Display line on the issue!

Users questions: Philips 170v7 when I monitor my D-sub cable is broken, I bought a new, but the computer does not recognize the display models, we can not identify the maximum display resolution, maximum refresh rate! This is how it? In this line will not display a damage? Display can be used normally!
Experts answer: that the general market to buy the factory line less than two lines (SDA and SCL), if less of these two data, the display does not recognize such a resolution. If fewer rows, the two field synchronization signal, the display will not show.
