Q: How to solve the shifted horizontal lines in 640x480?

A: 

The interlace problem only happens in 640x480 resolution, however, since version 5.4 is released, we have a new function called De-interlace to solve this problem. This function applied both main system and viewlog. Please follow these steps to apply de-interlace to your Main System:

1.Press Configure button in function panel, and select System Configure from menu.

2.In the System Configure dialog box, select Enable De-Interlace Render in Startup section.



3.Press OK to apply the setup.

4.Exit and restart the Main System. Without this step the function will not apply.

In the viewlog, you have to enable "use deinterlace render" for using this application.



You may use the De-interlace function to see the difference between De-interlace before and De-interlace after as in following picture.


De-interlace before:




De-interlace after



Note: The De-interlace function is only available when 640x480 resolution with single channel is used, also, you have to pre-install DirectX 9.0 and your graphics card supports the  De-interlace function. We recommend 128MB ram and at least an ATI 5200 or 9200se graphics card
