It is about color options. 4:4:4 to 4:2:0 you loose 75% of the color information. 4:2:0 is good enough for situations and will be variable for people depending on eyesight, tolerance and equipment.

Saying DP is not an option is being lazy or out of ones budget. It certainly is an option just not one or many are willing to afford.
It's not laziness or not being able to afford it, a lot of people like me bought 4K TV sets this past couple of years when prices became more palatable (in my case a 2015 Sony Bravia 4K model) and to think that people would go out of their way and buy a new TV just because this card cannot output at 60Hz to their TV's HDMI 2.0 connectors and there simply aren't DP converters currently able to support this card does not make much sense and is not a very sound reason to invest almost $2K on a new TV. Mind you, this is a top of the line 2015 set from a well known manufacturer, and it doesn't have DP connectors on it, like the vast majority of existing 4K TVs out there.
I like gaming in my living room, but have full ATX systems on both my home theaters, so I'm not the target market for this card in particular, but people looking to build a killer mini ATX system will have to look elsewhere if they want to game at 60FPS at 4K
I still wait for the factual information that it would cost "a few cents" thats just blabla from you. You simply want to critizize AMD for not implementing it and you think yourself superior to a whole company - if someone like you can come to such an idea you dont think a company like AMD can? Your arrogance is just... wow. As on topic, other people already explained why they haven't done it, and my self opinion still is, a architectural change would have cost a lot more than a few cents. You're just wrong with your opinion.
As with Nano just being a "SFF card": you can see Nano as a air cooled Fury X too, with much more energy efficiency and only 5-15% less performance. Or with almost same power on same energy level (just raise the energy cap). It's more than just a SFF card, and the prizing is right. Also, you can take that Nano and mod it to have a stronger cooler, and just use it as an Fury X, with same specs, or with -50 MHz. That all being said, when you dont want that radiator/pump-thing, not everyone likes that stuff or has the space for it.
Am I arrogant because I'm just expressing my opinion on this card? I expressed my opinion in a respectful way and even used multiple links to validate it, when presenting a counter argument to yours. It is common knowledge such tiny chips as the ones found inside those dongles cost only cents to manufacture, how do you think you can find active converters for less than $10 dollars out there? Or any other electronic device powered by small processors that sell for a few dollars ?
Take this IC commonly found inside a DP to HDMI converter:

It sells for $0.10 when you order 100 or more from China:

So there, see? A few cents, satisfied? What's more, what do you think the actual manufacturing cost of a similar IC would be to AMD? Let's take adding more traces to the PCB into consideration, to place this 8x8mm IC between the GPU and the HDMI connector, do you think that adds a big chunk of money to the BOM for this card? Just think about it for a minute.
It's all about maximizing your profits by reducing costs, I'm pretty sure the BOM for Fury X is much higher than for the Nano, and yet both sell for the exact same price, does the fact that I point that out make me arrogant? I think not. Nvidia did the same with Titan X by saving a few cents and not adding a backplate to it, something the least expensive 980 featured out of the box from day one, and I called them out back then as well, both companies have a board of directors to respond to and a few cents here and there add up in the end when talking about your bottom line.
I don't even know you and never resorted to insults like you did from your first post, in my view you're the one who comes across as arrogant, funny how you just sidestepped the whole DP adapter topic you brought up in the first place, and yet you accuse me of not backing my argument, double standards much?
Oh, and btw, it's not me presenting this card as the king of SFF cards, it's AMD in pretty much all of their marketing presentations for the Nano so far.
I'm done with you, seldom have I had to deal with people who resorts to belittling and insulting others just for the sake of coming on top of an argument when I'm expressing my valid point of view, seldom have I used the ignore feature in the long time I've been a member of this forum either, as most people here are mature enough to discuss any given topic without resorting to insulting others, so I'm gonna take the high road and hope you learn to appreciate or at least respect the opinions of others.
Have a good day sir.
