That's a "no true scotsman" argument. I don't think I have to prove that upsampling a low-res image produces inferior quality to a native-resolution or resized/cropped high-resolution image. But "acceptable" is in the eye of the beholder, and you will simply move the goalposts. No-True-Scotsman is an impossible argument to win and I'm not going to engage it. Most people would find a VGA-res camera "acceptable" for their facebook snaps, especially after upsampling. So when can I expect you to sell your gear and purchase a first-gen digital camera?
It's inferior to what's possible if you're not buying low-quality gear, and that's all that needs to be said.
And I say this as a person who owns a 16mp APS-C camera. That sensor's pushing 5 years old at this point, it definitely belongs in the "budget-conscious" price range. I paid <$200 for mine a year ago, if it were $1000 today I would look at stepping up to a D600 instead.
Quote: Believe it or not I already use a 2700x1400 screen. 4k is only 50% more pixels. The 2700 monitor is mostly used for keeping multiple windows open and editing photos. There's not a thing I can think of out there that would inspire me to buy a 4k monitor. I was offered one a few years ago for around $800. I passed. And so are a huge number of other people, for many years to come. it's adoption as a standard display standard is a long way off IMHO.
Seiki's 39" 4K TVs (30hz) can be had for $330 any day of the week, and they often go on sale for 25% off. Even without the sale, that's price-competitive with 1080p panels - the #5 seller on Amazon right now is a 39" 1080p for $330.
If you want a 60hz screen they run a bit more, but they're coming down fast too. Newegg had a deal a while back, $600 for a new Samsung U28D590D (28") bundled with a Samsung 840 EVO 250gb (roughly a $150 item at the time). So something like $450 on sale. And you can pick up a refurb U28D590D for $500 right now. Conversely if you picked up a brand new 28"1080p screen it would run you $275-325. You're looking at a $150ish bump in price to quadruple your resolution.
4K offers a significantly higher PPI than 1080p screens. High-PPI displays look great, it's what makes Apple's Retina displays sell like hotcakes. You yourself may not be able to see the difference, different people have different visual acuity and different quality standards. But it's no longer an extravagant expense, they're getting to be pretty cost-competitive and will continue to decline as manufacturing capacity switches from 1080p to 4K.
Personally the only 1080p screen I would buy right now is a 24" monitor that I could get refurb'd for $100-125. Buying new? Nah, spring for the Retina display. If you're not gaming 30hz probably isn't even a big deal, and that's enough resolution on a 39" to be workable as a monitor.
If I had a nickel for every time someone on this forum poo-poo'd having the option to buy technically superior gear, I would have an awful lot of nickels.
