Seiki SE50UY04 50" 4K display - Page 3

post #61 of 160
I've attempted calibration and I feel that I've achieved good levels. I'm really quite surprised that on all forums, no one shares the numbers on their calibration results. I'm going to remedy that here:
Color Mode: Cool
Gain Red 129
Gain Green 126
Gain Blue 131
Offset Red 503
Offset Green 510
Offset Blue 510
Backlight 100
Contrast 68
Brightness 59
Sharpness 0
Color 64
DCC Off

I hope this helps someone. If anyone else has calibrated professionally and cares to post, I'd appreciate it. Incidentally, I'm keeping tabs on a thread in HardForum that is addressing the issue of the occasional HDMI sync loss, which my TV suffers from (usually once every hour or two). Apparently Seiki released a firmware update on the May 10th that fixed sync, but broke audio. For those of us using it as a monitor, sync is far more important. At any rate, the firmware update (accessible through the service menu-- Menu key, then 0000) is no longer on Seiki's site, so I guess they're trying to fix the audio problem. More on that if I can find out anymore news.

will this work

video says ' 3840x2160 @ 60Hz (instead of the default 30Hz) for gaming.

No. The Sharp is utilizing a DisplayPort 1.2 connection which has much higher available bandwidth than the Seiki, which is using HDMI 1.4a. 31hz is all you'll be getting. If anyone can get faster than this, please share how you did it for the rest of us smile.gif
post #64 of 160
Some people on HardForum has theorized, that since the SEIKI 4K LCD can refresh all pixels at 120Hz (at least for scaled 1920x1080), it should be theoretically possible to create a HDMI 2.0 or DisplayPort 1.4 motherboard for the TV without replacing the panel which is apparently able to handle the bandwidth due it accepting scaled 4K data at 120Hz (from a 1080p source). Or even allow two cables to drive the TV as two side-by-side images (like the Sharp 4K can do).

But whether it's worth it, is up to question. The fact is we've got an outlier of an inexpensive 4K television, and it might be two years before 4K60 becomes cheap. So there's a window of opportunity for a third-party run of 100 motherboards, etc. There is actual precedent. People at 120hz.net and Overloard, got a run of custom 120Hz PCB's ordered for 1440p monitors. Example: Order Page for 120Hz circuit boards. A similiar thing could be theoretically done for the SEIKI.

True. That would be excellent, if it happens. I can confirm that it's still a very good buy. Been using it for two weeks now as a monitor--no regrets. Plays anything but FPS games very well. Skyrim is a dream on it.

If today's headline article is anything to judge, Samsung might be taking a page out of Overlords playbook.

Way too early to speculate, but there may be exciting times ahead.

I just created an 'official' thread for this tv in the LCD forum and linked to this thread:

http://www.avsforum.com/t/1473728/official-seiki-se50uy04-50-inch-4k-uhd-owners-thread

Having some issues and need to calibrate etc. etc. so I started collating that information on that thread. Welcome any comments etc.

so has anyone hooked a current-gen console to this yet? the price is great for this TV.

so you set up the PS4 or Xbox One to 1080p/60Hz and then let the TV upscale it to the TV's native resolution of 4K (with the 30 Hz limit)? if the resolution of the TV is not native 1080p, then won't that make the image worse than a native 1080p panel would show it at (especially since I have no clue the quality of Seiki's scaling)?

It divides evenly, so it should look pretty good.

yeah, but would like to hear someone with first-hand experience. my friend had an old laptop with a resolution that divided evenly from the default panel resolution and it still looked blurry at the non-native resolution.
post #71 of 160
The "scaler" in the Seiki is a simple pixel doubler, so 1080p content (like that from an Xbox 360 or PS3) looks a little fuzzy up-close. Having said that, it accepts up to 110 Hz input @ 1080p over a single HDMI if your gaming device can do it, and pixel-doubles it up to 4K at that frame rate. The 30Hz @ 4K limitation is caused by the HDMI 1.4 standard, not the display. If there was an input on the display that could handle 60 or 120 Hz 4K input, the panel is capable of displaying it.

It's only really dividing equally if its a 4:1, 9:1 or 16:1 ratio though...anything else will break the squareness of pixels.

It depends on how they do it. If they're using bilinear or any traditional upscaler, pixels won't be clearly defined. If there's an option for nearest neighbor scaling though, then it should look exactly like it does on 1080p - just 4 pixels of the exact same color for every 1 pixel in the 1080p image. Its a very rare display that lets you choose this though.

I think from a reasonable seating distance, with 1080p content, you'd have a difficult time telling the native 1080p panel from the scaled 4K one though.

39" 4k display $699

Sorely tempted to pick one up, but I'll probably wait to see what Asus puts out with the same 39" panel. Someone (other than Asus) needs to put a displayport in one of these cheapie 4k displays to get the refresh rate up to a usable 60Hz. If the Asus panel costs $999 I'll probably pick it up, if it's like $1500+ I'll probably just go for the Seiki.

I think the part you missed is that ASUS announced their 31.5" 4K @ $3799 so the 39" in Q3 isn't really going to be cheap.

I thought that at first too, but since it uses the same cheaper 39" panel as the Seiko and Chinese models, it should come in at ~ $1000.

Hooked it up to a SONY F55, quad HDSDI out to a AJA Hi5-4k to get HDMI 1.4 and the monitor displayed 3840 x 2160@24hz.

Our part numbers on these monitors are as follows:

SEI-SE39UY04 90
SEI-SE50UY04-90

AJA:

We have a color grader coming in sometime soon to take a look at the monitor.

...Auto correct on the iPhone changes "Seiki" to "Swill"...

You can get the 50" off Amazon for $966 or used through Amazon Wholesalers for $860. Tempted but I think I'll wait for the cheaper Asus with displayport.

But realistically, what good are these things without the updated HDMI or dual DVI or something ? Who cares how cheap they get ?

Without at least 60Hz they're not much good for FPS/Twitch gaming. I guess they'll be good for stuff like WoW and Starcraft @4k (or you can run it at 120Hz @ 1080p), that's about it.

I'd rather just wait for the cheaper 4k displayport 1.2 monitors to come out.

Ditto that. Plus 39" is still too large for me I believe. I haven't played with the idea of a monitor farther away though.

OK, about 8 weeks ago, when the price was $1500, Gizmodo wrote: "How the Hell Is a TV This Beautiful So Cheap". http://gizmodo.com/5994765/seiki-50+inch-4k-tv-eyes+on-how-the-hell-is-a-tv-this-beautiful-so-cheap

Well, I pulled the trigger on it this morning. The Amazon price was just too good to pass up. $965 with Prime shipping. It'll be here in 1 week.

http://www.amazon.com/gp/product/B00BXF7I9M/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

The last time I early adopted a TV, I bought a 42" plasma for 5K for my den (10+ years ago), which I'm now replacing with this TV. So, I guess I'm thinking I've learned, and those early plasmas were power suckers. My fuzzy math justification is it'll pay for itself with electricity savings. wink.gif

Can't wait to give it a whirl. At this price, at least I won't feel bad a few years from now, like I did when I bought that plasma.

Addendum - I've been watching this for about a month and it looks like they've had this deal before, so not quite breaking news.

I backordered the 39" from BuyDig and received it last week. It replaced two 20" LCDs for me. I had considered the Dell 30", but the Seiki is considerably less cost and twice the resolution.

I'm completely pleased with it. For FPS at 4k, if VSYNC is on, it's not usable. The lag is way to high.
At 1080p/60Hz or at 4k with Vsync Off, it's very usable.

No dead or stuck pixels on mine. I've been incredibly thrilled with it. Only bad thing is that it's a TV not a monitor. It doesn't go into sleep nor wakeup by itself.

Runs great from my Radeon 6870/1G with Radeon 13.1 drivers. When I switched to 13.4 drivers, 4k resolution disappeared and the computer switched to 1080p. Not sure what it was, but I'm back to 13.1 and 4k res.

Games run fine at 4k res, but I do have AA turned off. Don't really need it at 4k.

I'm not sure how to calculate memory requirements, but 32-bit @ 8MP = ~32MB. That's a minimum for VRAM. At 8x AA, that might be more like 128MB I think. I've read a lot of posts about how 2GB isn't enough for 4k, but most of the FPS games that I've tried run perfectly fine on 1GB. I will eventually replace the video card, but right now, I don't feel a need.

Very interesting. I currently have a 27in Yamakasi 2k monitor,wonderfull monitor. At 120hz it would be spectacular . I have a few 120hz TN monitors but prefer the 2k ips monitor, so much more detail and superior color. The idea of running it at 120hz gets me pretty excited. But the idea of 4k doing 60 plus hz is just so freaking cool.biggrin.gif

Will today's Mac Mini's output 4k?

The Intel HD 4000 graphics of the current Mac Mini supports 4K resolutions, but not over HDMI. You will have to use a DisplayPort to HDMI adapter that supports HDMI 1.4a and 4K resolution. The newer Intel HD 4600 and 5200 graphics in the 4th generation core processors (coming in the next Mac mini) do support 4K resolution over a single HDMI 1.4 cable. Also, you will need OS X 10.9 Mavericks as that is the first version that natively supports 4K resolutions. Mountain Lion and earlier have a software limitation that prevent Macs from outputting 4K over a single HDMI/DisplayPort even if their hardware is capable of it.

Hey. I wanted to commend Mark for his work in this area. Mark really stepped up to the plate and has done some great work to continue to look at refresh rate and motion portrayal issues.

I also recently purchased one of these displays, and this is truly an exciting time for the display industry. I'm sure that the other manufacturers will finally see that people are having demand for this type of technology once there are more sets than can do more than just 1080p60 and that's pretty much it for the rest of the industry.

The entire display industry has selfishly preoccupied itself with film for far too long and neglected the needs for hard core gamers.

Anyway, my hat is off to Mark. WHAT A GREAT JOB THIS GUY IS DOING!!!
