Seiki SE50UY04 3840x2160 50" TV ($1300)

1. I don't need HDMI.
Anyway, I need to buy new PC to get 4k@60hz.
I hope there will be a laptop with DP1.2 without Optimus and lighter than 2.3kg.
2. Yes
3. 1920x1080@120hz and 2560x1440@>=75Hz without scaling would be nice.

I hope your upgrade board will be able to ship to Japan.

How can you have 1440p on a 4k native display without scaling?
 
The issue comes from the display scaling. The seiki display scales anything that is bigger than 1080p but smaller than 2160p down to 1080p and then back up to 3840x2160.

Not all the displays are doing this. On the newer 39 inch displays I have seen it do better scaling (still not great) but its not doing this bs downsample -> upsample bs like both my 50 inch displays have done.
 
Hey guys, had my Seiki working great on my Nvidia system, however now I got it attached to a AMD 7950 system. Couple of questions:

How on earth do you keep it at true 1080p 120hz and not that 4k 1080p stuck at 30hz?

All my games now switch to 1080p but display shows 4k 30hz in info. How to make it work?

Tried searching this thread but way to huge.

Thanks!

Catalyst Control Centre
Desktop Properties
in Settings, scroll down until you see HDTV
Select 1080p.
Apply.


if HDTV isn't available.

go to My Digital Flat Panels
HDTV Support (digital Flat Panel)for the HDTV modes, make sure the 1080p50 format is ticked.

You can also choose from the list down the bottom, and add other 1080p or 1080i options as you like.

May require a reboot for the catalyst settigns to work.

Also, in HDTV mode you will have to change the Overscan option so that the video picture fills the screen.

Just did that. I can get 120hz on desktop at 1080p. However in every game I go into , the game itself is set to 1080p, yet the display info from TV is showing 4k 30hz still. Worse yet, Valley and Bf4 runs at 4k when my desktop is set to 1080p. Alll I get is a corner of the screen.

This was easier with Nvidia. So far there have been zero leads on how to make this work on AMD. BTW, this display wants to be stuck in YPbCr not Full RGB as well.

4 forums, 5 threads and no one knows a thing about how to make this monitor work with AMD reliably. smh.

EDIT: CRU does not do shit. Every goddamn resolution I pick, the thing stays on 4k (on TV info with remote) with some sort of shit scaling.

UPDATE: The ONLY way I can get Valley, BF4 and others to run at TRUE 1080p 120hz (on tv info and ccc panel info) is to set 1080p manually then force any game to run in a 1080P window. Not fullscreen native. ALSO now my display is flashing randomly at 120hz. This display works with ZERO problems on my 670gtx.

Well, I hope mine is one of the newer ones. I ordered my 39"back in January but can't pick it up until next month. The scaling problem is firmware related though, no?

Ive seen people say that different firmwares garners different results.

The latest firmware from this forum works great. I've had ZERO problems with the same display and Nvidia cards.

These pos AMD cards can't get their shit straight with custom resolutions.
 
Are you on the 39"?

What firmware are you referring to? The one with the custom resolutions built in? I'm guessing it has 120hz working without frame skipping too?

I was going to ensure the stock firmware for a few months to ensure I dont have any technical problems with the tv, and then apply the 50" firmware on it.

If there's a better firmware to use, please point me in the right direction and I'll download and store it.

P.s. I'm on nvidia. 670 gtx. Will likely get a maxwell once they are out.

Yes, the latest firmware from here has 120hz no skip. If anything running the monitor at 120hz and multiple resolutions will put it through it's pacing. The stock 39" firmware sucks at 4k. The latest allows me to play MMORPGs at max res.

You will be fine with the 670.

What do you mean it sucks at 4k? You mean in regards to input lag?

And where can I get this firmware? :)

I've been reading since page 20, and I'm not finding this firmware.

Can anyone tell me where to download the firmware, and any technical details about its changes vs the Seiki ones.

Thanks
 
I had an IBM T221 IPS Display 3840x2400 running at 31 Hz for over one year without any problems before I upgraded to the Seiki 39' 4k at 30 Hz. I do not game. I use the monitor for work and web browsing mostly. I guess if you game, the 30 Hz refresh rate may bother some users. Do most Xbox 360 or PS3 games run at 30 frames per second, if so I would say mostly users are not bother by the low refresh rate.

I set my Seiki 39" sharpness to Zero which helped a lot with the burry text.

Yeah, PS3 and Xbox games mostly run @ 30fps. And a lot of "non hardcore" gamers, surely run games in the 30fps range too, it takes a pretty high end video card to run triple A games @ 1080p + with max settings and Antialiasing. I have a 670GTX, and I usually tone down a bit of shadows, and run FXAA just to maintain 60fps @ 1080p.

Either way, a lot of the people that complain about 30hz, probably don't even realize they are gaming @ 30fps in a lot of situations, on PC and Consoles alike.

I think he is talking about the 50" Firmware, you can find it on the seiki website.

The 50" firmware works on the 39" and makes 120hz 1080p work properly.

kk, I already have all those, the way he worded it, it sounded like there was a custom firmware that people on this thread had been using.
 
Ok. So this one is just the 50" latest firmware with an extra 120hz resolution in the EID?

Pretty much but oddly enough I saw reduced input lag on it on my 50 inch compared to the stock 50 inch WTF? and also the menu is slow in 120Hz now which it wasn't before... Its odd. Maybe something with just how I modified it and checksums not matching it does something that reduces the input lag, atleast that was in my case. Will work on the 39 and 50 inch. It is based off the 50 inch model's newest firmware.
 
Hey, when you guys say the input lag is reduced, do you mean for specific modes, or across the board?

Like, would 4k30hz, 1080p120hz, and 1080p/720p60hz from a console be reduced?
 
As a summary of what I have learned by experience after owning the 39 inch model:

The display itself:
  • Do the firmware first, it wipes your settings after you upgrade.
  • You have 2 options for the best experience, use the 50" firmware from Seiki's site to get 1920x1080@120 and 3840@2160@30/31 lag reduced or use houkouonchi's modified version of this software which adds 1920x1080@120 to the display advertisements so you don't have to do it later. Both have the same annoying amount of lag at 3840x2160 (about 80-100ms more than 1920x1080@120) but do a good job. Seiki (it's the only 50" firmware) http://www.seiki.com/support/downloads.php and houkouonchi's http://box.houkouonchi.jp/seiki_firm/install.img
  • To perform the upgrade extract the install.img file from the zip (already done on houkouonchi's) and copy it to a FAT32 USB drive. Once this is done remove the USB and put it in the port on the TV (by HDMI 1 and 2, on the bottom) and go to the menu. From there enter "0000" (make sure you aren't in a submenu or that won't work) and the service menu should pop up. Navigate to Software Upgrade, hit right, chose yes, and wait as the TV upgrades. The power light will flash between blue and orange, this is a good sign. Once it is done the TV will reboot and your firmware is now upgraded.
  • If you chose a 50" firmware you'll probably notice the picture looks a hell of a lot better already, that is because the sharpness setting is broken (a good thing in this case). If you have an updated 39" firmware setting sharpness to 0 disables it just the same. On a really old 39" firmware you need to go to the service menu again and under "Others"->"Video Quality" set it to 0 as the normal menu won'l let you go below 22 even though it says 0. There are a few other safe options you can change in the service menu but they don't really get you much worth mentioning and there are a few that will screw up your display so if you aren't certain don't click it.
  • Another setting you can change is in the normal menu under "setup". "Noise reduction" doesn't seem to change anything (maybe it's broken like sharpness?) but I set it to off anyways.
  • http://www.lagom.nl/lcd-test/contrast.php is a great site to see how well your image is calibrated.
  • That's about all you can do sadly, still a bit laggy in 3840x2160.

AMD:
  • Have an older AMD Card? You don't probably don't need to upgrade just run this to remove driver limitations (worked on my 6970, reportedly 4k works on 5xxx cards even) http://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher
  • Use the CRU http://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU to add 3840x2160@30, 3840x2160@31, and 1920x1080@120. If you have more than one monitor make sure you add these to your Seiki. Use the LCD Reduced timing preset when adding the custom resolutions and make sure you uncheck "include extension block". You can add 1920x1080@124, 1280x720@240, or 1280x720@248 and it will accept them but the panel only updates at 120 anyways. 2560x1600@60 is will work but obviously has to be scaled and isn't worth it in my opinion. The display accepts all the way to 3840x2160@34 in my experience but anything beyond 31hz activates the scaler making it very fuzzy.
  • I can't find a way to set the resolution and refresh rate but once you have patches the driver, set up your resolutions, and rebooted you should be able to use the windows screen resolution dialog (right click the desktop or search the control panel) to set the resolution, advanced settings->monitor to change the refresh rate. If you don't see 120hz when it is set to 1080p or you don't see a 3840x2160 option make sure you followed the directions above properly.

NVIDIA:
  • 650 or newer should auto-start 3840x2160@30 out of the box, if it doesn't make sure you have the latest driver.
  • In the NVIDIA control panel->Diplay->Change resolution section you should see a "customize" button under section 2. If it is grayed out try reloading the control panel and clicking it before anything else, seems to be a bug I run into a lot. Once in check "Enable resolutions not exposed by the display" and click create a custom resolution. From there follow the instructions for the CRU utility mentioned above except "LCD reduced" is called "CVT reduced" in this tool. For some reason I had to add these resolutions in CRU and reboot before it would pass when I hit "test", nobody mentions this so it might just be me though.
  • once you have your custom resolutions (make sure you have them checked in the "customize" window after you have added them" you should be able to use the NVIDIA control panel to switch rather than the Windows method but both will work.


I really don't get why 3840x2160 has so much lag, it's not like there is any more work than 1920x1080@120, bad software design I guess. Otherwise the display is great!
 
AMD:

Consider yourself very lucky if you can get these AMD instructions to work with the modded Seiki. Display will show 1080p60 on tv info, scaling looks like hell. Also 1080p60 will force YPBCR instead of 4:4:4 rgb if in 'HDTV' mode. If you manage to get it in PC mode of 1920x1080 120hz, then scaler goes back to rgb and display is clear, however get mean jpg like banding in the blacks and dark colors. Of course, you will have to force your games to run in borderless windows as when it is full screened, it'll switch to 3820x2160 30 hz mode on tv info and 1080p60 in actual games. Not to mention it will switch back and forth and sometimes make game res huge so all you get is a quarter of your game (showing 4k res at 1080p60 or pc mode 1920x1080 with a scrunched up display). When the display is in 1920x1080 120hz pc mode, it's pretty clear and nice however it blanks out every so often. This was reported by other users as well.

I tried this on several computers with clean installs and AMD cards 7850 and 7950. Only 4k Desktop mode is reliable. I was able to get gaming work at 120hz 1080 PC mode and it was as pretty as the Nvidia cards.

The Nvidia instructions do not need even to set custom res the latest custom firmware is on it. Took to my two nvidia cards no problem.

I basically ditched the AMD card for Nvidia as AMD card next to impossible to keep reliable resolutions in gaming and all the CRU bs.

Hi folks,

Has anyone been able to hit something like 90hz @ 1920x1080.

Now before anyone comments about 120 being a perfect number for both 30hz and 24hz content, I will never use 1080p for desktop, simply for highly demanding games.

I have a 670GTX overclocked, and I don't get anywhere near 120 FPS constant, so running @ 120hz (I like Vsync) makes no sense for me, since I'll likely always be dropping frames (that's what vsync does when it hits less than the refresh rate).

Bottom line, I'm way more likely to get 60fps constant, which is fine for 120hz, and when I can hit something like 90hz, I'd like to take advantage of the extra frames, but honestly don't find myself even being in a situation where I get a constant 120fps.

So, has anyone with the same mindset as me tried 90hz ish @ 1080p?
 
UPGRADE OF 39" and 50" SEIKI TO 4K@60
Hi guys
I have a good message for you. It looks like we will be able to provide "4K@60Hz upgrade" for both 39" and 50" Seikis.
The upgrade should consist of:
- new Tcon board (to be replaced in the display itself)
- input board (1 x DP 1.2 input, no other video inputs)
- necessary cables
- new metalwork which matches connectors present on input board (DP, USB)

This MEANS you will not be able to use Seiki's proprietary board with all its input connectors etc, because it will be physically removed from the TV due to upgrade.

Endpoint:
- true 4K@60Hz via 1 x DP 1.2
- significant reduction in input lag!!!
- you will still get audio coming via DP 1.2 on Seiki's speakers (our board will have audio out connector)
- USB hub to connect keyboard/mouse or other devices
- you will be able to use Seiki's remote control to power on/off the TV
- you will be able to use Seiki's buttons on the side of the TV
- the functionality of Seiki's blue LED should stay the same
- the IR controller commands can be forwarded by USB to your operating system


NOW, a few questions on you:
1. Do you still need any HDMI 1.4 input which is capable only 4K@30Hz? (There are no HDMI 2.0 chips yet available.)
2. Would you go for this solution, even knowing you will loose your Seiki's board with all its inputs (TV, tuner, coaxial, 3 x HDMI 1.4, VGA etc.)?
3. Any other "MUST HAVE" or "NICE TO HAVE" features I have not mentioned?
Sinuhet

- Will the DP 1.2 port also do 1080p @ 120?

- Any chance of adding a HDMI 1.4 port doing 1080p @ 120 in addition to the DP so I can use the display with my bluray player aswell?
(using the pixel doubling method rather than scaler)

- If there is to be an HDMI 1.4 port as well it would be nice to preserve the existing HDMI 1.4, 4k @ 30 functionality while were at it.

I'm using Geforce650M(Optimus) + Intel HD 4000.
I can add 1920@1080@94Hz(CVT-RB) mode using customModeApp and TV info shows 1920x1080@94Hz.
I think you need to add custom resolution 1080p@90hz with CVT reduced in Nvidia control panel.
 
Hi there

just found this thread. Lots of great info. I see a lot of talk about the 39 and 50 for modded firmware and settings. What about the 55. I just got this about a week ago and still in the return window. Does anyone have the 55 and been able to mod the firmware?

No 55 inch firmware is available from anywhere to download and even then its completely different hardware so I would not expect good OC'ing =(

Yes, I was wondering the same, also am I a bad person for asking for a possible ETA?
I sold my seiki 39" purely because i couldnt handle the 30hz anymore, but would buy it back in a heartbeat if i could do the upgrade.
1. No

My Answers:

1. No. I solely use my 39" Seiki as a computer monitor so a single input is all I need
2. Yes, see answer to #1
3. Not a deal breaker by any means, but a "nice to have" would certainly be to have the display support DPMS for sleep/resume. Again, not a deal breaker by any stretch.

My questions:

1. When can I buy it and how much will it cost??
 
About storage reading speeds, the timescape site, that sells a 300GB 4k movie, recommends RAID arrays or SSDs. i will test the roasted duck movie with a low quality SD card and report later. the ideal test scenario would be a film bigger than available memory so we can actually see if the storage solution can really fill the buffer fast enough.

updating: on my 16 GB machine the film stutters every ~2m30s which is roughly the buffer size available. my next machine will be a multi core AMD, if only because AMD is compatible with higher density memory modules.
 
Im interested in a diy 60hz display port mod.

I use a 39in
Whats involved with the change over.. how advanced would soldering be?
Timeline to release.. are the boards ready soon?

Yes......please answer these questions to the best of your ability Sinuhet!!!!^^^^^^^^​
 
Avoid this monitor like the plague if you have AMD. Several forums and not a single self proclaimed PC nerd has the skill or the ability to make this monitor work at 120hz gaming @ 1920x1080. Not a single one even breaths a word on how they got it to work other than the same CRU-CCC circle jerk that does not work and never has on 3 machines, 2 operating systems and 2 AMD cards.

Nvidia it works fine.

Moral of the story: Never go Red, EVER.

I think you are doing something wrong. Worked first try for me.
 
I think you are doing something wrong. Worked first try for me.

Prove it. I got a machines here clean installed with AMD 7950, the latest 14 catalyst,. the latest CRU and the latest firmware on the TV as well the last custom INF. What date is your custom inf? What custom firmware did you put on? the second or the first modifed one?

I can sit at 120hz desktop all day long. However not a single game of any type will run at 1920x1080/120hz. Not. a. single. one. The display/desktop stays at 4k and the games are all forced to full screen at 30hz 1920x1080 scaled. Does not matter if gpu scaling is off or on. Then when you set the desktop to 1080p 120hz, every single game comes up massive or black screen.

This is all on Windows 8.1 64 bit and Windows 7 64bit.

At this point It's been weeks. Had several self proclaimed forum nerds from OCN and AVS forums help out remote screen and over the phone. I even offered money!
