What is the refresh rate at 4k resolution?

With DisplayPort 1.2 it will be 60hz. DP 1.2 allows Multi-Stream Transport (MST) support which translates to this monitor being recognized as two 1920x2160 monitors each at 30hz. If you go the HDMI 1.4 route you will need a card with two hdmi outs for pretty much the very same reason. A single HMDI will only give you 30hz.

The maximum resolution on this is 1080p, contrary to the little blurb that they have on the product page. I bought this solely because I hoped to connect my gaming PC (which has Mini DisplayPort 1.2 which can support full 4k at 60hz) to my 4k TV (Which has HDMI 2.0). Through this adapter my PC can only see my TV as a 1080p display.

I don't believe the refresh rate is that fast. More like 30 seconds. It is accurate within 4 pounds or so and very repeatable.

Sort of but you will not like it. Windows does not scale to those resolutions (tiny type and icons, programs may not display correctly, e.g Photoshop which also does not scale reliably on this Retina notebook I am typing on). Nothing short of a top of the line video card (e.g. Nvidia 780) can support adequate frame rates to avoid "tearing" and other motion artifacts during display refresh according to reviews. My reading leads me to believe that no single video card (unless it had two GPUs soldered together) can support frame rates for gaming at these resolutions. I am not sure if 4k video, presuming you have a source, will display satisfactorily via computer except with highest end video cards because they just can't redraw the screen at 60 fps. Scaling and motion artifact problems are a major pain in every day use: ask someone running Windows on a retina display (personal experience). IMHO monitors like the Dell Ultrasharp with higher than 1080p resolution, 8 bit IPS panels and large gamuts are more desirable than 4k for most hi end users and the 760 will support that resolution well for all practical uses. If you want to do 4k video production you have to spend accordingly for computer gear. I do not think the market or technology is quite there for consumer 4k and it is not clear if demand will drive down prices or get Microsoft and Apple to amend their OSes.

Considering that HDMI 1.4 can only do 4k@30hz (so 30 frames per second), I'm not sure how the this translates to the actual panel being capable of 120hz unless they are referring to lesser resolutions. HDMI 2.0 is supposed to support 4k@60hz. I am interested in 4k/8k resolutions primarily for PC. Displayport supports 4k@60hz but typically it's used for the PC market.

I'm running 4 @ 1920x1080 and all are 24 inches and up with very few issues. Make sure your power supply is at the upper end of the spectrum, I have to unplug my monitors when I reboot which is a little irritating, but it seems related to the power supply and nothing else. Also pay close attention to the listed issues with DVI / HTMI / Display Port.

The refresh rate (Hz) can vary from 50 Hz to 75 Hz depending on screen resolution. For a list of the refresh rates and corresponding resolutions, click on the following link:

Most modern cards will support 4k for video playback. Nobody can tell you what framerate you will get without knowing which game you are playing. They are all different. Many of the hardware websites like Toms Hardware, HardOCP and AnandTech have done reviews of this card where they run it at 1440P and 4k resolutions. I run some games at 7680x1440 across 3 monitors and can play well above 30fps. Your mileage may vary.

make sure you set the refresh rate to 144 through whatever control panel you have for graphics (Nvidia or AMD) If you don't have drivers, then get them

If you are referring to the refresh rate, this set is above average at 240hz. I looked at it a brick & mortar retailer before buying on Amazon

If you have 120Hz, you shouldn't have a problem. Were you not able to watch in 1080p ? I don't know anything about changing refresh rates.

240 hz refreshes much faster than 120 so better for action or sports. No one is broadcasting in 4K maybe in the future but for now save your money.

um im not sure what you mean by refresh rate. like how fast it turn on? pretty quick. be a little more pacific maybe i can answer your question

I have done exactly that and it seems to work well at 4K, although I'm using it primarily as a monitor, not to watch TV. So I don't know about the frame rate.

pretty good - set it to 640x480 and 'high quality' in &lt;monitor settings&gt; for best quality

As the others have noted, the box states 60HZ. I can say that I've run much hi-def content, with no discernible motion blur above and beyond what you'd typically expect from an LCD screen. I haven't gamed however, but I've had the monitor since September of 2012 and it's been rock solid for my purposes.
