Some 4K monitors may work with your Mac, but others may not. In OSX, there's a hard-coded pixel clock limit of 165 MHz, but the Seiki firmware runs at 297 MHz. Find out what your 4K monitor runs at; you can search the internet for "mac 165 pixel clock limit" to learn more.
Hence, the Seiki did not work for my Late 2014 Mac Mini as I had hoped. But using this activate adapter worked perfectly!
After connecting your 4K monitor, it may be necessary to reset NVRAM. Just shut down, then hold Option+Cmd+P+R during startup, after you hear the startup chime the SECOND time, immediately release the keys. Go to System Preferences > Displays and select the lowest refresh rate. After the screen comes back, you should see some 4K resolution options to select, including 3840x2160. Select it, then set your refresh rate to 30 Hz which is the highest supported one for 4K on a Mac right now.
Are your fonts jagged? I had to turn the "Sharpness" setting to 0 for my Seiki. This made all the difference, and everything is perfect now.
I have validated that indeed, THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG
For those of you wondering, the Accell adapter is using the BizLink chipset (Accell is owned by BizLink) and the Club3D version is identical to this one, Club3D just rebrands the device.
I just got this hooked up to my Seiki 39" 4k Seiki SE39UY04 39-Inch 4K Ultra HD 120Hz LED TV (Discontinued) to use as a monitor with my Early 2015 13-inch Retina Macbook Pro and the 4k is looking great. I was banging my head against the wall when I first got the TV trying to get my computer to recognize 4k, and the Acvtive DisplayPort adapter did the trick.
Polybag packaging was as expected, and there are some product stats on a sticker on the bag. I was able to plug the adapter into my computer, plug the HDMI cable into the adapter, and the monitor immediately recognized the connection. I am able to access the retina monitor settings running OS X El Capitan without any issues or third party software needed.
May update in a couple of weeks to see that all is still working well.
Every once in a while, you come across a product that just works. This is one of them.
