4ch UHD Video Wall Controller

I left a 2 star review for this seller and would like to retract it. This seller is reputable and offers a great product and service!

The first one I received was bad and didn't show any video output thru any tvs. However a 2nd unit was sent and now my 4 tv setup works. In vertical position. Small tips for setting up. Mess with the settings first to get it to where u need. Exit from the menu. Then use the inputs buttons on the remote to change orientation if needed. For example Make note that a 1x4 is not the same as 4x1. Also there is a processing lag. Not recommended for anything that requires precision for example like playing action videogames such as call of duty or any fps for that matter

I used this with four Samsung 65” Smart TVs. Once I got all 4 mounted and plugged in all the HDMI’s and powered everything on it instantly was on all 4 screens. I didn’t have to touch nothing!! I didn’t have to turn any of the TVs upside or adjust anything. It was instant plug & play for me. I’ll read the manual later on to become familiar with it but since it worked as I wanted it INSTANTLY straight out the box I don’t wanna touch it lol.

I is east to sed up.

Using in a 2x2 config with 4 55" Samsung QLEDs, and generally impresses family and visitors. PIP functionality works great. Running 3 different streaming sticks through receiver to ISEEVY box works well, solving the audio issue (except for PIP). 2 minor complaints: This box does not seem to support HDCP 2.2. 4k content is restricted to 1080P due to HDCP issues. If I bypass the ISEEVY box and connect directly from receiver to TV, HDCP issues are resolved and 4k content is passed through. Watching fast action content (live sports), lag between screens is noticed sometimes as if each output stream is updated serially in a round-robin fashion Update: HDCP issue can be resolved using a splitter -- https://www.amazon.com/gp/product/B08D9BCX1R/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
