My camera on my 2021 is very grainy and when I'm backing up to trailer it seems to not have enough light gathering to show the ball all the way to the trailer. Never had this issue with GMC so just wondering if there was some adjustment I can make with a setting or something.

2021 Lariat - no 360 camera.

 

Which trim level? I don't know if XL with smaller monitor has a lower definition camera or not. My '19 and even my previous '15 Lariat cameras have been plenty sharp to see hitch day or night. Can you include a photo of what you are seeing in your dash monitor?
