Presets. There are seven Color Mode presets including Dynamic, Presentation, Theatre, Photo, and sRGB along with black- and white-board options. Dynamic and Presentation have a little more green bias than the others, but if color accuracy is important, Photo and sRGB have sufficient brightness for many rooms.
Automatic Iris . It is unusual to find an auto iris in such a low-cost projector, but it does add to the projector's video performance by improving contrast as scene brightness varies. Its operation is sometimes audible, but given the VS220's fan noise, most audience members will not be aware of the iris' operation. If iris noise is an issue, simply disable it in the Image menu.
Connectivity . While there is a wide variety among the rear panel connectors, there is only one VGA connector that serves dual purposes as a computer or a component video input. In addition, there is an HDMI input, a composite and S-video jack, audio jacks, and both USB-A and USB-B connectors.
Computer-free Presentations. If you have a photo collection or a short video stored on a USB device, you can connect directly to the USB-A connector without the need of a computer. The slideshow feature supports .jpg, .bmp, .gif, and .png formats.
Lamp Life In normal mode, lamp life is 4,000 hours, but switching to Eco mode extends that time to 5,000 hours without significant brightness reduction.
USB Connectivity. You can avoid the one VGA connector limitation by connecting your computer via the USB-A connector.
Maintenance. The VS220 has air filters that need to be changed when dirty, and the side grills should be vacuumed occasionally. Lamp replacement is easy as the lamp assembly can be removed from the top of the projector making maintenance simple even if the VS220 is ceiling mounted.
Warranty. The VS220 carries a warranty of one year.
