I spend alot of time around digital video, hardly no time at all with photography. The best we got is 2560x1600 monitors, but generally, for video, we're in 1080p 2 megapixel land. I was wondering if photography could help me figure out just how much further resolution with TVs has to go before they just don't need to get sharper. I hear alot of 300 DPIs being tossed around, and I wonder if that's what's been determined as "it". Basically my question is how many pixels are enough. I know size of the image is a factor so lets take it to DPI. Lets use my screen as an example. My screen is a 24 inch 1920x1200 monitor, I think it's 90 DPI. It looks good, to be honest, 1080p doesn't look so great from where I'm sitting, it actually doesnt even look as good as a DVD does on a 50 inch from an average distance back. So where's the line drawn. I've got a 24 inch diagonal picture let's say. How many pixels do I need before adding a million more, or 10 million more, a billion more, just won't make a difference as far as a human being concerned. I guess this will help me figure out what quality I should have my 3D work printed as also.
