Why can a coaxial cable carry hundreds of HD TV channels but a PC display cable can barely handle high resolutions?
Your DisplayPort cable actually has more total bandwidth, as much as 17 GHz. The difference is that this data is sent relatively *uncompressed,* that is, close to every pixel of every frame is transmitted. By contrast, cable TV is sent highly compressed, avoiding sending redundant data but requir…
The Short Answer
Your DisplayPort cable actually has more total bandwidth, as much as 17 GHz. The difference is that this data is sent relatively *uncompressed,* that is, close to every pixel of every frame is transmitted. By contrast, cable TV is sent highly compressed, avoiding sending redundant data but requiring more compute power and high-speed memory on each end.
