Port Gigabit
Could you recommend me a good gigabit router with at least 20 ports?
Pick up a router with a gigabit interface, then cascade it off a 24 port gigabit switch. See the link below for some options for the gigabit switch

What is DisplayPort
Displayport is one of the newer video digital interfaces that serve as a cathode ray tube, or CRT for monitors and televisions. Displayport is one of the Video Electronics Standards Association’s (VESA) newest vision in simplifying and standardizing video connections, including the common and much used VGA, DVI and HDMI interfaces.
The maximum capacity in transfer for a Displayport interface is around 8.6 gigabits per second over a 2m cable. The Displayport connector acts as a direct competitor with the HDMI, featuring richer colours, higher resolutions and being able to hold a variety of different channels which handle device control instructions.
This particular cable has been in the markets since 2008. While the original VGA port has been extremely reliable and compliant, the Displayport cable sets a new standard which is on par with the HDMI. Possible uses for the Displayport cable range from a home entertainment system to a computer monitor. The Displayport connection allows for a direct connection from the computer onto a digital entertainment system, greatly simplifying the process and cutting out any messy wires.
Utilising a USB connection supporting 1 of 4 pairs of data including audio, video, and clock signals, the Displayport cable boasts a maximum resolution of 1080p. Although the Displayport cable itself is compliant with other HD systems such as DVI and HDMI, the Displayport connector itself is not cross compatible.
Security measures implemented into the cable includes DPCP, or otherwise known as DisplayPort Content Protection. DPCP allows for users to optionally enable content protection that can help protect transmission data from being intercepted and sent to unauthorized users from a distance. The Displayport system is also being constantly upgraded, with its development backed up by Intel is releasing new versions to the market much like the way HDMI does so.
And in comparison, when looking at Displayport and HDMI, which one is better than the other? There are a variety of answers to this, but one advantage of using Displayport is that it is currently license free, meaning that developers and computer technology manufacturers are more likely to use the Displayport connector since it is more cost effective than the HDMI which requires licensing fees. In terms of quality, the Displayport would be more or less on the same level as a HDMI, which is by far one of the best means of display HD media. Displayport has received much positive feedback from the market, and it will probably continue to do so.
