The useful distinction
Understand the requirement.
Passive DisplayPort-to-HDMI conversion requires a source with DisplayPort dual-mode (DP++) support. [C044A]
DP2HD4KADAP is listed as passive, with a DisplayPort input and HDMI output; its source must support DP++ HDMI/DVI pass-through. [C044B]
The passive DP2HD4KADAP sheet lists 3840 x 2160 at 30 Hz and no HDR support. [C044C]
VESA limits passive DisplayPort to HDMI or DVI adapter operation to DisplayPort source devices with DP++ capability; equipment documentation must establish that feature. [C044D]

DisplayPort to HDMI: passive adapter class facts and limitations
DP2HD4KADAP — Passive; 3840 × 2160 at 30 Hz [C044B][C044C]
Passive conversion
DP++ source support is a separate requirement for passive DisplayPort→HDMI. [C044D]
Verified device list
Not included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.
This is a scoped requirements guide, not an interoperability certification. It does not test hardware, calculate an arbitrary display timing, or replace the exact product documentation. A missing capability stays unknown.
Before you connect
What to check
Verify DP++ at the source.
Check the passive adapter’s supported direction and mode.
Use the correct class of active conversion when the passive prerequisites are absent.
Record the exact adapter model and documented input/output before treating the two connector ends as a usable path.
DP2HD4KADAP: DisplayPort output with DP++ → HDMI input. DP++ HDMI/DVI pass-through is required at the source. Documented DP-source to HDMI-display path; not a reverse HDMI-source solution.
Source-scoped mode, not a system guarantee
3840 × 2160 at 30 Hz. This model lists no HDR support. Compare all three documented examples in the Display adapter direction field reference.

Why does my passive DP-to-HDMI adapter produce no picture?
What the evidence saysA passive conversion depends on DP++ capability at the DisplayPort source.
What is still unknown
It does not make an HDMI output into a DisplayPort source; neither the connector nor passive adapter guarantees the intended mode.
Check before proceeding
Confirm the source is DisplayPort output, not HDMI.
Verify DP++ in the actual source documentation.
Check the specific adapter rating and downstream display input.
C044D / source-linked claim: VESA limits passive DisplayPort to HDMI or DVI adapter operation to DisplayPort source devices with DP++ capability; equipment documentation must establish that feature.
