第一，先看下树莓派的GPU支不支持如此高的分辨率，常规是最高支持1080p，若采用2K分辨率，有可能会造成不可预测的BUG，比如黑屏无法开机，或是显示错误信息等
第二，可以在开发板启动系统前config.txt文件里面修改，但是有可能会造成不可预测的BUG

树莓派顶天只能支持1080p的分辨率，你这个是2k的，根本支持不了

如果硬要支持的话，需要你在编译镜像时就预先修改好显示参数，但是运行时很可能会开不了机

手里没有2k显示器

google 了一下发现有人在问
找到以下资料
对于21:9

HDMI_ASPECT_4_3 = 1
HDMI_ASPECT_14_9 = 2
HDMI_ASPECT_16_9 = 3
HDMI_ASPECT_5_4 = 4
HDMI_ASPECT_16_10 = 5
HDMI_ASPECT_15_9 = 6
HDMI_ASPECT_21_9 = 7
HDMI_ASPECT_64_27 = 8

对于2560x1080

max_framebuffer_width=2560
max_framebuffer_height=1080
framebuffer_width=2560
framebuffer_height=1080

您好,VideoCore IV GPU只支援1080P喔,大小可在Config.txt修改
