A:AnswerMine works very good. We had Zoom on our computer and after I plug it into the computer I tried it out and it worked. It also works with Cortana on Windows 10 with no problems.
A:AnswerNO. I believe the key to whether you can use the virtual background is a function of your computer processor. In my case, my processor is fine (Intel i7) but it only has a 3rd generation chip. When I had trouble getting on Virtual Background I did some research and it turns out that for an i7 you need at least a 6th generation chip or, if you have a green screen, then at least a 4th generation chip. So you could have the greatest webcam int he world and it wouldn't help you use the Zoom virtual background. But I have to say that I am happy with this webcam. It is a very reasonable price and it seems to really do the job.
A:AnswerThis depends upon how thick the monitor is at the top. Most taper toward the top such that the top edge is less thick, and a webcam should work well in that situation. For some "business" style monitors I've noticed that the top edge is quite "thick" or deep... and the mount that comes with most webcams isn't going to adapt to that. Basically, the mount has a rubberized base under the camera, with a lip that goes over the front of the monitor. The rest of the mount is a hinged arm that you adjust so that its rubberized foot presses against the back of the monitor. The camera is held in place on top by the lip, and on the bottom by the rubberized foot pressing against the monitor back. For that to work, the monitor needs to be thinner toward the top. I suspect you could do some adaptation with Velcro strips or something like that, should the monitor be thick at the top.
