Ranked #5 in Best Ultrawide Monitors

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.
