AM3359输出1920*1080*60HZ信号,但是显示不居中

Other Parts Discussed in Thread: AM3359

hi,

我用AM3359输出1920*1080*60HZ信号, 用VGA模块实现D/A转换,连接到VGA 21" LCD显示器上,但是显示明显左上偏移.几乎50%的区域不显示.

 [2] = {                 .name = "VGA",                 .width = 1920,                 .height = 1080,                 .hfp = 44,                 .hbp = 148,                 .hsw = 88,                 .vfp = 4,                 .vbp = 36,                 .vsw = 5,                 .pxl_clk = 134810000,                 .invert_pxl_clk = 0,  },

 

感觉调整HFP,HBP,HSW,VFP,VBP,VSW应该不能到正常水平. 而且我感觉应该跟VGA D/A模块没有关系,能够显示出图像,就应该说明VGA D/A模块能够支持这么高的分辨率.

所以我想应该在什么地方调整,但是也不知道怎么入手.
