Geniatech ATV1660K TV Box Supports Dual HDMI Output, HDMI Input

There are many applications that may benefit from dual display support from digital signage to healthcare to retail or entertainment either to provide access to two different output for the service provider and customer or simply to mirror content.  Most Android TV boxes only come with one display output however, so in most cases, you’d have to switch to an Intel mini PC or add a USB-C display adapter if supported by the hardware.

Geniatech ATV1660K TV box supports dual HDMI output out of the box, as well as HDMI input. The Android 5.1 TV box is powered by the time-tested Rockchip RK3288 processor and comes with 2GB RAM and 16GB storage by default.

Android TV Box Dual HDMI Output

Geniatech ATV1660K runs a fairly ancient Android 5.1 operating system, and ships with AV and HDMI cables, a power adapter, an optional RF remote control, and a user manual.

While both outputs are HDMI 2.0 ports, the system can only support 4K UHD on one of the port, while the other can output up to 1080p “Full HD”.  Also note that Rockchip RK3288 is one of the first 4K processor, so it had some limitations meaning on some TVs output would be limited to 4K @ 30 Hz. Also note that H.265 and VP9 video codecs are not supports, and the system can only play back 4K H.264 videos up to 24 fps. [Update: RK3288 also supports 10-bit H.265 contrary to what’s listed on Geniatech product brief]

The company also did a poor job at explaining the purpose of the HDMI input port, as in they did not explain the purpose at all. But I can only assume it’s made to connect an input device and overlay data over the video output using Geniatech SDK.

You may want to visit the product page for a few more details, and if interested, you can purchase the device on Geniatech store for $139, or request a volume quote.

  1. Can it display independent video sources on the two displays, or is it just cloning the primary display on the secondary display?

    1. Based on the information and illustration, I understand it should be independent displays, or that would be quite misleading. Something like a user interface on one display, and a video on the other. Playing two videos at 1080p60 would not be possible, except while using HDMI input for one of the sources. That’s the way I understand it should work.

      1. Yeah, that’s kind of what I expected. But as you say, that image is a bit misleading, hence the question.

      2. Independent displays work on RK3288 (obviously the 2nd HDMI must be behind a converter for LVDS/eDP/whatever) but no idea about video. On YT when searching for ‘RK3288 dual display’ I found only Firefly demos with video on mirrored displays.

  2. The rk3288 has 10bit h.265 video decode. It was one thing I loved about my old beelink android tv box.

    1. Thanks for the correction. I should not have trusted what I read in Geniatech’s product brief.

  3. How is this company still around? Who is buying their stuff?

    I still can’t find the ATV1950? Do they only sell B2B digital signage or something?

  4. What I do not understand is how anyone can post the advantages of a dual hdmi output tv box when it is not maximally functional and everything else about the box centers around old technology and hardware. Probably stacks of unsold stock trying to get of the shelf in the face of much better products
