Not sure if the title is correct but some games ill put at 2k on the main screen and it'll show to game for a second then the display will say it has no signal. it only does this after alt tabbing normally. If i turn off the display, it'll pop up on the other window and only does it in fullscreen, not in fullscreen window. Im running an RTX 2080 with 16 gigs of ram and an i7 7700k cpu. the display is an Asus TUF gaming VG27AQ. Any ideas why it does this?
