Why does Hp (Hewlett Packard) ship analog cables with its digital computer monitors?

Computer technophiles respond please! I have a HP Desktop Computer and I am wanting to run 5 monitors?

• The goal is to have every TV in my house functioning as a remote monitor for my desktop system. I have bluetooth wireless keyboard/mouse to operate the desktop from any location, so know the task is figuring out the best way to connect each TV. I am running two 20" Gateway desktop monitors, a 37 inch Olevia LCD, a 42" Panasonic Plasma and a 52" Samsung LCD. The 2 gateways and the Olevia are in my home office, the 42" across the hall in my master bedroom and the 52" is in the lower level family room directly beneath my office. How should I go about making this happen? The CPU system was the best HP desktop you could buy off the shelf at CompUSA 1 year ago and they added an upgraded graphics card, but only 1 graphics card and my motherboard will not support 2 cards. What is the best way of integrating each one of my 3 additional TVs to my selection of monitors to use for remote computer access? What components, router, switches, cables etc will be needed? Drawings, illustrations?

• Answer:

  Your going to have a tough time getting this done but its doable. First of all due to the distance your going to have to either buy signal boosters for straight 15pin video or go with a video over CAT5. I think rather than having a few extra devices the video over CAT5 would be the way to go then convert back to your TV connectors from the CAT5. I enclosed a couple links and I wish you luck in this....
