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. (P169)

■ 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.
