Connecting monitor with resolution more than FHD

Hi
I’m planning to use my LG 25UM65 ultrawide monitor with 410c running as a home media center setup. Will 410c support 2560x1080 resolution or do I have to set the monitor to fHD mode? Since the monitor is 21:9, fHD will look kind of stretched

hi,

the HDMI output is provided by the onboard ADV7533 chip, which is a DSI to HDMI bridge. This chip cannot deliver more than 1080p, as far as I know.
