Unless it can do at least 60hz at 4k then no one should buy this. 30hz is ridiculously bad, even for desktop usage.

Just about all of these screens, with the exception of the first gen Seiki, can do 60Hz just fine. It's the computer, and interface, that struggle.

Not at 4k resolution. They all advertise themselves as 120hz, but that's only at 1080p. Show me a 4k monitor that is using display port 1.20 that is not at a ridiculous price.

A computer isn't going to struggle with that resolution for non-gaming usage. A $150 graphics card can easily handle 2x 2560x1440 monitors for desktop usage without breaking a sweat.

You're going to end up having to spend a lot more to run a single 4k monitor too because your graphics card absolutely must have display port 1.20 or hdmi 2.0 (which isn't even out AFAIK).

Something to keep in mind is that this is effectively a Windows monitor, not a Mac one. The reason for this is PPI: Most Apple displays are in the 100-110 PPI range, with Retina Display Macs doubling that to 220 PPI. At 28", a 3840 x 2160 panel has a PPI of 157, which sits right between Retina and non-Retina densities. This means that on a Mac, you’ll have to use it one of two ways: Either at 1x, where the higher PPI…

Can someone explain why this isn't just a continuous dial ? That is, why are there discreet "steps" in monitor scaling for these elements that you are talking about ? I would think that if I have 157 PPI or 220 PPI or 400 PPI that I would just adjust the dial to fit the element size I want. What's up ?

GTK on Linux uses Cairo and other vector rendering libraries to draw widgets and icons. You can set the font size or resolution as low or high as you like. This has been true on that system since before 2008 AFAIK.

Considering that every 3D game qualifies as an app that renders correctly under arbitrary multipliers, that argument seems a little suspect. The real answer is that there is an industry of designers accustomed to doing per-pixel tuning of their art assets and this work is worthless if the assets are going to be scaled anyway. Selecting integer multipliers (so far: "2") allows those assets to continue to render as des…

The real answer is that there is an industry of designers accustomed to doing per-pixel tuning of their art assets and this work is worthless if the assets are going to be scaled anyway. That's an effect, but not the cause – the roots of the raster-based paradigm of modern GUIs are far more technical. I would point to the tradeoffs between speed and memory limitations in early GUI systems: If you look at the original…

And yet Linux machines have been drawing SVG icons and SVG widgets for years. This limitation doesn't exist any more.

Look at Display Postscript, which was created by NeXT in the late 80s and carries through to much of Apple's Quartz rendering system today. Why are we still limiting ourselves to pixel graphics?

I'd suggest to drop the traditional speakers altogether and start using headphones. The industry standard Sennheiser HD650 or Audio Technica M50 will bring more sound quality for the buck from any loudspeaker I can think of. Of course, this is just an uneducated suggestion. Maybe you love to share your music.

He might work from home or in a private office, or these might just be for a home setup. I have AKG K550s for the office (I know I'm paying for the fact that they're closed) but bookshelves, a small amp, and a DAC for home. As comfortable and great as these headphones are, wearing them still fatigues me and I just don't enjoy having them on. I really enjoy speakers. In my college dorm, I had TCA WAF-1s with a TCA Giz…

Wearing AKG K550s do not cause any fatigue for me. Well, I guess one has to try before going all in on headphones. I personally don't like the sound from loudspeakers. Well there are some setups that I like but I have neither the budget nor the suitable place =)

By the way, don't your k550s also leak? However I adjust the pads, it still feels like everyone could hear what I'm listening. Never tested them by making someone else wear them but they feel not tight enough so never bothered to bring them to the workplace. I'm working in a shared office, so it really matters. Currently I'm using my M50s but k550s are so much better and if it's not as bad as I thought, I'd definitely use them instead.

I have a truly large head, so it's not really a problem for me. When I was reading reviews, there were plenty of warnings about improper sealing if you didn't have a large / certain shape head.

There's a decent noise floor in my office, and most of the other people use headphones. Even for the ones that don't, there's enough that my music isn't really audible. I'm also pretty vigilant about keeping my volume low, mostly for my own health.

Yes, but when you're actually working on a hi-PPI display, you can then lean in to view more detail, rather than zooming in. Much like we inspect things in the real world. As a photographer, this means a great deal. I can verify the sharpness of an image (a key component in deciding whether to keep it or chuck it) at a glance. Saves a lot of time.

Yeah, maybe...but there's still a practical limit. In order to see the pixels on a thunderbolt display (again, 109ppi) I have to get my face about 7 inches away from the screen. Closer than about 5 inches, and I lose the ability to focus because the screen is too close -- so there's a band of about 2 inches where I can gain from a higher pixel density than 109ppi, without losing due to eyestrain. And in any case, I'm…

I don't know whether it's due solely to the resolution, but I was pretty shocked to realise I can tell the difference between 300 and 600 dpi photographic prints (assuming there's enough detail in the image to do so, you need to print a 23 MP DSLR shot with high detail at a 7x10" print size to get there). I have had other photographers tell me that they don't see any benefit to retina screens at all... you're giving me the reason why here. :)
