time, and excellent color accuracy. However, potential buyers should be aware of its inherent IPS limitations, including low contrast ratios and occasional backlight bleeding issues. It remains a strong choice for gamers prioritizing speed and color over deep blacks.

Strengths
  • Delivers a fast 144Hz refresh rate with 1ms GtG response time for smooth gaming
  • Features an IPS panel with excellent color accuracy and wide viewing angles
  • Includes a 3440x1440 resolution that provides sharp image quality for productivity
Watch-outs
  • Suffers from low contrast ratio typical of IPS panels, resulting in washed-out blacks
  • Backlight bleeding and uniformity issues are frequently reported by users
Samsung Odyssey G9
Ranked #5 in Best Ultrawide Monitors
Samsung Odyssey G9
7 sources$1,999as of Aug 1

A 49-inch 1000R curved screen running at 240Hz makes the Samsung Odyssey G9 about as immersive as a monitor gets, which is why sim racing and flight sim enthusiasts gravitate to it. Its enormous size demands a dedicated setup, and the premium price limits it to the most committed gamers with the budget and the desk space to match.

Strengths
  • Massive 49-inch 32:9 curved display creates an incredibly immersive gaming experience
  • Ultra-fast 240Hz refresh rate ensures smooth motion with minimal blur
  • 1000R curvature matches the natural field of view for deep immersion
Watch-outs
  • Extremely large footprint requires a very deep desk and significant wall space
  • High price point makes it inaccessible for most budget-conscious gamers

How they stack up

LG 34GN850-B

The LG 34GN850-B offers a balanced mix of speed and color accuracy that outpaces the older connectivity and lack of HDR found in the ASUS ROG Swift PG349Q, yet it cannot match the perfect black levels of the Dell Alienware AW3423DW or the deep contrast of the MSI Optix MAG342CQR. While it shares the IPS panel limitations of the ASUS model regarding washed-out blacks, it avoids the massive desk footprint and extreme price tag of the Samsung Odyssey G9.

Samsung Odyssey G9

The Samsung Odyssey G9 dominates the list with its massive 49-inch 32:9 format and 240Hz refresh rate, offering an immersion level that the 34-inch models like the LG 34GN850-B and Dell Alienware AW3423DW simply cannot match. However, its enormous physical size and premium cost make it impractical for buyers who would be better served by the more compact and affordable MSI Optix MAG342CQR or the standard ultrawide form factor of the ASUS ROG Swift PG349Q.
