So I recieved my 39" Seiki 4K a few days ago and I'm living a nightmare trying to get 4K to work.
I purchased the Accell active adapter (mDP > TB), I updated the television firmware (was reading that the 50" works too, but I'm waiting until I can get 4K working) and downloaded SwitchResX.
I currently use a 2012 Macbook Air (Intel 4000) running 10.9.1 (I had to upgrade to so I could use Final Cut 10.1) and I can't get any custom resolutions in the display options other than 1080p, 1080i, 720p, and 1600 X 900.
The most frustrating part is finding a solution that works. I've tried going into SwitchresX and creating custom resolutions that people have found success with on the internet, but even after saving and restarting my computer, the status still says not installed. What am I missing?
I understand that since I'm running Mavericks (10.9) I can't install the Tom patch for higher monitor frequencies, I just want to get 4K at whatever Hz works.
Is there a solution that I'm just passing over or is my computer just not compatible? (I've read that people are getting even getting 4K on the 2011 Mac mini). Thanks!
If anyone can work out how to get the display to look how it does at 1080p@30hz when using 1080p@120hz, I will love you forever
Currently something weird is happening and at 30hz everything looks as you would expect, great crisp text, great colors etc... but going above that and weird shit happens
Try setting to 1920x1080@30hz and see how good it looks...
I had it displaying the full res AAAAxBBBB @ blah for ages... still can't get above 30hz to look as good as the 30hz does.. i mean its almost like when at 30hz it is running a different pixel format and what not, looks so good :/
I just flashed the 50" firmware on my 39", it works.
EDIT: Sharpness setting in the menu doesn't function, you can change the setting but it doesn't change the sharpness at all. (correction, it seems to work over HDMI but not DVI, wierd)
I was using the sharpness setting as a form of pseudo anti-aliasing at 1080p to make text look better, but I cant do that anymore. 4k reso is fine obviously.
EDIT: Mouse lag at 4k is MUCH improved with the 50" firmware. With the 39" firmware it was pretty unbearable to me and I found myself using 1080p constantly. Now I have no problems running 4k.
When you go to the software version in the hidden menu does it say Baseline: 522712. Just want to make sure I have the latest one, since this shows May 21 2013 compared to August for the 39".
I notice the same significant mouse lag decrease over the 39" firmware. Now it feel almost normal like you'd expect, and you only see an impact of the 30hz in terms of mouse trail smoothness, which is perfectly fine.
Very nice looking TV but sucks for gaming. 30hz looks like ass

I can do 35hz @ 4K on my Sieki with custom timings but the screen gets all blurry at anything above 30hz. The OSD does say though 3840x2160@35hz.
I just got this monitor at work.
How do I find out the current version of firmware it has?
I joined the forum just to post in this thread.
I recently jumped the gun on 39'' version and upgraded it to the 50'' firmware. I also used the settings for custom ToastyX settings.
It is connected to a pc running a gtx 770 2gb.
I have to admit, I have not read each and every page of the thread, so I apologize if I repeat anything that's been already said.
A few things to note:
-120hz works now. I will update this post with proof.
-There is still some ghosting at 120hz even though the UFO test validated true 120hz. This is the most noticeable with simply moving the mouse.
-Gaming at 1080p@120hz is fine and the colors are NOT washed out. However compared to 4k gaming, the colors look much better at 4k
For 1080p MKV blu rays:
-Watching movies at 1080p@120hz looks washed out and faded compared to 4k@30hz. In dark parts you can see pixel artifacts of the previous scene.
-Movies are doable at 4k@30hz. It just looks like a big movie theater screen
-There is a bit of a difference between 4k@30hz and 4k@25-27hz -most notably in color saturation and blur. 30hz looks great. 25-27 is when motion blur starts rearing its head.
What we need to fix:
-Color saturation and quality with 1080p@120hz.
-Motion blur/lag/ghosting with 1080p@120hz.
I was thinking of adding Lightboost tonight, but I haven't seen anyone use it alongside the firmware "hack" nor does it look compatible.
Yep, that's me.
Thanks, I just found out how to access the service menu (MENU, 0, 0, 0, 0), and the version info is there. Next up I lowered the backlight brightness, so it's much easier to look from up close now. I've already set sharpness to 0 (made a big improvement), and turned noise cancellation off (didn't see any difference).
Some more details:
-Seiki 4K 39" SE39UY04
-15-inch, Early 2013 Retina MBP (GeForce GT 650M 1024 MB)
-Running it via the supplied HDMI cable using HDMI port, got native resolution right away. 3840x2160@30 Hz.
My only remaining issue right now is that there is some sort of filtering algorithm going on, so the pixels are not being displayed properly. It ruins text, especially in red. Going to update the firmware and see how it looks afterwards. Everything else is perfect.
I've tried both the latest firmware for 39" and 50", no difference. :/ This is the only thing bugging me right now, everything else is perfect.
It feels like jpg compression artifacts.
Edit: Which HDMI input is everyone using? I've been using HDMI 3 all this time. I just tried HDMI 1, and I got no image, saying "Not supported". Investigating...
Picture: Contrast: 55 Brightness: 52 Color: 50 Sharpness: 0 Color Temp: Cool Setup: Noise reduction: off Service Menu -> Others: Backlight: 70 Color Temp: Color Mode: Cool Gain Red: 129 Gain Green: 126 Gain Blue: 122 Offset Red: 503 Offset Green: 510 Offset Blue: 492
Looks like more than just banding on his image. Anyway I am pretty darn sure my 39 inch does not do that but I will verify when I get to work. Excpect another reply in <2 hours. My 50 inch at home:
I don't even notice any banding at all and the color change is very smooth.
lol, your images look banded to me too because my display can't show the smooth gradients.
There is a slight vertical color gradient as well in the image, and I imagine that's why the banding doesn't look like simple vertical lines.
If your 39 doesn't have the problem, I wonder if it could be a linux vs windows/mac thing. Maybe linux is forcing the full 24bit color mode, while windows and mac are handshaking the limited bit range?
