Unboxing and overview of the Seiki 39" model: http://www.pcper.com/news/General-Tech/Video-Perspective-SEIKI-SE39UY04-39-4K-3840x2160-TV-Unboxing-and-Overview

Seeing it set up on their test bench with the presenter sitting in front of it, it seems like the ideal size for a desktop monitor.

I'm jealous of that setup, but not because of the screen.  I can't stand the fact that his surface area is devoid of clutter.  That's a skill I've never mastered, never will master, and am doomed to struggle with forever.

A lot of it is due to building good habits, and setting things up to make it easier to keep tidy.

If you get a keyboard & mouse platform, that immediately removes a huge amount of clutter from your workspace, especially if you have wired devices. I use a Humanscale platform which is very adjustable, and has really helped reduce the shoulder and wrist pain I used to get. (this is why there are two mice)
Mount anything you can to the underside of the desk, if it doesn't need to be sitting on top. Run all your USB devices through a hub to minimize cable clutter. Zip ties and zip tie mounts are a great help here. Buy a pack of 100 and go nuts - they're cheap.
Get rid of your paperwork ASAP. That box on the corner of the the desk is a Fujitsu scanner - it's USB powered and the software integration is great. It takes maybe 10 seconds to scan a page and create an OCR'ed PDF. Unless I really need to keep a paper copy for my records, anything that comes in is scanned and immediately shredded. Anything that needs to be retained is immediately filed. Depending on the volume of paperwork you have coming in, you may need one of the higher-end models, but I like that this one has such a small footprint and doesn't require a power brick.
And make sure everything has a place it's supposed to be, rather than just moving things around when you happen to need them. All the filed paperwork, stationery, printer etc. is in a cabinet just to the right of the desk so that it's out of sight, but easily accessible. Unless it's needed on a daily basis, it does not belong on the desk if it's not currently in use.


Anyway, sorry for helping take things further off-topic. But at least you can see why I want a 4K or even 8K display to connect up to my PC.
4K gets you either twice the workspace, or twice the resolution.
8K gets you twice the workspace and twice the resolution. (or four times the resolution or workspace)

I couldn't go back to using a standard size PC monitor on a daily basis now.

How do you name the paperwork so that it is sensible?  I would love to drop paperwork into a magic box that sorts and names things in a structure where I can find them.  Or do you rely on searching through the PDF's?  I looked through that link...it looks good, but I don't see an auto-naming ability.

Yes, but my own rigs won't support 4K- they don't support 4 screens.

I'm still unsure about something.  Is 4K going to require substantially worse color subsampling or not?

Hey guys,

I'm looking for feedback from someone who owns this on 2 points.

a) 1440p resolution, has anyone sucessfully been able to custom resolution it @ 60hz (or more). I've read some people could do it at 60hz and even in the 80hz range.

b) between the 1080p (scaled by Video card, as to not get the overscan issue) and 1440p (which is scaled), which resolution delivers a better image for gaming? With the scaling @ 1440p vs the "native" 1080p (4 pixels = 1 pixel), are you seeing a more detailed image @ 1440p or 1080p?

Thanks,

I think they are still using 4:2:0 which means that the chroma image will still have 1/4 the resolution of the source. (1920x1080 chroma with a 4K signal)

This means that 4K sources should look a lot better scaled down to 1080p displays as well, as chroma will be displayed 1:1, and compression artifacts in the luma image will be minimized due to the downscaling.

Crux of the problem is that modern compression is a toolbox which offers range of bitrate vs. PQ tradeoffs, e.g. for H.264 25 Mb/s, 10 Mb/s and even 6 Mb/s might be 'good' or 'excellent' in PR materials. There are however evident differences between them for critical viewers.
Now, the 4K makes sense if the target is highest PQ. So, if you one claims that 4K H.265 will be better than 1080 BR H.264 @25 Mb/s then why not compare65pFOd
it with the 1080 compressed @H.265? What one would have then would be quite squeezed 4K and 1080 with healthy overhead in its bit budget.Squeezed 4K effect would be close to downconverting it to 1080 plus some other potential side effects. Thus, one needs healthy increase in the 4K compression bitrate over 1080 to show its strength. A factor of 2 sounds like minimum.

It's still unclear how far 265 will bring pull the data requirement downward.  I'm not familiar with it, nor have I heard anyone in the industry talk about how they're going to be encoding 4K.

 

From the point of view of FIOS/Comcast/Dish/DirecTV/etc., I have to wonder if what we'll end up seeing is a "weeding out" of channel offerings to make room.  No more Acme Bland Vanilla Channel, etc.

So basically this is the same 110" 4K built by China Star CSOT that countless others like TCL and Hisense have trotted out when they need publicity for a set they will never build. At least the price came down from last years $300K.

You need to replace all your set-top boxes to go to H.265. Given that everyone has just gone through a transition to H.264, don't look forward to too much excitement around this anytime soon.

Instead, I expect we'll see a special box for 4K customers that decodes the H.265 in the interim. It's probably several years before mainstream concern around this issue materializes.

There is no difference in HDMI cables. If you can see the picture without visible dropouts or sparklies, the cable is working at 100%. No other cable will display a better version of that picture. You're simply wrong if you think there is a better digital cable than one that is already working.
