HD is a misnomer ...used too often...to make products seem more expensive/valuable than they really are...
Rickie
So are we talking about pixel count? If so at what point is something considered hd? What about TFT COLOR.....does this affect weather or not a particular item is hd or not?
A thin-film-transistor liquid-crystal display (TFTLCD) is a variant of a liquid-crystal display (LCD) that uses thin-film transistor (TFT) technology to improve image qualities such as addressability and contrast.
Are the TFTs staggered or coplaner or inversed staggered or a combination construction?

TFT stands for thin-film transistor, and this variety of LCD represents the highest-end commercially available liquid crystal display screen. TFT is the technology used in televisions and computer monitors, though the latest crop of mobile phones and tablet devices also use TFT LCD displays.
However, not all TFT displays are created equal. If you need your*TFT display*for a certain function, if you're passionate about viewing angles and color brilliance, or if you just want to be in the know about LCD technology, you need to be aware of the many different types of TFT LCD displays.
Twisted Nematic (TN)*- TN displays are the cheapest type of TFT LCD displays. They have 6-8 bit color technology, and their max contrast when viewed straight on is 1000:1. When viewed from a 60 degree angle, TN displays only have 10:1 contrast. The max horizontal viewing angle is 60 degrees and the max vertical viewing angle is 15 degrees.
Multi-domain Vertical Alignment (MVA)*- MVA displays are a mid-range type of TFT LCD displays. With 6000:1 contrast, they improve upon TN technology, but they tend to be more expensive. The horizontal viewing angle is increased to 100 degrees while the vertical angle is 30 degrees, making it easier to use on a mobile phone or tablet that may be held and used at an angle. The max color quality of MVA LCD displays is 10-bit.
Super In-Plane Switching (S-IPS)*- Also known as Super-LCD displays, S-IPS displays rival AMOLED displays in terms of quality. They are a mid-ranged option that are less expensive than their LED counterparts, and they use significantly less energy than either TN displays or MVA displays. The level of contrast doesn't change as drastically with a wider viewing angle, though the contrast is comparable to TN displays. S-IPS displays offer near 180-degree vertical angle viewing and a stunning 150 degree horizontal angle viewing.

It is all about column and rows. A display is a grid of these cols and rows. Just like your telephone is a column and row. Take button one on a phone. That would be row 1 column 1. Button 2 would be row 1 column 2. Button 3 would be row 1 column 3.
Button 4 would row 2, column 1. Button 5 would be row 2, column 2. Button 6 would be row2 column3.
Understand the pattern?
Well that is how pixels are arranged, but just more complicated that a 4 row, 3 column telephone key pad. But, this is the jest of it.
If you touch a screen and it is soft, the it is a passive display. An active display would be hard (glass).
So when a a monitor reaches *VGA - 640 X 480 this were hd starts ?
HD is an ambiguous term. Not sure how it is relevant with sonar displays. HDTV resolution starts at 1280 x 720. I am using the term "start" loosely.
There is no finite definition of the moniker "HD"...(like Tom mentions above)...Quote:

It's all about brands competing to get your money...

In this picture theres 5 different views.5 different pixel counts.am l correct in saying all are hd and all are the same sharpness http://i826.photobucket.com/albums/z...ps6lbo5q9n.jpg
HD is a ambiguous term. The one with the most pixels (by definition) should be the "sharpest" per se. However, all pixels are NOT created equal.

These are the HB unit pixel densities per square inch...
The 798 has 31,170.5 pixels per square inch.
The 898 has 17,533.4 pixels per square inch
The 998 has 12,755.7 pixels per square inch
The 1198 has 8,858.2 pixels per square inch

Screen size has a big part to do with clarity/sharpness.Quote:

Here is the pixel math for all you high tech red necks!!!!!!
Theoretically, PPI can be calculated from knowing the diagonal size of the screen in inches and the resolution in pixels (width and height). This can be done in two steps:
1. Calculate diagonal resolution in pixels using the Pythagorean theorem:

- http://upload.wikimedia.org/math/a/1...7d51199426.png is height resolution in pixels
- http://upload.wikimedia.org/math/3/5...6fcd8a0387.png is diagonal size in inches (this is the number advertised as the size of the display).
