I use a 49" ultra wide monitor 5120x1440 32:9 resolution. I'm able to change the resolution to 5120x1440 in project settings and then my preview will be full screen without any black bars. However when I go to render, I'm unable to adjust to 5120x1440 in ANY of the rendering presets. So when I do render it makes my videos fully widescreen with massive black bars above and below the video. These black bars even show up on my other devices, not just my ultra wide monitor after rendering.
I'm running a Intel I9-12900k, MSI B660M Mortar motherboard, Nvidia GTX 3060TI, 64 Ram and 850Watt power supply. So I know my computer has more than enough potential to render under these settings. Someone please help.
