cabling, also offers a PC
maker the option of
splitting the four data
lanes up in pairs. One
pair can be used for
general I/O and one
utilized specifically for
video. What this means is
that essentially 38.7Gbps
will be allocated for video
and another 38.7Gbps
for data, cutting down
the available video
configurations to this:- Three 4K (3,840 x 2,160) displays
@144Hz and 30 bpp 4:4:4 HDR (with DSC) - Two 4K x 4K (4,096 x 4,096) displays
(for AR/VR headsets) @120Hz and 30 bpp
4:4:4 HDR (with DSC) - Three QHD (2,560 x 1,440) @120Hz
and 24 bpp 4:4:4 (no compression) - One 8K (7,680 x 4,320) display @30Hz
and 30 bpp 4:4:4 HDR (no compression)
The open question now is how desktop,
notebook, and chip makers will implement
DP 2.0, or whether they’ll choose HDMI
over DP, or vice versa. About the only
answer we have comes from Intel, which
publicly touted its contribution of the
Thunderbolt 3.0 standard to support DP
2.0. That, at least, should mean you’ll see
DP 2.0 support in products powered by
Intel’s Core processors.

- One 10K (10,240 x 4,320) display

Dual-display resolutions: - Two 8K (7,680 x 4,320) displays
@120Hz and 30 bpp 4:4:4 HDR (with DSC) - Two 4K (3840 x 2160) displays @144Hz
and 24 bpp 4:4:4 (no compression)
Triple-display resolutions: - Three 10K (10,240 x 4,320) displays
@60Hz and 30 bpp 4:4:4 HDR (with DSC) - Three 4K (3,840 x 2,160) displays
@90Hz and 30 bpp 4:4:4 HDR (no
compression)
Using the USB-C connector in what’s
known as DP Alt Mode, as opposed to the
HDMI 2.1 supports higher resolutions, new HDR features, and game-
smoothing variable refresh rates.
