Nope. But I should put some time in for that. Just haven't bothered to date.

Were one to build an HTPC for a 4K TV, what sort of requirements are you looking at?
What is the lowest-powered fanless video card that could do the job?
CPU?
I'm assuming hardware decoding would be a must, what would you guys look for with regards to software?
Uncompressed 4k video is just under 500MB/s, should supporting that locally be a consideration? Assuming 100MB/s GbE is fine for the rest?

7x00 ATI GPUs have hardware support for decoding and displaying 4k video, which means the other, wrong-er people probably can with current GPUs as well.
For the rest I'd probably look at a low power i3 and run XBMC.

I didn't think S3 Graphics made modern graphics cards any more?

I've actually been strongly tempted to get an Intel NUC system except that HD4000 graphics have some pretty serious compromises if you want a full AV experience.
Given that nVidia makes high performance ARM SoCs and GPUs, in another generation or so I suspect that we'll have an Android-based system that can very credibly do HTPC stuff, including the 4K video output.

They still do, but aimed at embedded markets. You can still purchased stand-alone cards, but are very difficult to find.
IIRC, their latest chipset has full hardware acceleration for H.264, MPEG-4, VC-1, WMV-HD and AVS, OpenGL 3.0 and DX10.1 support, all in roughly a 2-10W power envelope.

Finally got the display to work at full res (3840x2160). I've concluded that there is no way to use the mini DisplayPort to do anything better than 1080P. I bought countless adapters and cables at various price points and all behaved exactly the same. Finally got a DVI->HDMI cable and it worked right away. Man is that pretty.

Highest resolution DisplayPort adapter I've seen is 2560x1600 (like these at Newegg).
Then you need to remember to use a dual link DVI cable as well... I've had 'clients' [family] omit that bit -despite written instructions- and call me at midnight to yell at me 'cause their brand new 27" lcd was blurry.

This is just temporary of course, learning what it can do. But it was fun to have Adobe Bridge on the huge left and Photoshop on the calibrated 30"er on the right.

Finally got the x-rite i1 out to try and calibrate it....better, but horrible. The pixels aren't exceptionally sharp or well-defined either. Great for video, but not as a monitor.
Still, Civ5 is great at this resolution

Aw. The lack of sharpness is disappointing but not surprising given the cost. Do you think the lack of sharpness is due to some sort of AR coating or did they go pentile or some other non-RGB stripe?
ddrueding

It just looks blurry. When I bring my macro home I'll take a few pictures.
Granted, it is sharper than any of my 1080P screens, but the color is still way off.

It looks like the RGB stripe is reversed from how Windows is expecting it to be. That may cause the subpixel rendering to be incorrect.

That is very possible. Can Windows be told to deal with it? I know the font smoothing (ClearType?) supports different modes.

I would think you would want to turn off ClearType.

I'd try the built-in ClearType adjustments in Fonts (Win7) or the tools (WinXP, Vista) first.

That's both good and bad.
Good news-they're making something which is actually designed as a 4K monitor, not a 4K TV, and thus acknowledging the need for such a thing.
Bad news-the price, obviously, and for me the fact that it's not 21" to 24".
Now if someone makes a monitor using the 230 ppi panel in this tablet...
It looks like that crappy 16:9 ratio. :tdown:

Not saying you're wrong, but you might as well get used to it. We won't be seeing special resolutions for monitors that aren't used in TVs much in the future.

Anyone know of an onboard graphics solution that can handle 4k? I'm looking into building a small computer to drive a 4k display. Ideally it would be a single-board solution using an mSATA SSD and a PicoPSU that I could just mount to the back of the TV.
Intel is decidedly not helpful in this respect:
I'm even less familiar with the AMD options, and their website isn't giving me anything.
Thoughts?

IIRC, Haswell has 4K support... (IvyBridge had 4K support, but not on HDMI)

Great find, thanks. I was just reading through the Iris Pro 5200 review on their site looking for just that:

An important caveat in that review:
Dependent on cable length? I can use a 1' cable in my case.....worth a try?

My setup (A10-5800K and F2A85V-PRO) supports up to 4096x2160@60Hz through DisplayPort. DVI is limited to 2560x1600@60Hz, and HDMI is limited to standard 1920x1080@60Hz

I think I'll be going this way:
Gigabyte GA-Z87N-WIFI (2 x HDMI ports, supporting a maximum resolution of 4096x2160
* Support for HDMI 1.4a version.)
Intel i7-4770S (HD 4600 graphics)
Gigabyte seems to have dropped mSATA on the Z87 boards.

Don't forget, you may or may not need to change power supplies. I have no idea if the Pico PSU supports Haswell's chipset. Power supplies designed for earlier chipset's may not power up when signaled to do so by a Haswell MB.
I'm not saying it won't work, but I think you need to be prepared for the possibility that it won't work until Pico updates its PS's to work. Their are few equivalent alternatives to Pico PSU's. You may wish to contact Pico to find out before committing money.

I had no idea Haswell was changing the ATX12v PSU spec. And I still can't find a link to good information. Thanks for the warning.

My (admittedly unfocused) monitoring of the PSU issue left me with the impression is that the potential problem was PSUs not being able to cope with Haswell's extremely low power draw in its C7 state.
From this VR-Zone article:
Edit: Anandtech also says it is not an issue with the currently available SKUs:
From this VR-Zone article:
If P5 knows of another issue, I'd appreciate a link.According to our sources, the new C6/C7 power states on the Haswell-Shark Bay platform will require the system power supply to be able to maintain a minimum current load of 0.05Amps on the CPU exclusive 12V2 rail (0.6W).Older or bargain basement power supply units may be unable to achieve this, and might become unstable or trigger a UVP/OVP shutdown once the system enters the C6/C7 power states. This is because the previous ATX12V v2.3 design guidelines for Ivy Bridge and its predecessors only called for a minimum load of 0.5 Amps on the CPU power rail, hence a less sophisticated internal feedback loop/protection could be used in older or cost-reduced offerings, which will not support the new standards.
