#26 is a suggest, I have implemented this function in the startup script of pp. What we need to discuss is whether it is necessary to integrate this function into pp_rk. What do you mean by fix?

The 1920x1080 screen modes supported by the monitor (use drm_info):

• [email protected] preferred driver
• [email protected] preferred driver phsync pvsync 16:9
• [email protected] driver phsync pvsync
• [email protected] driver phsync pvsync 16:9
• [email protected] driver phsync pvsync interlace 16:9
• [email protected] driver phsync pvsync interlace 16:9
• [email protected] driver phsync pvsync 16:9
• [email protected] driver phsync pvsync interlace 16:9

When not using the --screen-mode parameter, screen mode is well:
[email protected] preferred driver phsync pvsync 16:9

Before this patch, using the --screen-mode 1920x1080@60 parameter, screen mode is badly (interlace):
[email protected] driver phsync pvsync interlace 16:9

After this patch, using the --screen-mode 1920x1080@60 parameter, screen mode is well:
[email protected] driver phsync pvsync 16:9

This patch fix #44. Thanks!
