Refresh rate issue on custom resolution

[Lord ruben]

I custom a 1280*720 144hz using CRU (custom resolution utility) and it works fine  . When I play VALORANT , I  find the custom resolution I have created , but the monitor shows only 120 when I play full-screen . If I change my resolution to windowed full-screen I can see the 144hz on my monitor but its windowed I get input lag and fps drop ingame .Is there a way to play VALORANT full-screen with my 144hz custom resolution ? (My monitor is asus VG248QG 165hz and laptop msi gf75thin 9rcx using a 2.1 hdmi cable.)

at fullscreen the game itself has to support that resolution

a number of games will cap at 60 FPS if they're in windowed mode, and will only go higher if run fullscreen.

at this moment the game says that I am running at 144hz but on top left the monitor says 120hz

no , that's why I used CRU to create the resolution here the list of the resolution that the monitor supports
