HDMI Multiviewer Switch 4x1 with PIP, PORTTA Quad Multi Viewer Seamless Switcher 4 in 1 Out with Toslink, 3.5mm Audio Output Support 1080p 60Hz, 6 Viewing Modes, Downscaler, Compatible with PS4 Xbox

Absolutely a GREAT product. It's very robust, works as it should, and an EXCELLENT value for what it does.I wanted a 4 input splitter (also with PIP) for busy sports weekends. I have 3 OTA tuners and 1 Ruku device connected. I had purchased and returned 2 other Quad Viewers as they fell short of being practically useful.....simply too many keystrokes with the remote, poor IR connectivity, sluggish response, and several screen modes which made no useful sense whatsoever. They were way too complex to easily use. There was no way the average non-techie family member could or would ever attempt to use them. This brand is straightforward and built by engineers with common sense users in mind.It's very affordable for what it can do, stable, and produces clear, vivid screens. The audio follows the selected screen but can be switched to any screen at any time,.....while viewing any screen. I added a $10 IR repeater so I can place the box inside a cabinet, out of site, and still operate the remote. The repeater extends the range about 15 "reliable" feet.This is a good value. Give it a try, you'll be glad you did.

exactly what I ordered as I expected it - Thanks!

I bought this for PiP (Picture in Picture) capability. I have 3 computers and a FireTV, connected to the same display. I wanted to be able to have a video playing in the corner while I perform maintenance on the computers and monitor server usage. With a KVM switch, I could only connect to one device at a time. This device allows me to do all of that - with the exception that I also have a separate keyboard/mouse switch.Pros:The HDMI Multi-viewer Switch 4x1 allows me to select all four inputs simultaneously, showing a smaller image of all 4 screensA separate Audio selector allows me to select which audio source, all coming in through HDMI from the computer source, to direct to the monitor. I can keep it on the FireTV audio, even if I switch to full-screen display of any computer.I can also scale the video from the sources.The feature/price ratio really favor the price. It’s hard to beat the price.Cons:While you can select two inputs for a side-by-side or over-and-under simultaneous display, it doesn’t remember the previous choices, so a user must modify the settings whenever the device switches from full screen to multi-display mode. The only remedy for me was to put the two most-used inputs in positions 1 and 2, the default locations for 2 input display.The same “have to modify settings every time” issue occurs for over-and-under vs side-by-side. You have to cycle through past over, to get to side, each time you switch from single display to multiple.I can’t use the maximum display resolution. That information was in the description, so it’s not a surprise, just an alert.I wrote more words for Con, but I think the Pros outweigh the Cons, at least for me. I get the functionality I wanted for a low rate, with the extras being the ability to select the audio input, separately from the video input.

Compact, sleek design and easy to use HDMI switch. I like that all the wires connect on the back of the unit. Using this switch to feed two different computer inputs to one television instead of having to use the remote to change inputs.

This thing is pure ass. All I had hooked up to it was Switch 2 and the signal dropped constantly. Don't bother.

This thing works excellent. Swapping between different views is seamless. I've connected three PCs to a large monitor and it works excellent in all modes. I do wish it included a receiver for the remote. Keep in mind that you will need the switch stored out in order to receive remote signal.

I am so happy with this product. It does exactly what I needed. (Split devices between a TV and a monitor) I can play any input on either device or the same thing on both. The separate 3.5mm audio out jacks allow me to also send the audio through my sound switchboard which is the main reason I purchased it to begin with.
