Resolution:
The resolution of a projector is the maximum number of image points (pixels) that a projector can display based on its naturally existing technology, i.e. without conversion or cropping of the image. The native resolution is the number of pixels that a projector physically has to display the image. A projector usually interpolates a resolution when it receives an image signal with a higher resolution than the native one. If this is the case, there may be a lack of image detail or general blurring in the displayed image. If a projector receives an image signal with a lower resolution than the native, it also interpolates, it scales the image up to the native resolution, calculates corresponding additional pixels, if possible without changing the image information. The disadvantage here is that although the image is displayed larger than fed, the original individual pixels may become much more visible as they are multiplied by the conversion.

4K:
4K refers to the resolution of 3840 x 2160 or Ultra High Definition Television (UHDTV). This resolution corresponds to 4 times the resolution of Full HD. To record films with this resolution, special cameras are needed that can record at around 8 megapixels (4K).

Full HD:
The term Full HD is used to describe devices that can physically display or output HDTV signals in full (1920 x 1080 pixels).

1080p:
1080p is the specification of the vertical picture lines. Among other things, it refers to the resolution 1920 x 1080. The "p" in this case means full frames, so all picture lines are displayed simultaneously.

1080i:
1080i is the specification of the vertical picture lines. The "i" in this case means fields. This signal is usually displayed interpolated (e.g. by devices with a 1280 x 720 HDready resolution). The interpolation digitally adds pixels, but also offers a slight blurring. In contrast, 1080p playback uses full frames.

Format:
The projected image is output in a format (aspect ratio) specified by the projector. The format is also determined by the resolution of the projector (see also the entry "Resolution"). The screen format is usually selected on the basis of the format of the beamer image. The most common formats are 4:3, 16:9 and 16:10.

WLAN:
WLAN (Wireless Local Area Network) refers to a wireless network. For example, projectors or displays can be connected wirelessly to various sources (notebooks, smartphones, etc.) to realise wireless image transmission. In some cases, additional components (dongles/adapters) are required for this if a wireless connection is not directly supported.

AirPlay:
Apple's AirPlay technology is used for wireless transmission of content, such as music and videos, from iOS and Mac devices. These can also be receiver devices such as speakers, AV receivers and stereo systems or TVs. Streaming also works from an iOS device to a matching receiver. The protocol developed by Apple can also be licensed by other manufacturers.

iProjection:
With the free Epson iProjection app, projectors can be operated remotely and office content and photos can be projected. The app is compatible with current Epson business projectors and can also be used as a practical remote control. Other features of this functionality include searching for available projectors, volume control, mute, and a freeze function to freeze the current image of a presentation. The most important Office contents, such as Word, Excel, PowerPoint, Keynote and PDF files, are supported and can be played back directly from the medium. Images in JPEG and PNG format can also be presented directly. The Epson iProjection app is available for download free of charge from the Apple App Store and the google Play Store.

Easy MP:
A special network function from Epson. The Easy MP function allows you to present efficiently over multiple computers via an existing network. Easy MP allows you to transfer a presentation, images as well as audio data via the network and thus receive a selection from various sources in the network.
