Can I take full advantage of HD quality movies on my 22" LCD, or do I need a bigger display?
I'm just wondering if it's worth having an HD player hooked up to my LCD or if I need a bigger screen to fully appreciate HD quality movies. Obviously a bigger screen would be nice, but I just want to know if the difference between normal DVDs and HD DVDs will really be noticeable on a screen of my size. Thanks!
Our eyes can only resolve HD resolutions at certain distances.
Standard DVD (and tube TV's) are 480p. 720x480 = 345,600 pixels
HD at 720p is 1280x720 = 921,600 pixels
Full HD 1080p is 1920x1080 = 2,073,600 pixels
There is also more color graduations and contrast over 480p at 720p/1080p resolutions.
I've always read the general rule of thumb for seating distances are as follows:
480p, sit 2 x the screen measurement away to not see the pixels. So on a 32" TV, sit 64" or 5.3 feet away.
720p, sit 1.5 x the screen measurement to not see pixels (but to see the improved resolution). So on a 42" HDTV, sit 63" or 5.25 feet away.
At 1080p, you need to sit only 1 x the screen size to not see pixels AND to see the full HD res. So on a 42' 1080p HDTV, sit 42" away, or only 3.5 feet for your eyes to notice all the resolution.
So, your 22" is a PC monitor at 1680x1050 ? You would probably have the screen only 2 feet away to really observe all the detail.
