Cpu to far monitor

Assuming you are using DVI, the maximum recommend distance is 15 feet or 5 meters. 75 meters is excessively (15 times) beyond the recommended limit. It can be done, however, it will be expensive to do so.

Solution:
Gefen DVI DL Booster PLUS = $249 + the cost of the cable
- Support for 2560x1600 resolution
- Maximum range is 200 feet

75 meters = 246 feet

You will need to buy two of these devices for a total cost of $498 (excluding shipping & taxes) for your setup to work properly.

This is in fact the cheapest solution.

If you use VGA, you can get

It will extend a VGA connection (up to 1600x1200 resolution) over a normal CAT5 cable, up to a distance of 1000 feet. These gadgets actually work GREAT. We push 1280x1024 over one about 200 feet and it's clear and sharp. The nice part is that it's only $279, and you don't have to buy a super expensive extra long VGA cable to use them. Just normal CAT5.
