A:Answer There aren't a lot of differences. Both monitors have the same resolution and brightness, as well as the same response time. Both have a VGA and and HDMI 1.4 port and the same color gamut. The only obvious difference is that this monitor has standard VESA mounting points on the back while the M271 does not. That means that this monitor can be mounted on a monitor arm or even a wall, while the M271 can't.
