Related Questions and Answers

Q: 1. Will this play one input like a blue ray player to output 4 displays is this how this devise works?

A: This product from Smart-AVI is both a Video Wall Controller and a Matrix Switcher. It has 4 inputs and 4 outputs. When used as a Video Wall you can set it so one of the inputs is split across 4 screens set up as a 2x2 Video Wall. As a Matrix Switcher you can assign any input to go to any output. Since this product is HDCP compliant it will work with a Blu-Ray Player as well.

Q: 2. If I have a pair of RCA inputs (coming from right and left outputs from a turntable), can this unit send both inputs (right and left) to the optical output (to get stereo sound)?

A: The Inday DA4X-R SPDIF 4x1 Digital Audio Switcher does not feature the ability to combine or mix inputs to be sent out of the device together. Because they would be summed coming out of the single optical or coax output anyhow, perhaps summing the stereo signal before it feeds the DA4X-R would allow you to achieve your desired outcome. Also note that this unit is expecting a digital signal not often found directly on turntable output connections themselves.

Q: 3. If a computer is connected to an input and no output is active: Will the computer still detect that it's connected to a monitor?

A: No, unless the MuxLab 4x4 4K60 HDMI Matrix Switch is producing n actual outputting signal, a computer will not see any signal until such action is taken by the switch.

Q: 4. Will this work with a streamdeck?

A: The ATEN 4x4 4K UHD HDMI Matrix Switch would not be compatible with an Elgato Streamdeck as the switch is only controllable via RS-232.

Q: 5. Will this mount to a sound equipment rack?

A: Yes, the MuxLab 4x4 4K60 HDMI Matrix Switch ships with rack mount ears included. The included ears allow mounting in standard 19" racks.

Q: 6. so example this will play blue-ray player with example 3 tv or 3 monitors hooked up in the input device and play it out of the 3 outputs I want to know before I buy if these are not splitters?

A: This Smart-AVI product is both a Video Wall Controller and a Matrix Switcher. A Matrix Switcher allows you to send any input to any output. This has 4 inputs and 4 outputs. You can set it to have 1 input go to all 4 outputs or every input to go to a different output.

Q: 7. How clean is the switching on this unit?

A: It will not be clean when switching between inputs and outputs on this Matrix Switcher. For that you would need to look in to seamless switcher. We offer B&H # GEHDSL444, which is a 4x4 Seamless Matrix for HDMI from Gefen.https://bhpho.to/2vhS6I4

Q: 9. How to present 4 different ppt slides in a 4 monitor video wall?

A: This switcher can be configured in a few different ways. In picture-in-picture mode this switcher will allow you to have 4 different signals on 4 different monitors. So you could connect 4 computers, assign each to a screen and display 4 different PowerPoint slides that way. You can also set this as a 2x2 Video Wall. That means you would have a signal from one source spread out over the 4 screens. PowerPoint will not allow you to show 4 slides at a time, so you would need to create a custom slide or image that has 4 slides on it and make sure you have it appropriately sized and positioned on the screen.

Q: 10. Is the 4th hdmi a true video port? I have one sun that needs to keep it's keyboard, but video would be fine switched though kvm

A: The 4th port is for a MHL device like a compatible smartphone, or tablet.
