1. is a laptop with 1440x900 resolution and a intel HD onboard graphics card a HD laptop?
2. Are 1280x720 and 1920x1080 the only HD resolutions?
3. IF the true HD only has 16:9 aspect ratio does it classify 1600:900 as a HD resolution as well?

The reason I'm asking is because some people claimed that anything higher than 720p are considered HD but also some people think only 720p, 1080i and 1080p are the true HDs. Can any of the displays experts shed lights on these questions. Thank you.

Hi

1. In my opinion the term "HD" gets thrown around far to easy. numerous devices are coined as "HD" and only further down in smaller font fo they then specify "Full HD" or "HD ready". As far as I'm concerned, 1440 x 900 is not "HD".
2. as far as defined resolutions your question two seems to be correct that they are the only accepted "HD" resolutions.
3. I follow the reasoning on this one although I cannot find any evidence that it is accepted as "HD" resolution.
Snippet from Wiki:
There are currently four different labels: "HD ready", "HD TV", "HD ready 1080p", "HD TV 1080p". The logos are awarded to television equipment capable of certain features.

In the USA, a similar "HD Ready" term usually refers to any display that is capable of accepting and displaying a high-definition signal at either 720p, 1080i or 1080p using a component video or digital input, but does not have a built-in HD-capable tuner.
Here is the link to the full article - it contains other external links within as well.

I hope this copy / paste helps you.

Semantics.     A "true HD" panel is 1920 x 1080 ... although clearly a monitor that uses 16:10 aspect ratio instead of the HDTV 16:9 ratio and thus has a 1920 x 1200 panel is certainly "HD"

A 1280 x 720 panel is referred to as HD, but it's the previous generation, and in the TV world is not generally referred to as "true" HD

Obviously when you scale an HD signal (whether 720p or 1080p) to a display with a different resolution, there's some adjustment in the picture.    A 1440 x 900 display is a 16:10 monitor with higher pixel density than a 1280 x 720 panel => and will certainly display scaled HD signals (whether upscaled from 1280 x 720 or downscaled from 1920 x 1080) VERY well [Note that a 16:9 picture will scale to 1440 x 810 to keep it's 16:9 aspect].       It's NOT an "HD panel" => but neither is a 30" display with a 2560 x 1600 panel ... which is certainly BETTER than any HD panel based display.

Bottom line:   The 1440 x 900 panel you're looking at is certainly "high definition" => but it's not an HDTV panel.    It's a panel that was made for a monitor rather than a TV ... and has BETTER resolution than a 720 panel, and slightly less resolution than a 1080 panel.     The Intel HD graphics adapter will provide an excellent high definition picture on that display.

thanks for the replies, everyone.

Gary, more questions regarding to your answers.

1. if 1440x900 can up/down scaled HD signals, does that mean the quality of the image wont be as good? since the pictures are stretched out to fit the pixels.
2. if a none HD panel display (2560x1600) produces better quality than a HD panel. What is the purpose of the term HD??
3. Are you saying both 16:9 and 16:10 aspect ratios are considered HD in computer displays? if that's the case, 1440x900 is 16:10 so it should also be HD.

sorry if im asking dumb questions.

(1)  The picture will be fine -- nothing's "stretched" ... a 16:9 picture displayed on a 16:10 display simply has a small amount of unused display area at the top & bottom of the display.    TV signals are routinely scaled to fit displays => in fact, most HD broadcasts are in 720p, but they clearly look fine on 1080p displays.

(2)  "HD" is a marketing term.   It's come to mean the standard HDTV resolutions ... but ANY display with 720 lines or more of resolution is reasonably called a high resolution display.

(3)  The aspect ratio has nothing to do with whether or not a display is high resolution.    It's the pixel density.    ... 1440 x 900 on a laptop-size screen certainly has sufficient pixel density to be considered high definition.

is there a specific formula for resolution-to-laptopsize ratio to be considered HD?

I got a laptop that's 17" with 1600x900 native resolution. I scaled down to 1440x900 and it looks terrible. Does that mean 1440x900 on a 17" screen not have sufficient pixel desity?

You've changed the aspect ratio (from 16:9 to 16:10) -- you do not want to do that.   If you choose another resolution with the same aspect ratio (16:9) it should look fine.

There's no specific number that's "HD" => as I noted above, that's more of a marketing term than anything else.

ok one last question,

if there are 2 14" laptops, one with 1440x900 and the other one with 1366X768 HD 720p. Does the 1440x900 laptop produces better image?

Yes ... it's got a 23% higher pixel density.

However ... whether it's a "better" image depends on what you're using the laptop for.    If all you're doing is watching 720p videos, then it won't be any better, since you can't get a better image than the source material provides.

Don't worry about the term "HD" => as I noted long ago in this thread, that's just MARKETING.    Any modern laptop will display high definition material just fine.    Simply choose one with the features you like, and the highest quality display you can afford.
