How do i get my pc-screen to my Tv?

Should I return this tv, get a new dvd player, or see if we can still use the old tv?

• Last week my family purchased a Samsung, 32 inch LED TV. We thought it was time for an upgrade because we had had our old tv, a Sony Trinitron, for almost ten years. Even though the picture on it was immaculate it may have been damaged when we moved to our current residence more than a year ago. From the first day we plugged it in at our new abode the picture would constantly flicker from black and white to color, never staying on one shade. We tried changing the cable connection to see if tha had anything to do with it but to no avail. So we were very much looking forward to a tv we could watch, enjoying the steady flow of colors, not having to be interrupted by technical hiccups. When we plugged this television in the Comcast representative told us that because this was a hi def tv we would only get the best possible picture on the channels that were designated as HD. Once we got used to finding these channels we saw that the picture quality is pretty good, but there is still a red glare left on the picture in some instances that was not present when we looked at the tv at the store (we've since understood that the feed Best Buy uses for their tv's in their store is of the highest magnitude, so that explains the super-fine quality of the picture found there). Also, whenever we watch DVD's the picture quality is washed out, stretched, and just downright ugly to look at. With our old Sony tv this never happened. Is this because the qualities of the HD tv and the DVD's are not compatible with one another? If so, could a better picture for the DVD's be found by purchasing a new DVD player? It's extremely distressing because we watch some of our favorite shows on DVD, and through experiementation I've seen that the DVD's turn out clearer on our computer than they do in on the new tv we've purchased. We still have the old, previous tv and I've contemplated plugging it back in to see if the reception problem may have just been a loose cord that we didn't catch, because before this probelem started the picture quality on this Sony tv was 100% better compared to the new Samsung one we have purchased. In order to enjoy this quality we had on our old tv what should we do? Should we return this one and purchase a Sony tv, or simply purchase a tv that isn't LED? All of this has been immensely frustrating to us because we thought we were solving a problem that had been on our hands for a prolonged period of time by technologically upgrading to a superior pieces of equipment, instead, the more advanced tv seems to be performing less satisfactorily then our previous one did...I would greatly appreciate any advice anyone might be able to offer

• Answer:

  To get the highest quality picture requires the highest quality connection. Connection quality from highest to lowest is this: HDMI, Component (red, green, blue for video and red and white for audio). S-video and composite (the old yellow for video and red and white for audio). Therefore look at your comcast cable box and your dvd player. Check for which connections they each have and choose the best one to use from each to your new tv set. If you have an HD box from comcast there should be HDMI and/or component connections. I would use one of those. As for your DVD player, I would hope that it has component connections because that is the one you should use unless you have an upconverting DVD player that has HDMI output. If you do, then HDMI would be my first choice. Also, if your DVD player supports it, turn progressive scan ON.
