I have a newly bought cheap 8 inch TFT LCD display that is "cutting the edges off" on all sides (i.e., not showing all the pixels). I've come to understand that this is due to "overscan" which seems to afflict mainly TVs using HDMI input.
My kernel is first booting up into efifb and then switching over to inteldrmfb -- both frame buffer drivers exhibit the issue. I am not using X windows and will never want to use X on this tiny display. All I am wanting to do is use the Linux text console. So any solution using "xrandr" is out.
I have tried everything I can find regarding driver-level (kernel-level) frame buffer settings to solve this problem, including tweaking the resolution settings with the "video" kernel boot parameter and by tweaking the timing settings post-boot with fbset, but no matter what I do with fbset, it seems to be ignored.
So my question is this: Is there a way, perhaps higher level than at the frame buffer driver level, that I can add margin around the frame buffer console?
I know I can use "stty" to shorten the number of columns and rows that Linux will use on the console, but that will only solve the issue on the right side and the bottom side and still leave characters cut off on the left side and the top side. Is there a way to use "stty" to add a "first column" and "first row" offset to the console (i.e., some whitespace padding)? If not with stty, with some other light-weight tool (not X windows)?
