Trying hdtv as monitor in i3 edition

Approximately a 40 inch diagonal screen with scaling turned off. Looks pretty good but could stand higher resolution but xrandr shows 1920x1080 as the highest. And it is already set at that. Relevant stats.

And 'card0-HDMI-A-1 is the big screen. Can I up the resolution, maybe? Thanks in advance!

Depends on the TV. If it's a 1080p tv, no.
What make/model tv is it?

It is, indeed 1080p. A Samsung. Thanks for the reply. Just went back to my dual monitor layout, which was fine.
