Review: Great picture quality. User interface could be improved. - Great picture quality. I don't find the user interface for switching between Multiview modes as intuitive as my other older unit. Review: I have four older computers that I need to keep running at all times, each with its own separate monitor, keyboard and mouse. This is quite messy and takes up a lot of space. My wife surprised me with a G9 widescreen monitor for Christmas. This freed up my original 42" 4K monitor. Instead of shelving it, why not employ it to display all four older computers at the same time since 4K resolution is exactly four times the dimensions of standard HD resolution (1920x1080). Unfortunately, my 4K monitor only has PiP for two inputs, but I needed four. Not wanting to let a perfectly good, high quality 4K monitor go to waste, I looked around everywhere for a 4-port PiP matrix switch. The OREI 4K Multi HDMI Viewer Quad 4 in 1 Out Switcher was the perfect solution, and well under the cost of some "professional" models. Setup was super easy. I connected all four monitor HDMI cables (of various quality levels) to the switcher, and connected the switcher to the 4K monitor via one high quality HDMI cable. Note, as I found out later, cable quality matters, so try to use four input cables of decent quality and of the same brand/model. Using different cables will display different quality outputs. Use the best HDMI cable you have for output. From the front panel, I toggled through options until quad-mode activated. Suddenly, all four computers showed up on the screen, each on in their individual corner, all in 1920x1080 (60Hz) resolution, and including sound from each computer. With all four computer connected to one monitor via the switch, I wondered if it could also act as a KVM so I could control each computer with just one set of keyboard/mouse. Unfortunately, this switcher does not act as a KVM - it only combines multiple video/sound inputs into one output. Instead of buying a separate KVM, I set up special (free to use) software on all four computers. The newest computer was designated as "master", and the other three computer set to be clients. This allowed the use of just one set of keyboard/mouse on one computer to control all the others. It was cinch to set up, and works perfectly! Saved a few hundred bucks not having to purchase a KVM. My desk looks so much cleaner now, with reduced cabling and just one set of monitor/keyboard/mouse where there used to be four sets. Quality is exactly as expected. I am very pleased with this purchase. I gave this product 5 stars, and it is well deserved. Everything works exactly as advertised. Some random observations: +Get the best cables possible. There is visible difference when using lesser quality cables. This product does not reduce video quality, but using cheaper cables will definitely degrade output. If in doubt, use four cables from the same manufacturer for the video inputs. Use the highest quality HDMI cable you have for the video output (rated at 4K 60Hz minimum). +Do not lose the remote control or manual! Using chassis buttons is clumsy. Using the remote brings up a nice menu with many features, all well organized on the screen. +Some screen modes stretch or compress the picture in order to fit the selected picture box. I tried changing the computer's output settings, but none of my computers had dedicated graphics cards and could not scale to the matching dimensions. This made some modes visually unusable due to stretching and/or squeezing. +As noted above, this device will scale video inputs to match the selected output dimensions. It also seems to alter the output when refresh rates don't match. If you don't want to lose quality, make sure all computer outputs match exactly with your desired display options, including refresh rate. +This device carries audio from your computers. You can hear any one of the inputs, or a mix of all inputs. My monitor has acceptable built-in speakers, and played sound from the computers right away, without having to add external speakers or setting up anything special. Less clutter! +The only complaint I have is that my monitor does not turn off when the computers go to sleep. You can see it's still on (backlight bleeds a little), stays on all night, and never turn off. For some strange reason, the monitor's own internal sleep timer does not engage, almost like it's still receiving a signal. I have to manually turn off the matrix switch (via remote control as there is no power button) in order for my monitor to turn off. ## Features - Quad Multi Viewer 4K: Supports 4 HDMI input sources to HDTV or display with fast real-time switching up to 4K@60Hz. 4 in 1 HDMI Switch, Optical Output, L/R Output - FULLY COMPATIBLE This HDMI MultiViewer Switch 4x1 is compatible with game consoles such as PlayStation, Xbox One, Nintendo, Roku, DVD, Blue Ray, desertcart Fire TV Players, Cable TV, Chromecast and many other HDMI devices - Audio supported: DTS Digital, Dolby Digital, LPCM, Dolby True HD, Master Audio, Passthrough 2-channel.
