Can you log this as a bug ?

Include logs & configs from when you have the following...

1. No HorizSync & No VertRefresh & No modelines specified
2. HorizSync & No VertRefresh & No modelines specified
3. No HorizSync & No VertRefresh & modelines specified
4. HorizSync & VertRefresh & no modelines specified

Thanks,

Alan.
