PC Gamer reported the MSI MAG 346CQ at Best Buy for $219.99, down from $289.99, during the October 6–7, 2026 Prime Big Deals event. That is a reported event price, not a guarantee the offer is still available: check Best Buy’s current listing, price and stock before buying. The 34-inch ultrawide pairs 3440 × 1440 resolution with a 180 Hz refresh rate, but its port limits and fixed stand are worth knowing first.
What was the MSI MAG 346CQ deal?
PC Gamer reported the MSI MAG 346CQ for $219.99 at Best Buy on October 6, 2026, reduced from $289.99. The report was tied to the October 6–7 Prime Big Deals event; it does not establish a current price or stock status. The article’s “cheapest” comparison applies to that event’s editorial roundup, not every retailer, seller, region or 34-inch monitor. PC Gamer’s deal report and event roundup provide the original context.
What does the MAG 346CQ offer?
MSI’s specifications describe a 34-inch VA-panel display with 3440 × 1440 resolution, 180 Hz maximum refresh rate and a 1500R curve. The ultrawide 21:9 format offers more horizontal workspace than a conventional 16:9 screen, which can suit expansive games and side-by-side windows, provided the game supports the aspect ratio.
- Refresh and response: MSI rates it at 180 Hz and 1 ms MPRT. MPRT is the manufacturer’s response-time rating, not an independent measurement of pixel transitions.
- Brightness and contrast: MSI lists 300 cd/m² SDR brightness. PC Gamer reports 4,000:1 static contrast and characterizes the brightness as modest. The VA panel’s stronger static contrast may come with slower pixel response than the fastest alternatives; that is a general performance trade-off, not a measured result for every use case.
- Adaptive sync and HDR label: MSI lists AMD FreeSync Premium and describes the display as HDR Ready. That label should not be read as evidence of a certified high-end HDR experience.
- Surface and mounting: The screen has an anti-glare surface and supports VESA 100 × 100 mm mounting.

#1 Best Overall
- Easily switch between different resolutions and refresh rates, allowing user to adjust settings based on the game
- Immerse in a captivating experience with a 1500R curvature rate
- Deliver ultra-fast response, low latency, and fluid motion clarity for smooth, blur-free gaming with exceptional responsiveness
- Eliminate screen tearing and choppy frame rates with 0.5ms response time
- Enhance eye-catching details through adjustments in contrast and shadows
Which connection supports 180 Hz?
Port choice matters if you want the monitor’s maximum UWQHD refresh rate. MSI lists two HDMI 2.0b inputs supporting UWQHD up to 100 Hz and one DisplayPort 1.4a input supporting UWQHD up to 180 Hz. For high-refresh PC gaming, connect over DisplayPort and confirm that your graphics card supports the desired resolution and refresh mode. Console and other source-device output limits may prevent reaching 180 Hz.
What are the trade-offs before buying?
The MAG 346CQ’s headline value is a large curved UWQHD screen with a high refresh-rate rating. Its practical compromises are less flexibility and convenience than some setups may need:
Rank #2
- Rapid VA Panel – Provides 0.5ms (GtG, Min.) response time, optimizes screen colors and brightness
- 200Hz Refresh Rate – Respond faster with smoother frames
- 0.5ms (GtG, Min.) Response Time – Eliminate screen tearing and choppy frame rates
- AI Vision – The new AI Vision technology can not only reveal details in dark areas but also enhance overall brightness and saturate colors
- Less Blue Light – Use a software solution to reduce the light emission in the blue-violet region of the blue light spectrum
- MSI lists no height adjustment. You may need a monitor arm or stand to position the display at your preferred height.
- There are no built-in speakers or USB ports, so plan for separate audio and peripherals.
- The included items listed by MSI are one DisplayPort 1.4a cable, one power cord and a quick guide.
- At 300 cd/m² SDR brightness, it may be less suitable for a very bright room than a brighter display.
How did it compare with other event deals?
PC Gamer’s October event roundup listed two other 34-inch UWQHD VA monitors. These are historical event prices, not live offers, and the models differ in refresh rate and curvature.

|---|---|---|---|
| MSI MAG 346CQ | $219.99 at Best Buy, reported October 6, 2026; reduced from $289.99 | 3440 × 1440; 180 Hz | VA; 1500R |
| Koorui 34E6UC | $229.99 at Amazon, listed during the event | 3440 × 1440; 180 Hz | VA; 1000R |
| Samsung Odyssey G5 34-inch | $249.99 at Amazon, listed during the event | 3440 × 1440; 165 Hz | VA; 1000R |
Brightness, port bandwidth and stand adjustability for the two alternatives are not stated in the cited event roundup, so compare current manufacturer specifications before choosing between them. Retailer prices and availability can change.

Who should consider this monitor?
It is a plausible fit for a PC gamer seeking a 34-inch curved UWQHD display and planning to use DisplayPort for high refresh. Before purchasing, confirm that your PC can drive the games you play at 3440 × 1440, that your desk can accommodate a wide curved screen, and that the Best Buy listing still shows a price and stock you want. If you need a height-adjustable stand, USB hub or built-in speakers, account for those separately or compare monitors that include them.
