What is the difference between Hd monitor and HDTV?

Answer 1

HD stands for High Definition. This term is misused constantly. HDTV is spesifically a digital TV signal in 720p, 1080i or 1080p. The number refers to the number of horizontal lines that make up the pictuire.

The i stands for an interlaced picture. Essentially the picture is drawn in two steps. First lines 1, 2, 5, 7 etc are drawn, then line 2, 4, 6, 8 are drawn. This gives very detailed and clear image, but could cause some jitter in high speed movement as the two fields in a frame are are slighly out of sync in fast motion.

The p stands for progressive scan. This means that each frame is drawn in one pass. However this also means that it takes twice as long for the image to refresh. In sports it means that each image is sharper and jitter-free, but the motion is not as smooth. Of course the average viewer really doesn't see much of a difference in normal viewing conditions. Double-blind surveys have proven this over and over. The differences are generally only noticed in conditions that most people will never have in their homes. But that is topic for another debate.

Though just about every HDTV on the market now supports 1080p, only some HD divices and specialty satellite and cable channels (not ones one would watch on a regular basis) provide this format.

For reference, standard definition picture on an old style TV was closest to 480i. (Analog 535 lines interlaced)

LCD stands for Liquid Crystal Diode.

LCD is one of the most common types of HD TV.

Plasma, DLP (Digital Light Prosessing), CRT (Cathode Ray Tube), and OLED (Organic Light Emiting Diode) are other types of HDTV. Each have their advantages and disadvantages. All provide a fantastic picture when fed a true HD signal.

With an LCD TV (which could be an HD TV or a Standard Definition TV (SDTV)), there is a light source (flourescent, LED, etc) that shines through a liquid crystal display to produce the picture.

Hi,

Monitors usually don't contain any tuners and require inputs directly to work. HDTV's have tuners.

Hope this helps,

Answer 3

A standard definition TV is only has 480 horizontal line going down the screen. A HDTV has 1,080 lines going down the screen. So on the HDTV the picture quality is better.
