NIERBO HDMI Quad Multi-Viewer - 4 in 1 Out HDMI Switcher, 1080P, Seamless IR Control, 3D Support, 5 Modes for PC/STB/DVD

Works well with multiple HDMI inputs. College football can be seen on ESPN, CBS, FOX, ESPN2. I use two rokus and two firesticks, all streaming at the same time. The audio may move a little slow when switching devices, but not that much. Just 2 secs off. Changing the format allows you to watch a movie, and three games on the side. I enjoy it and it is well worth the money. Since the TV manufactures want to charge an arm and leg for PIP and P&P, this is a better alternative. If the switcher goes bad, just buy another one. If the TV goes bad, we have a big problem. Happy here!

Product works great does exactly what it should

It does everything promised and I’m happy with it but it does need a better remote (range is very short and you have to point directly at the receiver). Also, when you go from screen to screen when in 4x view, the audio is not instantaneous (but it is short, about 1 second). You can’t switch audio directly to any one ‘screen’, you have to step sequentially through screens 1 through 4, and then a no audio step to go completely around. So to get audio from screen 2 if you are presently on screen 3 you need to do 4 clicks and then wait 1 more second for the audio to come on.

Does the job OK but you cannot power off. Once plugged in it is powered ON all the time regardless of input. Remote is slow and must be in close proximity and has no ON / OFF function. I paid a little more thinking I would get a better product but alas it is same old imported quality.

We love this Nierbo HDMI 4x1 Quad Multi-Viewer. I mention the name b/c some reviewers complained about seeing the resolution pop up when they changed channels. My model shows only CH1, CH2, etc. It disappears within 2 seconds. Maybe my model is different. It's a great product for the price (compare to Crossbow to see the difference). I'd buy it again in a heartbeat.PROs: You can cycle thru multiple viewing modes (as advertised - I've tried them all), use a single button to split the screen into 4 quadrants, select any channel to go to full screen for that channel, and the image is not degraded. Also, Nierbo's customer service is terrific. I installed the original switch, noticed that CH3 did not work properly, got a response to my Sunday afternoon email THAT NIGHT, exchanged a few more emails and 5 days after my first email I had a replacement that works perfectly. Nierbo had included their service email address in the product's box so I contacted them direct. I did not go thru Amazon.CONs: It takes a little time to figure out the "Mode" and "HDMI 4x1 Quad Multi-viewer" (yes, all of that verbiage is on one button) buttons. But we usually just use the single button to split the screen into 4 quadrants then select the channel we want from there.BTW, we have 2 TiVo Premieres, a TiVo Stream 4K and a Blu-Ray player plugged into the four input ports that output to to a 55" Smart Samsung TV (not 4K). This switch does not support 4K.

This is incredible. I never thought I needed something like this; I can have my Firestick TV screen on one side while my PC screen on the other or change it to another mode where one screen is larger than the rest, switch to another channel to enlarge while the rest are small or as you see in my pic, yeah.Seriously, this thing is incredible! Money well spent! Sorry if I sound like I'm shilling but I am just extremely satisfied. Definitely will buy another for the living room 50 inch tv (Mine is 32 inch).The only problem I have is the first port is static at first but I have to unplug the HDMI cable and then reinsert it and it fixes the problem. A hassle but yeah. I did say money well spent but I would rather get this at a low price if this is a common problem 👍

i like the cost for what it is, other products capable of a 4 split 60hz are almost twice as costly,i would have liked and over under 2 split setting, but beggars cant be choosers.

This HDMI switcher 4x1 by Nierbo works but it has a very short range and an unreliable remote control. I have to be exactly in front of the unit for the remote control to work. It also has a tendency to not work when you have a few HDMI lines hooked up then when you add more it will not work. I had to power off the unit a couple times to reset. The other annoying thing about this unit is that on the upper left corner it always display the "1920x1080p" that I cannot remove. I emailed to the manufacturer about this and they said it cannot be removed. This annoying display will always display when you switch from one source to the other. It will disappear after 2 seconds though. But even that, do you want your livestream audience to see that on the left corner every time you switch? It is a little unprofessional don't you think? Because of that, I am returning this product.There are some good things about his product too. I bought this item because it advertised it has seamless switching between 4 different sources with no black screen delay in between. That indeed is true. It is truly seamless switching between different sources. The only downside to this is the remote control and the power on/power off when you connect more input sources, and of course, the "1920x1080p" on the upper left corner of the display. If you don't mine those things then buy this product. For my purpose I needed something a little more professional since I use it for livestreaming and live presentation that need to switch between multiple inputs to one output into the projector. I hope this review helps.
