Yep, it's a crapshoot, but I think I'm going to pull the trigger soon on one of these anyway. Can you tell me which of the usual suspects (green-sum, hulustar, bigclothcraft, etc.... you went through?
What exactly was your problem, completely dead panel or massive backlight bleeding?
Just checked the order and it turns out we got two Nixeus WQHD 27" @$450 in August of 2012. After about 6 months we had one panel completely die which we RMA'd and received another one after a decent expense shipping. Shortly after the RMA the second panel we purchased died in a similar fashion. We currently have one that works and are not going to bother with RMAing the other dead panel.
Maybe I should have phrased it better, a 27" 1440p screen is only around 110 PPI. Hell, a 32" screen like this is still only 140 PPI. I'm waiting on either a 1440p screen at 19" (which is over 150 PPI) or a 4k screen at 29", those have pixel densities I don't notice greater precision at at around a meter / yard.
What's important is that we're starting to see movement in high-end resolutions for the first time in quite a while. The arrival of 1080 HD screens created a long term set point in the market that brought progress to a bit of a halt.
But I'm paid to look at text, not watch movies.
It's nice to have real estate, but my eyes are crappy and I would dearly love resolutions to start getting denser again so I can use smaller font sizes without going crosseyed.
It used to be that monitor resolutions trickled down from the top. Now, thanks largely to Apple, they're trickling up from the bottom. But this is movement at the high end. In a few years I can imagine buying a 4k ~27-30" monitor to replace my current 30" monitors.
I wonder if there's some way to use eyetracking and headtracking to fake an enormous display with extremely high DPI. Only a very narrow area of the eye is actually focused and can detect features with maximum fidelity.
I vaguely recall Intel or MSR were doing research on something related -- dynamically changing LOD on 3D scenes to give more processing to where the eye is currently focused.
Bruce Tognazzini described a similar idea from research at Sun in his book Tog On Software Design from 1995: future computers would have print-quality DPIs, and would blur or scramble areas of the screen that were far enough outside the fovea for privacy.
The article also mentions they needed to enable DisplayPort 1.2 MST for the full 60Hz refresh rate, so I'm inferring that the monitor might be detected as two screens (a left-right split). If someone has more info on 4Kp60 and displayport, please chime in.
Note that both nVidia and AMD support MST on their major products, including AMD APUs if the motherboard has displayport.
I'm running Debian Wheezy on a Chromebook Pixel (2,560×1,700 at 12.85 in, or 244.28. Intel HD Graphics 4000) and it works great.
If Intel GPUs can drive a screen that large, then I strongly suspect that Linux will as well. Intel support in Linux appears to be more or less on par with Intel support elsewhere.
> The only question would be the sheer number of pixels on the screen.
Which on Linux is a big, big question. My experience is that a 2x2 array of 2560x1440 displays is simply not reliable under Linux. The same worked fine with Windows. The total number of pixels is one factor that seems to trip up Xorg (or something); the above setup had a total resolution of 5120x2880, yet a 1x3 array totalling 4320x2560 worked fine. This was last year, on multiple machines with various graphics cards (but just one card in a given machine).
So I don't know why, but it seems that somewhere between 4320 and 5120 linear pixels, or between 11 and 15 total megapixels, Xorg or some other part of Linux (but probably Xorg) has problems. This Asus screen is 3840x2160 which means two of them together (16.5 MP) will likely not work (there's a chance if they're oriented vertically so the max linear resolution is 4320), and three in any configuration is very likely to fail.
Using many displays and getting very high resolution on Linux has been a bad situation for a long time now. Some hardware configurations just won't work (but are fine with Windows); others will hard-lock sometimes; still others will mostly be OK but once in two weeks freak out and spew artifacts everywhere. It's a real mess, and nobody seems to "own" fixing it.
One problem with using the Seiki for a PC monitor is a maximum 30Hz refresh rate at that resolution. However you won't notice the difference between a 30Hz display and a 60Hz display unless playing video games. Movies are 24hz and tv shows are 30hz (25hz in the UK). I have a lot of experience using one of those old Viewsonic 3840x2400 monitors (same as IBM T220) which also ran at roughly 30Hz.
I think the Seiki would make a perfect monitor if it were only 40" - I love my 30" + rotated 24" set up now. Apparently a 39" version is due any day now. Model number SE39UY04. MSRP $700.
On a personal note... I've waited a decade for higher dpi monitors to become mainstream. Just in the last year or so I've noticed my near-field eyesight starting to go. Ironic for me that just as these things start to show up, I start to become less able to use them.
The 39'' version of the 4K monitor you mention seems to be at Amazon right now for $700. I'd be interested to know if this works as an external monitor (in clamshell mode) for a MBP running OSX. I understand that it won't work as an additional display.
This size seems a bit overwhelming for use as a monitor. (I used to have a 30" display but got rid of it because it was too imposing on my desk.). It's still nice to see this as an option. It should be good for visualization of large data sets.
The problem seems to be latency. TV aren't meant to be interactive as much as PC monitors are. Especially at a high resolution like this, you will notice a lag between the time you perform an action and the time the TV renders it.
Reports are that lag time on the seiki is pretty small because it has the most bare-bones of image processing. Crummy video processing (especially the primitive upscaling from 1080p to 4K) is a problem for a TV but actually a benefit for a monitor.
However you won't notice the difference between a 30Hz display and a 60Hz display unless playing video games.
Try moving your mouse around. Try dragging a window around. Then try it on a 120Hz monitor. You will notice the significantly greater fluidity of motion added by each step up in refresh rate, even with bottom-of-the-line USB mice, which report at 125Hz.
Movies are 24hz and tv shows are 30hz (25hz in the UK).
Sports, news, and daytime dramas (yarg) are typically 50Hz or 60Hz, so they will be less fluid on a 30Hz display. Also, watching a 24Hz movie on a 30Hz monitor will make for a terribly juddery experience. The video will appear to "chunk" every 4 input frames/5 output frames, or 6 times per second.
----
All that said, for static design work, coding, writing, etc., 4K at 30Hz would still be very useful if you can put up with the less natural feel to basic system movements.
Indeed; I've seen a TV that couldn't even handle 1080p at 60Hz. Its video processor wasn't fast enough to handle some kinds of video, so the image would stutter and freeze during high motion scenes. It also had a terrible panel driving algorithm that was incredibly blurry unless its crappy 120Hz feature was enabled.
The video review does not have favourable things to say about it (flickering issues, lighting issues, etc.). I wonder though if the 39' Seiki 4K TV (going for $699) contains any sort of upgrade improving on the issues found in the 50' Seiki TV: http://www.amazon.com/Seiki-Digital-SE39UY04-39-Inch-Ultra/d...
> You will notice the significantly greater fluidity
Its the law of diminishing returns. When I had 30Hz and 60Hz monitor on the same desktop (as in I could drag windows from one monitor to the other) it was barely noticeable and not at all distracting.
> Sports, news, and daytime dramas (yarg) are typically 50Hz or 60Hz
That's interlaced. So 60 fields per second but only 30 frames per second. You can make an argument that proper de-interlacing requires a 60hz display but in practice its only the kind of thing that videophiles will notice.
> watching a 24Hz movie on a 30Hz monitor will make for a terribly juddery experience.
The seiki also accepts 24hz at 4K, and will even go as high as 120Hz if you feed it the right 1080p signal (the upscaling will look like crap though). You just need to fiddle the PC's display settings as needed.
Its the law of diminishing returns. When I had 30Hz and 60Hz monitor on the same desktop (as in I could drag windows from one monitor to the other) it was barely noticeable and not at all distracting.
Maybe different people are more or less sensitive, but after seeing a friend's 120Hz monitor, once I can afford to upgrade my primary display to a nice 120Hz screen I'll never go back. I have a very low tolerance for latency and jitter.
That's interlaced. So 60 fields per second but only 30 frames per second. You can make an argument that proper de-interlacing requires a 60hz display but in practice its only the kind of thing that videophiles will notice.
Not necessarily; AFAIK some stations might still broadcast in 720p60. I think most people will notice that the athletes seem to be "moving slower" if 60i is deinterlaced to 30p, they just won't have the vocabulary to describe it.
> Ironic for me that just as these things start to show up, I start to become less able to use them.
Same with me! I just bought the expensive 15" MacBook Pro with retina display, but I ended up using a 17" 1280x1024 external monitor with it to lower the eye strain. I am even more comfortable using a 19" 1280x1024 Dell monitor at work!
I am myopic with a spherical power of around -4 on both eyes. I used to love high-dpi displays until recently. But now I can't seem to look at them for long. I am sorry, but I can't figure out the exact reasons. I have tried changing the resolution on the retina display and even turning off the over-sampling in the lower resolutions, but nothing feels comfortable. I also loved programming with font anti-aliasing/smoothing turned off, but this alas no longer works well on the retina display.
>However you won't notice the difference between a 30Hz display and a 60Hz display unless playing video games.
This is absolute rubbish. I have an HTPC, and I played with the refresh rate settings on the TV. You can definitely notice the difference between 30Hz and 60Hz. Heck, I could even notice the difference between 50Hz and 60Hz (mouse movement was faster/more fluid).
I have the Seiki 50" and can confirm it is awesome for videogames. Using an Nvidia GTX 780 to drive the 4k resolution with "ultra" settings, and while the frame rate is 24-30 fps, you don't want to go back to 1080p.
Incidentally, sitting about 18 inches away from the monitor and you feel like you're in the game.
People bash Mac users for paying hundreds of dollars extra for style and marketing. But some of the extra cost does go somewhere: the display. I haven't been able to find anything approaching the pixel density of my 13" Macbook Air for less than $400. Name brands are more like $1000.
The 13-inch Macbook Air has a native resolution of 1440x900, which is a fairly low pixel density for a laptop and only slightly better than typical desktop monitors. Any modern[1] laptop should exceed the MBA's pixel density, and high-end laptops (Macbook Pro, Chromebook Pixel) nearly double it.
For any given pixel density a 32-inch panel will be much more expensive than a 13-inch panel, so it doesn't make much sense to compare a laptop screen to a desktop. A better Apple product to compare with is the Cinema Display, which has a 2560x1440 resolution at 27 inches and is priced the same as any other equivalently specced monitor.
[1] The 13-inch MBA has not had a screen refresh in years.
The modern trend in lower-cost laptops is unfortunately to use a 1366x768 screen resolution. Ultrabooks feature higher-resolution displays, but until recently the closest competitor to the MBA (Samsung Series 9) used the same resolution display (900 vertical pixels, though Apple uses a 16:10 aspect ratio while Samsung uses a 16:9). The most recent run of Ultrabooks does exceed the MBA's resolution, though, featuring 1080p displays (XPS 12, Vaio Pro 13, etc). But these are more expensive than the MBA.
Is there a consumer Windows laptop available at Best Buy or similar that has:
1) a solid state drive and
2) a display with Apple-level pixel density
for substantially less than a Mac? Closest I've gotten is configuring the ThinkPad T430 online up to $930, in which case we're not talking about that much cost savings.
I agree with you that any modern laptop should exceed its pixel density. But take a look at your local Best Buy. Even the 15" displays are usually 1366x768. Some of the most expensive Ultrabooks might be 1080p, but those prices are Apple-level anyway.
I'm between HS and college right now, so people are asking me for laptop recommendations. Most of them oppose Macs because they believe they'd be paying extra just for prestige, and I have a hard time finding them similar quality Windows hardware for any cheaper. Which leads me to conclude that Mac users are not just paying for prestige.
> Is there a consumer Windows laptop available at Best Buy or similar
You will not find good deals at Best Buy, on any product. Their business is selling low-value junk at hugely inflated prices, to customers who are unwilling or unable to purchase via the Internet.
> Most of them oppose Macs because they believe they'd
> be paying extra just for prestige
This may have been true ten years ago, but Apple's relentless optimization of their supply and manufacturing pipelines mean that their hardware is often less expensive than spec-equivalent competitors[1]. If you want a laptop as good as a Macbook, you'll be paying a price similar to a Macbook.
If you want a laptop with a decent screen and solid-state disk, there's a hard price floor imposed by the component manufacturing costs. Your best option if price is a strong constraint is to keep an eye on the manufacturers' sites for refurbished devices. See http://store.apple.com/us/browse/home/specialdeals/mac or http://outlet.lenovo.com/ as examples.
[1] Excluding accessories such as RAM, which are often marked up by 200-300% compared to high-quality third party products.
I understand all of this, but the people who ask me for laptop recommendations don't want to hear it.
Refurbs are a good point that I had forgotten about. Often, though, only higher-end machines are available (for the same price as a new low-end machine) and the base-level models don't come down in price much.
No it's a good TN display. The contrast ratio and overall quality of the MBA TN display is miles ahead of most cheap TN displays - many of which are a pitiful 200:1. You can easily tell the difference between it and a cheap e.g. Acer laptop. http://images.anandtech.com/graphs/graph6063/48121.png
Monitor manufacturer's REALLY need to start uniformly implementing some sort of remote control, for input source at least. KVMs are pretty expensive, these monitors generally have several inputs for multiple PCs (or other sources). Why not just have a USB-based protocol for switching the active source? or infra-red?

How is HighDPI support in Linux these days?
