i have bought a rtx 2070, and i connected to my acer gn246hl (144hz) with an one side displayport and the other side a dvi cable. i know that hdmi doesnt support 144hz. and i aslo know that you have to uipdat your drivers and remove the old ones. but im still with this 60hz on my nvidia contralpanel, i also tried to add a new refesh rate, i put 144hz and test it but then is says :no signal. So please if there is any one that can help me??, I WANT TO PLAY AT 144HZ. btw it worked with my old gtx970 card for a long time but after my new card it just shows 60hz option. pls helpme!?
