Multi Input 4K Projection
■ Definition of 4K
4K refers to high-resolution video with a horizontal resolution of about 4,000 pixels,
which is four times the resolution of full HD (1920 x 1080).
Although 4K is a convenient description, it encompasses several different
resolutions, such as 3840 x 2160, 3840 x 2400, 4096 x 2160, and 4096 x 2400.
(4096 x 2160 is also referred to as Ultra HD, and 3840 x 2400 as WQUXGA.)
The projector supports resolutions up to 4096 x 2400. For details, check the table of
supported signals. (

■ 4K Support Using Digital Signals and Multiple Inputs
The projector is equipped with DVI-D and HDMI (1.4) inputs for digital signals.
However, these signals cannot be used as-is for 4K projection.
DVI-D is classified as single-link or dual-link, depending on the dot clock. Projecting
resolutions with a dot clock higher than 165 MHz requires a dual-link plug and
cable.
The following resolutions are supported.
• 1920 x 1200 (single-link; vertical frequency: 60 Hz)
• 2560 x 1600 (dual-link; vertical frequency: 60 Hz)
• 4096 x 2160 (dual-link; vertical frequency: 24 Hz)
However, most current computers are limited to a
maximum DVI-D output resolution of 2560 x 1600.
For HDMI 1.4, the following resolutions are supported.
• 1920 x 1080 (vertical frequency: 60 Hz)
• 3840 x 2160 (vertical frequency: 24 Hz / 25 Hz / 30 Hz)
• 4096 x 2160 (vertical frequency: 24 Hz)
To avoid the limitation with DVI-D that a single signal line cannot carry video with a
resolution of 4096 x 2400 (vertical frequency: 60 Hz) even with a dual-link cable,
the projector enables you to project multiple lines of input at once. This feature is
called Multi Input mode.
