Can I run the full 4K 3840 x 2160 resolution in 60hz or 120hz from a PC graphics card over HDMI port? Are there any DVI or DisplayPort on this TV?

No it works with the Onkyo TX-NR636, Yamaha RX-V677 & Pioneer VSX-1124-K @ 2160p/30Hz

No. Max theoretical rate of HDMI 1.4 is 30Hz. Best most of us have seen is 18Hz. DVI & HDMI are interchangeable; I use a Mini DisplayPort to HDMI active adapter from my Macbook Air to the TCL 4K.

Yes, the refresh rate applies to the screen display, not what signals are coming to the tv via the HDMI cable. The HDMI is the only way to go. You must use HDMI to get full 1080 HD resolution. The other types of cabling gives you 720 or 480 depending upon the cable connection you use. The 3 types of connections require 3 different cable sets. Of course you must have a HD tv to get full HD, but it would be a shame to have a 1080 HD tv and not get the full resolution by cabling the tv wrong.

I am currently running this monitor on Mavericks at 60 Hz with full 4K resolution. There is scaling available in system preferences.

I have the same problem, same tv, same dvi to hdmi adapter, etc...Except I've got an ATI Radeon 8500.I wonder if it's an issue with the tv input and not the video card? Did you ever find a resolution?

http://www.displayport.org/cables/how-to-choose-a-displayport-cable-and-not-get-a-bad-one/ From what I have read, all DP cables should support 4k @ 60Hz and other DP standards.

As others have stated, it only officially supports 1920x1080 via HDMI. I managed to get it to a full 2560x1440, but I had to create a custom resolution and I could only get it to 30fps. Not ideal, but it's acceptable for me. See my image and review for more info.

Over digital media (HDMI or DVI) this card is capable of supporting up to 4096 X 2160. Ultra high resolution usually means 4K which is 3840 X 2160. So I would say this card could certainly support the resolution. Whether you will want to run games at that resolution is another question. Most don't even support it yet. But short answer is yes.

From the manufacturer's page: "3840x2160 at 30Hz or 4096x2160 at 24Hz supported over HDMI. 4096x2160 (including 3840x2160) at 60Hz supported over Displayport. Support for 4k tiled MST displays requires 326.19 driver or later." So, yes I believe so.

Yes. Additionally, the card is 4K Ready using DisplayPort 1.2 (4096X2160). You must use HDMI 1.4a (4096X3112) to get to the 4K and if you just want to use DVI (as a backup for example) it will drive your monitor at 2560X1600. Hope this helps.

I have a GTX 670 and the hdmi works for full resolution and sound. I've read the display port gives full resolution chat i Don't know about sound

Was only able to go up 1080P@60hz by default ... I am using a gtx 670 for the test.I did a custom resolution through nv control panel and it actually go up to 2560x1440 but it didn't look good at all. DVI and DisplayPort seem to have no issues with it.

my PC nvidia display card has a display port ---my monitor has HDMI -- it works flawlessly and i don't need an adapter

I used a DVI to HDMI cable and I am getting 1080p.If you video card supports it, you will get 1080p.If you use the vga connector, than maybe 720p is the max?

The reality is tricky. The ports are HDMI 2.0, but only in that they support 4:2:0 chroma subsampling. The display itself is only capable of 4:4:0 (which isn't a valid HDMI subsampling mode), so the higher bandwidth mode of HDMI2 is not actually used (or supported) and you're stuck with half-resolution chroma (in both X and Y) with your 4k luminance. That's fine for games and movies, but bad for sharp, colored text and drawings.

They might be able to at lower refresh rates, but display port is generally better at that high of resolutions. The highest dvi supports at 60 hz is 1920x1200.

Yes, to get full resolution on this display, you want to use Dual-link DVI or the display port. The HDMI port is only 1080, but... it will still look good on this display because it also displays a native 1080p resolution automatically

I read somewhere that, it supports a resolution of 2560x1600. so it should support dual monitors if the total resolutions falls under this. I'm using nVidia GPU, so I never tried the onboard hdmi or DVI.
