Q: 4. Will this work going from projector vga to media player hdmi?

A: No, the ATEN VC180 VGA to HDMI Converter with Audio is not bi-directional, so it can only convert a VGA input to an HDMI output. If you are needing to convert your media player's HDMI signal to VGA for your projector's input, the QVS HDMI to VGA Video Converter with Audio (BH #QVXHDVA) would work.

Q: 5. Thumderbolt to USB 2.0 hub on my MacBook since I use most of the other ports for power and external monitors. I need a KVM switch for KB/mouse because Universal Control stopped working for me. Will this device work if plugged into the USB 2.0 hub with a thunderbolt to USB 2.0 cable?

A: The ATEN US3310 is not designed for use with Thunderbolt ports or Thunderbolt devices, and may not work as intended in this scenario. It may be possible if connected to Thunderbolt generation 3 or higher, but the switch is designed specifically for USB 3.0/USB 3.1 and is not intended for use with a USB 2.0 host connection.

A: Yes, the ATEN CS1964 4-Port 4K Triple Display KVMP Switch will keep the signal active so that there is no window reformatting when switching between computers.

Q: 10. Would this work with a USB mic between a Mac & a PC?

A: Yes, the ATEN US3342 could be used with a USB microphone, but switching will not be instant as each computer will take a moment to recognize and switch to the new audio device. You will also likely hear a popping sound through your headphones every time you switch. If applications like video games or streaming services are running when the audio device is switched, they may become unresponsive while the computer changes configuration.
