34-inch · 3440 × 1440 · 175 Hz
A 34-inch 3440 × 1440 1800R curved QD-OLED monitor running up to 175 Hz on every input, with a 0.03 ms GtG response rating, DisplayHDR True Black 400 and USB-C display input with 15 W charging.

Specifications checked 21 Sept 2026Manufacturer specifications, not a hands-on test.
175 Hz at 3440 × 1440 over DisplayPort, HDMI 2.1 or USB-C, a 0.03 ms GtG response rating and 99.3% DCI-P3 (CIE 1976), plus a USB hub.
The 3-year warranty covers panel burn-in, and OLED Care 2.0 and a fanless cooling design are included.
USB-C charging is limited to 15 W, PIP/PBP isn't supported, and MSI gives no window size for its 1000 cd/m² HDR peak; typical brightness is 250 cd/m².

54 specifications in 10 groups. Values are manufacturer specifications unless a row says “Measured result” or “Calculated from cited specifications”. 1 row repeats a listed fact in the manufacturer’s own wording, kept under “Manufacturer wording”.
Manufacturer panel diagonal; rounded size printed on marketing imagery may differ.
SourceDisplayPort: up to 175 Hz; HDMI: up to 175 Hz; USB-C DisplayPort Alt Mode: up to 175 Hz, at native 3440 × 1440 resolution. Source, cable and selected mode must support the signal.
SourceCheck that your graphics card or console, input and mode support the listed technology.
SourceRequires a compatible source, port, driver and mode.
SourceCompatible source and cable required.
SourceSource port and cable must support DisplayPort Alt Mode.
SourceThe same facts in the manufacturer’s combined or original wording, each with its source.
GtG, MPRT and input lag measure different things.
SourceTypical SDR brightness; not an HDR peak figure.
SourceMSI does not state the window size or APL condition; not full-screen brightness.
SourceFigures above 100% describe colour volume, not coverage.
SourceThe datasheet footnote names CIE 1976 only for sRGB and DCI-P3; the Adobe RGB measurement basis is not stated.
SourceDisplayPort: up to 175 Hz; HDMI: up to 175 Hz; USB-C DisplayPort Alt Mode: up to 175 Hz, at native 3440 × 1440 resolution. Source, cable and selected mode must support the signal.
SourceUSB hub data needs an upstream connection to the computer.
SourceMaximum charging output, not the monitor’s power consumption. Compatible device and cable required.
SourceBoth the source port and cable must support DisplayPort Alt Mode.
SourceThe supplied stand has a published height adjustment range of 0–100 mm. This is travel, not the assembled monitor height.
SourceAdjustment travel, separate from assembled monitor height.
SourceMSI's datasheet prints the swivel range as “30° ~ 30°” (no minus sign), so the exact range isn't confirmed.
