MT-VIKI 4K 2x2 Video Wall Controller, HDMI TV Wall 2x2, Support 4K@30Hz Input & Output, 8 Display Mode 1x2/1x3/1x4...

This is AMAZING!!!! I tried COUNTLESS adapters, GPU's, fiber HDMI, RP/HDMI converter etc. This is TRUE 4x on each monitor/TV and YES it's 60 hz. This solves it ALL. It's all way less stressful on the system vs running 4 screens all off one 3080ti. Now it's just one into this box and this hardware box does it all. and it does it... perfectly!!!

It works fine. You need to play around with the resolutions to display on certain formats but it does the job well. I recommend it.

Had this for a couple of months now works great out the box. This is not a scaler make sure your settings our correct on your laptop when using other wise you will be frustrated. Make sure your modes are correct on your tv settings as will if it does not fit proper out the box. Make sure you have good 4k hdmi cables coming into the box. I do like that it rotates make sure you mark your cables you know which input it goes back to once installed if you have to unplug. Will buy another as a back up.

No lag delay. This was able to allow me to “daisy chain” 3 85” lcd displays in vertical aspect in order to create a non seamless large format display in my living room. The video quality is excellent and never has any issues. The remote is easy to use, but lacks a power button for turning the device on or off. It must be manually switched on or off on the physical unit

Rating: ★★★☆☆The video wall controller is just okay. It did a good job of sending the matrix feed to all 4 TVs, and the setup was fairly straightforward even though the instructions were extremely lacking. However, I ran into a major issue with adjusting the bezel settings both horizontally and vertically—the picture wouldn’t align correctly across the screens, which was pretty frustrating. I tried multiple configurations, but none worked perfectly. If you’re looking for precise alignment, this controller may not be the best option. But if you just need something that reliably sends the feed to multiple screens, it gets the job done.Return the item for a different manufacturer. Much happier with the new product.

Love it!! Simple set up and very easy to use.

Very easy to use but for some reason you can’t adjust the bezel. Controller has the buttons to do so but it doesn’t do anything. Does anyone have any idea how to fix it?

What a cool idea for the grandkids room being able to use 4 monitors setup in a 2x2 configuration. I hooked this up to their Xbox so that they could have a nice big screen to play their games on. This thing is super functional with the ability for different layout configurations based on your use case. This was incredible easy to set up and comes with a remote control to use for all of the functions. It was much smaller than I anticipated but don't let that fool yah it is built very well and does the job with no issues. Picture quality on 4 - 32 inch FHD monitors was very good and didn't see any issues while they were playing. There is 5 HDMI ports 1 in and 4 out making it super easy to setup. Great video wall controller!
