Ok, correct me if I am wrong but I have to set the total horizontal lines so that the do clock equals or comes as close to but not over my display frequency. Since mine displays at 31.5 or 33.75 kHz I need to set it so the dot clock is as close to but not over 33.75 right?
From what I understand, if you are using a standard HD display and not a projector or multiscan monitor you must insure that the horizontal sweep frequency is equal to 31.5 or 33.75 kHz if that's what your monitor can handle. I believe that there are Powerstrip timings for precisely this.
My understanding is that the dot clock is representative of total bandwidth requirements and not horizontal sweep. The formula I have for calculating horizontal sweep is:
I am not an expert in this area. One of the HTPC gurus will have to give you the right answer but I believe that the closer you are to your monitor's actual scan rate the better the chances you will have of it staying in sync.
