Everything else is identical

RickDude, I disagree that the SE42UM is HDCP 2.2 compliant on any ports. I bought a Roku 4 and could not get it to display 4k at all. It showed HDCP not compliant error on port 3 which is marked HDMI 2.0.

I did further research and found a SE42UM product sheet which clearly states all ports are HDCP 1.4 only.

Needless to say, I returned the Roku 4. At least it works as a decent 4K monitor. Yes even for light gaming like World of Warcraft (with the mouse lag patch).

If anybody knows of a work around for the HDCP 2.2 on this model. I would love to know about it.

I just picked up the Seiki SE42UMS to run as a monitor off my surface pro 4. I have run through this thread--and similar others elsewhere--and still can't figure out how to pull 4k@60hz out of this monitor. My graphics card is the Iris 540. All information floating around says I should be able to get the full 60hz but i can only achieve 30hz. I have the proper HDMI cables, the DP1.2 to HDMI2.0 4k@60hz adapter.

I'm fairly new to Windows 10 so I am hoping the wiser minds here might steer to me to a setting I overlooked. When I go into the display settings menu and Display Adapter Properties, my sole choice for 4k is 30hz. Any ideas? Thanks so much guys!

@matterino I could be wrong but I recall reading dp1.3 was required for 60hz...plus all dp to hdmi adapters I looked at a few months ago never did actually advertise hdmi 2.0 supporting a 60hz refresh rate, heck most didn't even acknowledge the hdmi version spec at all.

Ok, I did find that dp1.2 does support 4k @ 60hz but the conversion is the problem and found another thread that explains dp1.3 is required to convert to hdmi 2.0 and support 60hz.

Ah so the adapter I purchased that converts DP to HDMI 2.0 for 4k@60hz requires DP1.3 as a pre-req? That's good to know! So essentially with the Surface Pro 4 I would be limited to using a monitor that supports display port in order to attain 60hz. Bummed I can't use this monitor, but glad to have an answer.

Thanks pingram for the quick response! I would have been scratching my head and digging through internet garbage for days without this little detail.

Active DP1.2-to-HDMI2.0 adapters don't seem to be mature yet, and may show problems. DP1.2 port requires such active adapter to support 4K@60Hz 444. DP1.3 port requires just a passive HDMI2.0 adapter, since it natively supports HDMI2.0 as an output mode when requested by the TV, but such passive adapters aren't sold yet.

I purchased one of these active adapters you speak of from UpTab: http://www.uptab.com/minidisplayport-thunderbolt-to-hdmi-4kat60hz-adapter-cable-gold-plated.html

The product information gives the impression that it will produce 4k@60hz from a mini displayport 1.2 to hdmi 2.0. But it seems from the previous posts from those smarter than me that there is more to the story here.

Perhaps it is the relative immaturity of these products mentioned above that is giving me issues. Or the very real possibility I am screwing something up on my end. Whether I am wrong or right, I at least would like the info out there to save someone else the hassle.

Does anyone know how to get this tv to turn on when my computer auto turns off the display without having to power it on with the remote?

Anyone else experiencing this? I have the SE42UM, I'm trying to use it as a monitor, and even with the updated firmware, photos and video look like it was passed through a watercolor filter. I thought it might be a Windows 10/GTX760 combo issue, but the Macs I've tried have had the same problem. I tried different HDMI cables, made no difference. Text is ok, and when used as a TV it doesn't seem to have this problem. But when hooked up to my PC at native resolution 60 Hz, any images or video all look like low res watercolor versions of themselves. Seems to be some sort of native image processing that I can't turn off.

Also, BabylonDown, I haven't found a way to get around the auto-shutoff.

Sounds like you are seeing 4:2:2 which is all this set is able to display.

I've had no such issues with my SE42UM and I have it hooked up to my computer via HDMI.
