Overview

MSI's premium MPG series introduces the MPG 346CQRF X24, a 34-inch ultrawide gaming monitor that targets enthusiasts who demand both high refresh rates and immersive screen real estate. With a 3440×1440 (UWQHD) resolution, 21:9 aspect ratio, and a non-glare Rapid VA panel, this monitor delivers deep blacks and high contrast while maintaining a 240Hz refresh rate and 0.5ms (GtG) response time.
The monitor supports VESA DisplayHDR 400 for improved brightness and color in HDR content, and adaptive sync (FreeSync Premium / G-Sync Compatible) eliminates screen tearing. The stand offers tilt adjustment, and VESA 100×100mm mounting allows easy arm installation.
Positioned in the mid-to-high tier of ultrawide gaming monitors, the MPG 346CQRF X24 stands out with its combination of 240Hz refresh rate and rapid VA panel technology. It competes directly with models like the Dell S3422DWG and LG 34GP83A-B, offering a higher refresh rate at a similar price point.

Compatibility Guide

The monitor provides DisplayPort 1.4 and HDMI 2.0b inputs. To achieve the full 240Hz refresh rate at UWQHD resolution, you must use the DisplayPort connection. HDMI caps at 144Hz for this resolution. Ensure your graphics card has DisplayPort 1.4 or higher; NVIDIA GeForce RTX 30-series and AMD Radeon RX 6000-series or newer are recommended. Older GPUs with DisplayPort 1.2 cannot output 3440×1440 at 240Hz.
VESA mounting uses the standard 100×100mm pattern. The monitor weighs approximately 7.5 kg without stand, so choose a monitor arm rated for that weight.

Product Info

Released in late 2024, the MSI MPG 346CQRF X24 carries a street price around ¥78,000–¥80,000 (as of September 2025). Warranty is the standard three years from MSI (proof of purchase required). It is available through MSI's official online store, major electronics retailers, and Japanese online retailers.
Market positioning: mid-to-high tier. The 240Hz refresh rate and 0.5ms response time are standout features in this price bracket. However, HDR performance is limited to DisplayHDR 400, so users seeking a true HDR experience should look at models with DisplayHDR 600 or higher.

Best Use Cases

  • Competitive FPS and racing gamers: The 240Hz refresh rate and 0.5ms response time minimize motion blur and ghosting, giving you a clear advantage in fast-paced titles like Valorant, Apex Legends, or Forza Horizon. The UWQHD resolution provides a wider field of view. Not ideal for those who prefer 4K resolution or curved panels.
  • Productivity users and content creators: The 21:9 aspect ratio offers ample horizontal space for video editing timelines, spreadsheet comparisons, or multitasking with multiple windows. The 3440×1440 resolution provides about 2.4x the pixel area of 1080p. However, color accuracy is limited to roughly sRGB 100%; professionals needing DCI-P3 coverage should consider a different monitor.
  • Space-conscious users wanting a large screen: The flat panel design reduces depth compared to curved alternatives, making it easier to fit on a desk. VESA mounting compatibility allows for arm installation to free up desk space. Not recommended for users who prefer the immersive wrap-around feel of a curved display.

Things to Consider

This monitor uses a flat panel, not a curved one. While some users prefer flat screens for consistent geometry, the 34-inch width can cause eye strain as you need to shift focus to the edges. Curved alternatives may offer better viewing comfort for ultrawide use.
HDR performance is entry-level with DisplayHDR 400. Peak brightness is around 400 cd/m², which is insufficient for true HDR impact. If HDR gaming or movie watching is a priority, invest in a monitor with DisplayHDR 600 or better.
240Hz operation requires DisplayPort. Laptop users with USB-C (DisplayPort Alt Mode) should verify that their system can output 3440×1440 at 240Hz; some implementations may be limited to lower refresh rates.

FAQ

Q: Can I use this monitor with a PS5 or Xbox Series X at 240Hz?
A: No. The monitor's HDMI 2.0b ports support up to 144Hz at UWQHD, and consoles do not natively support 3440×1440. Consoles will output at 1920×1080 or 3840×2160 (downscaled). 240Hz is only achievable via DisplayPort with a compatible PC.
Q: Is the 0.5ms response time realistic?
A: The 0.5ms (GtG) is a best-case measurement; real-world performance is closer to 1ms. Still, it's significantly faster than typical IPS panels (4ms) and reduces motion blur in fast games. However, the difference between 0.5ms and 1ms is imperceptible to most users.
Q: Does this monitor have built-in speakers?
A: No. There are no integrated speakers. You will need external speakers or a gaming headset for audio.
