Can i get rid of the borders on top and below the picture
In most cases you can remove those borders, but it depends on what source you are feeding to your tv and they way it's set up.
Here are a couple things you can try.
Look on your tv remote and press a button labeled either tv ratio, aspect, or wide. Im not sure exactly what it may be on your specific remote. Press that until you see the borders disappear. This will be called Full or wide zoom, but full is going to look the best.
If you cannot find the wide button on your tv, check the remote for your sat, dvd, or whatever source your feeding and go into the setup and change the aspect ratio to full. If you can provide the specific source your using, i might be able to provide some better detailed information
