there is *NO* point in ANYTHING higher than that.
The general rule is that you should have at least 900 pixels per square inch on a print image for it to look good and that the Human eye can notice a difference up to (about) 10,000 PPI ...
Thus for a 60 inch television you should be able to see benefits of a resolution over 4800 x 3600 ...
Actually for a 24x30 the optimal resolution is closer to 50dpi.
I used to work in a photo lab, and I take pictures professionally. I dont know what you are smoking.
A 125,000$ fuji photo printer prints at about 600ppi.
If you are 6-12 inches from a picture. 300dpi is all you need.
If you are 3feet about 175dpi is all you need.
If you are over 5feet, about 125dpi is all you need.
The quality at the movie theaters suck tho. You want to have better than that at home.
I want 1,960,000,000,000,000x1080,000,000,000,000 on my 4inch portable.
The human eye can notice a diffrence up to about 10,000ppi? really? That would mean that you could see each and every pixel on your monitor from over 5feet.
DO NOT talk to me in image quality.
HOWEVER, if you are useing an injet printer, you need well over 1000dpi. However that dpi is not pixels per inch.

a 35mm camera's image quality is about 3-4mp. Right were 1080p stands.
Digital cameras have just started passing 35mm cameras in image quality.
If anyone has a web server willing to host a 6meg picture. I will show you what a 10.2mp picture looks like. and why you do NOT need NEAR that..
Poster size prints
Prints larger than an 8x10", also called poster size prints, are intended to be viewed from a few feet distance. Because of this, a lower resolution image will produce good results.
* 75 ppi - Poor to Fair
* 100 ppi - Fair to Good
* 150 ppi - Good to Very Good Recommended
* 200 ppi - Excellent
That is for a post print... bigger than 8x10.
I would say less than 150ppi is all you need.
oh yeah
I got there here.

EDIT: PPI is pixels per inch. 300ppi viewed from 6 inches looks perfect.
