There are thousands of Converters from all possible combinations. Even Having some IT background, I was fooled by these convincing “converters” to think that they will work, simply as that.
There are just simple cables that one end is digital & the other end is analog (or some other totally different tech) and let you think that it will work, just like that. Let me tell you something, almost all PASSIVE converters DO NOT work.
And there is the expensive type that advertise their true comparability and charge you a leg or arm.
And there is this,
I almost gave up trying to hook up a monitor with VGA to my Laptop (HDMI only) cause the converters seemed to over 100$. I ordered this and it works like a charm.
No External Power needed, but even if I do, the micro USB cable is provided. If you want, you can get the audio out from this device too (I don't see why anyone would do that, anyways).
Note: I lose video signal rarely for few seconds and it gets back up. Not annoying or a major issue if you are not a hardcore gamer or using this to fly a drone like Predator. :p
I totally recommend this product and is definitely got more than the "kick for the buck"
