Review: Did the job I purchased it for 👍 Fast delivery, more than happy 😃
Review: We tried several other video multiplayer’s and this was the only one we found that could work without connecting to/through computer. Easy to connect and allows you to rotate picture especially since the TCL’s we bought didn’t have that capability. Once installed set to 2X2 and changed the orientation of the top 2 TVs and voila we had a video wall where we can watch 1,2,3 or 4 different shows. Can’t wait for football season!! Was able to connect surround sound to receiver to tv and 4 (cable, Firestick, PS5) inputs to D-Tech digital box for easy connection to shows we want to see. Pricey but it was exactly what we needed to create our home theater. Highly recommend for anyone wanting to do the same.
