The MSI MAG 345CQRF E20 is a 34-inch 3440 × 1440 curved ultrawide gaming monitor with a 200Hz refresh rate, 0.5ms GTG response time, and Adaptive Sync, suited to PC gamers seeking smooth, wide-screen play.
Recommended For
- PC gamers who want a wide view in supported games such as RPGs and MMOs, and can connect over DisplayPort to use the monitor’s full 200Hz refresh rate.
- Racing- and flight-simulation players with a fixed desk setup who want a 34-inch, 1000R-curved screen for a more wrapped-around view.
- PC users who regularly keep several windows side by side—such as a spreadsheet beside a document or reference window—and prefer one wide display over a dual-monitor setup.
- Players who often game in a dim room and prefer VA-style contrast and deeper-looking blacks for dark scenes over the wider viewing angles typical of IPS displays.
Real-World Use Scenarios
- For PC games that support 21:9, the wide curved screen expands the view across the game world; connect over DisplayPort to use the monitor’s full 200Hz refresh rate.
- For racing and flight sims, the 21:9 view can show more of the surroundings at once, making it easier to keep track of the track, cockpit, or scenery without adding a second display.
- For work or study, users can keep two or more windows—such as a document beside a browser or chat—visible at once, reducing the need to switch between full-screen apps.
- When using a PC and another video source at the same time, Picture-in-Picture or Picture-by-Picture can show both inputs on the screen; the monitor does not include a KVM for controlling multiple computers from one keyboard and mouse.
- For console gaming, the monitor supports 1440p at up to 120Hz with variable refresh rate; it will not reach 200Hz over HDMI.

Reference Q&A
Q: MSI MAG 345CQRF E20 vs. MAG 345CQR: what changed?
A: Choose the MAG 345CQRF E20 if you want the higher listed refresh rate: it supports up to 200Hz, compared with 180Hz for the MAG 345CQR. Both are 34-inch, 3440 × 1440 curved VA monitors with a 1000R curve. The E20 is a modest refresh-rate step up, rather than a change in screen size or resolution.
Q: Is the MSI MAG 345CQRF E20 worth choosing over the Gigabyte GS34WQC?
A: Choose the MSI if you want a higher maximum refresh rate: it supports 200Hz, while the Gigabyte GS34WQC supports 120Hz natively or 135Hz overclocked. Both offer a 34-inch 3440 × 1440 VA ultrawide, but the MSI also lists swivel adjustment; the Gigabyte’s stand has height and tilt adjustment. The Gigabyte may suit buyers who do not need the MSI’s higher refresh-rate ceiling.
Q: Should I get the MSI MAG 345CQRF E20 or a 34-inch OLED ultrawide?
A: Choose the MSI if you prefer a Rapid VA panel and want to avoid OLED burn-in concerns from prolonged static desktop elements. Consider an OLED such as the Alienware AW3426DW if you prioritize OLED’s near-instantaneous pixel response and can accept its higher-end feature set and OLED-specific care considerations. The Alienware is also 3440 × 1440, but supports up to 280Hz versus the MSI’s 200Hz.
Q: Is a 34-inch 200Hz ultrawide like the MSI MAG 345CQRF E20 harder to run than a 27-inch 1440p monitor?
A: Yes. The MSI’s 3440 × 1440 display has about 34% more pixels per frame than a 2560 × 1440 display, so a graphics card generally has to render more pixels to reach the same frame rate. Choose the MSI for the wider 21:9 view and up to 200Hz; choose a 27-inch 1440p monitor if you want a lower rendering workload or prefer the standard 16:9 format.
Q: Is this monitor suitable for gaming?
A: It is designed for gaming, with a 3440 × 1440 ultrawide display, a 200Hz refresh rate, 0.5ms GTG response time, and Adaptive Sync. To use the full refresh rate, the computer, graphics card, connection, and settings must support it.
Q: Does it have built-in speakers or a webcam for video meetings?
A: No. The monitor has neither built-in speakers nor a webcam, so plan to use separate audio equipment and a webcam for video meetings.
Q: Is it useful for office work and multitasking?
A: Yes. Its 34-inch, 21:9, 3440 × 1440 screen provides room to keep multiple windows, such as documents and spreadsheets, open side by side. It has HDMI and DisplayPort inputs, but the listed specifications do not include USB-C or a built-in webcam.
Q: Can I mount it on a monitor arm?
A: Yes. It supports VESA 100 × 100mm mounting, so it can be attached to a compatible arm or wall mount. Check that the mount supports the monitor’s size and weight.
Q: Is the MSI MAG 345CQRF E20 suitable for both work and gaming?
A: It may suit someone who wants a 34-inch, 21:9 workspace and high-refresh gaming on one display. A Reddit buyer specifically asked about using it for work and PlayStation gaming, but the discussion offers little hands-on evidence. Note that the monitor has no built-in speakers, and its HDMI inputs support lower refresh rates than DisplayPort according to the product specifications.
Q: What are the trade-offs of this monitor’s Rapid VA panel?
A: The Reddit discussion identifies the main consideration: VA panels are often chosen for deeper blacks and higher contrast, while IPS may be preferable for viewing angles, color accuracy, or motion handling. This model’s listed 3500:1 contrast ratio may appeal to buyers prioritizing contrast, but the discussion does not establish how this specific monitor performs in those areas.
Q: Is motion smearing a concern on the MAG 345CQRF E20?
A: The available Reddit discussion raises smearing as a buying concern but does not provide a clear user-tested answer. The product is a Rapid VA monitor with a listed 0.5 ms GTG response time; those specifications alone do not confirm real-world smearing performance. If motion clarity is a priority, look for hands-on testing or buy from a retailer with a suitable return policy.
