Seiki SE50UY04 3840x2160 50" TV ($1300)

This

At 38hz the input lag is acceptable. If there was a brute force way to disable the scaler we'd have good looking 4k res w/ tolerable lag.

As has been mentioned many moons ago in this thread, to get native 4k resolution the input board feeds 120hz 1080p to do 4k 30hz (sending 4 1080p frames per frame.) I think this adds a lot of the input lag.

It also forces it to run at 30hz 4k, and it simply cannot without a lot more modwork work at higher resolutions (31hz even frame skips.)

I disabled via a firmware mod the 31hz scaler that turns on and put it at 38hz, it does not improve input lag and simply adds more frame skipping.
 
Yes. Your post from Feb 2014 (mipsel decompilation, etc) is what I'm attempting to expand on. I've been trying to recreate your mod that disabled the onboard scaler for 2160 @ 31.1+ and higher but not having the success you had. I have been able to get 1080p as high as 144hz (36*4, 148 is noisy and no luck with 152) with no frame skipping which tells me both the bandwidth is there and the hardware is capable of doing that amount of drawing.

I'm trying to apply the above to the newest 7-7-14 50" firmware. It has a few ms less lag (it's still not perfect, but it's noticeable) than the earlier 50" fw (and derivatives). A few ms less lag per frame draw, a few extra hz before the scaler kicks in, those things would make the display that much more practical.

Just attempting some experiments with a fresh set of eyes on a newer revision of software. Couldn't hurt anything.
 
pbassjunk: btw, you can squeeze out more bandwith/higher clocks if reducing padding & disabling hdmi audio.
 
I suspect he was referring to how much smoother 38hz is over 30hz, to see if it would even be worth attempting to fix the scaling issue.

My answer to that would be, when you are dealing with such low refresh rates, almost anything is a worthwhile improvement!

Considering that this TV skips frames at 31Hz, which is still "good image quality 4k" i fear any subjective input lag improvement reported is mostly delusional.:rolleyes:

I am not saying it is impossible, i am just saying that we should look elsewhere for answers, like taking a look at konka/skyworth firmware and comparing it to seiki's

Right, the question would be if you can get it into that mode and override it from its hard-preset 120hz 1080p that it sends for 4k 30hz without the source code (I browsed the disassembly for a while but couldn't get it to push past 120hz when in 4k mode, though it's not an easy task to find.) This might have to do with figuring out the branching point of the line of disassembly I tweaked and figuring out what all the non-scaler version is doing and where the variables are set, but it's all very hard without the source code.

Like I mentioned before, the 7-7-14 firmware is no different from the latest 50" firmware they had on their site. I think a lot of people notice less input lag because immediately after installing the firmware and boot up, the tv takes a while to warm up and the input lag is lower for maybe a minute or two before it warms up or something (maybe figuring out what increases the lag over time could help?) Though I could be deluded as well, as when I tried to measure said differences, I didn't find any.
 
So can anybody tell me if the Seiki U-VISION cable improves upon the quality of 1440p content on this TV?
Would be worth a purchase if it does!

Over GPU scaling? You are going to be limited to the same 30Hz as if you were doing GPU scaling so I don't see the point.
 
Any pointers on modifying the EDID settings in the firmware? Is it just a matter of replacing the correct parts of the dvdplayer file?

I ask because I'm trying to force 1080p at 30 hz. That's the opposite direction of all the custom firmware, but the U-Vision cable can only upscale 1080p/30 or 24, and I'm trying to get it to work on 1080p output from a console(PS3, but I think the Xbox 360 is the same) that does 1080p/60 by default and doesn't seem to have any way to force a lower refresh rate. Hopefully if the console detects the display as only supporting 1080p/30 it'll output at that lower frame rate. And doing that seems to require a custom EDID
 
I just switched over to nvidia, When I hook my 39" seiki up, the resolution/desktop itself looks fine, but when I open up windows or menus they're all in the 1080 sizing just scaled up. Not familiar with enough with nvidia control panel.

The screen is also, turning on and off, blanking? perhaps?

I just entered 3840x2160 in CRU, didn't change any other settings.

gpu is 970m SLI

**EDIT I'm partially a dumbass, menu size can be established by checking "Let me choose one scaling level for all my displays" in Display properties after selecting "Make text and other items larger or smaller" within Screen Resolution.

Still not sure what to do about the blanking.

First, scan this thread for the appropriate manual timing settings. Setting it to automatic for me resulted in blanking, but the manual settings fixed it. This can also be caused by having a shitty HDMI cable, but try the settings first.
 
Merry Xmas everybody. As a person who did alot of research on this and other forums before buying a Seiki around Halloween, I've got some GREAT news that has eluded a lot of people. I'm standing on the backs of giants for this, but nevertheless, I put it all together and now can show people how it's done. What is it?

Getting 3D Vision working with the Seiki!!!!!!!

That's right, I got it working last night and tested it (and enjoyed) Star Trek Into Darkness 3D bluray.

There's limitations, but it WORKS!!!!!

First the how:

You need to use the .inf method and spoof your windows and 3dvision into thinking it's something else, specifically the Acer_H5360. It's a DLP 3D projector.

Which means you need to use the DVI to HDMI that came with the 3dvision.

So when you want to run 3D blu rays or 3d video games, you need to load that inf and restart your OS. Then when you want to switch back, just switch it back, or use windows to search for the Generic PNP device inf and go back. Note: This is just when you want to switch your resolution capability. If you are fine with 1080p/60 for surfing the net and stuff, you can keep it at this resolution for a while, i.e. you're not pressed to switch it back immediately since 1080p/60 is still decent to do other stuff temporarily.

Another limitation, is that I guess since you are using a projector .inf, there is no sound through the seiki speakers. BUT... if you have any sort of speakers connected to your PC motherboard/soundcard... then this works just fine. My soundbar works great. So you lose the ability to use the seiki's internal speakers.

Another limitation is that this is limited to 1280x720p. So no full hd at this time. I'm not familiar with DLP projectors, but I have a feeling once someone releases or finds/makes a 1080p 3D projector .inf, then maybe even this limitation will fall. Of course the .inf the projector is linked to has to be 3D Vision Ready by Nvidia.

Another limitation is that the eyes are swapped. So with games, you'll need to wear the glasses upside down. Some people have used an eye swapper, but I haven't gotten this to work. Some others have suggested removing the lenses and switching them, and it worked for them. I can't confirm it. Some have said that in some games you don't need to swap eyes as it gives you a setting. I haven't played any games yet, so I can't confirm that.

BUT....at least with PowerDVD10, which is what I have, you CAN tell it to swap the left eye for the right eye, and thus at least with this program you can swap the eyes and use the glasses normally.

Also at first I had it in a really small screen, but that was because I was using the dot-for-dot, as soon as I used the remote's 'aspect' button it stretched it out and everything was full screen.

I had been looking everywhere and remember seeing people say they got this all to work, but the information was vague so I had to piece it all together and find a copy of the .inf.

But it's done, it works, and now it's documented.

It's works pretty good too. A little bit of cross talk, but it still completely works. I love it.

So add another confirmed use for the GREAT Seiki 4ktv. Oh and I'm using the 39" with one of the 50" firmwares.

(oh and since I'm on here I'd also like to report I can get 1440p/80 simply using the custom resolution through nvidia control panel and CVT reduced blank, as well as 1080/136, 1800/52 and 1980/43)

I know how important this 3D vision is to people so I wanted to post it here. I've literally read hundreds of posts on dozens of websites of people asking about it.

Oh I don't know how long the link will last, it's pretty old I think, but it still worked for me.

Buddy..... YOU ARE SO FREAKING AWESOME!!!
I came here today expecting nothing and got some very cool news indeed! Thanks! smile.gif

Now to get 1080p working with 3D, and get that scaling figured out! Then..... THE WORLD!!!
MWAHAHAHAHAHA!


HAPPY HOLIDAYS EVERYBODY!

(Here too? A guy gets around)
 
i can confirm that version jul-2014 firmware on page 9 of this AVSforum topic.
http://www.avsforum.com/forum/166-l...-se50uy04-50-inch-4k-uhd-owners-thread-9.html
I had emailed Seiki and bugged them a while on Facebook for a new firmware seemingly to no avail. Today, completely out of the blue, I get this:

You can download a copy of firmware here: https://mega.co.nz/#!LFEGFQDY!Mk5B75NEYk3dEMBtJ72Q2xMKl8RJaWB3U6hwc87ojPs

Software upgrading instructions for SE50UY04:

1. Please "unzip" the download and put the "install.img" file under the root directory of a USB flash drive. And insert the flash drive into USB port in back of TV.
CAUTION: Do not remove the USB flash drive or power off TV during updating, otherwise the operation will fail.

2. Press "Menu" button on the Remote control first, then press number key “0” four times in a row to enter the hidden Factory Menu before Menu screen disappears.

3. Move cursor to "Software Upgrade" option and press OK key to start upgrading.

4. After about 10 seconds, it will be into the upgrade status, and the screen will display the upgrade progress interface.

5. Please keep power on during the upgrading process, it will take about 1~2 min.
After upgrading successfully, system will automatically power on.

Looks like a newer version even than the 1.1 my set shipped with. I have NOT yet attempted the update, though given this is from Seiki directly, I assume it is safe. That being said, proceed at your own risk until we have reports of what changes are included.



this unlocks the pixel clock past the so called 297Mhz Limit imposed on previous firmwares
I tried 4k @ 31hz works fine

32, 34, 35, 38, 39, 40, 45hz Work.. But scaler ruins the images

39-45hz works but sometimes blanks for 5 seconds sometimes, mouse is soooo smooth... I want scaler disable option...

to be expected @ 397pixel clock...

the image scaler kicks in anywhere past 31hz...

so i imagine we can run 1080p with 150hz.. needs some tweaking, as I get white blanking

Tweaked!
1000

Larger

also...
engineer menu, 2947
HDMI --> 3D Settings

found 3D settings and allows side by side./ top and bottom but they dont seem to work 100% so I imagine experimentation is required.. and alot of time!! haha

Awesome update! Wish I had a 3d vision kit to test. All I have are active shutterglasses for sony.

1440p/80hz is doable, but the scaling looks like ass.

Good looking out guys!
 
I have an odd feeling this screen is actually 4x 19.5" screens glued together (IE: I have the SE39UY04) .. or atleast they have wired it up that way.

Have you seen the nonsence that happens when you run 3840x2160 and start altering the overscan settings..
It is like the monitor is separated into 4 squares!!! and they all start piss-farting around with the image.

It seems we wont able to remove the scaler as this tv doesnt seem to be a true 4k panel?! I am totally confused with the mess Seiki did to make this TV.

The only thing which gives me hope, is when in my Computer's BIOS, it's a resolution of about 720x480 or something small, Even seen it happen on 1280x720 @ 240hz, I can press dot to dot and it actually renders in a LetterBox Borders and all!!!

but it's like in relation to 1920x1080 being the True Panel size!! truely if dot to dot worked the image should be Half of the size it is now...

I have noticed when I use graphic Programs which has the Checkerboard transparency or light grey images
you can actually see Lines down the Center of Vertical and horizontal axis!
 
Ok,

Where do I start!,

I have found that I have been able to make the scaler disable...!
DONT GET YOUR HOPES UP.. the TV Seems doomed tho unless some super programmer can re write the firmware from the ground up!

So I have just created a resolution of 2560 x 1440 @ 75hz. Ok fullscreen looks shitty
press dot to dot.. same shitty image

After going to the Engineer Menu (Menu ---> 2947)
going to DEBUG.. then overscan

you will see H size and V size as 2560 x 1440
now when I press left arrow on remote to make the H & V equal 1920 x 1081 (yes 1081) for some reason 1080 makes the image tear up into 2 sections

but what find out is, that anything below 1920 x 1080 makes the actual image shrink while in dot to dot mode

I have calculated we need to reach 0.75 of 1920 x 1080
so thats 1440 x 810... make that your new H & V size... everything inbetween is crazy corruption...

but when it hits the 1440 x 810.. image come as good as it gets...
------- DONT GET HOPES UP -------

Image is still all over the place but at least the image is readable...

it seems that SEIKI have used a firmware for a 1080P TV and in the firmware somewhere they have created EDID or scan settings directly for 3840x2160 @ 30hz

as 3840x2160 @ 31.5+HZ looks crappy...

but it is interesting to see the debug menu allow altering the overscan settings..

Things to NOTE... I have seen that once you alter anything in the overscan the image become frozen... Move your mouse.. GO ON... nothing moves... input from hdmi 1/2/3 to other then back.. to get your screen back.. but doing so resets any alterations to overscan you made...

the engineering menu overscan settings dont save after powerdown... tho I think maybe a memory stick is needed to save settings?!?!?!?!

I am so desprite for HIGH HZ... I am currently running 38HZ Blurry 4K as I write this and think... WHATS THE POINT... it's crap..

We have unlocked pixel Clock MHZ now..

I tried a 3840 x 2000 @ 45hz... It only uses up 310Mhz clock on the hdmi..

but scaler ruins the image...


Part 2...

Ok.. for those that wish to alter the scaler image... you can!

I find that in Engineer Menu.. ( these settings to actually save...)
MENU ---> 2947
In Picture
VIP3 & VIP4
there are some scaler settings..

I have seen that altering these settings have created the screen to be either sharper or more blurry and there are somewhat finetuning..
AGAIN --- Dont get your hopes UP ---

but at least you can alter the scaler to your preference...


------------------------------------------

What to take away from this..

SEIKI are absolute SHIT!

The overscan feature doesnt work properly...

I remember the days of owning a monitor.. we had pixel clocks to fine tune the image....
I feel overscan is the area that is suppose to fine tune the image tho it doesnt work!!!!!!!!!!!

--- Good Luck to the programmers and Users who wish to try give us scaler free resolutions ---
maybe its possible?! but I have learnt alot about this set now...

you should be able to make 2560 x 1440 look better with the scaler alterations...

for now it's 31Hz 4K desktop...
150HZ 1080p games...

Until my new bestest friend in the whole world comes and give us a 4K @ 32+ HZ clear image!!!!

Doing 1440p at 80hz here. Text looks like shit but every game I own looks fantastic.
I do 1080p@ 144hz and it's awesome!
 
rezzing the thread to ask if someone else is experimenting random self resets of the 39" during normal use 4k@30hz or 1080p@120Hz.:mad:

Also, how stable has been 1080p@150Hz for those that tried it?:confused:
 
I was but after changing HDMI cables and using a different input, it went away.

New firmware looks great but no sound. And more importantly, even though I can create custom resolutions like 1920x1080@120hz, almost every game uses 1080p@60hz...

Any ideas?

Only time I have typically had issues with 4k@30Hz or 1080p@120hz has been cable related. Once I replaced the cable both have been rock stable for me. I have rarely seen some issues with 240hz @ 720p only on the 39 inch model.


Since you get frame skipping at >120Hz I don't really see a point unless its double (and the frame skipping wont be ass off-beat) as the only real advantage I have seen is decreased input lag.

:eek::eek::eek::eek::eek::eek::eek::eek::eek::eek::eek::eek::eek:

Playing around with my Seiki (50" with Houkouonchi's firmware) just now, it seems that backlight level in the service menu affects motion clarity significantly. With backlight closer to 0 and brightness 100, motion clarity (and contrast incidentally) seems akin to my XL2430T and PG278Q TN panels, at 120 hz. This is pretty remarkable to be honest. If any of you would like to replicate, go to http://www.testufo.com/#test=framerates, and look at that test and the moving photo test. The street map in particular is perfectly legible. The alien invasion test shows crosstalk and ghosting comparable to the BenQ XL2430T without VT tweaks and strobe phase adjustment (with the clear area being at the top of the screen).

I don't have another large VA panel with comparable settings to test, but I doubt this is the usual behavior for this kind of panel.

Edit: It actually looks like it's engaging lightboost/3D mode behavior (albeit with comparably low contrast). Pretty nice to have such a large strobed display without knowing it!

back to the 4:2:2/ 4:2:0/ 4:4:4 problem.
according to this test image, my Seiki 39" works on 4:2:2 on my AMD cards at any and all resolutions.
ibyJcwdIniHUEs.png

I tend to believe it because my apple 30" shows 4:4:4
on the other hand the cheap samsung monitor at works shows 4:2:2

What are the definitive test images for 4:4:4, 4:2:2 4:2:0?
 
This firmware fixed my blanking issues, however, I now have no audio. Hah!

Awesome seeing progress!

*EDIT I just tested other inputs and I'm not getting any audio... is there something in the engineer or factory menu that enables/disables audio?

Hello,

After playing around a little..

I found out that

MENU --> 2947

using the VGA Menu and changing the numbers inside will result in overscanning/underscanning the screen...

I have tried for hours but didnt get purfect 1:1 image
It was alot better then what the tv defaults...

I liked the resolutions (3200x1800 / 2880x1620 / 3840 x 2000) try running highest hz you can... stay under 320-325MHZ px clock for good a strong... NON blinking display

I found making those custom resolutions and shrinking the screen the way I said to, it will look better. Much better...
there are also advanced options for color shifting and all softs.. Like I said No saves so thats a bummer.. Maybe it needs a usb stick for this to save as it is a service menu!!!!!!!!!!!!!!!!!!!!!

lastly.. the first menu there is some settings for scaler to sharpen the image. I like it sharper......


The bad thing is that it wont usually remember the scaler settings but the VGA menu it sort of remembers..
I notice if I change res, all I need to do is go into the vga menu and press OK twice on CLOCK..
that usually changes everything back..


So there we go.. I hope by some luck someone has a lucky night and creates a awesome 1:1 border resolution...
I feel that it's about getting the right combo on actual pixels & the VGA size/position/clocks...

I wish you guys luck.

Wow I see it! Too bad the IQ gets ruined...

What setting do you guys recommend for the backlight?

I ended up settling with backlight 20, contrast 35 and brightness 70 on the warm color setting. Contrast and color is excellent, while the gain in motion clarity is still evident.
 
Can you show/give examples? Considering this to use as a secondary 1440p monitor, but many on this thread are saying the 1440p looks like crap.

Well I'm on the 39 inch with the latest Seiki firmware that opens up the pixel clock and 120hz. At 1440p, text and everything looks like junk. However when I play Far Cry 4, Elite or Star Citizen it looks better than 1080p.

As for the 150hz deal, it frame skips some, at 140 it doesnt. Unless there is something I'm not seeing at ufotester.
 
I have noticed 1 weird issue and I am lost..

I have a Nv 750TI on 1 system and my GameRig has a AMD R9 290

The 750ti allows px clocks up past 297MHZ
the 290 wont show any resolutions past 297MHZ

I have tried the ATI Clock Patch, Doesnt work.. I use the latest OMEGA Drivers for amd too..

Anyone else found the solution?
Here I was thinking the JUNE 2014 Firmware allowed Unlocked 297 where as it was my Radeon all along!!!

I was wondering if you could post the firmware you are using? I am trying to get the 120hz and am not able to get it with the firmware that is currently posted on Seiki's support download page. Thanks!
 
You Seiki guys with 4k

What resolution does this site says you are using?

http://www.whatismyscreenresolution.com/

I want to see if the site is wrong.. I'm on 4k(changhong) but it says 1920x1080... I have some suspicions about this TV just need to be sure.

"YOU ARE USING 3840 x 2160"
Seiki 50" (SE50UY0) standard firmware. You can see the screen res by clicking on "Display" on remote.
Unless you meant something more complicated than all this info.
I'm just lurking for a 2160p at 60hz mod. That's all I want. :p Surely 1440p won't look great so I didn't even try that.

Even for me on linux it correctly says 3840 x 2160 for me. What os are you on? I think newer versions of windows can do similar to what os X can with its HiDPI mode where UI is basically treated as 1/4th the resolution. I could maybe see it incorrectly detecting the resolution if something like that is being used maybe?
