raspbian配树老板家买的HDMI-》VGA，屏幕分辨设置求助

发表于 2013-5-18 16:00:32 | 显示全部楼层 |阅读模式

断断续续花费几个小时的时间，阻塞了两个多星期，分辨率还没配上去。
目前好像是640*480， X下好像也是这个分辨率。

OS是Raspbian系统，硬件是通过hdmi-》vga接个19寸的LED显示器。

不知有哪位达人解决过类似的问题，烦请指点1、2，这里先拜谢了。

下面是我config.txt文件的内容（只修改此文件就能将分辨率配好么？hdmi=16、19、35都试过，都不好用）：

# uncomment if you get no picture on HDMI for a default "safe" mode //cjl uncommented
hdmi_safe=1
hdmi_group=2
# uncomment to force a specific HDMI mode (this will force VGA)
#以下是计算机显示器使用的分辨率。
#这些分辨率的hdmi_group=2。
#hdmi_mode=1 640x350 85Hz
#hdmi_mode=2 640x400 85Hz //cjl uncommneted
# Set monitor resolution to 1024x768 XGA 60Hz (HDMI_DMT_XGA_60) //cjl added
# hdmi_mode=16
# hdmi_mode=17
# hdmi_mode=18
# 19 1024*768 85hz
hdmi_mode=19
# hdmi_mode=20
# 35 1280*1024 60hz
# hdmi_mode=35
# hdmi_mode=20
#另外一项“hdmi_ignore_edid”，是命令万博网页版登陆页派不检测HDMI设备的任何信息，只按照我们指定的分辨率输出。
#如果不加，万博网页版登陆页派可能仍会“自作聪明”的检测HDMI设备的分辨率，结果造成我们设置的分辨率无效。
hdmi_ignore_edid=0xa5000080
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan //cjl uncommented
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=-64
#overscan_right=-48
#overscan_top=-48
#overscan_bottom=-48
# uncomment to force a console size. By default it will be display's size minus
# overscan. //cjl uncommented
# framebuffer_width=1024
# framebuffer_height=768
# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1
# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
hdmi_drive=2
# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4
# uncomment for composite PAL
#sdtv_mode=2
#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800
