Question freesync display

Mar 17, 2019
Hi there im new here, was wondering if any of you guys can help out
i recently got myself an Lg 34um69g ultrawide with 75 hz and freesync and i also have a samsung 60hz 43 inch tv
the monitor is plugged via display port and the tv plugged via HDMI, with free sync off for the monitor i can have 2 displays with my LG monitor being the main or the number 1 display and the TV being the second one . but when i turn on the freesync on my LG it switches the display, the main display is now the TV not the monitor, if i unplug the HDMI TV though the main display goes back to the LG monitor. need your expert advice on this. thanks guys
