  • 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

Hmm.. With the sharpness turned to 0 I don't see any processing really @ 4k (fonts are pixel to pixel and look great). Also once I got a proper videocard with working drivers I never get dropouts anymore as long as I stick to HDMI1/HDMI2 even over a 60+ foot redmere HDMI cable.

I of course am not using devices to hook up with it (which I am sure some have problems) and just using a computer and all I will ever hook up to it so for my workload it works well.

From a computer usually works pretty well, but I've got one system here that needs the signal stabilized to avoid dropouts. The HDMI3 port on the SEIKI is F'd up on every SEIKI I've played with. While it's not very many, I can say they definitely have an issue there as it's been that way on all 4 I've had a chance to test it on. I think it's an EMI issue. The display struggles with most 4K sources I've connected and all of the SEIKI's I've seen show the "judder" effect with 4K 24Hz. I don't get what's up, but there is no judder in the footage, it has something to do with the internal buffering or processing of the display. As if it can't keep a regular cadence on its output. Most everyone else tells me they don't see it, but I always do. I'm not the only one who sees it, but I guess myself and the one or two others that concur with me are more sensitive to it.

I don't get why the display is so finicky about HDMI signals at 4K and why running through a unit that boosts the signal or freezes the EDID info seems to fix it.

Honestly 30Hz IMHO is fine for just desktop use and video. The only time I really need the 60Hz+ is for gaming and in that case I just drop down the resolution. Honestly even if it did 60Hz @ 3840x2160 I might still drop down to 1920x1080 to get 120Hz like I get now.

To each their own. 30Hz blows when you're doing CAD work or scrolling full pages of code. Have always had a love/ hate relationship with LCD displays running at 60Hz. Only recently have we been able to move beyond that. Still miss the fluid response of CRTs in the past when we were running 2048x1536 @ 85Hz for our CAD and 3D modeling stations. 30Hz is also worthless if we're trying to work with 50 or 60 Hz video. Not that I need 60Hz 4K, but if I want to throw a window up on it to show 1080p60, well, ooops. If I connect the thing as a secondary large desktop -- and I ran with it that way for a while -- it's too much of a compromise. Sure, the extra pixels are awesome, but everything else was a complete compromise.

I can't get pixel for pixel signal throughput on any SEIKI I've played with. Even with sharpening at 0. It's close, but it's not 100%. More like 95%. FWIW, I can't get it to happen on the Sony either.

Too bad Sony didn't stick with the removable speaker design on the 84". I like the "monolith" design cue, but if your cabinet/wall was just a couple inches too narrow how great would it be to be able to remove them?

Sony does this every few TV iterations, they have some designer that likes big dumbo-ear speakers. The 65" Sony 4K is 3/8" W-I-D-E-R than my 75" Samsung. LOL.

The 39" Seiki Just showed up. First one out of the box seems to have the screen flashing worse than I have seen it on the 50". Hopefully a firmware will some day fix that. Will try with the boosters.

Its an interesting size... good for a workstation when you are really close. Everything is pretty much the same as it's big brother.
 
I have the 50 Seiki and the 55" Sony in my office being driven at the same time with the Titan card.
I must say that the Seiki looks very very good next to the Sony. The Seiki also seems to allow brighter settings to overcome room lights if needed.
Sony has less view angle issues too, especially noticable when the screen is all black. The Sony stays blacker when you more your head up and down a bit.

Jeff : So i'm not the only one with judder problems, which I have been bitching about here for the longest time ! ;) Nobody seemed to care.
I know it's not my media because it plays smooth on the 30" Dell.
The Sony does play smoother than the Seiki as well.
 
I wonder what differences, if any, there are between the 39" and the 50" in terms of the electronics? Other than the dot pitch, and possibly the PSU, is there anything else fundamentally different between the two units? Does the newer 39" actually have different boards? Are the menus and such the same? Perhaps same hardware but different firmware?

I don't expect stunning PQ at the Seiki's price point, or even sophisticated electronics. That said, if it can't be trusted then its not nearly as useful as a monitor.

Perhaps more to the point, what is the state of the UHD ecosystem in July of 2013? Is there a proper standard for things like EDID and HDCP in UHD that all manufacturers can consider a reliable reference? If so, and IF Seiki is cutting corners, then they need to come correct. I wonder what source devices they test with? I wonder how uniform the signaling is from various devices/graphics boards?

Basically I don't want to throw Seiki under the bus unless they deserve it. Moreover, if we can determine what signal metrics the Seiki likes, then perhaps we can figure out "best settings" to make it happy.

The Seiki on OSX 10.9 DP3 Mavericks with GTX680 was working intermittently- sometimes the EDID would send, sometimes it would not send.... I am happy to report I have been testing it this week using the Accell DisplayPort 1.1 to HDMI 1.4 Active Adapter, and now it is working nonstop, albeit at 25hz, which is fine as a client preview monitor. People who come to my office are just blown away. I had a seasoned production friend I shoot with regularly come to my studio yesterday, he was in awe of the quality of his first time ever seeing 5K mastered to 4K on a 4K display. EDIT- Updated the firmware on the Seiki, and now it is working on 10.8.4 @30hz with no issues!
 
Got ours a week ago and have yet to see anything in 4k! (Waiting for RedRay)

Anyone care to tell me what is the best card for a Mac? Will it play 4k out to the Seiki from RCXPro?

Thanks!

Kevin

Ive been seeing the same thing with Mavericks.. and oddly enough one reboot it forced my mac into safe mode which I have never saw before.
 
From reading through posts, to get a 4k signal out via HDMI, it sounds like the most popular card is the Evga Titan GTX card, is that correct?

Jared, you mentioned you guys are using the GTX680, right?

Any other options that work?

I concur with this, but the backlight on the SEIKI is extremely biased toward blue and they have to crank the red channel to try and balance it out. It comes out of the box with some seriously funky red push going on. It does seem a bit brighter than the Sony, but I've had to dial it back and tweak the red levels to get skin tones into more normal hues instead of looking pink. All things considered, the SEIKI looks very good and holds up well next to the Sony once it's been dialed in. The Sony is the superior display in every aspect other than price. I suppose the SEIKI has an advantage if you typically have it in a bright room. But at higher brightness levels, the colors start to go funky.

The judder issue has me pretty pissed off. Probably more so than any of the other issues because it's the one serious flaw that they won't acknowledge.

Titan is working great here for me in Windows. For a Mac Pro, I would stick with the GTX680 if you need CUDA, otherwise the Radeon 7950. You can actually get the official Mac version of the 680 for within $20-$50 of the equivalent EVGA (or similar) common PC version of you look around. Then you don't have to dink around with hacked firmware or cards with no warranty and improper PCIe reporting in profiler so you have to guess whether or not it's working right. The Sapphire Radeon 7950 for Mac is a great card. It can drive up to three 4K displays at once, or so I'm told. Supports 4K on both of it's mini DP ports as well as it's HDMI 1.4 port.

That said, I have not really played with 4K output from the GPU on a Mac Pro. Both of my Mac Pro towers have hacked GTX570's in them still. :) I did try the Titan in a Mac Pro a couple months back, but driver support just wasn't there yet. I've heard it's better, but still incomplete with the latest drivers.

Just pre-ordered one (39") at amazon for $498 !
Click to expand...

I see this one is listed as being 120 Hz... When I checked the 50" there was no reference to the Hz, which IIRC was 30. Can someone explain to me how this will affect my using the 39 inch as a display monitor? Will I be able to view 48 TIMEBASE footage properly?
 
I also ordered the 39 inch one too. I couldn't pass up $498. To the guy that got the 39 inch already is it also limited to 31 Hz like the 50 inch one?
