Seiki SE50UY04 3840x2160 50" TV ($1300)

Hey Houko, does the 39" handle 240hz at lower rest like 720p?

It will take a 240Hz signal but it only helps in reduced input lag (~4.5ms instead of 9ms) which was barely noticable on quakelive (back when they still had a linux version and I played it) but it can make the difference to me (who is very sensitive about input lag) to just slightly noticing a very small amount of input lag and not being able to tell there is input lag at all.
 
The buzzing is odd. I haven't noticed that on my 39 inch displays but I did notice my yamakasi did hiss/buzz a little bit when it was doing 120Hz. Unlike the yamakasi the seiki is not really being overclocked at 1080p@120Hz. The internals for the actual monitor portion should be under no additional load (same bandwidth/strain as 4k@30Hz). The only difference in strain is at the TCON -> panel but the panel is fully spec'd for taking 120Hz full HD/1080p input and even has the timings on its spec sheet so its within spec.
 
I just bited the bullet on a Spyder4express. as soon as amazon delivers it here in brazil i will post results.

Thanks to all of the information in this thread I picked up a 39" and got it set up as my monitor at 4k. I'm really liking it except for the input lag which is extremely annoying, possibly to the point of returning it. I updated the firmware to the 50" version but am not sure what else I can do. Doing things that require fine mouse control, such as Photoshop, is really frustrating. Even normal PC usage is frustrating since I have to pay much more attention to what I'm doing with the mouse to make sure I click where I want to.

I turned of vsync in the NVIDIA control panel (Manage 3D settings -> Global Settings -> Vertical sync) but was wondering if anyone has an idea of something else I can try to reduce the lag. I experience lag with typing as well and when I really get going it can be 3-4 characters behind what I'm typing but that doesn't bother me nearly as much as the lag with the mouse.
 
Hey Houko, yeah im also pretty sensitive with the input lag/response. I can clearly see a difference between this and my 120hz samsung S27A950 TN panel. But im happy to accept this over the TN due to size and colors/contrast advantage, its rly no contest hehe.

So it will accept 240hz, and will it display all 240fps as well? Or skip each odd frame etc, as it was the case before the firmware with the 1080p120 mode. Just as a muck around, i wouldnt mind seeing 240fps hehe, maybe even encode a slow motion vid into real time with 240fps hehe.

It only draws half the frames, it won't actually refresh at 240 times per second, so it doesn't get any smoother; however, like I mentioned the input lag was definitely decreased when I ran it at 720p@240Hz.

I know most people wouldn't notice the input lag at all as it is very low but some of us are very sensitive to it.

Maybe try disabling aero to see if its better. I know the input lag seemed a lot worse on windows than it does on mac or linux. AFAIK there is unfortunately no way to disable vsync with aero.
 
Just picked up my Seiki 39 today. Question though: I seen two firmwares for the 39
39” Seiki 4K Ultra HD
Model # SE39UY04 – 20130827 click here
Model # SE39UY04 – 20130828 With Backlight And color TEMP click here

And this one for the 50

50" UHD LED TV, 4K2K, 120hz
Model # SE50UY04 click here
Changes to EDID timing for better handling of UHD resolution.
Fixes audio issue that was caused by previous firmware.

I should use the 50" firmware, however what does that second 39" firmware fix?

Thanks!

I believe the 39 inch firmware also had timing/EDID fixes in it and the second one also included backlight/color/temp controls from the main menu (instead of from the service menu).

If you want 120Hz 1080p, no auto shutoff after a few hours and better colors/input lag then go with the 50 inch firmware. It is highly recommended.
 
Aloha,

Just did it. Not to bad of a display!

Any wya to make text a lil better?

Also 120hz is only set by Nvidia or cru, how about when I use HDMI for xbox or dvds? Does it auto detect 120hz?
 
I am very happy with my new SE39UY04. I'm using it for screen real estate. I previously had a 37" 1080P Westinghouse, but wanted more pixels...boy did I get more pixels! I did bump up the DPI setting in Windows, but I'm just loving the large desktop. Amazing deal for me (Amazon $399). I know it's only 30Hz, but I don't really notice. I am anxiously awaiting the promised firmware though....
Great thread guys for a great montitor
 
Also looking forward to the new firmware. Although its seems to be more vaporware/rumorware at the moment with no clarity on a delivery date, if any...

If you haven't already turn sharpness to 0 then text is super crips/clear.

120Hz is currently just on a computer (nvidia or AMD).

I will look through the firmware dump and see if I can make a custom EDID firmware mod so it can work on other devices.

Yeah.. I setup a script that is checking the firmware page for updates so when it does happen I will definitely let everyone know.

Using the 50 inch firmware in the meantime is a good alternative I think though.
 
i tried the 50" firmware, lost the audio out from the 3.5mm jack. flashed back to the 39" firmware until my coaxial->optical adapter comes in for my sound bar.
 
Found the EDID. Its in 'dvdplayer'

So i can probably hack up the EDID and package my own firmware (with a new boot logo too maybe? =P).
 
So I am having a problem flashing my seiki with a new install.img I made. Maybe the verison of squash I am using is causing an issue but the flashing process seems to never finish when I tried my modified dvdplayer with a modified EDID.

Here is the modified DVDplayer for anyone else who wants to try:

http://box.houkouonchi.jp/DvdPlayer

Also I made a new .inf that has the 60Hz modes taken out. I tested the EDID with my linux machine and here is what it is seeing as far as timings from EDID:


root@dekabutsu: 02:15 AM :~# cat /var/log/Xorg.2.log | grep Mode\ Source:\ EDID -B18 | grep @ | sort | uniq
(II) Feb 21 01:18:38 NVIDIA(GPU-0): 1024 x 768 @ 75 Hz
(II) Feb 21 01:18:38 NVIDIA(GPU-0): 1280 x 720 @ 240 Hz
(II) Feb 21 01:18:38 NVIDIA(GPU-0): 1280 x 960 @ 60 Hz
(II) Feb 21 01:18:38 NVIDIA(GPU-0): 3840 x 2160 @ 24 Hz
(II) Feb 21 01:18:38 NVIDIA(GPU-0): 3840 x 2160 @ 25 Hz
(II) Feb 21 01:18:38 NVIDIA(GPU-0): 3840 x 2160 @ 30 Hz
(II) Feb 21 01:18:38 NVIDIA(GPU-0): 640 x 480 @ 75 Hz
(II) Feb 21 01:18:38 NVIDIA(GPU-0): 720 x 480 @ 240 Hz
(II) Feb 21 01:18:38 NVIDIA(GPU-0): 800 x 600 @ 75 Hz

This might work better for those of you who have problems with some games not wanting to do 120Hz at 1080p because the 60Hz mode still exists.

The inf can be found at:

http://box.houkouonchi.jp/seiki_240_120_only.inf

I haven't had a chance to try it on a windows machine though. Maybe someone could give it a try and see how its working. I dont see any issues testing it as u can always uninstall the inf if it doesn't work right.
 
I used 7-zip to replace the boot logo in install.img and wasn't able to get it to flash either. Just got the flashing blue/red indefinitely until I power-cycled the TV.

I got it working. I tried a few different things after looking at the raw .tar file comparing to the one I made. I setup my machine so uid 1001 was the same username (hanyuntan) as the in in the install.img and instead of taring from the current directory (using ./ so all paths were appended with ./) I instead did * so the paths did not have ./ appended to them (like the seiki install.img). this time flashing worked. If anyone wants to give it a try:

This is the 50 inch 5/28 firmware but modified EDID.

It makes the display show up as Seiki Mod

And it has 1080p@120hz and 720p@240 Hz as part of its EDID which means it should allow 120Hz modes with other devices (that support such modes).

The 1080p 120Hz mode is the actual CEA EDID mode that is an actual standard so I would think if devices work with other 1080p 120Hz displays it would work the same way with this one.

If someone has a good replacement video to add on to the firmware I can do that as well =).
 
Oh, I almost forgot.. I also took out the YCbCR support in the EDID as this has been fucking with the colors for people and it seems some people have had issues disabling it so I removed it from the EDID on my firmware hack:

Also.. this could be my imagination but I swear it feels like there is less input lag now. I don't see how my changes would have made a difference though. Odd!

Like playing an FPS (although low frame rate) seemed to now have low enough input lag @ 4k to actually be playable.
 
Oh, I almost forgot.. I also took out the YCbCR support in the EDID as this has been fucking with the colors for people

This is great news, because i am tired of reading dumb photographers usings Macs reporting banding and 85% sRGB color coverage for this TV. Since most of them are computer illiterates that cant set sRGB in the GPU control panel, the safest way to work is to remove completely any support for YCbCr on the firmware EDID.

Trick question: does EDID carry info on pixel alignment as well? Can we make the EDID explaim to the PC that it is a BGR pixel order, not RGB?
cause also some photographers are cursing the TV and blaming the scaler or whatever for wrong cleartype settings on their Macs.:rolleyes:

Would it be too much if i manually used the service menu to fine tune the color offsets/color gains with help of the spyder4xpress and later you burned the hardware calibration on the firmware? Being a LED panel such calibration would be correct for a very long time, because LEDs age slower than CCFLs, and LEDs are more uniform along the production line, so at a given backlight level most users could benefit from my calibration efforts.

Nice rant. However you are talking out your @ss. EDID Modifications/overrides for color space on OSX have absolutely no effect in Mavericks with this display. Your level of knowledge in OS X and interactions with this display is clear. I'd be interested to know, where in the displays preference pane can one change color space? Because is doesn't.

FWIW... Modifying/overriding the edid removes any support for audio or extended display features.

Not a photographer but a software/hardware developer.

Over-riding the EDID shouldn't have that effect unless your EDID override is an older non EDID 1.3 override which is like half of the size. The one I did has a lot of the additional HDTV info that the seiki has as well. I haven't tested to make sure HDMI audio and stuff was still working though.

I am not aware of anywhere in EDID where sub-pixel ordering is stored.
 
Definitely seeing some behavior changes. I now see @ 120Hz the menu is very slow just like i was seeing with the 39 inch with the 50 inch firmware model but now my 50 inch is doing it with my custom firmware.

Also I am almost sure the input lag is lower at 4k atleast on the 50 inch display, its odd.

If anyone didn't know (color saturation issue when scaler is active) you can change the color via the service menu (i have it near 100) it will save it for the mode if after you make that change change the brightness or contrast a little from the regular menu and when u switch between 4k/1080p@120hz the color settings get saved for the mode. I knew this before but realized I hadn't seen if anyone posted it.

Please calm down, i think there is a bit of misunderstanding going on, which coupled with the natural reactions i have to Apple users can quickly escalate to a flame war.:cool:

I will retrace the thread and relist the problems and solutions found so far in this display which is AFAIK the most challenging to setup i have ever heard of since i joined the [H] community.

1-TV is not recognized by the PC, is recognized but at 1080p60Hz, only accepts 4k@18-24Hz, not 30Hz.

-Hardware solutions: change HDMI port, use a displayport to hdmi 1.4 active adapter.
-Software solutions: use a custom .inf driver from houkouonchi and/or override the EDID information stored in the OS with Toasty's CRU. The later does not work on Intel IGPs and inside OS X.


2-TV finally displays 4k@30hz, but with banding, reporting low sRGB coverage. Also black crushing.

-Software solutions: Both NVIDIA and AMD use YCbCr as the default color model for this TV. In AMD, click the box on "use EDID information", on NVIDIA simply select RGB as color mode.

-Alternate solution: hack the firmware update file provided by Seiki, locate the EDID and remove the support for YCbCr. According to wikipedia' s page on EDID, there is a byte that does exactly that, WITHOUT MESSING UP THE HDMI SOUND STUFF. This solution would allow for correct color model selection in Linux and OS X machines. This is not an EDID "override" inside the OS, it is actually flashing a modified EDID inside the TV.


3-TV shows text with a blue/red halo.

Software solution: use whatever utility your OS has for cleartype-like subpixel rendering to inform the PC that the TV does not use the RGB subpixel order, but BGR. As houkouonchi and wikipedia told us, it is not possible to codify this information inside the TV firmware.

I got it working. I tried a few different things after looking at the raw .tar file comparing to the one I made. I setup my machine so uid 1001 was the same username (hanyuntan) as the in in the install.img and instead of taring from the current directory (using ./ so all paths were appended with ./) I instead did * so the paths did not have ./ appended to them (like the seiki install.img). this time flashing worked. If anyone wants to give it a try:

http://box.houkouonchi.jp/seiki_firm/install.img

This is the 50 inch 5/28 firmware but modified EDID.

It makes the display show up as Seiki Mod

And it has 1080p@120hz and 720p@240 Hz as part of its EDID which means it should allow 120Hz modes with other devices (that support such modes).

The 1080p 120Hz mode is the actual CEA EDID mode that is an actual standard so I would think if devices work with other 1080p 120Hz displays it would work the same way with this one.

If someone has a good replacement video to add on to the firmware I can do that as well =).

Does this play well with your original inf? And I noticed that a 1080p @120hz was not on the short list you gave. All included, yes?
Also does this effect any other inputs like TV or xbox etc?

Yeah the inf will still work... 1080p maybe isnt listed in the nvidia linux logs because its a CEA mode and not detailed timing mode listed (mode 63 on CEA). When I tested it on my macbook pro (on windows) it correctly had a 120Hz mode for 1080p and 240Hz for 720p (the 720p one is detailed timing mode).

Unfortunately the glossy wrapper of OSX lacks control of color space and edid override is rather primitive. If one overrides one component of the EDID in software, audio features are lost. Any extended features beyond base resolutions must be redefined within the software based definition, otherwise they are lost. Apple uses EDID overrides for colorspace control.

I've been able to inject a code based override with the Seiki 39 initially developed for fixing an issue with a Dell display on OSX, although changing the colorspace to full YCbCr or RGB has no effect and appears to be ignored once implemented.

Running a flashed AMD 7950 with the 50" firmware, once the display sleeps, OSX will not reinitialize the upon wake. I need to try again with the GTX 680 I'm currently working with.

While the colorspace is corrected with the 50" firmware. Shadows around windows have "dancing pixels" in the transparency area and a bit of a red hue after hardware based calibration. If I try to correct the small issue, it mucks with the overall image.

For color calibration, I use a Huey Pro I purchased back in 1997. Calibrating the seiki delivers an image with a slight red push. To compensate, I calibrate the display set to "warm" and switch it to normal post calibration. That said, the resulting color quality, even with the 39" firmware is spot on and Pantone accurate.

If you have an OSX EDID override to share, please post a link. I've discussed the issue in detail with the developer of SwitchResX looking for details into Apples file format, but wasn't able to find what was needed to reinject audio, let alone the color calibrations created by the Huey Pro. SwitchResX is A must have for working with the seiki on OSX. It works but keeps me wanting more. I miss the days of powerStrip by entech.

Regarding HDMI on AMD cards and OSX... I've been on the Apple Bug reporter merry-go-round, having many interactions and pushing Apple to fix code based on HDMI specifications from before 2006. kudos to Nvidia for providing a working HDMI port @ 30hz.

Over-riding the EDID shouldn't have that effect unless your EDID override is an older non EDID 1.3 override which is like half of the size. The one I did has a lot of the additional HDTV info that the seiki has as well. I haven't tested to make sure HDMI audio and stuff was still working though.

Cool, thanks for being so helpful!

What does DCC do? I seen that on and off on some people's menu settings.

I think its "Dynamic contrast control" but from what I have seen the display doesn't actually support this or do anything because I haven't ever seen the type of effects ive seen on other panels that do support dynamic contrast control.
 
Ok, tried out this new img file. I simply cannot make games run at 1080p. The games say 1080p, the display says full 4k with 30 hz. In game fps counters say 30fps.

Desktop 1080p 120hz works just fine though. Thinking I'm going to have to switch back as 1080p 120hz does not happen. With old and new INFs.
 
For games, i find that games happily run at 1080p120hz if your desktop is also set to 1080p120hz. Which is weird. Yeah so if your desktop is running 4k30, and your games' config ini is set to 1080p120hz, it can have issues. But switch your desktop to 1080p120, and all the problems suddenly vanish hehe. This is using the stock 50" firmware.
 
Yeah, the last firmware switched modes better. This one takes some force to not let the games run at selected resolution. In ARMA 3 I have to run in windowed full screen to make it work.
 
Have you tried using Custom Resolution Utility along with houkouonchi's custom inf file? The only way I could manage to get the display to force 120Hz without getting strange artifacts that looked like pixel flicker/twitch was by using all three. The steps that worked for me were:

1. run the reset all app that came with CRU and reboot.
2. run CRU select import and find houko's custom inf. select it move the 1080p above all other defined presets. uncheck hook option and reset.
3 For me personally I had to make custom resolutions following CRU setting under nvidia control panel. Using this custom firmware you can change the resolution using windows change screen resolution. In order to change from 60 to 120 under windows you have to go under screen resolution advance settings and click on monitor you should be able to switch from 60Hz to 120 there. I prefer using NVCP and creating the custom resolutions using the manual settings that hou provided.

Issues that found strange were:

Don't use the inf to update the monitors driver. It causes some weird pixel image doubling that moves kind of like some really bad gif.

Switching from 4k to 1080p keeps the monitor at 30hz. Changing the input source via remote or powering off and on the set resets it at 120hz.

Sometimes when switching resolutions the displayed resolution is zoomed into a corner and looks terrible resetting the display usually fixes it once it did not..and very rarely by switching resolutions the strange gif like artifact came up.

Sorry English is not my first language. Thank you houkouonchi for providing all of these fixes and information that without I would have considered this display beyond terrible Seiki could really use someone like you :D. My computer info is:

EVGA 670 FTW stock. Windows 7 64. Intel 3570k @ 4.0. g skill ares low profile 8g. biostar z77 E3.
 
I found running the display in VGA mode lets you run games at 1920 * 1080 without any of the mode-switching problems.

As well as your HDMI cable, hook up a VGA cable to one of your DVI slots (with a DVI->VGA adapter) and then you have -two- displays to choose from. Switch displays with the remote control. Make the VGA primary when you want to play a game, and bob's yer uncle.
 
Great. I'm now stuck at 1080p, no matter what. Reset the drivers, graphics drivers, CRU reset utility..nothing. Is my TV broken now?
 
Only negative about using a connection like that is that VGA can only go up to 60Hz at 1080p. Also by switching preferred display from VGA to HDMI I found that the refresh rate was unusual and still required the display to be turned off then on and to only have one display active at a time in order to get a valid 120Hz.

Personally for me booting into HDMI 120Hz from my computer and using NVCP to switch into 4k at 30Hz with manual custom resolution settings is a must. Going from 4k to 1080p without turning off and on the display always messes up the refresh rate and once made a strange moving pixel artifact that at places looked like funky tetris and at others like image doubling.

A possible fix might be using a displayport 1.1 or 1.2 to hdmi 1.4b active converter like what this reviewer bought http://www.amazon.com/review/R2FEYK...e=UTF8&ASIN=B00DOZHLAA&nodeID=541966&store=pc. Maybe then it would be possible to have 4k using seikis cable directly to your videocard on HDMI 2 and having 1080p using a high speed hdmi cable along with the displayport adapter into HDMI3 and duplicating the displays with one set at 4k and the other at 1080. Depending on your income it might seem like an annoying extra expense just to run your display at it's "supported" resolutions.

For me I get no issues whatsoever running games at 1080p 120Hz under 1080p desktop settings.So far I have tried Chivalry: Medieval Warfare and unlocked its framerate limitations from 62 to 120.I have verified before a refresh at 120 before and after game play and FPS of 120 using Rivatuner.

I wonder how many headaches would have been saved and profits made if seiki had built this display with a display port input instead of VGA which makes no sense if you market your TV to have 4k resolution and a basic computer input. It also looks like seikis new line of displays will have ancient VGA along with composite and component input which I guess people in the market of buying a cutting edge one grand display of 2014 will surely need :rolleyes: . Frank Kendzora you had one job.
