请问 D1s 用 RGB HV 通过 GM7123芯片 驱动电脑VGA显示，需要怎么配置呢？

[whycan]

;lcd_hv_clk_phase 0:0 degree;1:90 degree;2:180 degree;3:270 degree
;lcd_hv_sync_polarity 0:vs low,hs low; 1:vs high,hslow; 2:vs low,hs high; 3:vs high,hs high

这样配置：
lcd_hv_clk_phase = 0 / 1 / 2 /3
lcd_hv_sync_polarity = 3

显示器均提示无信号！

lcd_hv_sync_polarity 应该是配置 3:vs high,hs high
