Frame time issues are on the PC's end and should not be affected by the timing parameters.

Latency is a complex topic, but generally the timing parameters don't have a significant effect unless you increase the vertical blanking very high, which many monitors won't allow except at lower refresh rates. The refresh time is fixed based on the refresh rate, so increasing the vertical blanking would decrease the scanout time but increase the time between scanouts. Whether that would increase or decrease latency would depend on when the frame is updated and whether you're using vsync or not. G-SYNC/FreeSync is already optimized for latency.

The timing parameters themselves don't have an effect on image quality, but TVs and HDMI monitors might process TV-specific timing parameters differently from others, which can change the image, especially the color formats. This is usually not an issue with DisplayPort or DVI.

The timing parameters would only affect power consumption if the GPU is not clocking down the memory when idle because the vertical blanking is too low.
