Timing positioning is accurate, because the differential signal switching is located at the intersection of two signals, rather than the ordinary single-ended signal depends on the high and low two threshold voltage judgment, thus affected by the process, the temperature is small, can reduce the timing error, but also more suitable for low-amplitude signal circuit.

I checked it with fsck, and the result was no longer available, so I had to reinstall it.Everything went fine, but I needed a dual-Screen Display (notebook and 22-Screen Display). First, check whet
