You probably do not have HDMI 2.0 which is required for 60hz.

What has hdmi 2.0 installed, the video card? or is it a type of cable? Forgive my ignorance, I am new to this stuff.

Video card and technically the cable too, but the vast majority of cables support it. Not many video cards have native HDMI 2.0. Check your model of video card on NewEgg and see if it has 1.4 (which I am sure it does).

Edit:

I had the HDMI plugged into the wrong port, the writing is so small on this TV. GOT IT WORKING WOOT. Thanks mate.

Hello,

I recently picked up a SE42UM for cheap and was testing it out on my PC and I cannot get the TV to display 4k@60hz. 30hz works fine, but 60hz is green/pink image that is cutoff. I have an MSI GTX970 and tried 3 different high speed HDMI cables on the side port. Any idea what I'm doing wrong?

Thanks!

Are there any UK users here? I've just bought the UK version of this TV and I'm so scared it's going to be too laggy to use and that the firmware update will not work for it. The TV is here:

http://www.ebuyer.com/719882-seiki-se42ua01uk-42-ultra-hd-4k-led-tv-se42ua01uk

If anyone knows anyone who has modded the firmware or even where to begin, I might be able to work with my friend to alter the firmware to be accepted by the UK model that I have. I will not be using this TV as a TV at all and only hope to use it as a PC monitor, therefor the lag issue is going to be an absolute deal breaker!

Thank you so much to anyone, in advance, who responds or helps out in any way, shape, or form.

It looks like there isn't a firmware update for the UK version. When was that model released? It might just have the newest firmware already, as Seiki said they wouldn't do further updates for the SE42UM when I contacted them a while back. If it has a PC mode, you're pretty much set I think. See if you can follow my setup guide, and then if you still have issues it might be worth looking in to creating a modded firmware. Here's the link to the SE42UM's firmware: https://onedrive.live.com/redir?resid=9EC20EC148C073D7!851023&authkey=!ADgqAhYvYsKO3wo&ithint=file%2cbin
As for how you'd go about modding it, I have no idea. Careful you don't brick your TV since there's no stock firmware available for download!

Also, in regards to the lag, if you follow my guide successfully, you'll get about 50ms lag total. To put it in perspective, the QNIX QX2710 (a popular 1440p korean monitor) has 22-33ms lag, and not many people that own one even mention it. As I said in my review, it only matters if you need per-frame accuracy (CS:GO, LOL, etc), at which point you're looking at the wrong type of display altogether. I'm at the point where I can't even notice the lag with regular usage now. TBH, if you are getting "lag," it's probably a result of having a poor mouse and not because of the actual lag of the display. 4k+42"+crappy mouse=ugh. It'll just feel wrong moving your mouse around, dragging windows, precision clicking (eg small buttons), and so on. Irregardless of the model/brand you have, if you have a 4k screen of this size or larger, you'll want a gaming mouse just so you can traverse the display smoothly and quickly. One case where you won't need a great mouse is if you love super low mouse sensitivity and have a LARGE mousepad.

Nice lag chart:
25ms - pro gamers will notice if you A/B a 8ms with a 25ms monitor, but it probably wouldn't bug them too much overall. On it's own, a 25ms monitor probably would only bother INSANELY sensitive gamers, and they might not even be able to say with certainty it's the display's fault.
50ms - sensitive gamers would pick up a subtle difference between a 50ms and a 8ms monitor, and many standard computer users wouldn't be able to tell a difference at all. The standard users that can notice it probably wouldn't notice it until you deliberately point it out ("does it feel like it has any lag?").
75ms - many people will start to notice something is slightly off, the comment would be "things don't feel as snappy, not quite sure why"
100ms - Pretty much everyone will notice at this point, and then you'll start hearing "this TV has lag."
>125ms - display gets a reputation for having bad lag. This is where the SE42UM sat for a while. The lag was so bad, it scared people away from ever trusting that "most of the lag is gone" means it's hard to notice the lag.
TL;DR: Lag won't be a problem for you unless you're one of those people who needs a 8ms lag monitor at 120hz/144hz. Depending how sensitive you are, you might be able to feel a slight difference between the SE42UM and your normal monitors if you deliberately look for it.

Also, just played Overwatch for the first time on this today and had a great time. Second game I ended up getting play of the game, yay! Yes, at 50ms this thing is suitable for heavy FPS gaming (but is your GPU? lol), which should say a lot. TBH, my biggest problem with FPS games on this monitor is that my GPU doesn't get over 60fps at 4k with graphics settings at Ultra. Typically I need to turn things down to High instead.

Wow, thanks for your comprehensive run down. Turns out that you are right and there's no firmware but that things already seem fine without it. I don't get any kind of "PC" mode or "gaming mode" and I'm wondering if I should move to HDMI port 1 or 2, as I'm currently in port 4, but things seem great. Had a problem with the screen forcing an aspect ratio when I switched down to 1080p for a game that there is no point utilising 4k in (that will be 2 of 3 games I regularly play in all honesty) which caused the screen to zoom in, but that has been resolved. One issue is that I cannot alter sharpness in 4k at 30hz, but I can when using 1080p at 60hz. Possibly cable related? All in all, I'm happy, and can barely notice any input lag at all.

I've now tried 5 different cables, the last one came with a 4k ASUS display. I'm still can't get the TV to do 4k @ 60hz right. I am using the 2.0 port on the TV. Any ideas?
