The verdict

The Samsung Odyssey G9 offers an unparalleled immersive experience with its massive 49-inch 1000R curved screen and blistering 240Hz refresh rate, making it a top choice for sim racing and flight sim enthusiasts. However, its enormous physical size demands a dedicated setup, and the premium price tag limits its appeal to only the most dedicated gamers with the necessary budget and space.

How it compares

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.

MSI Optix MAG342CQR
#1 · Best Pick

MSI Optix MAG342CQR

4.5

The MSI Optix MAG342CQR stands out by delivering deep, inky blacks via its VA panel, a significant advantage over the washed-out contrast of the IPS-based LG 34GN850-B and ASUS ROG Swift PG349Q. While it lacks the infinite contrast of the Dell Alienware AW3423DW and the extreme size of the Samsung Odyssey G9, it provides a cost-effective alternative that balances deep blacks with a 144Hz refresh rate for budget-conscious gamers.

ASUS ROG Swift PG349Q
#2

ASUS ROG Swift PG349Q

4.5

The ASUS ROG Swift PG349Q distinguishes itself with native G-Sync support and a unique ergonomic stand, offering a reliable experience that avoids the burn-in concerns of the Dell Alienware AW3423DW. However, it lags behind the LG 34GN850-B in modern connectivity and brightness, and it cannot compete with the deep contrast ratios found in the MSI Optix MAG342CQR or the Samsung Odyssey G9.

Dell Alienware AW3423DW
#3

Dell Alienware AW3423DW

4.4

The Dell Alienware AW3423DW sets a new visual standard with its QD-OLED panel, delivering perfect blacks and infinite contrast that completely overshadow the washed-out IPS blacks of the LG 34GN850-B and the VA panel limitations of the MSI Optix MAG342CQR. Although it shares the 34-inch ultrawide form factor with the ASUS ROG Swift PG349Q, it offers superior motion clarity and HDR performance, provided the user can accept the burn-in risk that the LCD-based alternatives avoid.

LG 34GN850-B
#4

LG 34GN850-B

4.4

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.
