今天剛從亞馬遜哪裡弄回來了HDMI線和無線網卡,於是打算將輸出換到了HDMI,畢竟RCA那輸出實在看不上眼啊……雖然那種距離下用RCA更加能看清楚文字(手上只有電視有HDMI口,另外一個顯示屏有另外的人用,而且是沒有HDMI接口)。

換上了之後,打開電視,發現完全沒有輸出,我嘞個去,這搞毛?上網搜索一番之後,找到了一份config.txt的設定的詳細說明,仔細看了一番之後,稍微改動了一下,去掉了一些註釋,添加了一些修改。

在去掉這句的註釋之後

hdmi_safe=1

就發現HDMI有輸出了,但是分辨率依然慘不忍睹,只有可憐的500多x400多,於是繼續查下去,找到一些需要設定的地方

hdmi_drive 決定HDMI的輸出模式

hdmi_drive=1 DVI輸出,沒有聲音
hdmi_drive=2 HDMI模式,如果有聲音輸出並且被啟用的話就會有聲音輸出

hdmi_group 選擇模式分組,具體原理不明,根據這裡和下面的列表選擇分辨率

hdmi_group=1   CEA
hdmi_group=2   DMT

hdmi_mode 根據分組,下面分別有下列兩個表的效果

These values are valid if hdmi_group=1 (CEA)

H means 16:9 variant (of a normally 4:3 mode).
2x means pixel doubled (i.e. higher clock rate, with each pixel repeated twice)
4x means pixel quadrupled (i.e. higher clock rate, with each pixel repeated four times)

基本上設定好之後就沒問題了,系統自帶那改屏幕分辨率的東西實在不行呢~
