很多玩家都会遇到游戏画面过扫描的现象，请教一下如何设置如下这些影响过扫描的参数？

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1
overscan_scale=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=16
#overscan_right=16
overscan_top=20
overscan_bottom=20

该用户已被禁言

#disable_overscan=1 关闭过扫描已开启
overscan_scale=1过扫描画面过滤已开启
#overscan_left=16 左边过扫描16个像素点
