Questions about this item

Which HDMI sources can I connect to the two 19-pin female inputs on this VS221HD4KA?

Any two HDMI source devices such as a media player, game console, or PC with an HDMI output can be plugged into the two 19-pin female ports on the switch.

Will my 1080p display work with the 4K 30 Hz output of this switch?

Yes, the switch is backward compatible with high-definition 1080p, so a 1080p display will receive a supported resolution from the HDMI output.

How do I confirm the switch is passing 4K 30 Hz and 7.1 surround sound to my display?

Check the display on-screen menu to verify it reports a 3840x2160 resolution at 30 Hz and that your audio receiver indicates a 7.1 surround sound signal.
