If you talk to computer technicians, they will often tell you that USB to VGA adapters do not work. They will say that they place too much stress on your graphics card, etc. But I'm very happy to say that the Insignia adapter really works beautifully. From the minute I plugged it in to my old laptop, my big flat screen monitor lit up and it's been perfect ever since. I couldn't be happier.

It’s been an expensive covid 19 for the electronics in my house hold this little Device saved me from going out and buying a hole new lap top.. if only the cracked iPad screen was as easy of a fix!

I have expanded my computer up to 4 monitors. Takes a little tweaking to configure all four, and it works.

I was hooking up a second monitor to my home computer. There was an HDMI port on the back of the computer, so I thought it would be easy. Hah! After failure and subsequent research, I discovered that this was only an HDMI port in. Why would you do that, HP? Anyway, got this adapter, hooked it up to a USB port on the computer, ran a VGA cable to the second monitor, installed the appropriate driver, and it worked great. Not exactly plug-and-play, but close enough.
