Hello all,
You should take into account, that TV's are designed to be used as such: to watch TV shows and/or movies through DVD or Bluray. But when used with another (more complex as far as setup goes) source such as PCs the TV will act as a monitor, meaning to say, it will show the information sent by the PC's video card.
Depending on the TV's model, you will have certain compatible resolutions, and because of this, it will be able to display better (or not that great) picture, but the key part on this will always be the video card responsible of the image sent to the TV, and should be the part of the equation you need to focus at.
Certain cards, or drivers for that matter, will be able to display a cristal clear picture with just a little setup (if you find the correct one) and others will require some extra work by setting resolution, refresh rate, picture size, color management, etc. The bottom line is that the TV will only show what the card is sending, and not the other way around, and that's why you should focus in setting the correct outgoing image, other than trying to have the TV interpret a not correctly setup one. Keep in mind you should always start will the lowest resolution compatible mode and increase it until you get the best possible picture, while leaving the TV set to the standard options to avoid any conflict.
