Review of Patuoxun Multimedia Dock (HDMI, 2xUSB) (Note II, S3, S4)
I recently purchased a Patuoxun Multimedia Dock advertised to be compatible with the Note II, S3, and S4. Please see the bottom of the post for product information.
I am quite happy to report that this $24 dock functions almost exactly as I expected. I have only seen videos of the Samsung Multimedia dock, but from what I can tell this off-brand dock works nearly the same. USB ports and HDMI output can be used simultaneously. For example, I can watch Netflix on the big screen and control the phone with a mouse at the same time.
The two USB ports can be used for standard mice, keyboards, USB drives, SD card readers, and unpowered generic USB hubs. Just for fun, I chained three USB hubs together, plugged in a mouse, and it worked flawlessly. (Not sure if this proves anything, but I thought it was cool.) I have read that NTFS drives are usable after the installation of a special kernel or driver.
However, there are a few points worth mentioning. There is ever-so-slight, but perceptible HDMI lag. (My standalone MHL adapter exhibits this behavior, too.) Mice and keyboards are definitely usable, but you can tell the lag is there. I have a few hypotheses: 1. Perhaps the dock indeed lags some. 2. Perhaps my ROM/Kernel/whatever is a part of it. 3. Perhaps a bit of both.
Also, when a USB mouse is plugged in, HDMI output auto-rotates to landscape, the phone screen turns off, and roughly ~1/2s of HDMI lag occurs (presumably due to a software bug that occurs when a USB mouse is used). Many threads say this happens with the official Samsung dock also. This issue does not occur with ShareKM (due to the nature of the app), and others report that Bluetooth mice do not suffer the 1/2s of lag.
If anyone knows of a solution to the HDMI lag and USB mouse lag issues, I'd love to hear them.
I'll do my best to respond to questions about the dock if anyone has them.
****PRODUCT INFORMATION / DESCRIPTION****
I don't think I'm allowed to post links, so here's the info. Search the product description in Google. I purchased my from eBay as described below:

I'm assuming this is the same product, since it looks identical to mine:
