23.8-inch Full HD VA monitor with a 4000:1 contrast rating, up to 100 Hz over HDMI or DisplayPort, and a tilt-only stand.

Specifications checked 11 Sept 2026Manufacturer specifications, not a hands-on test.
The VA panel is rated at 4000:1 contrast, 1 ms MPRT and 113% sRGB, with both digital inputs running 100 Hz; an sRGB preset, HDMI CEC and Eye-Q tools are included.
Rear buttons provide menu control and custom shortcuts. The supplied stand includes a removable cable organizer and accessory slot.
MSI's feature page mentions D-Sub, but its manual and spec sheets show only HDMI and DisplayPort; check the connections if you need VGA.
The stand has no height, swivel or pivot adjustment, and MPRT requires above 85 Hz, disables Adaptive-Sync and locks brightness and response controls. There is no headphone jack, and MSI does not list built-in speakers.
The panel uses 6-bit + FRC colour (16.7 million colours), and there is no USB-C or USB hub.

SourceThe manual (W × H × D) and the UK 9S6-3BA9CH-050 specification sheet (W × D × H) both give 541.9 mm wide, 428.5 mm high and 182.0 mm deep. MSI's current specification page and global datasheet print the same numbers as 541.9 × 182.0 × 428.5 mm under a W × H × D label, but 182.0 mm is shorter than the 296.46 mm active-area height, so that label is treated as a transposition. · Manufacturer assembled dimensions with the supplied stand. Depth excludes additional cable clearance; this is not panel thickness.
