TI中文支持网你好，ti的工程师:
我配置tvp7002为1920×1080 60分辨率，可显示到电视上没有满屏，感觉是行缩放了，调了几天 ，没点思路，希望能得到协助
下面是我配置寄存器：

你好，
我换了台电脑给tvp7002获取输出，屏幕可以显示满屏，分辨率都是1080p，都有根据“8637.tvp7002_THS8200_VGA_YPbPr_settings”配置，对比了寄存器如下图：
但是这俩台电脑都能正常满屏显示在 显示屏上，但经过tvp7002输出就是出现不满屏的现象（debug_tvp7002ok是能正常满屏，debug_tvp7002no是不满屏），对于了俩电脑显卡可以满屏的是HD Graphics 4400 ，不能满屏的是HD Graphics，已经有多台电脑出现不满屏现象， 不清楚这是tvp7002什么配置造成的，可以帮我解答下么？

回复 wj:
我已找到原因是我根据tvp7002_VGA to YCbCr 422 es 文档里面配置的是HV 和SV都是P极性，我用1440×900有俩种配置，我试下情况真的一样的，我查看了1920×1080是没有这个HV为N极性，SV为P极性的配置，是不是说明tvp7002是不支持这种格式的视频源做输入？如果支持要如何去配置？
