      so I was able to move the lt side of the screen over so the text was not cut off but the rt side of the screen still has a black bar. I achieved this by adjusting the overscan settings in the config file of the sd card. I can adjust the config file to make the black bar on the rt bigger but I cant make it smaller. it seems like the cofig file wont recognize negative values. the overscan portion of the config file looks like this

      #uncomment this if your display has a black border of unused pixels visible

      and your display can output without overscan

      disable_overscan=1

      uncomment the following to adjust overscan. Use positive numbers if console

      goes off screen, and negative if there is too much border

      overscan_left=5
      overscan_right=-5
      #overscan_top=16
      #overscan_bottom=16

      why won't my pi accept negative values for the overscan?

      here's my setup
      I have a rpi 3 outputing analog rgb via gert 666 to a UMSA that outputs to my pvm2030;
      I downloaded the bulid sdimage from retropie version 4.1;
      the config code I used for to output 240p is

      dtoverlay=vga666
      enable_dpi_lcd=1
      display_default_lcd=1
      dpi_group=2
      dpi_mode=87
      #hdmi_timings=336 1 10 30 34 252 1 15 3 42 0 0 0 50 0 6400000 1 # 336:252 6.4MHz progressive

      ps. I do not want to adjust the pots inside my pvm; I have the pots just where I want them for all the original hardware (nes, snes,etc) I have hooked up

      pps. I have tried adjusting the x and y settings under the video settings of retroarch but it doesn't seem to do anything
