HDMI splitters, HDMI switches, adapters, couplers, “HDMI to HDMI,” and “HDMI to DVI” are products a lot of computer techs know about. I’m sure my husband and our son-in-law know what they are, too. But I don’t know anything about them. That’s why it’s so nice to have relatives who know so much about computers. I actually have three relatives who I see often or on a regular basis that help me with anything I need done on the computer. And that’s really nice since I’m on the computer every day. By the way, if you are needing any of the products mentioned above, then you might want to check out Firefold whose top priority is customer service.
