Does it work over a computer screen?

Yes- but you have to hold it about an inch from the screen. I use it at work- some of the data in our data bases use a font that is ridiculously small. I hold the magnifier and get my info then put it down. If you wanted to use it non stop to read multiple screens, that may be more difficult.

No. It only work's from DVI to HDMI. I thought the same thing as u. Wouldn't do that so I sent it back.

No. The product goes around the edges and behind the Kindle. Nothing over the screen.

It will extend the screen just like any dual-monitor capable video card would. I tried it on mine just to double check!

Not sure but touchscreen usually has connectivity via USB connection between PC and monitor.

Yes. The cord allows you to display the exact copy of your computer screen to your television. Go for another brand though. This cord is terrible

It depends on if you are sending the main monitor out to the screen. If so, then yes.

Yes it does. You could also use the adaptor for the desktop computer, so u could view your picture or videos more bigger screen.

No. This will mirror your screen not expand it. If you want to add another screen you will need either thunderbolt or a usb graphics adapter.

Not sure but don't see why it wouldn't work. all these are are a pen like instrument with a foam top on it to touch the screen.

I haven't tried it, but it should. You can switch it to become a remote mouse for your screen. I needed a second one to replace a pointer that didn't work after a year. This one has held up a long time and I use it daily in a classroom.

Yes it worked for me. I had stepped on the screen and ruined it. Ordered this, then took it to a small private computer shop and the fixed it

Yes - sort of. On my Samsung monitor and 3 year old HP Pavillion, the USB glass overlay seems to loose its registration after a few days of non-on/off use. It has have the USB unplugged and the machine re-booted to function correctly again, which it does.

Hmm. I'm not entirely sure. It may, the screen is quite large, but you may have some slight clipping.

yes this works with a desktop. I just tried it at 16' from the usb transmitter it was still working ok, that was about as far as I could get and still see the screen in the room I am using it, but it seemed like it would probably go at least a bit further since there was still no lag.
