All resolutions work at 240hz but 1080

I have a HP Omen X27 1440p 240hz monitor. Every resolution I try works at 240 hz except for 1920x1080. At 1080 the refresh is stuck at 165. Every other game I play the 240 hz refresh works fine at 1080 so I'm coming to you for help since it seems like its an apex problem. I tried setting -freq 240 and -refresh 240 in the launch options(not sure which cmd would normally work), changing my desktop res to 1080 then launching the game, turning off all the adaptive sync option in nvidia control panel and in my monitors menu. I can't find the cmd in the config to set refresh. I'm not familiar with the source engines cmds. I could try making an autoexec but i dont know the cmd for refresh rate.
