树莓派2b的HDMI设置在/boot/config的文件内,在此文件修改即可
配置如下:
hdmi_force_hotplug=1framebuffer_depth=32gpu_mem=448framebuffer_ignore_alpha=1start_x=0hdmi_drive=1hdmi_group=2hdmi_mode=87hdmi_cvt=1440 2560 48framebuffer_width=1440framebuffer_height=2560max_framebuffer_width=1440max_framebuffer_height=2560hdmi_ignore_edid=0xa5000080hdmi_pixel_freq_limit=400000000hvs_priority=0x32ffdisable_overscan=1#display_rotate=2config_hdmi_boost=4
最重要的就是hdmi_cvt的设置,其中48代表刷新频率,1440×2560的屏幕只支持48hz的如果设置其他的就不行,消耗一天才在Google上找到
