投影屏幕撕裂变形问题

Other Parts Discussed in Thread: DLPA2000, DLPC3435

我使用DLPC3435与DLPA2000和IT6801FN做了一套DLP的驱动与解码板,驱动与解码连接后能够出现HDMI图像,但是分辨率不匹配的问题导致了屏幕闪烁或撕裂变形。

我的解码板能够连接720P的光机驱动,让其正确投影。我的驱动板连接720P的解码能够投影图像,但是图像是撕裂的。

我购买的光机是854*480的分辨率,和720P解码的分辨率不匹配,需要调整什么才能让电脑正确识别解码板的分辨率,并且正确解码?

想让IT6801解码输出854*480的信号需要在720P的解码基础上做哪些调整?

  • 你好。应该是DLPC3435的寄存器设置不对,可以参考以下I2C命令:

    Write Cmd:ImageCrop, addr:36, subAddr:10 00 00 00 00 56 03 e0 01;
    Write Cmd:DisplaySize, addr:36, subAddr:12 00 00 00 00 56 03 e0 01;
    Write Cmd:InputImageSize, addr:36, subAddr:2e 00 05 d0 02 ;
