I said this in the last 4k TV discussion. I have a 60" 1080P set, and my couch is 8 feet from it, or 96 inches. According to http://isthisretina.com/ 60" 1920x1080 pixels should only be visible to the average retina up to 94". That 8 foot distance is about as close as I would want to sit to a TV that size anyway, so I lucked out there. If I got a 60" 4k TV it WOULD NOT LOOK ANY DIFFERENT at that distance. The 1920x1080 pixels are already just small enough to not see.
Now, go back to isthisretina and punch in 3840x2160 and 60" and what do you get? Yep, 47". Do you want to sit 47" from a 60" TV? Pretty sure you don't. I know I don't. You need to double the size to 120" in order to make the 8-foot viewing distance happen. But, again, do you want to sit 8 feet from a 120" TV? I don't think I would want to. Nevermind that an 85" 4k TV is something like $40,000! haha. How much would a 120" one be? Pff, yeah. That'll happen.
Also nevermind the fact that the last time you were in a movie theater with that big screen you were looking at a 4k picture. Did you see pixels during the movie? No. (And you were probably looking at a lot of 2k content during that movie anyway.)
TLDR: 4k is useless for the home, and always will be.
Not to mention, how much is a 120" 4K TV going to be?! 85" ones are over $40,000! haha. Yeah, that'll happen.
I have a 60" 1080P set that is 8 feet from my couch, or 96 inches. I actually fluked out, without knowing this in advance or even thinking about it at the time, in that a 60" 1080P image only has visible pixels at up to 94 inches away, beyond which point you're past the average retina capability. Punch in 1920 x 1080 and 60" at this site. http://isthisretina.com/
Not only that, but I don't think I would want to sit closer than 8 feet from a set that big, anyway. It's a pretty big image from that far away. Now, if you go back to http://isthisretina.com/ and punch in 3840 x 2160 and 60" and what do you get? Half of what you did before, or 47"! Sorry, but I do not want to sit 47" away from a 60" TV in order to appreciate all the pixels I would have paid for.
Now, extrapolate. If I wanted to continue to sit 8 feet from my TV, but I wanted a 4K TV that I could actually see (or nearly see) the pixels I paid for, knowing the information from above, how big would it need to be? That's right, 120" is what it would need to be. So we get back to the same problem again. I don't think I would want to sit 8 feet away from a 120" TV. But that's exactly what I would need to do in order to make use of 3840 x 2160 at that distance.
Maybe that wouldn't be too bad for watching movies, actually, but I doubt I would want to carry out my regular TV watching at that size/distance. I wouldn't mind trying it, but I am not confident that I would actually like it. Again, maybe for movies. Maybe.
They couldn't test for dropped and runt frames, and said so. So, the tests tell me nothing I want to know, other than I'll still be sticking with NVidia.
"That leaves us with Fraps. And of course, there’s no way for us to pick up dropped and runt frame using Fraps. So, we immediately shed the dual-GPU solutions from our charts."
Do they actually draw every frame yet? Can't exactly call it the fastest if they're still cheating. I'm looking forward to the pcper dot com review to see if they're actually doing what they're supposed to be doing yet. But only out of curiosity, as their track record means I'll continue buying NVidia. Go to the pcper website and look for the "Frame Rating: Eyefinity vs Surround in Single and Multi-GPU Configurations" article.
