How can you make cable TV picture quality more crispy does an HDMI cable help?

Answer 1

AnswerNo. HDMI would only help if you have the proper digital receiver from your Dish or Cable Company. If you, like the most of us, have your cable running from the pole outside, then into your house and straight to your TV... well there is nowhere to plug-in an HDMI cable. So, lets go with that for a second.

The first thing you can do is follow your cable into your dwelling. From there look and see if it runs into a small box, also known as a splitter. These boxes can go bad from time to time and are very inexpensive, and easy to change. If you don't see a clearer picture after changing the splitter, then you could have a bad line. This could be inside, but unlikely. If your cable is fuzzy and just goes off and on, then this might be the time you call your cable company. What could be happing in is, on the pole outside where your cable comes from, the cable company puts capacitors on your line to block the channels you don't pay for. Sometimes... often, these caps (capacitors) go bad. They will just come out and change it, and sometimes just take it off the line completely (this means free upgrade). Now, none of these things work for you then the next thing you could do before rewiring your house with new coax..... buy a inline amplifier. This will amplify the signal to your TV, making it clearer (most of the time). The higher the voltage the better the amplification and the clearer the image. If you have a really long run to your TV (100+ ft) that can cause resistance in the signal, also causing static or blurry picture quality.

Now, if you have a digital receiver and it has an HDMI connector this will make the picture clearer. ONLY, if you have a TV that will support HDMI and the resolution that the receiver outputs to. This brings up a whole new discussion.
