4K60 UHD Video Wall Controller 2x2 1x2 2x1 1x3 3x1 1x4 4x1 TV Wall Controller for 4 TV Splicing Display Support 3840x2160@60Hz Inputs and Rotate 90 Degree for Portrait Mode Screens

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.

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

As stated by other users the remote does not communicate with the unit. Doesn't power on/off, switch inputs etc - nothing. Checked batteries, swapped with new ones and still no dice. Seller - can you please let us know how to get a working remote? As a result the unit has to stay on 24/7 and it’s pretty loud bc of its internal fan. Happy to change my review to 5 stars once this issue is resolved. Update: Seller was quick to respond and sent a new remote and was super helpful so changed to 5 stars.

This is my THIRD time buying this product, and all THREE times I’ve been forced to return it because it's defective. Both the manufacturer who makes this absolute garbage and Amazon for allowing it to be sold on their platform need to wake up. This is completely unacceptable. Unbelievable. Three attempts, three consecutive returns. This time, the device doesn't even power on. It is dead on arrival.

During a recent renovation I installed a 4 tv video wall to watch several different games at once. The first device cost over $1k and couldn't do what I needed. This product is half the cost and functions perfectly. I installed 1 firestick and plugged hdmi into each of the tvs and (has soundbar input) and I can watch one game or 4 different. Love this product!

The only one I found which does rotate the screen to 90 degree. I bought couple of other boxes prior to this, some which were double the cost of this, but they didn't perform or rotated the screen to 90 degree even though their website description mention that they do. This one works prefect and very easy to setup.

My 1st DIY video wall is now complete. I probably watched a week's worth of YouTube reviews before deciding on this controller. So far I have not been disappointed. I mounted my top screens upside down and the controller was able to flip the video as needed. My controller has a DPI port on it. Initially I thought the port was bad but after reaching out to the vendor they told me that I needed a HDMI->DP cable/adapter. As you can see from the picture I'm now sourcing multiple inputs. If there is something better or cheaper out there I'm not aware of it, but this product gets the job done.

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!

I is east to sed up.
