i found this about dogs eye sight....i was close, but not accurate about televisions....
How dogs see
Dogs can see in much dimmer light than humans. This is because the central portion of a dog's retina is composed primarily of rod cells that "see" in shades of gray while human central retinas have primarily cone cells that perceive color. The rods need much less light to function than cones do.
Dogs can detect motion better than humans can.
Dogs can see flickering light better than humans. The only significance to this appears to be that dogs may see television as a series of moving frames rather than as a continuous scene.
Dogs do not have the ability to focus as well on the shape of objects (their visual acuity is lower). An object a human can see clearly may appear to be blurred to a dog looking at it from the same distance. A rough estimate is that dogs have about 20/75 vision. This means that they can see at 20 feet what a normal human could see clearly at 75 feet.
Dogs are said to have dichromatic vision -- they can see only part of the range of colors in the visual spectrum of light wavelengths. Humans have trichomatic vision, meaning that they can see the whole spectrum. Dogs probably lack the ability to see the range of colors from green to red. This means that they see in shades of yellow and blue primarily, if the theory is correct. Since it is impossible to ask them, it is not possible to say that they see these colors in the same hues that a human would. Whether or not the ability to see some color is important to dogs or not is hard to say.
Also consider the perspective that dogs see the world from. A dog with its eyes about 12 inches off the ground certainly sees the world a different way than a human with eyes about 48 inches off the ground like many 5th graders.
As humans we tend to think of dog's visual capabilities as inferior to ours. It is different but it may suit their needs better than possessing accurate color vision would.

ok...now for the cats.......
Cats can see TV and most cats do watch TV. They just don't like most people shows. The Nature Channel and Animal Planet type shows will sometimes catch your cats attention. Some cats may like sport programs that show rapid movement, like a Hockey game. There are videos made for cats to watch using various types of animals. Choose videos that have jerky movements and ALL nature sounds. Cats generally do not like "music" on videos while watching animals, as it can be distracting. Fish type videos usually do not work well, although a few cats may enjoy. Bird and small animal videos may work well with some cats. Bug videos work well because most indoor cats have encountered real bugs before, plus they offer more movement and can be filmed near real size. Be careful of videos that "zoom in" too much on birds or other animals. When the animals appear much larger than your cat, it could scare your kitty. Cats will remember things that scare them for a very long time and most cats frighten very easily.
Cat's like things THEY can capture, NOT things that can capture Kitty.
While watching TV, cats like to be at eye level, close to the screen. A stool or chair placed at "pawing" distance works well. If you try a video and your cat does not enjoy, try another.
Cats do have individual "tastes" just like humans. Cats also love variety.
Cats do not see the colors on TV as we do.
They appear to see Red colors as muted shades of gray.
This can cause a cat to not see some objects and animals, which is known as "Masking".
The picture of a TV screen is comprised of Red, Blue and Green dots. All colors we humans see on TV are created by mixing these three colors. Since cats cannot see red on TV, the color balance is much different for them. Cats will only see the colors produced by combining Blue, Green and Gray. Objects that are red or contain any red hues against gray, tan or brown backgrounds may be extremely hard for cats to perceive. If you were to adjust your TV hue or tint all the way to the green side, you would get an idea of what a picture looks like with no red hues. Although not exactly what a cat would see, it does illustrate how hard it is to see objects that were easily seen when red was part of the picture. That is why Kitty Show invented the "Serpia" Filter. It changes red colors and hues into primary colors cats can easily see.
It also "defines" outlines, particularly in the gray tones.
