  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

$1299 Seiki UHDTV 50" SE50UY04 - Bought it today

Mine is coming tomorrow. Woot. I am really worried about it not working on nvidia/linux though =(. HDMI direct or even DP -> HDMI adapters on hardware I know that is hdmi 1.4 compatable all say single TMDS (165 Mhz) pixel clock limit. I have a bad feeling the linux nvidia drivers do not support HDMI 1.4.

That's currently the case on my MacBook Pro under Mountain Lion, so it's limited to 17 Hz. However, I can get 30 Hz under Windows 7 in Boot Camp.

Which is just another reason that makes me thinkg linux is going to have issues. Luckily on the linux drivers you can force it to output the signal anyway but if it needs to do some sort of signal change for the higher bandwidth rates then that could be problematic. I do know the signal changes on DVI going from single link DVI -> Dual link DVI but I am not sure if that is the case for HDMI -> Dual link HDMI.
 
These specifically say they support 1920x1080 @ 120Hz which should be approximately the same amount of bandwidth for 3840x2160@30Hz so I am hoping they work for driving via display port.
I'm pretty sure it won't work, unfortunately.
 
There is a 4k Blu-ray task force.

It should be possible to make your own 4k, even 6k, 8k bluray, with the high density bluray data disk formats. If you can tap into use the encryption protection mechanism., you have a sellable format. As a player, any sub $300 PC that can handle 4k. The codec is where it gets tricky, to be covered by existing h265 licensing, or use an alternative like has been made for mpeg2 and h264 on web standards. The existing computer and authoring software should have some license, but if it covers this is another thing. Just something to think about.
 
My report

My report

Mine arrived yesterday. Here's a quick summary report:


  1. It's a 4K panel, no question or debate about it. The amount of detail vs. my 30" LCD (HP) is jaw-dropping. It's worth a purchase for this fact alone
  2. 4K Uprez with Samsung Blu-ray drive with 4K uprez works automatically
  3. 4K in Windows 7 works with GTX 660 card - did not work with GTX 460 likely due to driver issue with older Pureview support
  4. Picture adjustments - brightness, contrast, color, color temp, noise reduction work in all modes
  5. my panel has back light edge leakage and uneveness in uniformity as you might expect with a low cost panel. noticably when panel is not getting signal and showing black. but don't notice when displaying motion video
  6. quick auto calibration with Sypder 3 and v4 software got colors suprisinly accurate but appeared to crush blacks. will do manual calibration tonight
  7. the reason it's so cheap, IMO - for crap speakers, very basic menu, no extra features of any kind, panel is the quality of low mid-range LCD TV. But the 4K feature is a trump card. If it broke, tomorrow, I would get another one as soon as possible as for my IMAX project, seeing footage in 4K is a must

I've seen my footage on 80' screen with Barco's current top end 4K DLP - this monitor appeared to have the same resolution and detail resolving. That's a huge deal for me. Obviously color, contrast are not that same but no as bad I thought they might be.

Bottom line - very glad I have one. My non-technical wife was blown away whereas 3D was turnoff. I will see what others think, but I suspect 4K is going to be much bigger, much faster than 3D. Which means theatrical is going to have to consider 8K or even higher to separate.

Thanks Stephen - very useful report.

One quick question ... are there any Gamma settings? ... if not, when you were calibrating with your Spyder, what were you calibrating it to? ... Rec. 709 or sRGB?

Mine arrived today, haven't had a chance to unpack it yet but agree with on where the value is .... it's all in the 4K panel ... not in useless audio and networking BS features.

Cheers,
Neil
 
You hit the nail on the head, that non technical people can clearly see the difference on this UHD display.
I find it funny that many of the people that poo poo UHD displays have never actually seen one, and are regurgitating viewing distance write-ups by other people who have never seen one in person!

For a Red user : ' I was blind and now I can see ' .

No real gamma settings - I used the "warm" setting and calibrated to 2.2 6500k sRGB (which is what my other monitors are calibrated to). I was doing it in a rush - tonight I will have more time to play with calibration as well as longer displayport cable will be here.

Interesting ... I wonder where the crushed blacks were coming from? .... will set up my panel today ... let's compare notes tomorrow.

OMG... THIS THIS THIS!

I get so infuriated when I see people bring up that stupid chart that everybody seems to act like its the bible on HDTV resolution. I laugh when it says you n eed to be 2.5 feet away to see 4k @ 50 inches. What a joke. I can read super small fonts on my 22 inch 4k display from 2.5 feet away so that means I could do the same from atleast 10 feet away on a 50 inch display. I get very annoyed by that. All these people who spout crap who have never actually used or seen a 4k display. The 1080p viewing distances are BS too though..
 
Mine is on a freight truck somewhere...

Friends of mine in Phoenix have theirs. Seems their report echoes what Stephen says. When it all boils down to it, it's a crap LED TV like one would buy at WalMart, Costco, Sam's, etc.. But it does UHD/4K resolution for only about $350 more than what a crap 50" 1080p costs right now. So on that it's a WIN! As long as I don't set it right next to the new 55" 4K Sony, I think it will look just fine. ;)

Anyone buying one of these for color-critical viewing or correction work is making a huge mistake. From the few snippets I'm picking up online as well as my friends' report, best calibration practice seems to be just eyeballing it with a WOW disc or similar reference. Make it look good for your space, but if you're trying to match REC709 or specific gamma targets, you're just jerking off. I doubt my opinion on that will change after receiving it.

That's exactly on tonights menu - eyeball with wow disk and blue filter.
