MSI MAG 346CQDF E20: Specs, Price, Pros & Cons
A 34-inch curved ultrawide built around a fast VA panel rather than the QD-OLED its similar-sounding sibling uses, and that single choice explains most of what follows.
You get the shape and resolution that make an ultrawide worth having, with contrast several times deeper than IPS at this price and a response time quick enough that the old VA smearing complaint is largely addressed on paper. What you give up is brightness and HDR entirely.

Editor’s note
The MSI MAG 346CQDF E20 is a 34-inch 1500R curved ultrawide built around a Rapid VA panel rather than the QD-OLED that the similar-sounding MAG 341CQP uses, and that single choice explains most of what follows. You get the 3440 x 1440 resolution and 21:9 shape that make an ultrawide worth having, with MSI rating the panel at 200 Hz, a 0.5 ms GtG minimum response and a 4000:1 native contrast. That contrast figure is the VA advantage: dark scenes hold their depth in a way IPS panels at this price do not, while the refresh rate and response time are fast enough that the old VA smearing complaint is largely addressed on paper.
MSI also gives it a dual-mode trick. Drop the resolution to 1720 x 720 and the panel runs at up to 400 Hz, which is only interesting for competitive shooters where frame rate beats detail, but it is there. FreeSync Premium handles tearing across the 48 to 200 Hz range, and there is picture-in-picture and picture-by-picture for two sources. The sheet lists 95 percent DCI-P3 coverage, which is good for a monitor without wide-gamut marketing, though the brightness is a modest 300 nits and the HDR Ready label means it accepts an HDR signal rather than displaying one convincingly.
Connectivity is the budget part. One DisplayPort 1.4a carries the full 200 Hz; the two HDMI 2.0b ports top out at 100 Hz at native resolution, so console or laptop users should know that going in. There is no USB-C, no USB hub, no KVM and no speakers, just a headphone jack. The stand tilts only, although the 100 x 100 VESA pattern makes an arm an easy fix. At 5.6 kg without the stand it is manageable on most mounts.
This is the ultrawide for someone who wants the immersion and contrast of a curved VA panel at a price well under the OLED alternatives and does not need the extras.

The bottom line
The MSI MAG 346CQDF E20 earns a VS Score of 35, trailing most of the 91 monitors we compare here, at least on the spec sheet.
- Who it’s for
- Gamers who want a 34-inch 1440p ultrawide with deep VA contrast and 200 Hz without paying OLED prices.
- Who should look elsewhere
- Anyone needing USB-C, a KVM, height adjustment or convincing HDR.
- The trade-off that matters
- Rapid VA gives 4000:1 contrast and a lower price, but brightness is only 300 nits and HDMI tops out at 100 Hz at native resolution.
- The main alternative
- MSI MAG 341CQP QD-OLED
