A:AnswerYep, that's exactly how I use this sometimes. You may need an external dock to connect it with the VGA cable, but it should work fine. I have used mine with a 2010 VGA monitor and a 2019 MacAir.
A:AnswerIf you have the HDMI double-ended cable, and use this particular cable, and have the old connections that require the male end, then you will need this cable. Double-check all your needs before purchasing but it sounds like you will need this cable.
A:Answermost tv’s don’t have HDMI outputs. The HDMI jacks are usually inputs to the tv. Before you try it make sure the tv actually has an HDMI output. I bought mine to connect the cable box to a projector and it works perfectly.
A:AnswerYes, the HDMI connector on this product plugs into your HDMI output on the computer and the cable from the VGA device plugs into the VGA connector side.
