Higher ratedRanked #1 in Best Ultrawide Monitors

MSI Optix MAG342CQR

★★★★★4.5

$299

The MSI Optix MAG342CQR is a budget-friendly 34-inch curved ultrawide monitor that excels in gaming with its 144Hz refresh rate, 1ms response time, and deep blacks from its VA panel. While it offers vibrant colors and a sharp 3440x1440 resolution, its HDR capabilities are limited due to the lack of local dimming, and viewing angles show slight color shifts compared to IPS alternatives.

— Offers a 144Hz refresh rate and 1ms response time for smooth, fluid gaming motion
— Provides a 3440x1440 resolution with 21:9 ultrawide format for immersive gaming and productivity

Watch-outs

★★★★★4.3

$1,299

How they stack up

MSI Optix MAG342CQR

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.

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.
