Transparent proxy. It tells websites that it is a proxy server and it will pass along your IP address anyway. Anonymous proxy. It will identify itself as a proxy, but it won't pass your IP address to the website. Distorting proxy. It passes along an incorrect IP address for you, while identifying itself as a proxy. High Anonymity proxy.
It is also called Display Settings, which refers to the number of pixels displayed across the width of your computer monitor or data projector image. The most common display settings are 800 x 600 and 1024 x 768 while the default resolution of PowerPoint is 720 x 540 (almost the same as digital video).
As long as that is an optical resolution and not interpolated (digitally zooming in), 1200 dpi is totally enough resolution to scan paper prints. In the chart I created at the bottom of this post, you will see that I never recommended a DPI higher than 1200.
