Hi friends,

I have been wondering what the big hype about resolution & HD experience is. This high definition stuff requires the display to have either of these resolutions : 720p, 1080i, 1080p. That is, 1280 * 720 is 720p while 1080 refers to the 1920 * 1080 resolution.

This is a wide viewing angle resolution of 16:9 aspect ratio. HD also requires signal input through HDMI connection. This connection transfers both the video and the audio signals all digitally; no digital to analog conversion going on.

There is that alternate signal connection called DisplayPort that promises to transfer signals beyond HD quality requirements. However, you need to have the same type of connection on both the video card and the LCD. Trends show that consumer electronics are bent towards HDMI while computer devices are interested in using DisplayPort connectors.

On the other hand, wide viewing angled LCDs monitors typically have 16:10 aspect ratio. 24” LCDs have 1920 * 1200, 22” have 1680 * 1050 and so on. These LCDs can display HD resolutions 1080p and 720p respectively but with degraded experience of black bars at top and bottom of the movies.

Hope you find this useful. Share your thoughts as well.

Cheers!

Technology exists today to go beyond Full HD (1920x1080 or 1080p).

But I am not sure I fully understand what you are trying to say.

For everyday use. I am just sharing what i understand. Please explain what you mean as well. I was considering buying an HD LCD for myself, and came across these facts above. Would love to hear your thoughts too.

720p actually is 1366x720. But for some reason, even on wiki its 1280x720.

did u know there are TVs that have 3840*2160 res ??
I saw a video of some1 playing farcry 2 on that res !!

I saw this 720p version of the lord of the rings return of the king in a store in bangalore, it was too good

earlier we all used VGA cable (video graphics array) for computer
which were all analog signals
but nowadays HDMI is very common which is high defination multimedia interface which has a digital signal
and in monitors and GPUs we have DVI (digital visual interface)

so as the 720 p and 1080p represent the resolutions your TV can display
its the number or pixels which will be shaded
the more the better

720p(known as HD ready)-1366x768
1080p(known as full HD)-1920x1080
the greater the resolution the better and the more difficult it is for the GPU to support but TVs just come in these resolutions but computer monitors have even greater resolutions even 2Mega pixells
