Portta HDMI Video Wall Controller 2x2 4K Multi-Screen Display Processor

Cheap Video Wall Processor With Major Alignment Issues

I wasn’t impressed with this 2x2 video wall processor. You can clearly see the alignment issues in the pictures.

I knew I was taking a chance by buying a cheaper processor instead of a higher-end commercial unit, but unfortunately this one proved the old saying: you get what you pay for. If you need a properly aligned video wall for anything beyond basic testing, I would recommend spending more on a better-quality processor.

Serious lag

I used it for about a month was working fine 2x1 then the top and bottom was not in sync anymore started to notice everything was shifting at different times and side to side from each other could not focus the durability seems good but it’s not working correctly will be returning if I can’t get it fixed

I've had it for quite a while, it's good.

I wanted to wait for a bit to see if it lasts, I've had it for about 5 months, it's a good one. See the picture, 4 75 inch tv's

Worth it despite the lost

Hopefully they won't copyright my display

A firestick will need to be reprogrammed if this is a replacement unit.

Worked like a charm! If this is a replacement and you were using a firestick you will have to reprogram the firestick on the screens as well. Easy!

Edge masking issue

It works very well, seems like good quality, very easy to use with remote, but huge flow on the edge masking. Not sure if it's with my TVs or devices tested. But can't get it fixed. Up and down TVs don't have an issue, but side to side cuts out too much of the image, becomes too noticeable.

It's 4x TLC fire TV, and I tried a windows PC, Chromebook and Chromecast. I'm Chromecast the edge masking was the least bad, fairly noticable with Chromebook and not much better on Windows PC

Perfect for screen splitting

Works great for the 4 split screen tv set up I put in my son’s room. Cheap alternative to the several hundred door set ups so the average family of 7 can afford nice things

Awesome product

Very good product for the money. I used it right now for a 1 x 2 side by side configuration and it works great. It would have got 5 stars but it pixelates (About every 30 mins) for about 10 secs. Not bad at all and still worth the money.

BEST PRODUCT

I was initially unsure about this brand, but the price fit my budget, so I decided to give it a try. The product arrived on time and in perfect condition, and what I appreciated most was how easy it was to use—no complicated setup, just plug and play. I would highly recommend it!

Cheap = garbage

This is garbage. Top to bottom. Side to side. Just a waste of money.
