text: did not work well with my equipment...Panasonic DVD recorder; Sony media player; Sony AV receiver; Radeon video card with HDMI for my computer and CISCO DVR for fiber TV...most devices showed as black screen; my 3 port unit worked well with all of these but the 5 port unit did not want to recognize most of these devices; returned this unit and replaced with the Sabrent 5 port unit and all these devices were recognized immediately and the Sabrent switched worked fine.
