Monitor resolution Ubuntu Studio 18.04

Hello, I use my computer to edit videos and I just installed Ubuntu Studio 18.04 and it turns out that I lost a resolution mode of my monitors. Benq 24 “before Ubuntu 17.10 could reach 2560x1440 and now does not exceed 1920x1080. The same case happens to me with another monitor 42” in 4K, does not exceed 1920x1080. I followed the steps to extend this new resolution with the configuration of 2560x1440 in the modeline, but to be able to register it you have to edit a file xorg.conf, or the xorg.xonf, that does not appear in my system, someone could help. Thank you

I’ve moved this to the category because this site isn’t designed to take tech support questions. Sorry. I’d recommend using one of the official support channels listed on the page.
