The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Poor picture quality on one tv channel

Zones: Miscellaneous, Miscellaneous Hardware, CRT Monitors
Tags: Television Cable
I dont subscribe to cable tv but I use the cable from the modem and split it going into my PC for internet and then a tv for shows.  The picture quality is very good for maybe 5 channels, with one channel (CTV in Canada) being scrambled and it has a ghost image.  I bought a TV card for my PC hoping it would get better picture quality as well as a small tv for the bedroom.  

Since I was splitting the cable now four ways between two tvs, pc for internet and pc for tv - the picture quality and internet quality went down big time.  Internet quality has always been a little flaky so I
bought a booster as seen here:

http://www.thesource.ca/estore/Product.aspx?language=en-CA&catalog=Online&category=VideoAmplifiers&product=1512506

Now everything is good.  Except for one thing.  The one channel (CTV) is still poor quality and unwatchable on the living room tv and the PC TV.  However on the small bedroom tv, the picture is fine (along with all the other channels).  Any reason why?  And is there any reason to fix this?

Here are some facts (when I refer to cable source I mean the cable booster which is connected to the main cable box on a 2 ft cable):

- The bedroom tv is the furthest away from the cable source (about 20 to 30 feet) and runs off one cable
- All cables are the same "high" quality cable (no dollar store brand)
- The PC TV is the closest and shortest link to the cable source
- Connecting the living room or pc TV directly to the cable modem doesnt improve the quality

So any ideas why a simple $100 14 in tv, outdoes a 500 living room tv?  Is there anything I can do?

The splitter may have been distributing the signal in an unequal way, but you connected the living room tv directly, so that's ruled out.  What is more likely is your small bedroom tv has a better tuner than the living room tv and the pc, as hard as that may be to believe.  There's nothing you can do except get a better tuner or boost the signal with a professional quality amplifier (if the signal was bad to begin with, this will not help).

What about regular TV antennas - Indoor only ones.  Could I really get a decent picture for 3 tvs (2 tv one pctv) with something like in the link?

http://www.thesource.ca/estore/product.aspx?language=en-CA&catalog=Online&category=Outdoor+Antennas&product=1518235

With an antenna connected to the cable booster - would that have any effect?

This is highly dependent on how good your over-the-air reception is - I have a cheap color TV that a friend was going to throw out, but in my bedroom the rabbit ears antenna picks up sharp reception.  You will have to experiment with your location to see if this is a workable solution, and it depends more on your location than on the kind of antenna you use.

>With an antenna connected to the cable booster - would that have any effect?

You can't mix a cable signal with an over-the-air antenna signal.
